Description

[Technical Field]

[0001] The present invention relates to a working time calculation apparatus, method, and program. [Background Art]

[0002] Generally, a plurality of work orders are assigned per day for maintenance work of various devices, and workers perform work while moving between a plurality of visit locations. For this reason, a reference working time (hereinafter referred to as a standard working time) is set in advance for each work order, and the work schedule of each worker is set in consideration of this standard working time. If the standard working time is set shorter than an appropriate value, work cannot be performed according to the schedule, so work cannot be started at the time desired by the customer, which may cause inconvenience to the customer. As a result, this may lead to a decrease in customer satisfaction (CS: Customer satisfaction). On the other hand, if the standard working time is set longer than an appropriate value, unnecessary time is generated in the schedule, leading to a decrease in productivity. Therefore, the standard working time plays a very important role in performing maintenance work. As the standard working time, for example, Patent Document 1 uses the actual time of the same past work for the time required for work. [Prior Art Literature] [Patent Literature]

[0003] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2013-025771 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] The following analysis is provided by the inventor of the present application.

[0005] However, even for the same work, the working time varies depending on factors other than the work content (e.g., worker, failure, etc.), so there is room for improvement in setting an optimal standard working time.

[0006] The main objective of the present invention is to provide a work time calculation device, method, and program that can contribute to setting the optimal standard work time. [Means for solving the problem]

[0007] The work time calculation device for the first perspective includes a work time calculation unit configured to calculate the standard work time for maintenance work by referring to a database based on device data that identifies the device to be maintained, replacement parts data that identifies replacement parts, failure level data that identifies the failure level indicating the degree of reproducibility of the failure, and worker data that identifies the worker.

[0008] The second method for calculating work time includes the step of a work time calculation device calculating standard work time for maintenance work by referring to a database based on device data that identifies the device to be maintained, replacement parts data that identifies replacement parts, failure level data that identifies the failure level indicating the degree of reproducibility of the failure, and worker data that identifies the worker.

[0009] The program related to the third perspective causes the work time calculation device to perform a process of calculating the standard work time for maintenance work by referring to a database based on device data that identifies the equipment to be maintained, replacement parts data that identifies replacement parts, failure level data that identifies the failure level indicating the degree of reproducibility of the failure, and worker data that identifies the worker.

[0010] The program can be recorded on a computer-readable storage medium. The storage medium can be a non-transitory medium such as semiconductor memory, hard disk, magnetic recording medium, or optical recording medium. Furthermore, in this disclosure, it is also possible to embody the program as a computer program product. The program is input to the computer device via an input device or an external communication interface, stored in a storage device, drives the processor according to predetermined steps or processes, and can display the processing results, including intermediate states, at each stage via a display device as needed, or communicate with the outside via a communication interface. For example, the computer device for this purpose typically comprises a processor, storage device, input device, communication interface, and, if necessary, a display device, all of which are connected to each other by a bus. [Effects of the Invention]

[0011] The first to third perspectives described above can contribute to setting the optimal standard working time. [Brief explanation of the drawing]

[0013] The embodiments will be described below with reference to the drawings. In this application, reference numerals are used solely to aid understanding and are not intended to limit the invention to the illustrated embodiments. Furthermore, the embodiments described below are merely illustrative and do not limit the invention. The connecting lines between blocks in the drawings and other diagrams referenced in the following description include both bidirectional and unidirectional lines. Unidirectional arrows schematically represent the flow of the main signal (data) and do not exclude bidirectionality. In addition, although not explicitly shown, input ports and output ports exist at the input and output ends of each connecting line in the circuit diagrams, block diagrams, internal configuration diagrams, and connection diagrams disclosed in this application. The same applies to input / output interfaces. The program is executed via a computer device, which includes, for example, a processor, storage device, input device, communication interface, and, if necessary, a display device. The computer device is configured to communicate with internal or external devices (including computers) via the communication interface, whether wired or wireless.

[0014] [Form 1] A working time calculation apparatus according to Embodiment 1 will be described with reference to the drawings. FIG. 1 is a block diagram schematically illustrating a first example of the configuration of the working time calculation apparatus according to the present disclosure. FIG. 2 is a schematic diagram illustrating an example of the configuration of a reference working time database used in the working time calculation apparatus according to the present disclosure. FIG. 3 is a schematic diagram illustrating an example of the configuration of a worker database used in the working time calculation apparatus according to the present disclosure.

[0015] The working time calculation apparatus 10 is an apparatus that calculates the time required for work (see FIG. 1). As the working time calculation apparatus 10, an apparatus having a computer function, such as a server, a personal computer, or the like, can be used. By executing a stored predetermined program, the working time calculation apparatus 10 can be configured to virtually include a data acquisition unit 11, a working time calculation unit 12, a database unit 13, and a data output unit 14.

[0016] The data acquisition unit 11 is a functional unit that acquires data (see Figure 1). Examples of data to be acquired include device data, replacement parts data, failure level data, and worker data. Device data is data that identifies the device (model) to be maintained. Replacement parts data is data that identifies the replacement parts that are predicted to be the cause of the failure, based on the device to be maintained and the failure level, based on reports from the customer when a failure occurs. Failure level data is data that identifies the failure level, indicating the degree of reproducibility of the failure, such as whether the same failure has occurred in the past and how frequently it occurs. The higher the failure level, the lower the reproducibility of the failure (i.e., the more difficult the work is judged to be). Failure level data is created based on reports from the customer when a failure occurs. Worker data is data that identifies the worker performing the maintenance work, and can be any information that identifies the worker, such as the worker's name, employee number, email address, or mobile phone number. The data acquisition unit 11 may be configured to acquire various data by inputting various data through user operations, or it may be configured to acquire various data by receiving various data from an external source. The data acquisition unit 11 can output the acquired data to the work time calculation unit 12, the database unit 13, and the data output unit 14.

[0017] The work time calculation unit 12 is a functional unit that calculates the standard work time for maintenance work (see Figure 1). The work time calculation unit 12 acquires equipment data, replacement parts data, failure level data, and worker data from the data acquisition unit 11. By acquiring the equipment data, replacement parts data, failure level data, and worker data, the work time calculation unit 12 starts the process of calculating the standard work time. The work time calculation unit 12 extracts the standard work time corresponding to the acquired equipment data, replacement parts data, and failure level data from the standard work time database 13a (see Figure 2) of the database unit 13. The work time calculation unit 12 extracts the number of work experience corresponding to the acquired worker data from the worker database 13b (see Figure 3) of the database unit 13. The work time calculation unit 12 calculates the standard work time based on the extracted standard work time and the number of work experience. As an example of calculating standard work time, the work time calculation unit 12 determines whether the extracted number of work experience sessions is equal to or greater than a preset first predetermined number N1 (for example, 10 times). If the number of work experience sessions is equal to or greater than the first predetermined number N1, it can calculate the standard work time by shortening the base work time (for example, by shortening by 10 minutes), assuming that the worker has more experience and therefore the work time will be shorter. Furthermore, if the number of work experience sessions is less than the first predetermined number N1, the work time calculation unit 12 determines whether the extracted number of work experience sessions is equal to or greater than a preset second predetermined number N2 (a value less than N1; for example, 3 times). If the number of work experience sessions is equal to or greater than the second predetermined number N2, it can calculate the base work time as the standard work time. Moreover, if the number of work experience sessions is less than the second predetermined number N2, the work time calculation unit 12 can calculate the standard work time by extending the base work time (for example, by extending by 20 minutes), assuming that the worker has less experience and therefore the work time will be longer. Furthermore, the work time calculation unit 12 may calculate the standard work time not only based on the extracted standard work time and number of work experiences, but also based on the qualification information held by the worker if such qualification information is included in the worker data. For example, if qualification information is available, the standard work time can be calculated in a way that shortens the standard work time.

[0018] The database unit 13 is a functional unit that stores various databases (see FIG. 1). The database unit 13 stores a reference work time database 13a (see FIG. 2) and a worker database 13b (see FIG. 3). As shown in FIG. 2, the reference work time database 13a can be, for example, a database in which devices, replacement parts, failure levels, and reference work times are associated with each other. According to the reference work time database 13a, by specifying the device name, the replacement part name, and the failure level, it is possible to extract the reference time (reference work time) required for part replacement work. As shown in FIG. 3, the worker database 13b can be, for example, a database in which worker names (e.g., full name, employee number), contact information (e.g., email address, telephone number), and the number of work experiences are associated with each other. Although the worker database 13b describes the number of work experiences for each worker, it may also be configured to associate the number of work experiences for each device in more detail for each worker. The update of the number of work experiences will be described in Mode 2.

[0019] The data output unit 14 is a functional unit that outputs data (see FIG. 1). The data output unit 14 outputs standard work time data that is the calculation result of the work time calculation unit 12. For example, the data output unit 14 acquires the standard work time calculated by the work time calculation unit 12, and outputs it to the outside (display, transmission, etc.).

[0020] Next, the operation of the work time calculation device according to Mode 1 will be described with reference to the drawings. FIG. 4 is a flowchart schematically showing an example of the operation of the work time calculation device according to the present disclosure. Please refer to FIGS. 1 to 3 for the configuration of the work time calculation device.

[0021] First, the data acquisition unit 11 acquires device data, replacement part data, failure level data, and worker data (step A1).

[0022] Next, the work time calculation unit 12 starts the standard work time calculation process by acquiring device data, replacement parts data, failure level data, and worker data from the data acquisition unit 11, and extracts the standard work time corresponding to the acquired device data, replacement parts data, and failure level data from the standard work time database 13a (see Figure 2) of the database unit 13 (step A2).

[0023] Next, the work time calculation unit 12 extracts the number of work experiences corresponding to the acquired worker data from the worker database 13b (see Figure 3) of the database unit 13 (step A3).

[0024] Next, the work time calculation unit 12 determines whether the extracted number of work experience sessions is equal to or greater than a preset first predetermined number N1 (for example, 10 times) (step A4).

[0025] If the number of work experience sessions is 1 or more (YES in step A4), the work time calculation unit 12 calculates the standard work time by shortening the reference work time (for example, by 10 minutes) assuming that the worker's experience will result in shorter work times (step A5), and then proceeds to step A9.

[0026] If the number of work experience sessions is less than the first predetermined number N1 (NO in step A4), the work time calculation unit 12 determines whether the extracted number of work experience sessions is equal to or greater than the preset second predetermined number N2 (a value smaller than N1; for example, 3 times) (step A6).

[0027] If the number of work experience sessions is equal to or greater than the second predetermined number N2 (YES in step A6), the work time calculation unit 12 calculates the acquired reference work time as the standard work time (step A7), and then proceeds to step A9.

[0028] If the number of work experience sessions is less than the second predetermined number N2 (NO in step A6), the work time calculation unit 12 calculates the standard work time by extending the reference work time (for example, by 20 minutes) assuming that the worker's experience is low and the work time will be longer (step A8), and then proceeds to step A9.

[0029] After step A5, after step A7, or after step A8, the data output unit 14 outputs the standard work time data, which is the result of the work time calculation unit 12 (step A9), and then terminates.

[0030] According to Form 1, the standard working time is calculated based on data on the equipment to be worked on, replacement parts required for maintenance work, fault level, and worker data, thus contributing to setting the optimal standard working time. As a result, a decline in customer satisfaction and productivity can be suppressed, and work can be performed efficiently.

[0031] [Form 2] The work time calculation device according to Embodiment 2 will be described with reference to the drawings. Figure 5 is a schematic block diagram showing a second example of the configuration of the work time calculation device according to this disclosure.

[0032] Embodiment 2 is a modification of Embodiment 1, with the addition of a work experience count update unit 15. In Embodiment 2, the data acquisition unit 11 acquires work completion data (for example, data including the worker and work completion) related to the completion of work, and the work experience count update unit 15 updates the work experience count of the worker in the worker database 13b corresponding to the worker in the work completion data (adding one). Work completion data can be acquired by the user by inputting into the work time calculation device 10, or by receiving it from the worker's terminal. The work experience count is updated each time work is completed, and after a predetermined time has elapsed since the work time calculation unit 12 calculated the standard work time (or since the data output unit 14 outputted the standard work time), the work experience count update unit 15 may request work completion data from the corresponding worker's terminal (not shown) (or request the user of the work time calculation device 10 to update the work experience count). Other configurations and operations are the same as in Embodiment 1.

[0033] According to Form 2, similar to Form 1, it can contribute to setting the optimal standard work time, and it can also automatically update the number of work experiences of the worker, which affects the setting of the optimal standard work time.

[0034] [Form 3] A work time calculation device relating to Embodiment 3 will be described with reference to drawings. Figure 6 is a schematic block diagram showing a third example of the configuration of the work time calculation device relating to this disclosure. Figure 7 is a schematic diagram showing an example of the configuration of the work result database used in the work time calculation device relating to this disclosure.

[0035] Embodiment 3 is a modification of Embodiment 1, with the addition of a work time comparison unit 16 (see Figure 6). In Embodiment 3, the data acquisition unit 11 acquires work result data including equipment, replacement parts, failure level, actual work time, and worker name. The work result data can be acquired by the user by inputting into the work time calculation device 10, or by receiving it from a worker terminal used by the worker. The acquired work result data is stored in the work result database 13c of the database unit 13 (see Figure 7). The work time comparison unit 16 extracts and compares the actual work time in the work result database 13c corresponding to the equipment, replacement parts, failure level, and worker name in the work result database 13c with the latest standard work time output and stored by the work time calculation unit 12. The work time comparison unit 16 calculates the percentage of the total number of work cases for each equipment during a predetermined period (for example, one month) in which the actual work time exceeded (or fell below) the standard work time, and determines whether the calculated percentage exceeds a predetermined percentage set in advance. If the calculated ratio exceeds a predetermined ratio (i.e., there is variation depending on the worker's experience), the work time comparison unit 16 can output information regarding a review of the standard work time (review of shortened or extended time) via the data output unit 14. For example, if there are five instances where the actual work time for a task with a standard work time of 60 minutes was 90 minutes (30 minutes over), the unit can request a review of the standard work time from the department that manages the standard work time. This makes it possible to set a highly accurate standard work time that also takes actual work time into consideration. Information regarding the difference in time and the number of times the standard was exceeded, which serves as a guideline for requesting a review, may be stored in the work time comparison unit 16 or in the database unit 13. Other configurations and operations are the same as in Form 1. Furthermore, Form 3 may also be applied to Form 2.

[0036] According to Form 3, similar to Form 1, it is possible to contribute to setting an optimal standard work time, and also to set a highly accurate standard work time that takes actual work time into consideration.

[0037] [Form 4] A work time calculation device relating to Embodiment 4 will be described with reference to drawings. Figure 8 is a schematic block diagram showing a fourth example of the configuration of the work time calculation device relating to this disclosure.

[0038] Embodiment 4 is a modification of Embodiment 1, with the addition of an alarm issuing unit 17 (see Figure 8). The alarm issuing unit 17 has a timer function and issues an alarm at a predetermined time before the end of the standard work time calculated by the work time calculation unit 12 (for example, 10 minutes before the end of the standard work time). The alarm is sent to the worker's terminal 20 (for example, an information and communication terminal such as a smartphone or smartwatch). If the work is completed at the predetermined time before the end of the standard work time (for example, if the work time calculation device 10 has acquired the work completion data in Figure 5 or the work result data in Figure 6), the alarm can be disabled by operating the worker's terminal 20 (it may also be automatically disabled if work result data has been acquired). The other configurations and operations are the same as in Embodiment 1. Embodiment 4 may also be applied to Embodiments 2 and 3.

[0039] According to Form 4, similar to Form 1, it can contribute to setting an optimal standard work time, and the alarm unit 17 sends an alarm to the worker terminal 20 a predetermined time before the end of the standard work time, making it possible to remind the worker of the work time if they have not completed the work as planned. In addition, if the work is not completed a predetermined time before the end of the standard work time, it is possible to prompt the remote supporter to provide assistance.

[0040] [Form 5] A work time calculation device relating to Embodiment 5 will be described with reference to drawings. Figure 9 is a schematic block diagram showing a fifth example of the configuration of the work time calculation device relating to this disclosure.

[0041] The work time calculation device 10 is a device that calculates work time. The work time calculation device 10 includes a work time calculation unit 12. The work time calculation unit 12 is configured to calculate the standard work time for maintenance work by referring to a database 13d based on device data that identifies the device to be maintained, replacement parts data that identifies replacement parts, failure level data that identifies the failure level indicating the high reproducibility of the failure, and worker data that identifies the worker.

[0042] According to Form 5, the standard working time is calculated based on data on the equipment to be worked on, replacement parts required for maintenance work, fault level, and worker, thus contributing to setting the optimal standard working time.

[0043] The work time calculation devices according to forms 1 to 5 can be configured using so-called hardware resources (information processing devices, computers), and a configuration as illustrated in Figure 10 can be used. For example, the hardware resource 100 includes a processor 101, memory 102, network interface 103, etc., which are interconnected by an internal bus 104.

[0044] The configuration shown in Figure 10 is not intended to limit the hardware configuration of the hardware resource 100. The hardware resource 100 may include hardware not shown (e.g., input / output interfaces). Similarly, the number of units such as processors 101 included in the device is not limited to the example in Figure 10; for example, multiple processors 101 may be included in the hardware resource 100. For example, a CPU (Central Processing Unit), MPU (Micro Processor Unit), GPU (Graphics Processing Unit), etc., can be used for the processor 101.

[0045] Memory 102 can be, for example, RAM (Random Access Memory), ROM (Read Only Memory), HDD (Hard Disk Drive), SSD (Solid State Drive), etc.

[0046] The network interface 103 can use, for example, a LAN (Local Area Network) card, a network adapter, a network interface card, etc.

[0047] The functions of the hardware resource 100 are realized by the processing module described above. This processing module is realized, for example, by the processor 101 executing a program stored in memory 102. Furthermore, this program can be downloaded via a network or updated using a storage medium containing the program. Moreover, the processing module may be implemented by a semiconductor chip. In other words, the functions performed by the processing module can be realized by the execution of software on some hardware.
