FIG. 1 shows a configuration example of the entire system including the educational content creation system according to the embodiment.

At the site 151 where the worker 51 performs the work, the product 49 is manufactured by using the machine 50 provided in the manufacturing system (not shown). In the present embodiment, the "product" is not limited to a so-called finished product as a manufactured product, but means a general product to be put into a manufacturing system. Therefore, the "product" may be an item before being put into the manufacturing system, an item in the middle of the manufacturing system (so-called "semi-finished product"), or a finished product that is ready for shipment. Further, for the sake of simplicity of explanation, the manufacturing system includes one machine 50, but a plurality of machines 50 of the same or different types may be provided in the manufacturing system.

Further, at the site 151, a camera 30 for photographing the work being carried out is provided. The camera 30 creates, for example, shooting moving image data of the work performed by the worker 51 (for example, the workers 51 and 51B).

Data obtained by equipment such as the machine 50 and the camera 30 is transmitted from the equipment to the educational content creation system 101 via a network (for example, the Internet) (for example, not shown) through a gateway (not shown) provided at the site 151, for example. ..

Further, at the site 151 (or outside the site 151), there is an information processing terminal 40 (for example, a computer such as a laptop personal computer) used by the trained worker 51C. The educational UI (User Interface) 131 is displayed on the information processing terminal 40. The educational UI 131 is a UI (for example, a GUI (Graphical User Interface)) that displays at least a part of the information included in the educational program described later. The educational UI 131 illustrated in FIG. 1 displays a video of a high-level worker (for example, a so-called expert) and a video of the worker 51C side by side, and displays chips (an example of knowledge) for the worker 51C. ..

The educational content creation system 101 communicates via the above-mentioned network (not shown). As an example of the communication partner, there is a management terminal 160. The management terminal 160 is an information processing terminal of an administrator (for example, an administrator of a manufacturing system). The educational content creation system 101 transmits, for example, information (and other information) regarding the created educational content to the management terminal 160.

The educational content creation system 101 is a computer system composed of one or more physical computers, but may be a system realized based on a plurality of types of computer resources (for example, a cloud platform) possessed by the computer system. The educational content creation system 101 includes an interface device 111, a storage device 112, and a processor 113 connected to them.

Data is received from the site 151 and communicated with the management terminal 160 through the interface device 111.

The storage device 112 stores a computer program group (one or more computer programs) and information 121 to 130 described later.

The information management unit 141 and the content creation unit 142 are realized by the processor 113 executing the computer program group. In the present embodiment, the program creation unit 143 and the information provision unit 144 are further realized. In the present embodiment, since the educational content creation system 101 has the information providing unit 144, the educational content creation system 101 may be referred to as a worker education system. The information management unit 141 manages at least a part of the information 121-130. The content creation unit 142 creates educational content. The program creation unit 143 creates an educational program. The information providing department 144 provides an educational program.

Information 121-130 is, for example, as follows.

The field data group 121 is a data group of data received from the field 151, for example, periodically or sequentially. The field data group 121 includes, for example, moving image data taken by the camera 30 and data obtained by the machine 50. In other words, in this embodiment, the source of the data relating to Man is the camera 30, and the source of the data relating to Machine is the machine 50. As data regarding at least one of Man and Machine, in addition to the data collected at the site 151, there is data input from a device that manages at least one of Man and Machine (for example, management terminal 160). May be good. Further, the site data group 121 includes video management data (for example, for each shot video data, the file name of the shot video data, the shooting start time, the shooting end time, the ID of the shooting camera, and the area to which the camera belongs. Data associated with data such as an ID) may be included. Further, the site data group 121 includes worker management data (for example, for each worker 51, the ID of the worker 51, the ID of the area where the worker 51 is located, and the time when the worker 51 exists in the area. Data with which the data is associated) may be included. Which of the worker 51's shot video data is the shot video data is determined by, for example, in place of or in addition to the analysis of the shot video data, based on the video management data and the worker management data, the information management unit. It may be specified by 141.

The machine performance data group 122 is a data group (for example, a table) acquired based on the analysis result of the field data group 121 (for example, data obtained by the machine 50 in particular), and is an operation record of the machine 50 (machine 50). It is a data group representing the state and the time of the state. Specifically, for example, as illustrated in FIG. 2, the machine performance data group 122 includes information representing an operating state, a start time, a power supply state, and a rotation state. The combination of the operating state, the power supply state, and the rotating state is an example of the state of the machine 50. The time from the start time to the next start time corresponds to the time interval. The time interval is the time during which the combination of the operating state, the power supply state, and the rotating state continues without change. The machine 50 is an example of an element (non-worker) belonging to at least one of 4M (Man, Machine, Material and Method) other than Man. The machine performance data group 122 is an example of non-worker performance information.

The worker record data group 123 is a data group acquired based on the analysis result of the site data group 121 (for example, the photographed moving image data obtained by the camera 30), and the work record (work) of each worker 51. It is a data group representing the state of the person 51 and the time of the state). Specifically, for example, as illustrated in FIG. 3, the worker actual data group 123 has the worker actual data 300 for each worker 51. The worker record data 300 includes information indicating a start time and a work state. The working state is an example of the state of the worker 51. The time from the start time to the next start time corresponds to the time interval. The time interval is the time during which the working state has not changed. The worker 51 is an element belonging to Man in 4M (Man, Machine, Material and Method). The worker record data group 123 is an example of the worker record information.

The combination data group 124 is a data group based on the combination of the machine performance data group 122 and the worker performance data group 123. Specifically, for example, as illustrated in FIG. 4, the combination data group 124 has the combination data 400 for each worker 51. The combination data 400 is data based on the combination of the machine performance data group 122 and the worker performance data 300. The combination data 400 represents an operating state, a start time (start time between the times), a power supply state, a rotation state, a working state, and procedure details for each time interval. The information representing the machine state (in this embodiment, the operating state, the power supply state, and the rotating state) is the information obtained from the machine performance data group 122. The information representing the worker state (in the present embodiment, the work state) is the information obtained from the worker record data 300. The start time exists for each combination of the machine state and the worker state. When at least a part of the combination of machine state and worker state changes, so does the start time. The procedure details are part of the work details of the work performed and are identified based on the combination of the machine state and the worker state (here, including the video footage data used to identify the worker state). Details of the procedure. The procedure details include the procedure and the number of implementations for each step constituting the procedure. By having both the mechanical state and the working state for the same time period, it is possible to accurately specify the procedure details. For example, according to the columns 401A and 401B, since the machine state is the same but the worker state is different, the procedure details can be accurately specified for each time interval. On the other hand, according to the columns 401B and 401C, since the worker state is the same but the machine state is different, the procedure details can be accurately specified for each time interval.

The reference data group 125 is a data group representing a standard of work details. Specifically, for example, as illustrated in FIG. 5, the reference data group 125 represents a reference time, a reference procedure, and a reference number of times for each set of working state and product type. The reference time is an appropriate time required for work (threshold value of required time). The reference procedure is the correct procedure. The reference number of times is the correct number of times for each step constituting the reference procedure. According to the example shown in FIG. 5, the reference procedure “a-> b” means that the step “b” is performed after the step “a”, and the reference number of times “(a, b) = (2, b). 2) ”means that step“ a ”is performed twice and step“ b ”is performed twice.

The teacher data group 126 is a data group of teacher data for specifying a working state based on the captured moving image data. Specifically, for example, as illustrated in FIG. 6, the teacher data group 126 includes one or more frames constituting the moving image data representing the work state as the teacher data for each work state. The one or more frames may include, for example, a wire frame.

The worker data group 127 represents the work details of each worker 51. Specifically, for example, as illustrated in FIG. 7, the worker data group 127 includes the worker data 700 of each worker 51. The worker data 700 represents the ID of the worker 51 and the specified work details of the worker. The work details include the type of the product to be worked, the work state, the time interval (start time-end time), the required time, the implementation procedure, and the number of implementations.

The educational content group 128 is one or more educational contents. Specifically, for example, as illustrated in FIG. 8, the educational content 800 is digital content, and all (or a part) of the worker data 700 of the worker 51 determined to be high level and the work concerned. Information representing the reference time of the required time in the work details represented by the worker data 700 (reference time specified from the reference data group 125) and the time interval (work) included in the work details among the captured video data of the worker 51. The video data part corresponding to the implementation time zone) is included. Of the educational content 800, information that should not be disclosed for high-level workers (for example, the worker ID or the worker's face represented by the video data portion) is not included in the educational content 800. Alternatively, it may be displayed in a masked state on the educational UI 131.

The knowledge data group 129 is an educational knowledge data group (for example, a database). Knowledge data exists for each educational knowledge. An example of educational knowledge is chips. The knowledge data group 129 represents, for example, educational knowledge for each educational target item. Here, the "education target item" is an item having a large difference (for example, the difference exceeds the threshold value) in the comparison between the specified work details and the standard of the work details. For example, the plurality of knowledge represented by the knowledge data group 129 is the knowledge associated with a large difference between the required time and the reference time, and the knowledge associated with the mismatch between the implementation procedure and the reference procedure. , Knowledge associated with a large difference between the number of implementations and the reference number of times for each step constituting the reference procedure may be included.

The educational program group 130 is one or more educational programs. Specifically, for example, as illustrated in FIG. 9, the educational program 900 is data, and includes educational content 800, an educator's worker data 700, an educator's video data portion 910, and knowledge. Includes data 950 and. The “educated person” is a worker 51 to whom the education program 900 is provided, and is, for example, a low-level worker who is determined to have a large difference between the specified work details and the standard of the work details. .. The educational content 800 corresponds to a work state included in the identified work details of the educated person. The video data portion 910 of the educator is a portion of the video data taken by the educator that corresponds to the time period represented by the worker data 700 of the educator. The knowledge data 950 is knowledge data corresponding to an educational target item (an item having a particularly large difference among the differences between the specified work details of the educated person and the standard of the work details) in the knowledge data group 129.

The processes performed in this embodiment include an educational content creation process, an educational program creation process, an education provision process, and a management notification process. Hereinafter, each process will be described.

<Educational content creation process>

FIG. 10 shows an example of the flow of the educational content creation process. The educational content creation process is performed periodically, for example.

In S1001, the information management unit 141 acquires the machine performance data group 122 and the worker performance data group 123 by analyzing the site data group 121. For example, in the machine performance data group 122, the operating state, the power supply state, and the rotating state for each time interval are the states specified based on the data obtained from the machine 50. Further, for example, in the worker actual data group 123, for each worker 51, the work state for each time interval is based on the teacher data group 126 and the captured video data of the worker 51 (for example, motion capture is used). This is the specified state (based on the time-series wire frame of the worker 51) obtained in the above steps. The information management unit 141 distinguishes the change in the working state, and sets the start time of the change in the working state as the start time.

In S1002, the information management unit 141 identifies the work details between the times for each worker 51 by performing the aggregation for each time based on the machine actual data group 122 and the worker actual data group 123. Worker data 700 representing the specified work details is created. For example, S1002 includes the following S1002-1 to S1002-3.
(S1002-1) The information management unit 141 creates combination data 400 for each worker 51 from the machine performance data group 122 and the worker performance data group 123. As described with reference to FIG. 4, in the combination data 400, there is a start time for each combination of the operating state, the power supply state, the rotating state, and the working state. For example, a time is the start time of a combination of an operating state, a power state, a rotating state, and a working state, and after that time, there is no change in any of the operating state, the power state, and the rotating state. If the working state has changed, a new start time is recorded, and the combination corresponding to the new start time includes the changed working state (see, for example, columns 401A and 401B in FIG. 4). Similarly, a time is the start time of a combination of operating state, power state, rotating state and working state, and after that time, even if there is no change in working state, the operating state, power state and If any of the rotational states have changed, a new start time is recorded and the combination corresponding to the new start time includes the changed operating state, power state or rotational state (eg, FIG. 4). See columns 401B and 401C).
(S1002-2) The information management unit 141 performs a procedure for each worker 51 at the same time based on the combination data 400 (for example, based on the captured video data and the teacher data group 126 in addition to the combination data 400). Specify the details and specify the length between the times as the required time. For example, the information management unit 141 narrows down the candidates for the procedure details estimated from the captured moving image data to one candidate for a certain worker 51 based on at least one of the operating state, the power supply state, and the rotating state. The narrowed down candidates correspond to the identified procedure details. Further, for example, the information management unit 141 carries out the ID of the worker 51 and the worker 51 from at least a part of the site data group 121 (for example, the shooting video data of the worker 51) for each worker 51. Identify the ID of the product type to be worked on.
(S1002-3) For each worker 51, the information management unit 141 includes the specified work state, time interval, required time, procedure details (implementation procedure and number of implementations), worker ID, and product type ID. Person data 700 is created.

In S1003, the information management unit 141 selects one worker 51 from one or more unselected workers 51 in this educational content creation process.

In S1004, the information management unit 141 determines whether or not the selected worker 51 (the worker 51 selected in S1003) is a high-level worker. Specifically, the information management unit 141 describes the work state and product type ID represented by the worker data 700 of the selected worker 51, which are the work details represented by the worker data 700 (required time, implementation procedure). And at least one of the number of implementations) and the reference work details (at least one of the reference time, the reference procedure, and the reference number of times), which is the work details represented by the reference data group 125, and the difference as a result of the comparison is the second. It is determined whether or not the amount is 1 or less. This comparison may be, for example, a comparison of the feature quantities of the implementation work details and the reference work details, and the first quantity may be an example of the threshold value of the difference between the feature quantities. Specifically, for example, S1004 may include the following S1004-1 to S1004-3.
(S1004-1) The information management unit 141 determines whether or not the difference between the required time and the reference time is equal to or less than the first time. If the result of this determination is false, the result of the determination of S1004 is false.
(S1004-2) When the result of the determination in S1004-1 is true, the information management unit 141 determines whether or not the implementation procedure and the reference procedure match. If the result of this determination is false, the result of the determination of S1004 is false.
(S1004-3) When the result of the determination in S1004-2 is true, the information management unit 141 determines whether or not the difference between the number of executions and the reference number is equal to or less than the first value for each step constituting the implementation procedure. judge. If the result of this determination is false, the result of the determination of S1004 is false. When the result of this determination is true, the result of the determination of S1004 is true.

If the result of the determination in S1004 is true, in S1005, the content creation unit 142 creates the educational content 800 for the work state and the product type ID represented by the worker data 700 of the selected worker 51. The created educational content 800 includes all (or a part) of the worker data 700 of the selected worker 51, information representing the reference time of the required time represented by the worker data 700, and a video taken by the selected worker 51. Includes the video data portion of the data that corresponds to the implementation time.

In S1006, the content creation unit 142 stores the educational content 800 created in S1005.

In S1007, the information management unit 141 determines whether or not all the workers 51 have been selected. If the result of this determination is false, the process returns to S1003. If the result of this determination is true, the educational content creation process ends.

The above is an example of the educational content creation process.

With respect to the target period of the educational content creation process, a plurality of working states can be specified for one worker 51. In this case, the worker data 700 of the worker 51 may represent the work details for each set of the work state and the product type ID. Then, S1004 may be performed for each set of the working state and the product type ID. That is, the worker 51 is a high-level worker for a certain set of the work state and the product type ID, and is a high-level worker for another set of the work state and the product type ID. Not always (this is true for low-level workers as well). The educational content 800 may be created for each set of the working state and the product type ID.

Further, when there are a plurality of workers whose S1004 determination result is true for a set having the same work state and product type ID set, the difference between the implementation work details and the reference work details (for example, each feature amount). The worker 51 with the smallest difference) may be determined to be a high-level worker.

<Education program creation process>

FIG. 11 shows an example of the flow of the educational program creation process. The educational program creation process is performed regularly, for example.

S1101 and S1102 are the same as S1001 and S1002 shown in FIG. 10, respectively. When the data created in S1001 and S1002 shown in FIG. 10 can be diverted in this educational program creation process (for example, the period targeted for this educational program creation process is the target of the implemented educational content creation process). (Same as period), S1101 and S1102 may be skipped.

In S1103, the information management unit 141 selects one worker 51 from one or more unselected workers 51 in this educational program creation process.

In S1104, the information management unit 141 determines whether or not the selected worker 51 (the worker 51 selected in S1103) is a low-level worker. Specifically, the information management unit 141 describes the work state and product type ID represented by the worker data 700 of the selected worker 51, which are the work details represented by the worker data 700 (required time, implementation procedure). And at least one of the number of implementations) and the reference work details (at least one of the reference time, the reference procedure, and the reference number of times), which is the work details represented by the reference data group 125, and the difference as a result of the comparison is the second. It is determined whether or not the amount is 2 or less. This comparison may also be, for example, a comparison of the feature quantities of the implementation work details and the reference work details, and the second quantity may be an example of the threshold value of the difference between the feature quantities. The "second amount" may be the same amount as the "first amount" used in the educational content creation process, or may be a larger amount. Specifically, for example, S1104 may include the following S1104-1 to S1104-3.
(S1104-1) The information management unit 141 determines whether or not the difference between the required time and the reference time is larger than the second time. When the result of this determination is true, the result of the determination in S1104 is true. The "second time" may be the same as or longer than the "first time" in the educational content creation process.
(S1104-2) When the result of the determination in S1104-1 is false, the information management unit 141 determines whether or not the implementation procedure and the reference procedure do not match. When the result of this determination is true, the result of the determination in S1104 is true.
(S1104-3) If the result of the determination in S1104-2 is false, the information management unit 141 determines whether or not the difference between the number of executions and the reference number is larger than the second value for each step constituting the implementation procedure. Is determined. If the result of this determination is false, the result of the determination in S1104 is false. When the result of this determination is true, the result of the determination in S1104 is true. The "second value" may be the same as or larger than the "first value" in the educational content creation process.

If the result of the determination in S1104 is true, in S1105, the program creation unit 143 creates an education program 900 for the work state and the product type ID represented by the worker data 700 of the selected worker 51. The created educational program 900 includes educational content 800 corresponding to the work state and product type ID represented by the worker data 700 of the selected worker 51, and all (or a part) of the worker data 700 of the selected worker 51. , The moving image data portion 910 of the selection worker 51 and the knowledge data 950 are included. The moving image data portion 910 of the selection worker 51 is a part of the shooting moving image data of the selection worker 51 that corresponds to the execution time of the selection worker 51. The knowledge data 950 is the knowledge data corresponding to the educational target item (the item having a large difference among the differences between the implementation work details and the standard work details) in the knowledge data group 129. An example of an item to be educated is a step in which the difference between the number of implementations and the standard number of times is larger than the second value. The program creation unit 143 identifies the knowledge corresponding to the educational target item from the knowledge data group 129, acquires the knowledge data 950 of the knowledge from the knowledge data group 129, and includes the acquired knowledge data 950 in the educational program 900.

In S1106, the program creation unit 143 stores the educational program 900 created in S1105.

In S1107, the information management unit 141 determines whether or not all the workers 51 have been selected. If the result of this determination is false, the process returns to S1103. If the result of this determination is true, the educational program creation process ends.

The above is an example of the educational program creation process.

<Education provision processing>

The information providing unit 144 provides the education program 900 to the educated person of the education program 900 (that is, the worker 51 determined to have a low level of the work state and product type ID corresponding to the education program 900). For example, the worker 51C illustrated in FIG. 1 is an example of an educated person, and the information providing unit 144 distributes the educational UI 131 for the worker 51C to the information processing terminal 40 of the worker 51C. In the education UI 131, for example, the moving image represented by the moving image data portion of the high-level worker and the moving image represented by the moving image data portion of the worker 51C are simultaneously reproduced. Further, the education UI 131 displays the knowledge represented by the knowledge data 950 included in the education program 900.

The method of providing education is not limited to this method. For example, the information providing unit 144 may output the educational program 900 for each educated person as one package.

<Management notification processing>

The information providing unit 144 transmits various information to the management terminal 160. For example, when the information providing unit 144 creates one or more educational contents 800 or one or more educational programs 900, the information providing unit 144 provides information on the one or more educational contents 800 or the one or more educational programs 900. It may be transmitted to the management terminal 160. Further, for example, the information providing unit 144 may send an inquiry as to whether or not to approve the created educational content 800 or educational program 900 to the management terminal 160. If approval is answered to the inquiry (for example, if the administrator watches the video and determines that the educational content 800 or educational program 900 is appropriate), the educational content 800 or educational program to be approved is approved. 900 may be formally referred to as Educational Content 800 or Educational Program 900. If a refusal is answered to the inquiry, the information providing unit 144 may delete the educational content 800 or the educational program 900 to be rejected.

The above embodiments can be summarized as follows, for example.

The educational content creation system 101 includes an information management unit 141 and a content creation unit 142. The information management unit 141 represents the state of the worker 51 (element belonging to Man in 4M (Man, Machine, Material and Method)) and the time of the state, and the worker record data group 123 (an example of the worker record information). ) And the machine record data group 122 representing the state and state time of the machine 50 (an example of non-worker record information representing the state and state time of a non-worker, which is an element other than Man in 4M). And get. The content creation unit 142 specifies the details of the work performed by the worker during the same time from the work state and the machine state at the same time among the worker record data group 123 and the machine record data group 122. .. The content creation unit 142 creates the educational content 800 including the video data portion corresponding to the time interval (implementation time zone) of the specified work details in the shooting video data of the work performed by the worker. This makes it possible to easily create an appropriate educational content 800 based on the details of the work performed by the worker 51. In addition to the moving image data portion, the educational content 800 may include data representing at least a part of the implementation work details (for example, required time, implementation procedure, and number of implementations).

The information management unit 141 may identify a high-level worker who is a worker whose difference between the details of the implemented work and the details of the standard work is equal to or less than the first amount. The content creation unit 142 may create the educational content 800 including the video data portion of the specified high-level worker. As a result, the created educational content 800 can be made into a content including data representing a work video of a high-level worker, thereby improving the appropriateness of the automatically created educational content 800. Can be done.

The work details may include the required time, the procedure, and the number of times (the number of times each step constituting the procedure is performed). The required time corresponds to an example of an index of work proficiency, the procedure corresponds to an example of an index of work accuracy, and the number of times corresponds to an example of an index of work efficiency. A set of such elements is defined as work details. As a result, it is expected that the educational content 800 automatically created is highly appropriate.

The information management unit 141 may make a first determination as to whether or not the difference between the required time and the reference time is equal to or less than the first time. If the result of the first determination is false, it may be determined that the worker is not a high-level worker. The required time corresponds to an example of an index of work proficiency, and therefore, it is possible to appropriately determine whether or not the worker is a high-level worker.

For example, when the result of the first determination is true (or whether or not the first determination is performed), the information management unit 141 determines whether or not the implementation procedure and the reference procedure match. You may make a judgment. If the result of the second determination is false, it may be determined that the worker is not a high-level worker. The procedure corresponds to an example of an index of work accuracy, and therefore it is possible to appropriately determine whether or not a worker is a high-level worker.

If the result of the second determination is true, the information management unit 141 may make a third determination as to whether or not the difference between the number of executions and the reference number is equal to or less than a certain value for each step constituting the implementation procedure. .. If the result of the third determination is false, it may be determined that the worker is not a high-level worker. If the result of the third determination is true, it may be determined that the worker is a high-level worker. The number of implementations for each step corresponds to an example of an index of work efficiency, and therefore, it is possible to make a more appropriate determination as to whether or not the worker is a high-level worker.

The educational content creation system 101 may include an information providing unit 144 that provides the created educational content 800 (for example, the educational program 900 including the educational content 800). If the provided educational content 800 is displayed to the educated person, the educated person is educated, so that efficient education is possible.

The information management unit 141 may identify a low-level worker who is a worker whose difference between the details of the implemented work and the details of the standard work exceeds the second amount. The information providing unit 144 may provide the educational content 800 to the low-level worker. Further, as the logic for determining whether or not the worker 51 is a low-level worker, a logic for determining whether or not the worker 51 is a high-level worker can be adopted. As described above, the worker 51 who is desirable to be an educated person is efficiently identified, and the educational content 800 is provided to such a worker 51, so that more efficient education is expected.

The educational content creation system 101 may further include a program creation unit 143 that creates an educational program 900 including the created educational content 800 and work knowledge data 950 for the educated person. The information providing unit 144 may provide the education program 900 to the educated person. Since the educated person can browse the work knowledge in addition to the educational content 800, more efficient education is expected.

The program creation unit 143 has data on work knowledge according to which work detail item (for example, required time or step in the procedure) difference exceeds the threshold value in the difference between the implementation work detail and the standard work detail. The 950 may be identified from the knowledge data group 129 containing various work knowledge and the data 950 may be included in the education program 900. As a result, it can be expected that the knowledge represented by the data 950 included in the education program 900 is specialized in the work details where the educator is less proficient, and is therefore more efficient and appropriate. Education can be expected.

The education program 900 is a program that includes a video data portion representing a work video of a high-level worker and a video data portion representing a work video of an educated person, and the work videos of those workers are displayed in a comparable manner. .. As an example of "display in comparison", the work video of the high-level worker and the work video of the educated person may be displayed side by side (for example, side by side or side by side), or the work video of the high-level worker may be displayed side by side. And the work video of the educated person may be displayed in an overlapping manner. By comparing the work video of the educator with the work video of the high-level worker, the educator can identify the work detail part where the educator is less proficient, or master the work detail part. It is possible to efficiently identify a method for increasing the degree.

Although one embodiment has been described above, this is an example for explaining the present invention, and the scope of the present invention is not limited to this embodiment. The present invention can also be practiced in various other forms.

For example, in the above-described embodiment, various threshold values (for example, a threshold value of the difference between the required time and the reference time, a threshold value of the difference between the number of implementations and the reference number of times) are preset in the function using the threshold value. Alternatively, the setting may be appropriately changed by an administrator or the like.

Further, for example, in the above-described embodiment, the difference between the implementation work details and the reference work details may be expressed by an absolute value, or may be expressed by distinguishing between a positive value and a negative value. A finer-grained determination may be made depending on whether the difference is a positive value or a negative value.

Further, for example, in the above-described embodiment, Machine is adopted as an example other than Man among 4M (that is, in the above-described embodiment, 2M of Man and Machine is adopted), but other than Man. As an example, at least one of Material and Method may be adopted in place of or in addition to Machine. That is, in place of or in addition to the machine actual data group 122, a data group related to Material (for example, product 49) (for example, an actual data group indicating when and what part was added to product 49) and a data group related to Method (for example, product 49). , One of the actual data groups indicating when and what kind of tool was used), even if it is referred to together with the worker actual data group 123, the candidate of the work details estimated from the worker actual data group 123 can be selected. It can be narrowed down accurately. Specifically, for example, according to an example of a case where Material is adopted, if there is a work at a certain time, the press work is specified as the work details, and if there is no work, the press work is specified as the work details. May be excluded. According to an example of the case where Method is adopted, at a certain time, if there is a tool, the work using the tool is specified as the work details, and if there is no tool, the work is excluded as the work details. good. The data regarding at least one of Material and Method may be the data collected at the site 151, and in addition to the data, a device that manages at least one of Material and Method (for example, management terminal 160). It may be the data input from.
