  With the technology described above, each time an element is added, removed, or a specification is changed in the system, it is necessary to change the model of each element built on the computer so as to correspond to the addition, removal, or specification change of the element. is there. Such a model change is complicated.

  An object of the present invention is to provide an element that can easily cope with expansion, removal and specification change of elements in a system when operating information related to the system, for example, simulation in a system including a plurality of elements. A data processing apparatus associated with each other and a system including a plurality of the data processing apparatuses.

The data processing device according to the first aspect of the present invention is one of a plurality of data processing devices that are connected to each other so as to be able to communicate with each other and that are each associated with one element that performs actual work, and that is associated with itself. Management information storage means for storing management information related to the actual work of the element, processing numerical value storage means for storing a processing numerical value indicating a scheduled completion time of the work related to the element in the simulation, and the processing numerical value of itself based on the management information Stored in the processing numerical value storage means between the plurality of data processing devices, the processing numerical value storage means for storing a common processing numerical value common to each of the data processing devices, a rank determining section for determining the rank of the processing numbers, and order storage means for storing the self of the order determined, the order of the self And a ranking updating means for updating said order determination means, the ranking is initialized to the stored the own rank 1 in the storage means, the own processing numeric other of said data processing apparatus Each time the other processing numerical value transmitted from the other data processing device is received, in the case of ascending order determination in which the rank is determined according to the ascending order of the processing numerical value, the self-processing numerical value is received when the number greater than the process number, in the case of descending decision to determine therefore the ranking in the descending order of the processing numbers, when the own processing number is less than the processing numerical value to the received, stored in the rank storage means The ranking is determined by lowering the ranking of the self by one, and the processing numerical value changing unit is configured to change the processing numerical value of the self to the common processing when the ranking of the self is determined to be 1. In the case of determining the descending order, storing the common processing numerical value as a numerical value in the common processing numerical value storing means, transmitting the common processing numerical value to the other data processing apparatus, and increasing the own processing numerical value in the ascending order determination. Is changed to a smaller numerical value, and when the rank of the self is determined to be 2 or less, the received common process numerical value is stored in the common process numerical value storage means, and the rank update means has the rank of the self 1. When the processing numerical value changing unit changes the processing numerical value to a larger value in the case of the ascending order determination, or to a smaller numerical value in the case of the descending order determination. An update notification means for transmitting the changed processing numerical value to the other data processing device; and when the changed processing numerical value is received from the other data processing device, the ascending order decision If the self-processed numerical value is smaller than the received processed numerical value, and the descending order is determined, the self-processed numerical value is larger than the received processed numerical value. The ranking is updated by moving up, and a first update unit that transmits the update result to the other data processing device and the update notification unit change the changed processing numerical value to the other data processing unit. When transmitted to the device, every time the update result is received, the update result indicates that the other data processing device that transmitted the update result has moved up the rank in the update, A second updating unit that sequentially updates the rank of the self by lowering the rank of the self by one; and once the rank is determined by the rank determination unit After it is characterized by determining the self-ranking by the ranking updating means.

According to the present invention, each data processing device determines a processing numerical value related to the operation of system information from the management information of the associated element and performs data communication with other data processing devices. Since information related to the system is operated on the basis of common processing values common between apparatuses, even if an element is added, removed, or a specification is changed, it is not necessary to change the model of the element. In this way, when operating information related to the system, it is possible to easily cope with the addition, removal, and specification change of elements. Further, since the order of the processing numerical values is determined by receiving the processing numerical values of other data processing apparatuses and sequentially comparing them, the order of the processing numerical values can be easily determined.
In addition, it is possible to update its own ranking by using its own ranking stored in each data processing device. For this reason, it is possible to more easily determine the rank of the processing numerical value of itself.
Furthermore, each data processing apparatus determines the scheduled completion time of the work related to the element in the simulation from the management information of the associated element as a processing numerical value, and performs data communication with other data processing apparatuses while performing simulation communication. Since the simulation proceeds based on the common processing time, which is a common processing value, even if elements are added, removed, or specifications are changed, it is not necessary to rebuild the simulation model, and it can be handled easily. .

In the data processing device according to a second aspect of the present invention, in the first aspect of the invention, when the ranking of the self is 1, the processing numerical value changing means increases the processing numerical value of the self when the ascending order is determined. When the descending order is changed to a smaller numerical value, the data processing device whose self rank is 2 or less due to the change is smaller than the own processing numerical value when the ascending order is determined. Further, when it is necessary to change the numerical value to a larger numerical value at the time of the descending order determination, the apparatus further comprises temporary rank update means for temporarily updating the rank of the self, and the rank temporary update means has the rank of the self The order is temporarily updated when it is necessary to change the self-processed numerical value to 2 or less and a smaller numerical value for the ascending order determination and a larger numerical value for the descending order determination. The temporary update notification means for transmitting to the other data processing device together with the processing numerical value changed by itself and the ranking before the temporary update, and the temporary update notification means. In the case of receiving the information that needs to be updated, in the ascending order determination, the self rank is higher than the notified rank, and the own processing numerical value is larger than the notified processing numerical value. When the descending order is determined, when the self rank is higher than the notified rank and the own processing numerical value is smaller than the notified processing numerical value, the self rank is lowered by one. A temporary update unit that temporarily updates the rank of the self and transmits the temporary update result to the other data processing device; and the rank of the self is 2 or less and the processing numerical value of the self , When it becomes necessary to change to a smaller value in the case of the ascending order determination and to a larger value in the case of the descending order determination, each time the temporary update result is received, the temporary update result is changed to the temporary update result. When the other data processing apparatus that has transmitted indicates that the rank of its own has been lowered by one in the temporary update, the rank of its own is sequentially provisionally updated by raising its rank by one. A second temporary update means, and when the rank update means determines the rank of the self, the rank temporary update means temporarily updates the rank of the self before the determination, The rank is determined by the rank update means.

According to the second aspect of the invention, since the data processing device with the ranking of 1 has changed the processing numerical value, the data processing device with the ranking of 2 or less needs to change the processing numerical value so that its ranking becomes higher. Even if this occurs, a change in rank due to the data processing device changing the process numerical value can be processed as a temporary update of the rank.

In the data processing device according to a third aspect of the present invention, in the first aspect , when the self rank is 1, the processing numerical value changing means increases the processing numerical value of the self when the ascending order is determined. When the descending order is changed to a smaller numerical value, the data processing device whose self rank is 2 or less due to the change is smaller than the own processing numerical value when the ascending order is determined. Further, when it is necessary to change the numerical value to a larger numerical value at the time of the descending order determination, the apparatus further comprises temporary rank update means for temporarily updating the rank of the self, and the rank temporary update means has the rank of the self The order is temporarily updated when it is necessary to change the self-processed numerical value to 2 or less and a smaller numerical value for the ascending order determination and a larger numerical value for the descending order determination. Temporary update notification means for transmitting to the other data processing apparatus together with the processing numerical value that has been changed, the ranking before the temporary updating of itself, and initializing the ranking of the self to 1; When the provisional update notification means receives that the order needs to be provisionally updated, when the ascending order is determined, the self order is higher than the notified order, and the self processing numerical value is When the numerical value is larger than the notified processing numerical value, when the descending order is determined, the self rank is higher than the notified rank, and the own numerical value is smaller than the notified processing numerical value. In some cases, the ranking of the self is temporarily updated by lowering the ranking of the self by one, and the descending order is determined when the notified processing numerical value is larger than the processing numerical value of the self when the ascending order is determined. When the notified processing numerical value is smaller than the processing numerical value of the self, a first temporary updating means for transmitting the result of the comparison as a temporary updating result to the other data processing device, and the self Is lower than 2 and the self-processed numerical value needs to be changed to a smaller numerical value in the case of the ascending order determination, and to a larger numerical value in the case of the descending order determination. Each time it is received, when the ascending order is determined, the temporary update result is larger than the processing numerical value of the other data processing apparatus that has transmitted the temporary update result. When the temporary update result indicates that the processing numerical value of the self is smaller than the processing numerical value of the other data processing apparatus that has transmitted the temporary update result, Second temporary updating means that sequentially provisionally updates the rank of the order, and when the rank updating means determines the self rank, the rank temporary update means determines the self rank before the determination. After the temporary update, the rank is determined by the rank update means.

According to the third invention, it is possible to obtain the same effect as the second invention in a different algorithm and the second invention.

And an operation parameter storage unit 507.

Here, in the present embodiment, the work refers to each step of manufacturing the substrate that the working device 2 is in charge of. It shows that it is inspected for properness, and that the substrate is cut into a set external dimension. The operation parameter storage unit 507 stores operation parameters for specifying the operation of the operation mechanism 501. Here, the operation parameter is information unique to each work apparatus 2 related to the specification of the operation mechanism 501. Specific operation parameters include the drive voltage and drive signal of the actuator that moves the probe for inspecting the substrate surface provided in the operation mechanism 501, the type of drill that cuts out the substrate, and the set rotation of the motor that drives the drill Number and driving torque. The operation control unit 503 controls the operation mechanism 501 so that the actual work stored in the work content storage unit 506 is performed based on the operation parameter stored in the operation parameter storage unit 507.

  The simulation unit 505 simulates the operation status when the work device 2 performs work using the operation mechanism 501. In this embodiment, based on the operation parameters stored in the operation parameter storage unit 507, the operation completion schedule time T when the operation content stored in the operation content storage unit 506 is sequentially updated is sequentially updated. The operation status of 501 is simulated. This scheduled completion time T corresponds to the processing numerical value of the present invention.

  The scheduled completion time storage unit 508 stores its scheduled completion time T.

  The scheduled completion time changing unit 509 stores its own scheduled completion time T as the common time W in the common time storage unit 510 when the own rank P is determined to be 1, and this common time W is stored in other data. It is transmitted to the processing device, and its own scheduled completion time T is changed to a later time, and the received common time W is stored in the common time storage unit 510 when its rank P is determined to be 2 or less. .

  The common time storage unit 510 stores a common time W common to the respective work devices 2.

  The rank determination unit 511 initializes its own rank P stored in the rank storage unit 512 to 1 and transmits its own scheduled completion time T to the other work device 2, and is transmitted from the other work device 2. Each time another scheduled completion time T is received, when the scheduled completion time T is later than the received scheduled completion time T, the ranking P stored in the rank storage unit 512 is decremented by one. To determine the rank P.

  Further, when the scheduled completion time T and the received scheduled completion time T are the same time, the rank determining unit 511 further receives the identification number ID from the work device 2 that transmitted the received scheduled completion time T, When the identification number ID is larger than the received identification number ID, it is processed that the scheduled completion time T is later than the received scheduled completion time T. When the identification number ID is smaller than the received identification number ID, Processing is performed assuming that the scheduled completion time T of itself is earlier than the received scheduled completion time T.

  The rank temporary update unit 514 includes a temporary update notification unit 519, a first temporary update unit 520, and a second temporary update unit 521.

  The provisional update notification unit 519 needs to change its own scheduled completion time T to an earlier time by an interruption operation such as acceptance of a processed board (hereinafter, workpiece) having a rank P of 2 or less. When it occurs, the fact that the order P needs to be provisionally updated is transmitted to the other work devices 2 together with the self-completed scheduled completion time T and the order P before the provisional update.

  When the first temporary update unit 520 receives that the order P needs to be provisionally updated by the provisional update notification unit 519, the first provisional update unit 520 has its own order P higher than the notified order P, and its own scheduled completion time. When T is later than the scheduled completion time T notified of, T is temporarily updated by lowering its own rank P by one, and this temporary update result N is transmitted to other work devices 2.

Furthermore, when the work device 2 having its own rank P of 2 or less needs to change its own scheduled completion time T to an earlier time, the rank update unit 513 temporarily updates its rank P. The order P is determined by

  The identification number storage unit 515 stores an identification number ID unique to the work device 2.

  The rank storage unit 512 stores the rank P determined by the rank determination unit 511.

The operation mechanism 501 and the control unit 502 of the present embodiment correspond to the element and the data processing device of the present invention, respectively. Unlike the conventional computer having the model of the operation mechanism 501, the control unit 502 associated with the operation mechanism 501 has a remarkable feature that the management information of the actual operation mechanism 501 can always be used.

  Hereinafter, the progress of the simulation will be described in detail.

  First, the situation where the order P is determined from step S1 at the start of simulation to step S4 where the simulation has progressed in three stages will be described with reference to FIGS.

  FIG. 3 is a diagram illustrating determination of the order P at the start of simulation. An arrow extending to the right side in the figure indicates the progress of time. In addition, the vertical line on the left side in the figure indicates the simulation start time. At the start of the simulation, the work device 2a has a work on the simulation to be machined (hereinafter referred to as a virtual work), and a scheduled completion time T for completing the virtual work is indicated by Ta-1. Similarly, for work devices 2b and 2d, respective scheduled completion times T are indicated by Tb-1 and Td-1. The work device 2c does not have a workpiece to be machined at the start of simulation, and the scheduled completion time T is provisionally determined. In the present embodiment, the scheduled completion time storage unit 508 has an allowable maximum value. . When each work device 2 receives a simulation start message from the management terminal 4, the rank determining unit 511 receives the scheduled completion time T of the other work device 2, and sets the scheduled completion time T as its own scheduled completion time T. Compared with, the self rank P is determined. In FIG. 3, as shown at the right end, the rank P of the scheduled completion time T is determined as 2, 3, 4, and 1 for the work devices 2a to 2d, respectively. The determination of the rank P in step S1 corresponds to the determination of the rank P by the rank determination unit 511 of the present invention.

  FIG. 4 illustrates step S2 in which processing of the virtual workpiece is completed by the working device 2d from the start of the simulation and the virtual workpiece is transferred to the working device 2b, and the determination of the rank P in the next step S3. FIG. When processing of the virtual work is completed in the work device 2d and delivery to the work device 2b occurs, the virtual work is processed at a time Tb-2 earlier than the scheduled completion time Tb-1 of the virtual work of the work device 2b in Step S1. Need to accept. Since such an interruption work has occurred, the order temporary update unit 514 needs to temporarily update the order P of the scheduled completion time T of the virtual work of the work device 2. The work device 2b that has accepted the virtual work transmits the rank P before the temporary update of itself and the scheduled completion time Tb-2 of the accepted work changed by its own interrupt work to the other work devices 2. The other work device 2 compares the received rank P and scheduled completion time T with its own rank P and scheduled completion time T, and temporarily updates its rank P. Further, the temporary update result N is transmitted to the other work device 2, and the work device 2 b temporarily updates its rank P with the temporary update result N. The result of the temporary update of the rank P is shown under S2 in FIG. 4 and is 3, 2, 4, 1 for the work devices 2a to 2d, respectively. The change in the rank P from step S1 to step S2 corresponds to the temporary update of the rank P of the present invention.

  In the next step S3, the work device 2d whose temporarily updated rank P is 1 sets its own scheduled completion time T to the scheduled completion time T of the next virtual work, and other work devices 2 The completion scheduled time T is transmitted. Each work device 2 that has received the scheduled completion time T updates its rank P by comparing the received scheduled completion time T with its scheduled completion time T. Further, the update result M is transmitted to the other work device 2, and the work device 2 d updates its rank P with the update result M. The result of the update of the order P is shown under S3 in FIG. 4 and is 2, 1, 4, 3 for the work devices 2a to 2d, respectively. The change in the rank P from step S2 to step S3 corresponds to the update of the rank P of the present invention.

  FIG. 5 is a diagram for explaining the update of the rank P in step S4 in which the work device 2b has advanced the scheduled completion time T of the next virtual work to the original scheduled completion time Tb-1 from step S3. After completing the acceptance of the virtual workpiece at time Tb-2, the work device 2b continues machining of the original virtual workpiece, and sets the scheduled completion time Tb-1 of the virtual workpiece machining as its own scheduled completion time T. Thereafter, the update of the rank P from step S2 to S3 described above is the same, and the result of the update of the rank P is 1, 2, 4 for each of the work devices 2a to 2d as shown under S4 in FIG. 3.

  Next, the simulation flow will be described based on the flowcharts shown in FIGS. In the simulation, the control unit 502 of each work device 2 executes a flow described below. For the sake of simplicity, the main body that executes the flow will be described as the work device 2 below.

  FIG. 6 is a diagram for explaining the overall flow of the simulation. When the simulation is started in accordance with an instruction from the management terminal 4, all the work apparatuses 2 perform initial processing (S101). Then, based on the order P determined in the initial process (S102), if the order P is 1, the SIM rights holder process is performed (S103). If the order P is 2 or less, the SIM participant Processing is performed (S104). Thereafter, each work device 2 determines whether or not to continue the simulation (S105), and if so, based on the rank P updated in the SIM right holder process or the SIM participant process, the SIM right is again obtained. Person process or SIM participant process.

  FIG. 7 is a diagram for explaining the flow of the initial process. When the initial process is started, the work device 2 first receives a simulation end time TE from the management terminal 4 (S201). This end time TE is used when determining whether or not to continue the simulation in the subsequent processing. Next, the work device 2 is scheduled to complete the processing of the virtual workpiece or the reception of the virtual workpiece based on the presence / absence of the virtual workpiece to be machined, the state, the presence / absence of the acceptance of the virtual workpiece, and the state of the own operation mechanism 501. Time T is determined (S202). If there is no virtual workpiece to be machined, the scheduled completion time storage unit 508 can accept the scheduled completion time T of itself as shown in the scheduled completion time Tc-1 of the working device 2c in FIGS. The latest time. When the determination of the scheduled completion time T is completed, the following process (rank determination process) is executed to determine its own rank P. The work apparatus 2 initializes its own rank P to 1 (S203), and then transmits its own scheduled completion time T together with its own identification number ID to another work apparatus 2 (S204). Thereafter, each time the scheduled completion time T and the identification number ID transmitted from the other work device 2 are received (S205), the following processing is performed. First, if the self-scheduled completion time T is later than the received scheduled completion time T2, the own rank P is decremented by one (S206, S209). When the self-scheduled completion time T is the same time as the received scheduled completion time T2, if the self-identification number ID is larger than the received identification number ID2, the self-order P is decremented by one, Otherwise, the self rank P is maintained (S206, S207, S208, S209). If the self-scheduled completion time T is earlier than the received scheduled completion time T2, the self-order P is maintained (S206, S207). Such processing is repeated until the scheduled completion time T and the identification number ID are received from all the work devices 2 (S210).

  In this embodiment, the management terminal 4 confirms the transmission of the scheduled completion time T and the identification number ID of all the work apparatuses 2 and transmits a message indicating that all reception is complete to the work apparatus 2.

  In this way, when the all reception completion message is received, the initial process ends, and each work device 2 completes the determination of the scheduled completion time T and its rank P of its own work.

  FIG. 8 is a diagram for explaining the SIM right holder process. When the SIM right holder process is started, the self-scheduled completion time T is first substituted into the common time W (S301), and transmitted to another work device 2 (S302). This common time W is a time that can be set only by the work device 2 (hereinafter, SIM right holder) whose rank P is 1, and is shared among all the work devices 2. When the common time W is earlier than the end time TE, it is determined whether or not the virtual workpiece that has been processed needs to be transferred to the work device 2 that is in charge of processing of the next process. (S303, S304). In this embodiment, only the work device 2d in charge of component mounting in the final process does not need to transfer the virtual work to another work device 2. When it is necessary to deliver the virtual workpiece, the identification number ID3 of the work device 2 in charge of the next process is selected, and the acceptance completion scheduled time T3 when the acceptance of the virtual workpiece is completed to the work device 2 having the identification number ID3. Is transmitted (S305). Thereafter, it waits for a sort completion message to be received from the accepting work device 2 (S306). When the sort completion message is received, based on the common time W, based on the presence / absence / status of the virtual workpiece to be processed again, the presence / absence of acceptance of the virtual workpiece, and the status of the own operation mechanism 501, A scheduled completion time T for completing the acceptance of the virtual work is determined (S307). Then, the following processing is executed to update its own ranking P. First, the work device 2 transmits the determined scheduled completion time T to another work device 2 (S308, update notification process). Then, every time an update result M transmitted from another work apparatus 2 is received with respect to the transmitted scheduled completion time T (S309), the update result M is added to its own rank P, so that its own The rank P is updated (S310). This update is repeated until the update result M is received from all the work devices 2 (S311, second update process). The first update process will be described later.

  In the present embodiment, the management terminal 4 confirms the transmission of the update result M of all the work devices 2 other than the work device 2 that has transmitted the scheduled completion time T, and notifies the work device 2 that is the SIM right holder to Send a complete message.

  When the common time W is later than the end time TE, the work device 2 that is the SIM right holder transmits an end message to end the simulation to the other work devices 2.

  In this way, a reception complete message is received or an end message is transmitted, and the SIM right holder process ends, and the work device 2 that has become the SIM right holder sets and transmits the common time W, and ends the simulation. And the update of its own scheduled completion time T and its rank P is completed.

  9, 10 and 11 are diagrams for explaining SIM participant processing. The SIM participant process is a process corresponding to the update notification process and the second update process described above, a process executed when virtual work is accepted, and a temporary update of the rank P is notified by the acceptance of the virtual work. The process is divided into three parts. These parts correspond to FIGS. 9, 10, and 11, respectively.

  First, a process corresponding to the update notification process and the second update process will be described with reference to FIG. This part corresponds to the SIM participant rank update process, and when the scheduled completion time T2 transmitted by the work device 2 that has become the SIM right holder is received (S401), the scheduled completion time T of itself is the received completion If the time is earlier than the scheduled time T2, the update result M is set to 1 (S402, S403). Otherwise, the update result M is set to 0 (S402, S404). Then, only when the update result M is set to 1, the rank P is incremented by one (S405). Thereafter, the update result M is transmitted to the other work device 2, and the SIM participant process is terminated (first update process).

  Next, with reference to FIG. 10, processing executed when virtual work is accepted will be described. When the virtual work acceptance completion scheduled time T3 is received (S501), when the received scheduled completion time T3 is earlier than the scheduled completion time T (S502), the scheduled completion time T is received. The completed completion time T3 is changed (S503). Then, the following processing is performed. First, the changed completion scheduled time T and its own rank P are transmitted to another work device 2 (S504, temporary update notification process). Each time the temporary update result N returned from the work device 2 that has received the scheduled completion time T and the rank P is received (S505), the temporary update result N is subtracted from the own rank P to determine its own rank. Then, temporary update is sequentially performed (S506). This is repeated until it is received from all the work devices 2 other than the work accepting work device 2 (S507, second temporary update process).

  In this embodiment, the management terminal 4 confirms the transmission of the temporary update result N of all work devices 2 other than the work device 2 that has transmitted the virtual work acceptance completion scheduled time T3, and accepts the virtual work. A message indicating completion of all reception is transmitted to the device 2.

  Thereafter, a sort completion message indicating completion of the temporary update of the rank is transmitted to the other work devices 2 (S508). Note that if the received virtual work acceptance completion scheduled time T3 is later than its own scheduled completion time T, there is no need to temporarily update the rank, and only the sort completion message is sent to the other work devices 2. Transmit (S508). After the sort completion message is transmitted, it waits for the scheduled completion time T to be transmitted from the work device 2 that has become the SIM right holder for updating the rank P.

  Finally, with reference to FIG. 11, a description will be given of processing in a case where it is notified that a temporary order update is necessary due to acceptance of a virtual work. When the order P2 and the scheduled completion time T2 are received from the work device 2 that accepts the virtual work (S601), the following processing is performed. The temporary update result N is set to 1 only when its own rank P is higher than the received rank P2 (S602) and when its own scheduled completion time T is later than the received scheduled completion time T2 (S603). (S605), and lowers its own rank P by one (S607). In other cases, the temporary update result N is set to 0 (S604, S606) and transmitted to the work device 2 that accepts the workpiece (S608, first temporary update process). After that, as in the case of the process executed when accepting the virtual work, it waits for the scheduled completion time T to be transmitted from the work device 2 that has become the SIM right holder for the order update.

  In addition to the scheduled completion time T, the virtual workpiece acceptance completion scheduled time T3, and the rank P and the scheduled completion time T received from the other work devices 2, an end message for ending the simulation is received (S609). The SIM participant process is terminated.

  Here, a modified embodiment of the present embodiment will be described. The change mode is different from the present embodiment only in the procedure for temporarily updating the order P. Hereinafter, the same portions as those of the present embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only portions different from the present embodiment are described.

  In the SIM right holder process in the modified form of FIG. 12, after the virtual work delivery completion scheduled time T3 is transmitted (S305), the temporary update result N is automatically set to 1 (S701). (S702). In addition, in the SIM participant processing in the modified form of FIG. 13, after receiving the virtual work acceptance completion scheduled time T3 (S501) and transmitting its own scheduled completion time T and rank P for temporary update of the rank In (S504), the self rank is initialized to 1 (S703). Then, by adding the received temporary update result N to the own rank P, the own rank P is provisionally updated (S704). Correspondingly, in the SIM participant processing of FIG. 14, when the own rank P is higher than the received rank P2 (S602) and the own scheduled completion time T is earlier than the received scheduled completion time T2. Only in (S603), the temporary update result N is set to 1 (S705). In other cases, the temporary update result N is set to 0 (S706, S707) and transmitted to the other work devices 2 (S608). In the present embodiment, when its own rank P is lower than the received rank P2, its own scheduled completion time T will not be earlier than the received scheduled completion time T2, and as a result, the provisional update result N Is set to 1 when the received scheduled completion time T2 is later than the scheduled completion time T of itself.

  According to the present embodiment, one of a plurality of control units 502 that are connected so as to be capable of data communication with each other and associated with the operation mechanism 501 stores management information related to the actual work of the operation mechanism 501 associated with the operation unit 501. The management information storage unit 504, the scheduled completion time storage unit 508 that stores the scheduled completion time of work, the scheduled completion time change unit 509 that changes the scheduled completion time T based on the management information, and the respective control units 502 A common time storage unit that stores a common time W, a rank determination unit 511 that determines a rank P of the scheduled completion time T stored in the scheduled completion time storage unit 508 among the plurality of control units 502, and a determination And a rank storage unit 512 for storing the rank P of the self. The rank determination unit 511 initializes its own rank P stored in the rank storage unit 512 to 1, transmits its own scheduled completion time T to the other control unit 502, and is transmitted from the other control unit 502. Each time another scheduled completion time T is received, when the scheduled completion time T is later than the received scheduled completion time T, the ranking P stored in the rank storage unit 512 is decremented by one. The scheduled completion time changing unit 509 stores the scheduled completion time T in the common time storage unit 510 as the common time W when the own ranking P is determined to be 1, and the common time W is transmitted to another control unit 502, and its own scheduled completion time T is changed to a later time, and when its own rank P is determined to be 2 or less, the received common time W is set as the common time storage unit. Store in 510.

  According to the present invention, each control unit 502 determines the work completion scheduled time T in the simulation of the circuit board manufacturing system 1 based on the management information of the associated operation mechanism 501, and the other control units 502 In order to perform a simulation related to the circuit board manufacturing system 1 based on the common common time W between the control units 502 while performing data communication between the control units 502, even if the work device 2 is added, removed, or changed in specifications, It is not necessary to change the model of the operating mechanism 501. As described above, when the simulation related to the circuit board manufacturing system 1 is performed, it is possible to easily cope with the addition, removal, and specification change of the work device 2. Further, since the order P of the scheduled completion time T is determined by receiving the scheduled completion times T of the other control units 502 and sequentially comparing them, the order P of the scheduled completion time T can be easily determined. Can do.

  The control unit 502 of the present embodiment further includes a rank update unit 513 that updates its own rank P. The rank update section 513, when its rank P is 1, is a scheduled completion time change unit 509. When the self-scheduled completion time T is changed to a later time, the update notification unit 516 that transmits the changed scheduled completion time T to the other control unit 502, and the completion changed from the other control unit 502 When the scheduled time T is received, when the own scheduled completion time T is earlier than the received scheduled completion time T, the ranking P is updated by raising the ranking P by one, and the update result M When the updated completion time T is transmitted to the other control unit 502 by the first update unit 517 and the update notification unit 516, each time the update result M is received, This update When another control unit 502 that has transmitted the update result M from the result M indicates that the order P has been raised in the update, the order P is sequentially updated by lowering its own order P by one. 2, and once the rank determination unit 511 determines its own rank P, the rank update section 513 determines its own rank P.

  According to this, the own rank P can be updated using the own rank P stored in each control unit 502. Therefore, the rank of the scheduled completion time T can be determined more easily than in the first invention.

  In the second embodiment, the control unit 502 according to the present embodiment further determines that the scheduled completion time T is changed to a later time by the scheduled completion time changing unit 509 when the ranking P is 1 in the second invention. In addition, when the control unit 502 whose own rank P is 2 or less due to this change needs to change its own scheduled completion time T to an earlier time, the temporary rank update for temporarily updating its own rank P The rank temporary update unit 514 temporarily updates the rank P when the rank P is 2 or less and the scheduled completion time T needs to be changed to an earlier time. The temporary update notification unit 519 that notifies the other control unit 502 of the necessity completion time T, its own changed scheduled completion time T, and its previous rank P before temporary update, and the rank P is set by the temporary update notification unit 519. Need to be provisionally updated When the notice is notified, the self rank P is equal to the rank P when the rank P is higher than the notified rank P and the scheduled completion time T is later than the notified scheduled completion time T. The first rank updating unit 520 that temporarily updates its own rank P and transmits this temporary update result N to the other control section 502, and its own rank P is 2 or less, and When it is necessary to change the scheduled completion time T to an earlier time, every time the temporary update result N is received, the temporary update result N is temporarily updated by the other control unit 502 that has transmitted the temporary update result N. , The second temporary update unit 521 sequentially provisionally updates the own rank P by raising the own rank P by one. When the update unit 513 determines its own rank P, this Before determination, after the temporary updating its own rank P by ranking the temporary updating unit 514, the ranking updating unit 513 determines the self-ranking P.

  According to this, since the control unit 502 with the order P of 1 has changed the scheduled completion time T, the control unit 502 with the order P of 2 or less needs to change the scheduled completion time T at an earlier time. Even if it occurs, the control unit 502 can process the change of the rank P due to the change of the scheduled completion time T as a temporary update of the rank P.

  The control unit 502 according to the modified form of the present embodiment changes the scheduled completion time T when the scheduled completion time T is changed to a later time when the own ranking P is 1. Further, when the control unit 502 having its own rank P of 2 or less needs to change its own scheduled completion time T to an earlier time, it further includes a rank temporary update section 514 that temporarily updates its own rank P. The rank temporary update unit 514 needs to temporarily update the rank P when its rank P is 2 or less and the scheduled completion time T needs to be changed to an earlier time. To the other control unit 502 and the temporary update notification unit 519 that initializes the own rank P to 1, and the temporary update. The order P is provisionally updated by the notification unit 519. If the self-ranking P is higher than the notified rank P and the scheduled completion time T is later than the notified scheduled completion time T, Decrease P by one to temporarily update its own rank P. When the notified scheduled completion time T is later than the scheduled completion time T, the result of this comparison is set as a temporary update result N The first temporary update unit 520 that transmits to the other control unit 502 and the temporary update when the own rank P is 2 or less and the scheduled completion time T needs to be changed to an earlier time. Each time the result N is received, the temporary update result N indicates that the scheduled completion time T is later than the scheduled completion time T of the other control unit 502 that has transmitted the temporary update result N Lowers its own rank P by one, A second provisional update unit 521 that sequentially provisionally updates the rank P, and when the rank update unit 513 determines the own rank P, the rank provisional update unit 514 determines the own rank before the determination. After temporarily updating P, the rank update unit 513 determines its own rank P.

  According to this, the same effect as this embodiment can be obtained by a procedure different from that of this embodiment.
