Description

The present invention relates to a work instruction device and a work instruction method for instructing an operator of necessary work.

Currently, when a failure occurs and failure recovery 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, the cost incurred by the above recovery method may not be tolerated, and there may be cases where sufficient working time cannot be obtained. In addition, local workers had to select the necessary work and adjust the price and time.

On the other hand, a technology has been proposed that enables the customer to determine the necessity of this work by calculating the maintenance fee based on the information obtained from the elevator and submitting the information to the customer. There is. For example, in Patent Document 1, "Since the customer makes a maintenance request after considering the content of the preventive maintenance information sent from the maintenance fee calculation center 9 at any time, this maintenance fee may correspond to the guarantee desired by the customer. It can be done. "

JP-A-2002-197215 (see paragraph [0024], FIG. 4, etc.)

However, since local workers have different experience points and skills, the selection of required work and the result of price and time adjustment differed depending on the local worker.

Further, in the technique described in Patent Document 1, it is necessary to determine the work content by the customer's judgment based on the necessary work based on the preventive maintenance information and the cost associated therewith. However, when dealing with a sudden failure, 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, and perform the recovery work. Furthermore, since preventive maintenance information cannot be used to deal with sudden failures, local workers need to work within the range that can be approved by the customer while negotiating prices with the customer.

From the above situation, when a failure occurs in the monitored object, a method that can present necessary work to the worker without causing price negotiation with the customer as much as possible has been desired.

In order to solve the above problems, the work instruction device of one aspect of the present invention is a work instruction device that instructs work for a failure that occurs in the monitoring target, and is the content of a maintenance contract concluded with the monitoring target. Based on the contract information indicating, the priority is set for each work in the work list created for the failure, the order in which each work should be performed is determined based on the priority, and the work in which the order is reflected is determined. It is equipped with a work order determination unit that outputs a list.

According to at least one aspect of the present invention, when a failure occurs in the monitored object, price negotiation with the customer can be minimized and necessary work can be presented to the worker.

Hereinafter, examples of embodiments for carrying out the present invention (hereinafter, referred to as “embodiments”) will be described with reference to the accompanying drawings. In the present specification and the accompanying drawings, components having substantially the same function or configuration are designated by the same reference numerals, and duplicate description will be omitted.

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

FIG. 1 is a schematic view showing an overall configuration example of a work support system 1 including a work instruction device 20 according to an 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 on-site 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 D1 including information about 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 is, for example, an output value of a sensor installed in the elevator 11.

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

The work terminal 30 is a terminal used by the worker U for work such as inspection and repair, and displays (instructs) the contents of the work transmitted from the work instruction device 20 to the worker U. 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 occurs 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 cause 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 is provided. In FIG. 2, each database is described as "DB".

The data management unit 21 receives the state data D1 about the elevator 11 transmitted from the monitoring device 12 when the elevator 11 fails, and manages the collected state 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 as a new case (case) to the past case estimation unit 22 and the cause device estimation unit 23.

The past case estimation unit 22 estimates similar past cases with reference to the past information database 25 based on the state data D1 input from the data management unit 21, and outputs the estimation result to the work order determination unit 26. .. Similar cases in the past are, for example, cases that are considered to be the same failure. Here, information such as the name and management number of the corresponding case is specified.
The cause device estimation unit 23 refers to the past information database 25 based on the state data D1 input from the data management unit 21, and causes the elevator 11 to be in the state indicated by the state data (that is, a failure). The device is estimated from the information related to the past cases, and the estimation result is output to the work extraction unit 24.
In the past information database 25, information on past cases is recorded 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 execution work), and the like. Further, the past information database 25 stores the state data collected for each case and the time required for the work.

The work extraction unit 24 extracts the work required for the cause device estimated by the cause device estimation unit 23 from the work master database 28, and outputs the extraction result (work list) to the work order determination unit 26.
Work information is registered in the work master database 28 for each cause. For example, the work master database 28 records the causative device and the work on the causative device in association with each other.

The work order determination unit 26 sets a priority for each work in the work list extracted by the work extraction unit 24 based on the contract information indicating the contents 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 executed based on the priority of each work, and outputs the work list reflecting the order. As described above, in the present embodiment, the content of the customer's maintenance contract is used as a factor for determining the work order. The 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 contents of the contract that the maintenance company of the elevator 11 has concluded with the customer regarding maintenance is recorded. For example, the types of maintenance contracts can be broadly classified into contracts in which additional costs are incurred in carrying out the target work (first contract) and contracts in which no additional costs are incurred (second contract). An example of the first contract is a POG (Parts Oil Grease) contract in which replacement of the causative device is charged. Generally, in a POG contract, periodic inspections and replacement of consumables within the control specifications are included in the cost, but replacement and repair of other consumables and parts require additional costs. An example of the second contract is a full maintenance contract in which the 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 there is no additional cost for these operations.

[Work terminal]
The work terminal 30 includes a work order 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. The work order output unit 31 may output the work order by voice instead of displaying it. After the failure response is completed, the worker U inputs the content (work record) of the work performed for the failure of the elevator 11 into 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 with respect to the failure of the elevator 11 in the past information database 25. ..

In the present embodiment, the elevator 11 is illustrated as a monitoring target, but various facilities and systems such as an escalator and equipment constituting a plant system can be monitored.

[Computer hardware configuration]
Next, the hardware configuration of the device constituting the work support system 1 and the computer constituting the terminal will be described.
FIG. 2 is a block diagram showing a hardware configuration example of the computer 40. The hardware of the work instruction device 20 and the work terminal 30 is configured by the computer 40 shown in FIG. 2, respectively. The monitoring device 12 is also composed of 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 connected to the bus, respectively. Further, the computer 40 includes a display device 44, an operating device 45, a non-volatile storage 46, and a communication interface 47.

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

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

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 and the like are used. Be done. In this non-volatile storage 46, in addition to the OS (Operating System) and various parameters, a program for operating the computer 40 is recorded. The ROM 42 and the non-volatile storage 46 can permanently record programs, data, and the like necessary for the CPU 41 to operate.

In the work instruction device 20, a program for the work instruction device 20 to operate as an application server for providing work instructions is stored in the non-volatile storage 46. Further, in the work terminal 30, a program for the work terminal 30 to operate as a client terminal for displaying a work instruction is stored in the non-volatile storage 46.

For example, a NIC (Network Interface Card), a modem, or the like is used as the communication interface 47, and various data are transmitted and received to and from an external device via a communication network such as a LAN to which terminals are connected or a dedicated line. It is configured to be possible. Further, 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.

[Process flow by work order determination unit]
The flow of processing by the work order determination unit 26 will be described with reference to FIGS. 3 to 4.
FIG. 3 is a flowchart showing the flow of processing by the work order determination unit 26.

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, the work order determination unit 26 acquires the correspondence history (for example, the date when the previous target work was performed) from the past information database 25 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 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 the work in the work list presented to the work terminal 30, and performs the work of the elevator 11 on site. The worker U inputs the actual work contents (work results) to the work terminal 30 by the operation device 45. 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 record information can be used in the event of a failure from the next time onward.

[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. FIG. 4 will be described with reference to FIGS. 5 to 13. 5 to 6 and 8 to 9 are examples of a POG contract, and FIGS. 10 to 13 are examples of a full maintenance contract.

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 information on the work contents extracted by the work extraction unit 24 and the estimated work time and the arrangement time calculated from the estimation results of the past case estimation unit 22.

(In the case of POG contract)
FIG. 5 shows an example of a work list 50 created by the work order determination unit 26.
The work list 50 includes work order 57, work contents, necessary 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 the arrangement of the parts to the delivery of the parts to the worker U. The "part cost" is the price of the part to be replaced (for example, the unit is yen). For example, the parts cost may be the cost including the work cost in the parts cost. “Contract information 51” is information indicating the contents of the maintenance contract. The "past information 52" is past correspondence history information, which is the time from the time on the day of the work to the time when the corresponding work was last performed. Here, "time" means "time having a certain length", but it may be "time" as a unit indicating the length of time. In this embodiment, "day" is used as a unit of "time". In FIG. 5, the contract information 51 and the past information 52 are left blank because they have not been given information yet.

Next, the work order determination unit 26 adds (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. The contract information 51 is set to "P" as an example, and the contract is such that the replacement of parts is borne by the customer. "P" is an abbreviation for POG contract, and is written as "F" in the case of a full maintenance contract. In the work list 50, "1", "30", and "60" are assigned to "Y1 connector voltage check", "board voltage check", and "AVR exchange" 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, the score function 61 (time function T (x)) relating to the estimated work time, the score function 62 relating to the contract content (contract function K _P (x, y)), and the past information. A score function 63 (state function J (x)) is provided. In the calculation formula 64, the total score is calculated by summing the scores calculated by each score function. The 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 content is paid for parts replacement (that is, additional cost is incurred) (S21). The work order determination unit 26 selects a contract function (score function 62 in FIG. 8) that increases the score of work in which parts replacement does not occur when the contract content is paid for parts replacement (YES in S21) (YES in S21). S22). Further, the work order determination unit 26 has a contract function (FIG. 12) in which the score of the work in which the parts replacement occurs increases when the customer's contract content is not paid for parts replacement, that is, free of charge (NO in S21). Score function 62A) of (S23).

In this way, the contract function is switched according to the contents 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, proceeds to step S14 of 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 given to the work list 50 of FIG.
The time function T (x) of the score function 61 calculates a score using the estimated work time (x) of the work list 50, and the result is displayed 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 same time is 30 minutes or more and less than 60 minutes, and a score when the same time is 60 minutes or more. Output "1".

The contract function K _P (x, y) of the score function 62 calculates a score based on the work type (x) and the part cost (y) of the work list 50, and the result is obtained by the contract function 54 of the work list 50 shown in FIG. Store in the item (field) of. For example, the contract function K _P (x, y) outputs a score “3” when the work type (x) is “confirmation”. Further, the contract function K _P (x, y) outputs a score “2” when the work type (x) is “replacement” and the part cost (y) is less than 5,000 yen. Further, the contract function K _P (x, y) outputs a score "1" when the work type (x) is "replacement" and the part cost (y) is 5000 yen or more.

As a result, if the maintenance contract shown in the contract information 51 is a POG contract (first contract) in which an additional cost is incurred when carrying out the target work (for example, parts replacement work), the work list 50 is included. It is possible to assign a low priority (latest order) to the corresponding work of. The target work here is a parts replacement work, but is not limited to this work.

The state function J (x) of the score function 63 calculates the 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 work is performed 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. ", When the number of days exceeds 90 days, the score" 3 "is output.

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 in the work list 50 and reviewing necessary conditions. , Should be deleted.

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

Next, the work order determination unit 26 performs the work order adjustment process 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 item of the work order 57 in the work list 50 shown in FIG. .. In the work list 50 of FIG. 9, the total score 56 of the work contents "connector A-attachment / detachment confirmation", "connector B-attachment / detachment confirmation", and "printed board_fuse confirmation" of the records in the first to third rows from the top Is the largest with "9". The value of the total score 56 is the highest, and the priority of these works is the highest, and the work order is set to "1". That is, as a basic idea in the case of a POG contract, the work instruction device 20 instructs the execution from the work in which the parts replacement does not occur.

On the other hand, the work content "fuse replacement" in the work list 60 has a total score of 56 because the parts cost is as low as 1000 yen, the estimated work time is as short as 10 minutes, and there is no past information. It becomes as high as "8" and the work order is set to "2". In addition, the work content "AVR replacement" has an expensive parts cost of 30,000 yen, and since the past information is 60 days, the value of the total score 56 is as low as "6", and the work order is the best. It is set to the slow "4" number. In addition, the work content "printed circuit board replacement" has a high component cost of 50,000 yen and an estimated work time of 30 minutes, so that the total score 56 is as low as "6", and the work order. Is set to the slowest number "4".

Then, after the work order adjustment process is completed, the work order determination unit 26 proceeds to step S5 of FIG. 3 and transmits the work list 50 for which the work order has been adjusted to the work terminal 30. Worker U confirms this work list 50, and preferentially carries out "connector A-attachment / detachment confirmation", "connector B-attachment / detachment confirmation", and "printed board_fuse confirmation" in which the work order is No. 1. Since the works having the same work order have the same priority, the worker U can arbitrarily determine the order of these works when there are a plurality of works having the same work order. Then, the worker U carries out the work according to the work order in the work list 50, and does not carry out the subsequent work when the elevator 11 recovers from the failure.

In this way, in the case of a customer who has a maintenance contract for which parts replacement is charged, by giving priority to work for life extension measures other than equipment replacement and work based on past cases, equipment replacement is possible. Can be prevented from occurring. The work based on the past case is, for example, a work having a short estimated work time or a work other than the work that was not effective in the past. In addition, if it becomes necessary to replace the equipment, the work contents and additional costs can be presented to the customer, and the circumstances can be smoothly explained 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. 10 shows an example of a work list 60 created by the work order determination unit 26.
The contents of the work list 60 are the same as those of the work list 50 of FIG.

FIG. 11 shows an example in which contract information (full maintenance contract) and past correspondence history information are added to the work list 60.
In the work list 60, "F" indicating a full maintenance contract that does not burden the customer when replacing parts is given to the contract information 51 of each work. Further, in the work list 60, as in the work list 50, as past information 52, “1”, “30”, and “1”, “30”, and “AVR replacement” are used for “Y1 connector voltage check”, “board voltage check”, and “AVR replacement”, respectively. "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 regarding the contract contents calculates the score according to the work type (x) of the work list 50, and the result is the item (field) of the contract function 54 of the work list 60 shown in FIG. Store in. In the contract function K _F (x), the component cost (y) is unused. For example, the contract function K _F (x) outputs a score “1” when the work type (x) is “confirmation”. Further, the contract function K _F (x) outputs a score “3” when the work type (x) is “exchange”.

As a result, when the maintenance contract shown in the contract information 51 is a full maintenance contract (second contract) in which no additional cost is incurred in carrying out the target work, the corresponding work in the work list 60 is subjected to. Higher priority (earlier order) can be assigned. The target work here is, but is not limited to, parts replacement work.

As shown in the formula 64A in FIG. 12, the total score in the case of a full maintenance contract is the sum of the scores of the time function T (x), the contract function K _F (x), and the state 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 work 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” in the eighth stage from the top is the largest as “9”. 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 of the work contents "AVR exchange" and "printed circuit board exchange" in the 9th and 10th stages from the top is "8", which is the second largest in the work list 60. Therefore, these two operations 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 require a component 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 "6". In addition, although the work content "board voltage check" does not require component costs, the estimated work time is as long as 60 minutes, so the total score 56 value is as low as "4", and the work order is the slowest "6". Is set to.

In this way, in the case of a customer who has concluded a maintenance contract that includes free parts replacement, etc., the replacement work of the causative equipment shall be prioritized as the work order, and the elevator 11 may be restored early by equipment replacement. It becomes possible to do. Further, since the worker U can arrange the parts (cause equipment) when the cause equipment is estimated, it is possible to reduce the time until the parts are obtained.

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).} The contract. If it is necessary to increase the arguments of the contract function, items (fields) are added to the work lists 50 and 60. That is, when the operation condition or the determination condition is changed in the work instruction device 20, the condition of each function can be changed, another function can be added or deleted, and the item of the work list can be added.

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

According to the work instruction device having the above configuration, when a failure occurs in the monitored object, price negotiation with the customer can be minimized and necessary work can be presented to the worker.

Further, in the above-described embodiment, in the work order determination unit (work order determination unit 26), the maintenance contract indicated by the contract information incurs an additional cost in carrying out the target work (for example, parts replacement work). In the case of 1 contract (for example, POG contract), a high priority is set for the work (part cost “0”) that does not correspond to the above target work in the work list (work list 50). In addition, when the maintenance contract is a second contract (for example, a full maintenance contract) in which no additional cost is incurred in carrying out the target work, the work order determination unit determines the work list (work list 60). Set a high priority for the work (parts cost incurred) that corresponds to the above-mentioned target work.

According to the work instruction device having the above configuration, the maintenance contract depends on whether the maintenance contract is a first contract in which an additional cost is incurred in carrying out the target work (for example, a parts replacement work) or a second contract in which no additional cost is incurred. , The priority set for each work in the work list can be changed, and the order of each work can be determined. As a result, the worker at the site can easily determine the order of the work to be performed by checking the work list displayed on the work terminal.

Further, in the work order determination unit (work order determination unit 26) according to the above-described embodiment, when the maintenance contract is the first contract, the higher the additional cost (value of the parts cost), the lower the priority (the work order determination unit 26). It is configured to set the score value of the contract function).

According to the work instruction device having the above configuration, it is possible to avoid the work with high additional cost and preferentially present the work with no additional cost or the work with low additional cost to the worker. This makes it easier for the customer to be convinced of the work content in terms of price when the worker negotiates the work content and price with the customer.

Further, the work order determination unit (work order determination unit 26) according to the above-described embodiment, in addition to the contents of the maintenance contract, the estimated work time required from the start to the completion of the work and / or from the time of the work day. It is configured to set the priority of each work in the work list based on the past correspondence history information (past information 52) indicating the time until the corresponding work is executed last time. The work order determination unit sets a higher priority for a work having a shorter expected work time, and sets a higher priority for a work with a longer number of days of past correspondence history information.

According to the work instruction device having the above configuration, the priority of each work is set in consideration of the estimated work time and / or the past correspondence history information in addition to the contents of the maintenance contract. The order of work is more optimized. By adding the estimated work time to the work order, the work time required to complete the failure response can be shortened. Further, by adding the past correspondence history information to the work order, it is possible to delay the order of the work performed in the past but not effective.

Furthermore, the present invention is not limited to the above-described embodiment, and it goes without saying that various other application examples and modifications can be taken as long as the gist of the present invention described in the claims is not deviated. ..

For example, the above-described embodiment describes in detail and concretely the configurations of the work instruction device and the work support system in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to those including all the components described above. Not done. It is also possible to add, delete, or replace other components with respect to a part of the configuration of one embodiment. Further, each of the above configurations, functions, processing units and the like may be realized by hardware by designing a part or all of them by, for example, an integrated circuit.

Further, each component (block or database) of the work instruction device according to the above-described embodiment may be mounted on any device as long as each component can send and receive information to and from each other via a communication network. .. For example, the work list creation unit 29 may be provided on a server (not shown) connected to a communication network. In this case, the server collects the state 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. When the work instruction device 20 receives the work list for the elevator 11 from the server, the work instruction device 20 determines the order in which each work in the work list should be performed based on the contents of the maintenance contract of the elevator 11, and outputs the work list reflecting the order. To do. Note that all or part of the work list creation unit 29 may be provided on the server. Further, the management information database 27 may be provided on the server side.
