Description

[Technical Field]

[0001] The present invention relates to an operation time calculation device, method, and program. [Background technology]

[0002] In the maintenance work of various equipment, multiple tasks are typically assigned per day, and workers perform their work while traveling between multiple locations. Therefore, a target work time (hereinafter referred to as "standard work time") is set in advance for each task, and each worker's work schedule is set taking this standard work time into consideration. If the standard work time is set shorter than the appropriate value, the work cannot be completed according to the schedule, and the work cannot start at the time the customer requested, which may inconvenience the customer. This may lead to a decrease in customer satisfaction (CS). On the other hand, if the standard work time is set longer than the appropriate value, unnecessary time will be added to the schedule, resulting in a decrease in productivity. Therefore, the standard work time plays a very important role in performing maintenance work. For example, in Patent Document 1, the standard work time is calculated by using the actual time spent on the same work in the past as the time required for the work.

[0003] [Patent Document 1] Patent Publication No. 2013-025771 Summary of the Invention [Problem to be solved by the invention]

[0004] The following analysis is provided by the present inventors.

[0005] However, even for the same task, the task time varies depending on factors other than the task content (for example, the worker, obstacles, etc.), so there is room for improvement in setting the optimal standard task time.

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

[0007] The work time calculation device according to the first aspect includes a work time calculation unit configured to calculate a standard work time for maintenance work by referring to a database based on device data identifying the device to be maintained, replacement part data identifying the replacement part, fault level data identifying a fault level indicating the reproducibility of the fault, and worker data identifying the worker.

[0008] The work time calculation method according to the second aspect includes a step in which a work time calculation device calculates a standard work time for maintenance work by referring to a database based on device data identifying the device to be maintained, replacement part data identifying the replacement part, fault level data identifying a fault level indicating the reproducibility of the fault, and worker data identifying the worker.

[0009] The program according to the third aspect causes the work time calculation device to execute a process of calculating a standard work time for maintenance work by referring to a database based on device data that identifies the device to be maintained, replacement part data that identifies the replacement part, fault level data that identifies the fault level indicating the reproducibility of the fault, 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 a semiconductor memory, a hard disk, a magnetic recording medium, or an optical recording medium. The present disclosure can also be embodied as a computer program product. The program is input to a computer device via an input device or a communication interface from the outside, stored in a storage device, and drives a processor according to predetermined steps or processes. The processing results, including intermediate states as needed, can be displayed at each stage on a display device, or the computer device can communicate with the outside via the communication interface. For example, a computer device for this purpose typically includes a processor, a storage device, an input device, a communication interface, and a display device as needed, all of which can be connected to each other via a bus.

[0013] The following description of the embodiments will be made with reference to the drawings. Note that, where reference numerals are used in this application, they are intended solely to facilitate understanding and are not intended to limit the present invention to the illustrated embodiments. Furthermore, the following embodiments are merely exemplary and do not limit the present invention. Furthermore, connecting lines between blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional lines. Unidirectional arrows are used to schematically indicate the flow of main signals (data) and do not exclude bidirectionality. Furthermore, although not explicitly shown, input and output ports exist at the input and output ends of each connecting line in the circuit diagrams, block diagrams, internal configuration diagrams, connection diagrams, and the like shown in this disclosure. The same applies to input and output interfaces. A program is executed via a computer device, which includes, for example, a processor, a storage device, an input device, a 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] An operation time calculation device according to a first embodiment will be described with reference to the drawings. FIG. 1 is a block diagram schematically illustrating a first example of the configuration of an operation time calculation device according to the present disclosure. FIG. 2 is a schematic diagram illustrating an example of the configuration of a standard operation time database used in the operation time calculation device according to the present disclosure. FIG. 3 is a schematic diagram illustrating an example of the configuration of a worker database used in the operation time calculation device according to the present disclosure.

[0015] The task time calculation device 10 is a device that calculates the time required for a task (see FIG. 1). A device having computer functions, such as a server or a personal computer, can be used as the task time calculation device 10. By executing a predetermined stored program, the task time calculation device 10 can virtually be configured to include a data acquisition unit 11, a task 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 FIG. 1). Examples of the acquired data include device data, replacement part data, fault level data, and worker data. The device data is data that identifies the device (model) to be maintained. The replacement part data is data that is received from a customer when a fault occurs and identifies the replacement part that is predicted to be the cause of the fault based on the device to be maintained and the fault level. The fault level data is data that identifies the fault level, which indicates the reproducibility of the fault, such as whether the same fault has occurred in the past and how frequently it occurs. The higher the fault level, the lower the reproducibility of the fault (i.e., the higher the task difficulty). The fault level data is created based on a customer's report when a fault occurs. The worker data is data that identifies the worker who will perform the maintenance work, and may 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 acquire various data by inputting various data through user operations, or by receiving various data from an external source. The data acquisition unit 11 can output the acquired various 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 a standard work time for maintenance work (see FIG. 1). The work time calculation unit 12 acquires equipment data, replacement part data, failure level data, and worker data from the data acquisition unit 11. The work time calculation unit 12 starts the calculation process of the standard work time by acquiring the equipment data, replacement part data, failure level data, and worker data. The work time calculation unit 12 extracts standard work times corresponding to the acquired equipment data, replacement part data, and failure level data from the standard work time database 13a (see FIG. 2) of the database unit 13. The work time calculation unit 12 extracts the number of work experiences corresponding to the acquired worker data from the worker database 13b (see FIG. 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 number of work experiences. As an example of calculating the standard work time, the work time calculation unit 12 determines whether the extracted number of times of work experience is equal to or greater than a predetermined first predetermined number N1 (e.g., 10 times). If the number of times of work experience is equal to or greater than the first predetermined number N1, the work time calculation unit 12 can calculate the standard work time so that the standard work time is shortened (e.g., by 10 minutes) on the assumption that the worker has more experience and the work time will be shorter. Furthermore, if the number of times of work experience is less than the first predetermined number N1, the work time calculation unit 12 determines whether the extracted number of times of work experience is equal to or greater than a predetermined second predetermined number N2 (a value smaller than N1; e.g., 3 times). If the number of times of work experience is equal to or greater than the second predetermined number N2, the work time calculation unit 12 can calculate the standard work time so that the standard work time is extended (e.g., by 20 minutes) on the assumption that the worker has less experience and the work time will be longer. If the worker data includes not only the extracted standard work time and number of work experiences but also the qualification information of the worker, the work time calculation unit 12 may calculate the standard work time based on the qualification information. For example, if the qualification information is available, the standard work time can be calculated so as to shorten 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 standard operation time database 13a (see FIG. 2) and a worker database 13b (see FIG. 3). As shown in FIG. 2, the standard operation time database 13a may be a database that associates, for example, equipment, replacement parts, failure levels, and standard operation times. The standard operation time database 13a allows for identifying equipment names, replacement part names, and failure levels, thereby extracting a standard time required for part replacement work (standard operation time). As shown in FIG. 3, the worker database 13b may be a database that associates, for example, worker names (e.g., names, employee numbers), contact information (e.g., email addresses, phone numbers), and the number of times the worker has performed work. While the worker database 13b lists the number of times the worker has performed work, it may also be more detailed, by associating the number of times the worker has performed work for each equipment with each worker. Updating the number of times the worker has performed work will be described in the second embodiment.

[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, which 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, transmit, etc.).

[0020] Next, the operation of the work time calculation device according to the first embodiment will be described with reference to the drawings. Fig. 4 is a flow chart that schematically shows 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, fault level data, and worker data (step A1).

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

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

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

[0025] If the number of times the worker has performed the task is equal to or greater than the first predetermined number N1 (YES in step A4), the task time calculation unit 12 calculates the standard task time to shorten the reference task time (for example, by 10 minutes) assuming that the worker has more experience and the task time will be shorter (step A5), and then proceeds to step A9.

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

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

[0028] If the number of times the worker has performed the task is less than the second predetermined number N2 (NO in step A6), the task time calculation unit 12 calculates the standard task time so as to extend the reference task time (for example, by 20 minutes) assuming that the worker has little experience and the task time will be long (step A8), and then proceeds to step A9.

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

[0030] According to the first aspect, the standard work time is calculated based on the data of the device to be worked on, the replacement parts required for the maintenance work, the failure level, and the worker, which contributes to setting an optimal standard work time. As a result, it is possible to prevent a decrease in customer satisfaction and productivity, and to perform work efficiently.

[0031] [Form 2] The following describes an operation time calculation device according to embodiment 2 with reference to the drawings. Fig. 5 is a block diagram schematically illustrating a second example of the configuration of an operation time calculation device according to the present disclosure.

[0032] The second embodiment is a modification of the first embodiment, and includes an experienced work count update unit 15. In the second embodiment, the data acquisition unit 11 acquires task completion data (e.g., data including the worker and the task completion) related to task completion, and the experienced work count update unit 15 updates (adds one count to) the experienced work count of the worker in the worker database 13b corresponding to the worker in the task completion data. The task completion data can be acquired by a user performing an input operation on the task time calculation device 10, or can be received and acquired from a worker terminal used by the worker. The experienced work count is updated each time a task is completed, and the experienced work count update unit 15 may request task completion data from the worker terminal (not shown) of the corresponding worker (or may request an update of the experienced work count from the user of the task time calculation device 10) after a predetermined time has elapsed since the task time calculation unit 12 calculated the standard task time (or after the data output unit 14 output the standard task time). The other configurations and operations are the same as those of the first embodiment.

[0033] According to the second aspect, as with the first aspect, it is possible to contribute to setting an optimal standard working time, and also to automatically update the number of work experiences of workers, which affects the setting of the optimal standard working time.

[0034] [Form 3] An operation time calculation device according to the third embodiment will be described with reference to the drawings. Fig. 6 is a block diagram showing a schematic diagram of a third example of the configuration of an operation time calculation device according to the present disclosure. Fig. 7 is a schematic diagram showing an example of the configuration of an operation result database used in the operation time calculation device according to the present disclosure.

[0035] The third embodiment is a modification of the first embodiment, and includes an operation time comparison unit 16 (see FIG. 6). In the third embodiment, the data acquisition unit 11 acquires operation result data including the device, replacement part, failure level, actual operation time, and worker name. The user can acquire the operation result data by inputting information into the operation time calculation device 10, or the data can be received and acquired from a worker terminal used by the worker. The acquired operation result data is stored in the operation result database 13c of the database unit 13 (see FIG. 7). The operation time comparison unit 16 extracts and compares the actual operation time in the operation result database 13c corresponding to the device, replacement part, failure level, and worker name in the operation result database 13c with the latest standard operation time output and stored by the operation time calculation unit 12. The operation time comparison unit 16 calculates the proportion of the number of operations in which the actual operation time exceeded (or fell short of) the standard operation time out of the total number of operations for each device in a predetermined period (e.g., one month), and determines whether the calculated proportion exceeds a predetermined proportion. If the calculated ratio exceeds a predetermined ratio (if there is variation depending on the worker's number of experiences), the work time comparison unit 16 can output information regarding a review of the standard work time (review of the shortened or extended time) via the data output unit 14. For example, if there are five cases where the actual work time exceeds 30 minutes, exceeding the standard work time of 60 minutes by 90 minutes, a request can be made to the department that manages the standard work time to review the standard work time. This allows for setting a highly accurate standard work time that takes actual work time into consideration. Information regarding the difference in time and the number of times the time has exceeded the standard work time, which serves as a guide for the review request, can be stored in the work time comparison unit 16 or in the database unit 13. Other configurations and operations are the same as those of the first embodiment. Furthermore, the third embodiment may be applied to the second embodiment.

[0036] According to the third embodiment, similar to the first embodiment, it is possible to contribute to setting an optimal standard work time, and also to set a highly accurate standard work time that takes into account actual work time.

[0037] [Form 4] An operation time calculation device according to form 4 will be described with reference to the drawings. Fig. 8 is a block diagram schematically showing a fourth example of the configuration of an operation time calculation device according to the present disclosure.

[0038] The fourth embodiment is a modification of the first embodiment, and includes an additional alarm unit 17 (see FIG. 8). The alarm unit 17 has a timer function and issues an alarm 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 a worker terminal 20 (for example, an information communication terminal such as a smartphone or smartwatch) used by the worker. If the work has been completed before the predetermined time (for example, if the work time calculation device 10 has acquired the work completion data of FIG. 5 or the work result data of FIG. 6), the worker can disable the alarm by operating the worker terminal 20 (or automatically disable the alarm when the work result data has been acquired). The other configurations and operations are the same as those of the first embodiment. The fourth embodiment may also be applied to the second and third embodiments.

[0039] According to the fourth embodiment, similar to the first embodiment, it is possible to contribute to setting an optimal standard work time, and since the alarm issuing unit 17 issues an alarm to the worker terminal 20 at a predetermined time before the end of the standard work time, it is possible to make the worker aware of the work time again if the worker has not been able to work as planned. Also, if the work has not been completed at a predetermined time before the end of the standard work time, it is possible to prompt the remote supporter to provide support.

[0040] [Form 5] An operation time calculation device according to form 5 will be described with reference to the drawings. Fig. 9 is a block diagram schematically showing a fifth example of the configuration of an operation time calculation device according to the present disclosure.

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

[0042] According to the fifth aspect, the standard work time is calculated based on the data of the device to be worked on, the replacement parts required for the maintenance work, the failure level, and the worker, which can contribute to setting the optimal standard work time.

[0043] The task time calculation device according to the first to fifth aspects can be configured using so-called hardware resources (information processing devices, computers), and can use a device having the configuration shown in Fig. 10. For example, the hardware resource 100 includes a processor 101, a memory 102, a network interface 103, and the like, which are interconnected by an internal bus 104.

[0044] 10 is not intended to limit the hardware configuration of the hardware resource 100. The hardware resource 100 may include hardware (e.g., an input / output interface) that is not shown. Furthermore, the number of units such as the processor 101 included in the device is not intended to be limited to the example shown in FIG. 10, and for example, multiple processors 101 may be included in the hardware resource 100. The processor 101 may be, for example, a central processing unit (CPU), a microprocessor unit (MPU), a graphics processing unit (GPU), or the like.

[0045] The memory 102 may be, for example, a random access memory (RAM), a read only memory (ROM), a hard disk drive (HDD), or a solid state drive (SSD).

[0046] The network interface 103 may be, for example, a LAN (Local Area Network) card, a network adapter, a network interface card, or the like.

[0047] The functions of the hardware resource 100 are realized by the processing modules described above. The processing modules are realized, for example, by the processor 101 executing a program stored in the memory 102. The programs can be updated by downloading them over a network or by using a storage medium that stores the programs. Furthermore, the processing modules may be realized by semiconductor chips. In other words, it is sufficient that the functions performed by the processing modules be realized by software being executed on some kind of hardware.
