Description

TECHNICAL FIELD The present invention relates to a work instruction device and a work instruction method for instructing workers to perform necessary work.

Currently, when a failure occurs and repair work is performed, the site is restored according to the know-how of local workers and the procedure manual prepared in advance. However, depending on the customer, there are cases where the cost incurred by the above recovery method is unacceptable, and the work time is not sufficient. In addition, it was necessary for the local workers to select the necessary work and adjust the price and time.

In response to this, a technology has been proposed that calculates the maintenance fee based on information obtained from the elevator and submits this information to the customer so that the customer can determine whether or not this work is necessary. there is For example, in Patent Document 1, "Since the customer requests maintenance after examining the content of the preventive maintenance information sent from the maintenance fee calculation center 9 at any time, the maintenance fee can correspond to the guarantee desired by the customer. You can.”

Japanese Patent Application Laid-Open No. 2002-197215 (paragraph [0024], see FIG. 4, etc.)

However, since local workers have different experience and skills, the result of selecting the necessary work and adjusting the price and time differed depending on the local worker.

Further, in the technique described in Patent Document 1, it is necessary for the customer to determine the work content based on the required work and the associated costs based on the preventive maintenance information. However, when dealing with sudden breakdowns, it was necessary for local workers and related parties to select the necessary work and negotiate prices with customers. For example, when recovering from a sudden failure, it is necessary to consider various factors such as the details of the failure, time, and the number of workers to perform the recovery. Furthermore, since preventive maintenance information cannot be used to deal with sudden failures, local workers must work within the scope of customer approval while negotiating prices with customers.

In view of the above situation, there has been a demand for a method that minimizes the occurrence of price negotiations with customers and that can present necessary work to workers when a failure occurs in a monitoring target.

In order to solve the above-described problems, a work instruction device according to one aspect of the present invention is a work instruction device that instructs work to be performed in response to a failure that has occurred in an object to be monitored, wherein the content of a maintenance contract concluded with the object to be monitored is Based on the contract information that indicates the failure, set the priority for each work in the work list created for the failure, determine the order in which each work should be performed based on the priority, and work in which the order is reflected a work order determination unit that outputs a list;

According to at least one aspect of the present invention, when a failure occurs in an object to be monitored, it is possible to minimize price negotiations with customers and present necessary work to workers.

In this specification and the accompanying drawings, constituent elements having substantially the same function or configuration are denoted by the same reference numerals, and overlapping descriptions are omitted.

<1. one embodiment>
First, the overall configuration of a work support system including a work instruction device according to one embodiment of the present invention will be described.

FIG. 1 is a schematic diagram showing an overall configuration example of a work support system 1 including a work instruction device 20 according to one embodiment. The work support system 1 is composed of a field work unit 10 , a work instruction device 20 and a work terminal 30 .

The field work unit 10 has an elevator 11 to be monitored and a monitoring device 12 for monitoring the state of the elevator 11 . When an abnormality occurs in the elevator 11 , status data D<b>1 including information on the status of the elevator 11 is transmitted from the elevator 11 to the work instruction device 20 via the monitoring device 12 . The state data are, for example, output values of sensors installed in the elevator 11 .

The work instruction device 20 determines the work to be performed on the elevator 11 based on the status data D1 of the elevator 11 transmitted from the monitoring device 12 of the field work unit 10, and transmits the details of the work to the work terminal 30. do.

The work terminal 30 is a terminal used by the worker U for work such as inspection and repair, and displays (instructs) the worker U the content of the work transmitted from the work instruction device 20 . As the work terminal 30, a terminal such as a tablet terminal that can be carried by the worker U is used.

[Work instruction device]
Here, the work instruction device 20 will be described in detail.
The work instruction device 20 includes a work list creation unit 29 , a work order determination unit 26 and a management information database 27 . The work list creation unit 29 creates a work list necessary for a failure that has occurred in the elevator 11 (an example of a monitoring target). For example, the work list creation unit 29 includes a data management unit 21, a past case estimation unit 22, a causative device estimation unit 23, a work extraction unit 24, a past information database 25, a work order determination unit 26, a management information database 27, and a work master database. 28. In FIG. 2, each database is described as "DB".

The data management unit 21 receives status data D1 about the elevator 11 transmitted from the monitoring device 12 when a failure occurs in the elevator 11, and manages the collected status data D1 for each case. For example, when the data management unit 21 receives the state data D1 from the monitoring device 12, the data management unit 21 outputs the state data D1 to the past case estimation unit 22 and the causative device estimation unit 23 as a new case (case).

Based on the state data D1 input from the data management unit 21, the past case estimation unit 22 refers to the past information database 25 to estimate past similar cases, and outputs the estimation result to the work order determination unit 26. . A past similar case is, for example, a case that is considered to be the same failure. Here, information such as the name and management number of the applicable case is specified.
Based on the state data D1 input from the data management unit 21, the causative device estimation unit 23 refers to the past information database 25 to determine the cause of the elevator 11 becoming in the state indicated by the state data (i.e., failure). The device is estimated from information on past cases, and the result of estimation is output to the work extraction unit 24 .
Information about past cases is recorded in the past information database 25 in association with state data. For example, the past information database 25 records past cases, state data at that time, work contents (causing equipment and work to be performed), and the like. In addition, the past information database 25 stores state data collected for each case and the time required for the work.

The work extractor 24 extracts from the work master database 28 the work required for the causative device estimated by the causative device estimator 23 , and outputs the extraction result (work list) to the work sequence determiner 26 .
Work information is registered in the work master database 28 for each cause. For example, the work master database 28 associates and records the causative device and the work for the causative device.

The work order determining unit 26 sets priority to each work in the work list extracted by the work extracting unit 24 based on contract information indicating the details of the maintenance contract concluded with the elevator 11 . Then, the work order determination unit 26 determines the order in which each work in the work list should be performed based on the priority of each work, and outputs the work list reflecting the order. Thus, in this embodiment, the content of the customer's maintenance contract is used as a factor for determining the order of work. Details of the processing of the work order determination unit 26 will be described later.

In the management information database 27, contract information indicating the details of the contract concluded with the customer regarding maintenance by the maintenance company of the elevator 11 is recorded. For example, the types of maintenance contracts can be broadly classified into contracts in which additional costs are incurred in performing the target work (first contract) and contracts in which additional costs are not incurred (second contract). An example of the first contract is a POG (Parts Oil Grease) contract in which replacement of the causative equipment is charged. In POG contracts, the costs generally include periodic inspections and replacement of consumables within the range of management specifications, but additional costs are required for replacement and repair of other consumables and parts. Also, an example of the second contract is a full maintenance contract in which replacement of the causative device is free of charge. A full maintenance contract is a contract that includes replacement and repair of consumables and parts that occur during normal use, and no additional costs are incurred for these works.

[Work terminal]
The work terminal 30 includes a work sequence output unit 31 and a work result transmission unit 32 .
The work order output unit 31 outputs a work list reflecting the work order determined by the work order determination unit 26 to the display device 44 (see FIG. 2). The work order output unit 31 displays the work order in the work list on the display device, so that the worker U can confirm the work order. Note that the work order output unit 31 may output the work order not by display but by voice. After completing the troubleshooting, the worker U inputs the details of the work performed for the elevator 11 failure (work results) to the work terminal 30 .

The work record transmission unit 32 transmits the work record to the work instruction device 20 via the communication interface 47 (see FIG. 2) in order to register the work record of the worker U for the failure of the elevator 11 in the past information database 25. .

In the present embodiment, the elevator 11 is exemplified as a monitoring target, but various equipment and systems such as escalators and equipment constituting a plant system can be monitoring targets.

[Computer hardware configuration]
Next, the hardware configuration of the devices constituting the work support system 1 and the computers constituting the terminals will be described.
FIG. 2 is a block diagram showing a hardware configuration example of the computer 40. As shown in FIG. The hardware of the work instruction device 20 and the work terminal 30 is configured by the computer 40 shown in FIG. Note that the monitoring device 12 is also configured with the same hardware as the computer 40 shown in FIG.

The computer 40 is hardware used as a so-called computer. The computer 40 includes a CPU (Central Processing Unit) 41, a ROM (Read Only Memory) 42, and a RAM (Random Access Memory) 43, which are each connected to a bus. Further, computer 40 includes display device 44 , operation device 45 , nonvolatile storage 46 , and communication interface 47 .

The CPU 41 reads a program code of software that implements each function according to the present embodiment from the ROM 42, loads it into the RAM 43, and executes it. Variables, parameters, etc. generated during the arithmetic processing of the CPU 41 are temporarily written in the RAM 43 and read out by the CPU 41 as appropriate. Although the CPU 41 is used as the arithmetic processing unit, other processors such as an MPU (Micro Processing Unit) may be used.

The display device 44 is, for example, a liquid crystal display monitor, and displays a GUI screen, results of processing performed by the CPU 41, and the like. For example, a touch panel, a pointing device such as a mouse, a keyboard, or the like is used as the operating device 45, and the user can perform predetermined operations on the operating device 45 to input instructions. The operation device 45 generates an input signal according to the user's operation and supplies it to the CPU 41 . Note that the display device 44 and the operation device 45 may not be provided depending on the configuration of the device. For example, the work instruction device 20 and the monitoring device 12 may not require the display device 44 and the operation device 45 .

As the non-volatile storage 46, for example, HDD (Hard Disk Drive), SSD (Solid State Drive), flexible disk, optical disk, magneto-optical disk, CD-ROM, CD-R, magnetic tape, non-volatile memory, etc. are used. be done. The nonvolatile storage 46 stores an OS (Operating System), various parameters, and programs for making the computer 40 function. The ROM 42 and the non-volatile storage 46 can permanently record programs, data, etc. necessary for the operation of the CPU 41 .

In the work instruction device 20, the non-volatile storage 46 stores a program for the work instruction device 20 to operate as an application server that provides work instructions. Further, in the work terminal 30, a program is stored in the non-volatile storage 46 so that the work terminal 30 operates as a client terminal that displays work instructions.

For the communication interface 47, for example, a NIC (Network Interface Card), a modem, or the like is used, and various data are transmitted/received to/from an external device via a communication network such as a LAN or a dedicated line to which terminals are connected. is configured to allow As the communication interface 47, a communication interface compatible with wireless communication such as Wi-Fi (registered trademark) or LTE (Long Term Evolution) (registered trademark) may be used.

[Flow of processing by work order determination unit]
The flow of processing by the work order determination unit 26 will be described with reference to FIGS. 3 and 4. FIG.
FIG. 3 is a flow chart showing the flow of processing by the work order determination unit 26. As shown in FIG.

First, the work order determination unit 26 takes in the estimation result of the past case estimation unit 22 based on the state data D1 and the work list extracted by the work extraction unit 24 based on the state data D1 (S1).

Next, in order to use the past work record, the work order determination unit 26 acquires the response history (for example, the date when the target work was performed last time) of the same site (on-site work unit 10) from the past information database 25 (S2 ). Further, the work order determination unit 26 acquires the contract information of the site from the management information database 27 (S3).

Next, the work order determination unit 26 determines the order in which the work in the work list should be performed from the plurality of acquired information (S4). Then, the work order determination unit 26 transmits a work list reflecting the work order to the work terminal 30 (S5).

The worker U confirms the order of work in the work list presented on the work terminal 30, and performs work on the elevator 11 at the site. The worker U uses the operation device 45 to input the content of the actual work (work results) to the work terminal 30 . Finally, the work record transmission unit 32 of the work terminal 30 transmits the work record of the worker U to the work instruction device 20 , and the work record is registered in the past information database 25 . The registered work performance information can be used in the event of a subsequent failure.

[Work order determination process]
Next, the work order determination process in step S4 of FIG. 3 will be described.
FIG. 4 is a flowchart showing a detailed procedure example of the work order determination process in step S4. 4 will be described with reference to FIGS. 5 to 13. FIG. 5 to 6 and 8 to 9 are examples of POG contracts, and FIGS. 10 to 13 are examples of full maintenance contracts.

First, the work order determination unit 26 creates a work list for determining the work order based on the work contents extracted by the work extraction unit 24 (S11). The work list includes the work content extracted by the work extraction unit 24 and information on the expected work time and the arranged time calculated from the estimation results of the past case estimation unit 22 .

(In case of POG contract)
FIG. 5 shows an example of a work list 50 created by the work order determination unit 26. As shown in FIG.
The work list 50 includes work order 57, work content, required parts, estimated work time, arrangement time, work type, required number of people, parts cost, contract information 51, and past information 52 as items (fields). The "estimated work time" is the time (minutes) required from the start of the work to the completion of the work. The “arrangement time” is the time (minutes) from when the parts are arranged until the parts arrive at the worker U. "Parts cost" is the price of the parts to be replaced (for example, the unit is yen). For example, the parts cost may be the cost including the parts cost and the labor cost. "Contract information 51" is information indicating the content of the maintenance contract. The "past information 52" is past response history information, which is the time from the day of the work to the last execution of the work. Here, "time" means "a certain length of time", but "time" as a unit indicating the length of time may be used. In this embodiment, "day" is used as the unit of "time". In FIG. 5, the contract information 51 and the past information 52 are blank because they have not yet been given information.

Next, the work order determination unit 26 gives (inputs) information to each item of the contract information 51 and the past information 52 in the work list 50 (S12). FIG. 6 shows an example in which contract information (POG contract) and past correspondence history information are added to the work list 50 . For example, the contract information 51 is "P", and the contract is such that the customer is responsible for parts replacement. "P" is an abbreviation for POG contract, and full maintenance contract is written as "F". In the work list 50, "1", "30", and "60" are given to "Y1 connector voltage check", "substrate voltage check", and "AVR replacement" as past information 52, respectively.

Next, the work order determination unit 26 performs score conversion for each work using each score function (see FIGS. 8 and 12 described later) (S13). In the present embodiment, for example, as shown in FIG. 8, a score function 61 (time function T(x)) related to expected work time, a score function 62 (contract function K _P (x, y)) related to contract content, It has a score function 63 (state function J(x)). Calculation formula 64 sums the scores calculated by each score function to calculate a total score. A calculation method using each score function will be described with reference to FIG.

FIG. 7 is a flowchart showing a detailed procedure example of the score calculation process using each score function in step S13.
First, the work order determination unit 26 refers to the contract information 51 of the work list 50, and determines whether or not the customer's contract includes a charge for parts replacement (that is, an additional cost is incurred) (S21). If the content of the contract is that parts replacement is charged (YES in S21), the work order determination unit 26 selects a contract function (score function 62 in FIG. 8) that increases the score of work that does not involve parts replacement ( S22). In addition, the work order determination unit 26 determines that if the customer's contract does not include a charge for parts replacement, that is, the parts replacement is free of charge (NO in S21), the contract function (Fig. 12 is selected (S23).

Thus, the contract function is switched according to the content of the customer's maintenance contract. Then, the work order determination unit 26 calculates the score of each score function (S24), and when the calculation is completed, the process proceeds to step S14 in FIG.

FIG. 8 shows a first example (POG contract) of each score function.
FIG. 9 shows an example in which the score of each score function and the total score are assigned to the task list 50 of FIG.
The time function T(x) of the score function 61 calculates the score using the estimated work time (x) of the work list 50, and the result is entered in the item (field) of the time function 53 of the work list 50 shown in FIG. Store. For example, the time function T(x) has a score of "3" when the estimated work time is less than 30 minutes, a score of "2" when the estimated work time is 30 minutes or longer and less than 60 minutes, and a score of 60 minutes or longer. Output "1".

The contract function K _P (x, y) of the score function 62 calculates a score from the work type (x) and the part cost (y) of the work list 50, and the result is used as the contract function 54 of the work list 50 shown in FIG. stored in the items (fields) of For example, the contract function K _P (x, y) outputs a score of "3" when the work type (x) is "confirmation". Also, the contract function K _P (x, y) outputs a score of "2" when the work type (x) is "replacement" and the parts cost (y) is less than 5000 yen. Also, the contract function K _P (x, y) outputs a score of "1" when the work type (x) is "replacement" and the part cost (y) is 5000 yen or more.

As a result, when the maintenance contract indicated by the contract information 51 is a POG contract (first contract) in which additional costs are incurred when performing the target work (for example, parts replacement work), A low priority (latest order) can be assigned to the corresponding work in . The target work here is part replacement work, but is not limited to this work.

The state function J(x) of the score function 63 calculates a score from the past information 52(x) of the work list 50, and stores the result in the item (field) of the state function 55 of the work list 50 shown in FIG. . For example, the state function J(x) has a score of "1" when the number of days until the previous execution date of the target work as past information is 7 days or less, and a score of "2" when the number of days is more than 7 days and 90 days or less. ”, and output a score “3” when the same number of days exceeds 90 days.

Score functions 61 to 63 (time function T(x), contract function K _P (x, y), state function J(x)) are added each time by adding items to the work list 50 and reviewing necessary conditions. , shall be deleted.

Returning to the description of FIG. After the process of step S13, the work order determination unit 26 calculates the total score by summing the scores of the score functions for each work using the calculation formula 64 (S14), and the item of the total score 56 in the work list 50 shown in FIG. output to As shown in formula 64 in FIG. 8, the total score for the POG contract is the sum of the scores for the time function T(x), the contract function K _P (x, y), and the state function J(x). It is.

Next, the work order determination unit 26 performs work order adjustment processing based on the value of the total score of each work (S15). That is, the work order determination unit 26 determines the order in which each work in the work list 50 should be performed based on the value of the total score for each work, and outputs it to the work order 57 item of the work list 50 shown in FIG. . In the work list 50 of FIG. 9, the value of the total score 56 of the work contents "connector A - detachment confirmation", "connector B - detachment confirmation", and "printed board_fuse confirmation" of the records on the first to third rows from the top is the largest at "9". These tasks with the highest total score 56 have the highest priority and are assigned the task order of "1". That is, the work instruction device 20, as a basic idea in the case of the POG contract, instructs the execution of work starting with work that does not involve parts replacement.

On the other hand, the work content "fuse replacement" in the work list 60 has a low parts cost of 1,000 yen, a short estimated work time of 10 minutes, and no past information. The number is increased to "8", and the work order is set to "2". In addition, the work content "AVR replacement" has a high parts cost of 30,000 yen, and the past information is 60 days. It is set to the slow "4" number. In addition, the work content "printed board replacement" has a high part cost of 50,000 yen and an expected work time of 30 minutes, so the value of the total score 56 is as low as "6". is set to "4" which is the slowest.

After completing the work order adjustment process, the work order determination unit 26 proceeds to step S<b>5 in FIG. 3 , and transmits the work list 50 with the work order adjusted to the work terminal 30 . The operator U confirms this work list 50, and preferentially performs "connector A-detachment check", "connector B-detachment check", and "printed board_fuse check", which are the first work order. Since the tasks with the same work order have the same priority, when there are a plurality of tasks with the same work order, the worker U can arbitrarily determine the order of these tasks. Then, the worker U performs the work according to the work order in the work list 50, and does not perform the work after the elevator 11 recovers from the failure.

In this way, in the case of a customer who has signed a maintenance contract that requires replacement of parts for a fee, by giving priority to life-prolonging work other than equipment replacement and work based on past cases, it is possible to replace equipment as much as possible. can be prevented from occurring. The work based on past examples includes, for example, work with a short expected work time and work other than work that was not effective in the past. In addition, if it becomes necessary to replace the equipment, it is possible to smoothly explain the situation to the customer by presenting the details of the work and the additional cost to the customer.

(For full maintenance contract)
Next, a work list when the maintenance contract is a full maintenance contract will be described with reference to FIGS. 10 to 13. FIG.

FIG. 10 shows an example of a work list 60 created by the work order determination unit 26. As shown in FIG.
The contents of this work list 60 are the same as the work list 50 of FIG.

FIG. 11 shows an example in which contract information (full maintenance contract) and past response history information are added to the work list 60 .
In the work list 60, the contract information 51 of each work is given an "F" indicating a full maintenance contract in which the customer does not bear the cost of parts replacement. Further, in the work list 60, as in the work list 50, as the past information 52, "1", "30", and "1", "30", and "60" is given.

FIG. 12 shows a second example (full maintenance contract) of each score function.
The contract function K _F (x) of the score function 62A relating to contract content calculates a score based on the work type (x) of the work list 50, and the result is entered as an item (field) of the contract function 54 of the work list 60 shown in FIG. store in The part cost (y) is unused in the contract function K _F (x). For example, the contract function K _F (x) outputs a score of "1" when the work type (x) is "confirmation". Also, the contract function K _F (x) outputs a score of "3" when the work type (x) is "exchange".

As a result, if the maintenance contract indicated by the contract information 51 is a full maintenance contract (second contract) that does not incur additional costs when performing the target work, the corresponding work in the work list 60 High priority (earliest order) can be assigned. The target work here is part replacement work, but is not limited to this.

As shown in the calculation formula 64A in FIG. 12, the total score for the full maintenance contract is the sum of the scores of the time function T(x), the contract function K _F (x), and the condition function J(x). is.

FIG. 13 shows an example in which the score of each score function and the total score are given to the task list 60 of FIG.
In the work list 60 of FIG. 11, the value of the total score 56 of the work content "fuse replacement" on the eighth row from the top is "9", which is the highest. Therefore, the priority of this work is the highest, and the work order is set to "1". Next, the value of the total score 56 for the work contents "AVR replacement" and "printed board replacement" on the 9th and 10th rows from the top is "8", which is the second largest in the work list 60. FIG. Therefore, these two works have the second highest priority, and the work order is set to "2".

On the other hand, the work content "Y1 connector voltage check" in the work list 60 does not incur any parts cost, but since the past information is one day, the value of the total score 56 is as low as "4", and the work order is the slowest. It is set to number "6". In addition, although the work content "board voltage check" does not require parts cost, the expected work time is as long as 60 minutes, so the value of the total score 56 is as low as "4", and the work order is "6", which is the slowest work order. is set to

In this way, in the case of a customer who has signed a maintenance contract that includes free parts replacement, etc., priority is given to the replacement of the causative equipment in the order of work, and the elevator 11 can be restored quickly by replacing the equipment. It becomes possible to In addition, since the operator U can arrange the part (causing device) when the causative device is estimated, it is possible to reduce the time required to obtain the component.

If there is a contract form other than the POG contract (P) and the full maintenance contract (F), a new contract function is added in addition to the contract function K _P (x, y) and the contract function K _F (x). be. In addition, items (fields) are added to the work lists 50 and 60 when it is necessary to increase the number of arguments of the contract function. In other words, when the operation conditions and judgment conditions are changed in the work instruction device 20, it is possible to change the conditions of each function, add and delete other functions, and add items to the work list.

As described above, the work instruction device (work instruction device 20) according to one embodiment, when a failure occurs in the monitored object (e.g., elevator 11), the maintenance contract (e.g., POG contract) concluded with the monitored object , full-maintenance contract), based on the contract information (contract information 51) indicating the contents of the work list (work lists 50, 60) created for the failure, the priority (value of the contract function 54) , determines the order in which each work should be performed based on the priority, and outputs a work list reflecting the order (work order determination unit 26).

According to the work instruction device having the above configuration, when a failure occurs in the monitored object, it is possible to present the necessary work to the worker while minimizing price negotiations with the customer.

Further, in the above-described embodiment, the work order determination unit (work order determination unit 26) determines that the maintenance contract indicated by the contract information is the first to incur additional costs in performing the target work (for example, parts replacement work). 1 contract (for example, POG contract), a high priority is set for the work (component cost "0") that does not correspond to the above-mentioned target work in the work list (work list 50). Further, if the maintenance contract is a second contract (for example, a full maintenance contract) that does not incur additional costs in performing the target work, the work order determination unit determines that a work list (work list 60) A high priority is set for the work (parts cost generation) corresponding to the above target work in the above.

According to the work instruction device having the above configuration, depending on whether the maintenance contract is the first contract in which additional costs are incurred in performing the target work (for example, parts replacement work) or the second contract in which additional costs are not incurred , the priority set for each task in the task list can be changed, and the order of each task can be determined. This allows the on-site worker to check the work list displayed on the work terminal and easily determine the order of work to be performed.

Further, when the maintenance contract is the first contract, the work order determination unit (work order determination unit 26) according to the above-described embodiment gives lower priority ( contract function score value).

According to the work instruction device having the above configuration, it is possible to preferentially present to the worker work that does not require additional cost or work that does not require additional cost, avoiding work that requires high additional cost. This makes it easier for the customer to agree with the work content in terms of price when the worker negotiates the work content and price with the customer.

In addition to the contents of the maintenance contract, the work order determination unit (work order determination unit 26) according to the above-described embodiment determines the estimated work time required from start to completion of work and/or from the time of the day of work. Based on past response history information (past information 52) indicating the time up to the previous execution of the corresponding work, the priority of each work in the work list is set. The work order determination unit sets a higher priority for a work with a shorter estimated work time, and sets a higher priority for a work with a longer number of days of past response history information.

According to the work instruction device having the above configuration, the priority of each work is set in consideration of the expected work time and/or past response history information in addition to the content of the maintenance contract. Order of work is more optimized. By adding the expected work time to the order of work, the work time required to complete troubleshooting can be shortened. In addition, by adding past response history information to the order of work, it is possible to delay the order of work that was performed in the past but was not effective.

Furthermore, the present invention is not limited to the one embodiment described above, and it goes without saying that various other application examples and modifications can be made without departing from the gist of the present invention described in the claims. .

For example, the above-described embodiment is a detailed and specific description of the configuration of the work instruction device and the work support system in order to explain the present invention in an easy-to-understand manner. not. Moreover, it is also possible to add, delete, or replace a part of the configuration of one embodiment with another component. Further, each of the configurations, functions, processing units, etc. described above may be realized by hardware, for example, by designing a part or all of them using an integrated circuit.

Also, each component (blocks and database) of the work instruction device according to the above-described embodiment may be implemented in any device as long as each component can transmit and receive information to and from each other via a communication network. . For example, the work list creating unit 29 may be provided in a server (not shown) connected to a communication network. In this case, the server collects the status data D1 of the elevator 11, creates a work list necessary for the failure occurring in the elevator 11, and transmits the work list to the work instruction device 20. FIG. When the work instruction device 20 receives the work list for the elevator 11 from the server, it determines the order in which each work in the work list should be performed based on the contents of the maintenance contract for the elevator 11, and outputs the work list reflecting the order. do. All or part of the work list creating unit 29 may be provided in the server. Also, the management information database 27 may be provided on the server side.
