Description

  In the present invention, when a production facility having a plurality of manufacturing processes is damaged by a predetermined disaster, out of one or two or more recovery operations necessary for resuming the production activity of each manufacturing process, the production activity of the production facility is resumed. The present invention relates to a critical recovery operation determination system, method, and program for determining which recovery operation is the critical recovery operation that most affects the time required for the recovery.

  If a production facility is damaged due to a disaster such as an earthquake or flood, not only the repair cost but also a loss due to the suspension of production activities will be incurred. Therefore, it is desirable to restart production activities quickly after a disaster occurs.

  On the other hand, in production facilities, production is often performed by combining a plurality of manufacturing processes. In addition, some recovery operations for resuming the production activity of each manufacturing process can be completed quickly, and others can take a long time. Therefore, in order to minimize the period from the occurrence of a disaster to the resumption of production activities, which recovery work takes time to recover and is the critical recovery work that has the greatest impact on the period until production activities resume. It is important to understand accurately.

By the way, Patent Document 1 discloses a technique for evaluating damage to a production facility due to an earthquake and evaluating the number of days and the amount of loss required to restore the production facility. However, this technology does not clarify which recovery work takes time and what procedure can be used to efficiently recover the production facility.

  When a production facility with multiple manufacturing processes is damaged by a specific disaster, out of one or more recovery operations required for resuming production activities in each manufacturing process, the period required for resuming production activities at the production facility It can be determined which recovery operation has the most critical critical recovery operation.

=== First Embodiment ===
When a production facility with multiple manufacturing processes is damaged by a specific disaster, out of one or more recovery operations required for resuming production activities in each manufacturing process, the period required for resuming production activities at the production facility The critical recovery operation determination system 1 that determines which recovery operation has the most impact on the critical recovery operation is, for example, a plan for recovery operation for early resumption of production activity after a disaster occurs, or existing production It can be used to support the creation of effective reinforcement plans for facilities.

  FIG. 1 is an arrow diagram for explaining a manufacturing process of a production facility that is a target for using the critical recovery work determination system 1 of the first embodiment and a recovery work necessary for recovery of each manufacturing process.

As shown in the figure, this production facility comprises eight manufacturing processes, manufacturing processes A to H, in the order of processes.
The production process A corresponds to the “first production process” in the claims, and is a process for producing the intermediate product A upon receipt of raw materials. In the manufacturing process A, it is necessary to supply lifelines of electricity, communication and data in addition to raw materials and predetermined facilities / equipment.
The production process B is a second production process, and is a process for producing the intermediate product B upon receiving the input of the intermediate product A. In the manufacturing process B, in addition to the supply of the intermediate product A and predetermined facilities / equipment, it is necessary to supply the lifeline of electricity, gas, water, communication, and data.
Hereinafter, similarly, each manufacturing process C to G newly manufactures an intermediate product by processing / transferring the intermediate product manufactured in the immediately preceding manufacturing process. In addition, each manufacturing process C to G requires supply of intermediate products B to F and predetermined facilities / equipment, as well as supply of lifelines such as electricity, gas, water, communication, and data. .
The manufacturing process H is a final manufacturing process, and is a process for receiving the intermediate product G and manufacturing a finished product. In addition, in the manufacturing process H, in addition to the supply of the intermediate product G and predetermined facilities / equipment, it is necessary to supply the lifeline of electricity, gas, water, communication, and data.

  When a production facility having the manufacturing processes A to H described above has suffered a disaster such as an earthquake and suffered a loss in each manufacturing process, restoration work was resumed to resume production activities as shown in the figure. X01 to X08 and recovery operations X91 to X95 are required.

  Restoration work X01-X08 is for restoring facilities / equipment related to each manufacturing process A-H when disaster such as earthquake occurs and each manufacturing process suffers loss as shown in the figure It is a recovery work. The recovery operations X91 to X95 are recovery operations for the lifelines of electricity (X91), gas (X92), water supply (X93), communication (X94), and data (X95).

  As shown in the figure, in order to resume the production activity of the manufacturing process A, not only the restoration of the facilities and equipment of the manufacturing process A is required by the recovery work X01, but also the recovery work X91 and the recovery work X94. Therefore, it is necessary that the restoration work X95 is completed and the supply of lifelines for electricity, communication, and data is secured. Similarly, in order to resume the production activities of the respective manufacturing processes B to H, not only the recovery operations X02 to X08 are required, but also the supply of the lifeline needs to be secured by the recovery operations X91 to X95. It is.

  FIG. 2 is a diagram showing a hardware configuration of the critical recovery work determination system 1 according to the embodiment of the present invention. The critical recovery work determination system 1 is configured by connecting a computer such as a PC (Personal Computer) or a server to peripheral devices, and includes a CPU (Central Processing Unit) 10, a memory 11, a storage unit 12, and a recording medium reading unit. 13, a communication interface 14, an input means 15, an output means 16, and the like.

  The CPU 10 reads the program stored in the storage unit 12 into the memory 11 and executes it. The memory 11 is, for example, a DRAM (Dynamic Random Access Memory). The storage unit 12 is, for example, a hard disk drive. The recording medium reading unit 13 is a drive device that reads a program and data recorded on a recording medium 17 such as a CD-ROM (Compact Disc Read Only Memory). The communication interface 14 is a network connection device such as a NIC (Network Interface Card). The input means 15 is, for example, a keyboard or a mouse. The output unit 16 is, for example, a display or a printer.

  Next, the system configuration of the critical recovery work determination system 1 according to the first embodiment will be described.

  FIG. 3 is a block configuration diagram illustrating a configuration of the critical recovery work determination system 1 according to the first embodiment. As shown in the figure, each process production period storage unit 40, each recovery work content storage unit 42, each recovery work period storage unit 44, the first manufacturing process restart period calculation unit 20, and the second manufacturing process restart period calculation unit 22. , A third manufacturing process resumption period calculation unit 24, a fourth manufacturing process resumption period calculation unit 26, a critical recovery work determination unit 28, and an input reception unit 32. Each functional unit 20 to 32 is realized by the CPU 10 reading and executing a program stored in the storage unit 12, and each storage unit 40 to 44 is constructed on the storage unit 12.

  Each process production period memory | storage part 40 memorize | stores the period required for production in a manufacturing process about each of each manufacturing process AH. For example, the period required for production in the manufacturing process A is a normal state in which the production activity can be performed (that is, a state where the production process A is not damaged by a disaster or the like). This is the period until the intermediate product A is completed. Each manufacturing process B to H is similarly stored.

  Each restoration work content storage unit 42 stores information indicating a necessary restoration work for each of the manufacturing processes A to H. FIG. 4 is a configuration diagram of data stored in each restoration work content storage unit 42. For example, in order to resume production activities for the manufacturing process A, as shown in FIG. 1, the recovery work X01, the electrical recovery work X91, the communication recovery work X94, and the data recovery work X95 related to the facilities and equipment of the manufacturing process A are performed. Each restoration work content storage unit 42 stores the production process A restoration work X01, the electrical restoration work X91, the communication restoration work X94, and the data restoration work X95 in association with the production process A. Each manufacturing process B to H is stored in the same manner.

  Each restoration work period storage unit 44 stores a period required for each restoration work X01 to X08, X91 to X95 in association with each restoration work X01 to X08, X91 to X95. FIG. 5 is a configuration diagram of data stored in each recovery work period storage unit 44. For example, if the period required from the start of the recovery work X05 related to the facility / equipment of the manufacturing process E to 30 days is 30 days, 30 days are stored in association with the recovery work X05.

  By the way, the period required for the restoration work varies depending on the degree of damage to the production facility, and the degree of damage varies depending on the scale of the disaster. Here, using existing disaster damage assessment systems, for example, various earthquake damage prediction systems (for example, Quake Maper (registered trademark)) for earthquake damage, various disasters (Tokai earthquake, The disaster scale (Nankai earthquake, XX fault zone earthquake, XX river flood, etc.) and the damage level of the production facility are calculated in advance, and the calculation results are stored in association with those disasters in each restoration work period storage unit 44.

  In addition, when disaster countermeasures are taken in the production facility, the period required for each restoration work X01 to X08 is shortened according to the contents of the countermeasures. Therefore, in this case, the input receiving unit 32 receives an input of a period required for each recovery work X01 to X08 after the countermeasure, and each recovery work period storage unit 44 newly stores the period after the countermeasure.

  The first manufacturing process resumption period calculation unit 20 stores, for the manufacturing process A, information indicating the recovery work necessary for recovery of the first manufacturing process stored in each recovery work content storage unit 42 and each recovery work period storage. Based on the period required for each recovery operation stored in the unit 44, the period of the recovery operation that requires the longest period of recovery operations required for the recovery of the manufacturing process A is defined as the minimum period required for resuming the production activity of the manufacturing process A. calculate. Specifically, the longest period of the recovery operations X01, X91, X94, and X95, which are recovery operations necessary for the recovery of the manufacturing process A, is the minimum period required for resuming the production activity of the manufacturing process of the manufacturing process A. calculate. This is because all of the recovery operations X01, X91, X94, and X95 need to be completed in order to resume the production activity of the manufacturing process A.

  The second manufacturing process resumption period calculation unit 22 includes, for each manufacturing process from the manufacturing process B to the manufacturing process H, in order from the manufacturing process B, a minimum period required for resuming the production activity of the manufacturing process immediately before the manufacturing process, Information indicating the period required for production in the manufacturing process immediately before the manufacturing process stored in each process production period storage unit 40, and the recovery work necessary for recovery of the manufacturing process stored in each recovery work content storage unit 42; Based on the period required for each recovery operation stored in each recovery operation period storage unit 44, a minimum period required for resuming the production activity of the manufacturing process is calculated. Specifically, the sum of the minimum period required for resuming the production activity of the manufacturing process immediately before the manufacturing process and the period required for production in the manufacturing process immediately before the manufacturing process stored in each process production period storage unit 40 The longest period among the period and the period of each restoration work necessary for the restoration of the manufacturing process is calculated as the minimum period required for resuming the production activity of the manufacturing process. For example, the minimum period required for resuming the production activity of the manufacturing process B is the minimum period required for resuming the production activity of the manufacturing process A and the production process immediately before the manufacturing process stored in each process production period storage unit 40. The minimum period required for resuming production activities in the manufacturing process is the longest period of the sum of the required periods and the periods X02, X91, X92, X93, X94, and X95 necessary for the recovery of the manufacturing process B. Calculate as period. Similarly, the minimum period required for resuming the production activity in each of the manufacturing processes C to G is sequentially calculated.

  The third manufacturing process resumption period calculation unit 24 calculates the period required for resuming the production activity of the final manufacturing process H calculated by the second manufacturing process resumption period calculation unit 22 and the final manufacturing process H stored by each process production period storage unit 40. Based on the period required for production in the manufacturing process G immediately before the production process G, the production activity in the manufacturing process G immediately before the final manufacturing process H is resumed so as not to affect the resumption of the production activity in the final manufacturing process H. The latest point of time that must be calculated (the point in time at which production activity of the latest manufacturing process G resumed from the point of occurrence of the disaster) is calculated. Specifically, the period required for production in the manufacturing process G stored by each process production period storage unit 40 is subtracted from the period required for resuming the production activity of the final manufacturing process H calculated by the second manufacturing process restart period calculation unit 22. As a result, the production activity resumption point of the latest manufacturing process G is calculated.

  The fourth manufacturing process resumption period calculation unit 26 resumes the production activity of the manufacturing process immediately after the manufacturing process in order from the manufacturing process F two steps before the final manufacturing process H to the first manufacturing process A. Based on the latest time point that must be generated and the time period required for production in the manufacturing process stored in each process production period storage unit 40, the latest time point at which the production activity of the manufacturing process must be resumed is calculated. To do. Specifically, in order from the manufacturing process F to the first manufacturing process A, each process production period storage unit starts from the latest time when the production activity of the manufacturing process immediately after the manufacturing process must be resumed. The latest production activity resumption time of the manufacturing process is calculated by subtracting the period required for production in the manufacturing process stored in 40. For example, the production activity resumption time of the latest manufacturing process F is subtracted from the latest production activity resumption time of the manufacturing process G calculated by the third manufacturing process resumption period calculation unit 24 from the time required for production in the manufacturing process F. To calculate. Further, the production activity restart time of the latest manufacturing process E is subtracted from the latest production activity restart time of the manufacturing process F calculated by the fourth manufacturing process restart period calculating unit 26 from the time required for production in the manufacturing process E. To calculate. Similarly, the production activity resumption time of each manufacturing process D to A is sequentially calculated.

  The critical recovery work determination unit 28 includes a minimum period required for resuming the production activity of each manufacturing process calculated by the first manufacturing process restart period calculating unit 20 and the second manufacturing process restart period calculating unit 22, and a third manufacturing process restart period. Based on the latest time point at which the production activity of each manufacturing process must be resumed calculated by the calculation unit 24 and the fourth production process resumption period calculation unit 26, the time period required to resume the production activity of the production facility is most affected. It is determined which recovery work is the critical recovery work to be given. Specifically, for all the manufacturing processes, the production activities of the manufacturing processes A to G calculated by the third manufacturing process restart period calculation unit 24 or the fourth manufacturing process restart period calculation unit 26 from the disaster occurrence point, respectively. From the period up to the latest time point at which the production process must be resumed, it is necessary at least to resume the production activities of the production processes A to G calculated by the first production process resumption period calculation unit 20 or the second production process resumption period calculation unit 22 When the difference obtained by subtracting the period is 0, it is determined that the recovery process of the manufacturing process that requires the most period is the critical recovery process.

  Next, a processing flow in the critical recovery work determination system 1 will be described. FIG. 6 is a diagram illustrating a processing flow in the critical recovery work determination system 1.

FIG. 7 is a diagram for explaining the results of processing performed according to the processing flow shown in FIG. In addition, the numerical value in the parenthesis beside each restoration work X01-X08, X91-X95 shows the period which each restoration work X01-X08, X91-X95 requires. N ₀ is the time of occurrence of the disaster and the time of starting the first recovery work, and corresponds to the time of calculation of the “latest time” in the claims. N ₀₁ indicates the start time of the manufacturing process A, and N ₀₂ indicates the end time of the manufacturing process A and indicates the start time of the manufacturing process B. Similarly, N _{03 to} N ₀₉ indicate the start time and end time of each of the production steps B to H. Furthermore, the numerical values shown in the “day” -shaped frame written in the vicinity of N _{01 to} N ₀₉ indicate the results calculated by the following processing.

First, in S602, the first manufacturing process resumption period calculation unit 20 calculates a minimum period required for resuming the production activity of the manufacturing process A. Of the recovery operations X01, X91, X94, and X95 required for resuming the production activity in manufacturing process A, the longest period is 30 days of recovery operation X01. The period is calculated as 30 days. This numerical value is as shown in the upper column of the “day” -shaped frame near N ₀₁ in FIG.

  Next, in S604, the minimum period required for resuming the production activities of the manufacturing processes B to H is sequentially calculated. The minimum period required for resuming production activity in manufacturing process B is the sum of the minimum period required for resuming production activity in manufacturing process A and the period required for production in manufacturing process A, and is necessary for recovery of manufacturing process B. Since the recovery work X93, which is the longest period among the recovery work X02, X91, X92, X93, X94, and X95, is 60 days, the minimum period required for resuming production activities in the manufacturing process B is 60 days. Calculated.

  Further, the minimum period required for resuming the production activity in the manufacturing process C is 61 days, which is the sum of the minimum period required for resuming the production activity in the manufacturing process B and the period required for production in the manufacturing process B. The minimum period required for resuming the production activity in process C is calculated as 61 days. Similarly, it is calculated as 63 days for the manufacturing process D, 65 days for the manufacturing process E, 66 days for the manufacturing process F, 90 days for the manufacturing process G, and 92 days for the manufacturing process H.

In S606, the latest period of manufacturing process G starts from the 92nd day (shown in the lower column of the “day” frame near _{N08 in} FIG. 7), which is the minimum period required for resuming production activities in manufacturing process H. Calculate when production activity resumes. It is calculated as 90 days after subtracting 2 days of the period required for production in the manufacturing process G from 92 days of the period required for resuming the production activity of the manufacturing process H. This numerical value is as shown in the lower column of the “day” shaped frame in the vicinity of N ₀₇ in FIG.

  In S608, the latest production activity resumption time of the manufacturing processes F to A is sequentially calculated. The production activity resumed at the latest manufacturing process F is 90 days after the latest production activity resumed at the manufacturing process G immediately after the manufacturing process F, by subtracting one day of the period required for production in the manufacturing process F. Calculated as 89 days. Hereinafter, similarly, it is calculated as 88 days for the manufacturing process E, 86 days for the manufacturing process D, 84 days for the manufacturing process C, 83 days for the manufacturing process B, and 82 days for the manufacturing process A.

In S610, it is determined which is the critical recovery work. The manufacturing process which becomes 0 by subtracting the numerical value of the upper column from the numerical value of the lower column shown in the “day” -shaped frame described in the vicinity of N _{01 to} N ₀₉ is the manufacturing process G (N ₀₇ ) It is a manufacturing process H (N ₀₈ ). Furthermore, the recovery work that requires the longest period of recovery work in the manufacturing process G is 90 days of the recovery work X07. Therefore, it is determined that the recovery operation X07, the manufacturing process G, and the manufacturing process H are critical recovery operations.

  Based on the determination result in S610, when measures are taken for locations related to the critical recovery work (S612: YES), the input reception unit 32 inputs the period required for each recovery work X01 to X08 after the measures. Accept (S614). On the other hand, if no measures are taken for the location related to the critical recovery work (S612: NO), the process ends.

  As described above, according to the critical recovery operation determination system 1 of the first embodiment, when a production facility having a plurality of manufacturing processes is damaged by a predetermined disaster, 1 necessary for resuming the production activity of each manufacturing process. Alternatively, it is possible to determine which of the two or more recovery operations is the critical recovery operation that has the greatest influence on the period required for resuming the production activity of the production facility. Further, according to the critical recovery work determination system 1, the second manufacturing process resumption period calculation unit 22 can calculate a period required for resuming the production activity of the entire production facility.

  As described above, if it is possible to determine which critical recovery work is performed, it can be used for effective disaster countermeasure decision making such as which part of the production facility should be repaired. In addition, by providing the input receiving unit 32, when a disaster countermeasure is taken for a production facility based on the determination result related to the critical recovery work, the period of the recovery work shortened by the disaster countermeasure can be input. Therefore, it is possible to further determine the critical recovery work after the disaster countermeasure. In addition, since it is possible to calculate the period required to resume production activities for the entire production facility after disaster countermeasures, the effectiveness of disaster countermeasures can be quantitatively grasped by comparing and examining the period required for resuming production activities before and after disaster countermeasures. be able to.

=== Second Embodiment ===
FIG. 8 is a block configuration diagram illustrating a configuration of the critical recovery work determination system 2 according to the second embodiment. As shown in the figure, in addition to the critical recovery work determination system 1, each recovery work breakdown work storage unit 46, breakdown work period storage unit 48, and each recovery work period calculation unit 30 are further provided. Each restoration work period calculation unit 30 is realized by the CPU 10 reading and executing a program stored in the storage unit 12, and the storage units 46 and 48 are constructed on the storage unit 12.

  Each restoration work breakdown work storage unit 46 stores work contents (break work) obtained by further subdividing the work contents of the respective restoration works X01 to X08. FIG. 9 is a configuration diagram of data stored in each recovery work breakdown work storage unit 46. For example, the restoration work X01 includes a breakdown work of repairing a building in the manufacturing process A (breakdown work X01a) and repairing equipment used in the manufacturing process A (breakdown work X01b). In this way, each recovery work breakdown work storage unit 46 stores the respective recovery works X01 to X08 and the breakdown work of each recovery work X01 to X08 in association with each other.

  The breakdown work period storage unit 48 stores a period required for each breakdown work in association with each breakdown work. For example, if the period required from the start of the recovery work to the completion of the breakdown work X01a is 7 days, 7 days are stored in association with the breakdown work X01a.

  By the way, the period required for the breakdown work varies depending on the degree of damage to the production facility, and the degree of damage varies depending on the scale of the disaster. Here, using existing disaster damage assessment systems, for example, various earthquake damage prediction systems (for example, Quake Maper (registered trademark)) for earthquake damage, various disasters (Tokai earthquake, The disaster scale of Nankai earthquake, XX fault zone earthquake, XX river flood, etc.) and the damage degree of the production facility are calculated in advance, and the calculation results are stored in the breakdown work period storage unit 48 in association with those disasters.

  In addition, when disaster countermeasures are taken in the production facility, the period required for each breakdown work is shortened according to the contents of the countermeasures. Therefore, in this case, the input receiving unit 32 receives an input of a period required for each breakdown work after the countermeasure, and the breakdown work period storage unit 48 stores the period after the countermeasure again.

Each restoration work period calculation unit 30 includes information indicating the breakdown work of each restoration work X01 to X08 stored in each restoration work breakdown work storage unit 46 and each restoration work X01 to X08 stored in the breakdown work period storage unit 48. Based on the period required for the breakdown work, the period required for each recovery work X01 to X08 is calculated. Specifically, the period of the longest breakdown work among the periods required for the breakdown work of each recovery work X01 to X08 is calculated as the period required for each recovery work X01 to X08. For example, there are two breakdown work X01a and breakdown work X01b in the recovery work X01. When the breakdown work X01a takes 7 days and the breakdown work X01b takes 30 days, the breakdown work requiring the longest period is the breakdown work X01b. Therefore, the period required for the recovery work X01 is calculated as 30 days.
In addition, each recovery work period storage unit 44 stores a period required for each recovery work X01 to X08 calculated by each recovery work period calculation unit 30.

  Next, a processing flow in the critical recovery work determination system 2 will be described. FIG. 10 is a diagram illustrating a processing flow in the critical recovery work determination system 2.

  First, in S1000, the periods required for the recovery operations X01 to X08 are calculated. The subsequent processes of S1002 to S1014 are the same as S602 to S614 of the first embodiment.

  As described above, even in the critical recovery operation determination system 2 of the second embodiment, when a production facility having a plurality of manufacturing processes is damaged by a predetermined disaster, 1 or necessary for resuming the production activity of each manufacturing process Among the two or more recovery operations, it is possible to determine which recovery operation is the critical recovery operation that most affects the period required to resume the production activity of the production facility.

  Furthermore, according to the critical recovery work determination system 2 of the second embodiment, the recovery work breakdown work storage unit 46 and the breakdown work period storage part 48 store the breakdown work of the recovery work X01 to X08. It is possible to examine in more detail the time required for the work.

=== Third Embodiment ===
FIG. 11 is an arrow diagram for explaining a manufacturing process of a production facility that is a target for using the critical recovery work determination system 1 and a recovery work necessary for recovery of each manufacturing process in the third embodiment. The manufacturing process in the first embodiment shown in FIG. 7 uses the intermediate product A manufactured in the manufacturing process A to manufacture the manufacturing process B, and uses the intermediate product B manufactured in the manufacturing process B. However, as shown in FIG. 11, the manufacturing process in the third embodiment is performed simultaneously in a part (manufacturing process C and manufacturing process D). It is double-tracked so that it can proceed in parallel. As described above, the critical recovery work determination system 1 can be used for a multi-track manufacturing process.

_{Incidentally, N 13 ~N 14, N 15} ~N 18, N 13 dashed arrows d1 connecting _{~N 16,} N 17 _{~N 18,} respectively, d2, d3, d4 in FIG. _{11, N 13} ~N _14, N ₁₅ a is _{~N 18, N} 13 ~N 16, intended to demonstrate the context of N 17 _{to N 18,} the work period is 0. That is, the broken arrows d1, d2, d3, and d4 cannot reach N ₁₄ and N ₁₆ unless they reach N ₁₃ (if the supply of the intermediate product B is not resumed in the manufacturing process B) (the manufacturing process C). And the production activity of the production process D is not resumed), N ₁₅ is reached and N ₁₇ is not reached (the supply of the intermediate product C is resumed in the production process C, and the intermediate product D is produced in the production process D). N ₁₈ cannot be reached (if the supply is not resumed) (the production activity of the production process E is not resumed).

  A specific processing flow in the third embodiment is the same as that in the first embodiment described with reference to FIG.

  In addition, regarding the manufacturing process C and the manufacturing process D, which are double-track manufacturing processes, the manufacturing process immediately before the manufacturing process C is the manufacturing process B, and the manufacturing process immediately before the manufacturing process D is also the manufacturing process B. The manufacturing processes immediately before the manufacturing process E are the manufacturing process C and the manufacturing process D.

  For example, for the manufacturing process E, the second manufacturing process resumption period calculation unit 22 calculates the sum of the period required for resuming the production activity of the immediately preceding manufacturing process C and the period required for production in the manufacturing process C, and the immediately preceding manufacturing process. The longest period among the sum of the period required for resuming the production activity in process D and the period required for production in manufacturing process D and the period of each recovery operation required for recovery of the manufacturing process is Calculated as the minimum period required to resume production activities.

  Further, the fourth manufacturing process restart period calculation unit 26 calculates, for example, the manufacturing process B by subtracting the period required for production in the manufacturing process C from the latest point in time when the production activity of the manufacturing process E must be restarted. The earlier time point of the time point and the time point calculated by subtracting the time required for production in the manufacturing process D from the latest time point at which the production activity of the manufacturing process E must be resumed is the intermediate point of the manufacturing process B. It is calculated as the latest point in time when the supply of the organism B must be resumed. Then, the manufacturing process is subtracted from the latest time point at which the supply of the intermediate organism B in the manufacturing process B has to be resumed to subtract the time required for production in the manufacturing process B stored in each process production period storage unit 40. Calculate the latest point in time at which B's production activity must resume.

  In the third embodiment, as shown in the second embodiment, each recovery work breakdown work storage unit 46, a breakdown work period storage unit 48, and each recovery work period calculation unit 30 are further provided, and a period required for the recovery work. You may consider in more detail.
