[Embodiment 1]
<Overview>
FIG. 1 is a diagram conceptually showing processing performed by the information processing apparatus (information processing apparatus 2000 shown in FIG. 2) of the present embodiment. The information processing apparatus 2000 generates the display screen 10 including the first graph 12. The 1st graph 12 shows the time series data which represent in a distinguishable manner the time zone in which the volume in the equipment satisfies the standard and the time zone in which the volume in the equipment does not meet the standard. The equipment is a line or device operated in a factory, for example.

出来 Volume represents the amount of good products produced by the equipment. A non-defective product is a product that satisfies a predetermined quality standard among products produced by equipment. For example, when a product produced in a certain facility is used in the next facility, the product cannot be used in the next facility unless the product satisfies the quality standard. In such a case, a product that satisfies the quality standard is a non-defective product. On the other hand, a product that does not satisfy the standard quality, that is, a product that cannot be used in the next facility is a non-defective product (defective product).

The first graph 12 in FIG. The time zone in which the volume meets the standard is represented by a white square. On the other hand, the time zone when the volume does not meet the standard is represented by a rectangle filled with diagonal lines. Hereinafter, the fact that the volume does not meet the standard is also referred to as “the volume is insufficient”.

The lack of equipment volume may be due to the work of the person working on the equipment (hereinafter referred to as the operator). Various kinds of work can be conceived by the worker who can cause a shortage of the volume. For example, the operator may have made a mistake in the operation of the equipment, and the equipment has produced a defective product, which may have resulted in a shortage of output. In addition, for example, there is a time zone in which the operator could not operate the equipment even though the equipment was in a state where it was able to produce goods, and the equipment was idling during that time zone, so the volume was insufficient. There is also a possibility. From this, it is difficult to grasp the cause of the shortage of the volume only by the data indicating whether the volume meets the standard (that is, the first graph 12). For example, the first graph 12 in FIG. 1 shows that a shortage in volume occurs in one time zone, but the cause of the shortage in volume cannot be grasped only from the first graph 12.

Therefore, the information processing apparatus 2000 includes not only the first graph 12 but also the second graph 14 on the display screen 10. The second graph 14 represents the work status of the worker in time series. The work status is information indicating 1) which equipment is targeted, 2) what kind of work is progressing, and 3) how far. Therefore, for example, the work status is represented by a combination of an equipment identifier, a work type, and a progress status thereof.

For example, in the work status shown in FIG. 1, the target equipment is the equipment A, and the work type is the failure recovery work. The failure recovery operation is an operation for restoring a failed facility to a normal state. The progress statuses are notification confirmation, treatment start, and treatment end, respectively.

The progress status of notification confirmation is a state in which an input indicating that the work instruction from the computer has been confirmed is made when the operator operates the apparatus according to the instruction from the computer. The notification output or the input indicating that the notification has been confirmed is performed by, for example, a touch panel provided in a device operated by an operator. “Treatment” in the progress status of treatment start and treatment end is the main action of that type of work. For example, if the target facility is the facility A and the work type is a failure recovery operation, this is an action of correcting the failure location of the facility A. Further details of the work status will be described later.

The second graph 14 shows, for example, each work status of the worker in a mode in which the transition time (the time when the status is changed) that is the time when the status is changed to the status can be grasped. In FIG. 1, each work status of the worker is represented by a point (circle) on the time axis. A time point corresponding to a point representing each work status represents a transition time of the work status. As shown in FIG. 1, white circles and hatched circles represent the statuses of notification confirmation and treatment, respectively.

In addition, when showing the data about the work status (work status which continues for a fixed time) in time, the 2nd graph 14 is the time of changing to the work status, and the time of changing from the status to another status (that is, The start status and the end time of the work status may be shown in a manner that can be grasped. The work status having a range in time may include a status such as “in process”. The start time point and end time point of the work status “in process” indicate the time point when the treatment starts and the time point when the treatment ends, respectively. For example, by representing the work status with a rectangle on the time axis, both the start time and the end time can be represented.

Referring to the first graph 12 and the second graph 14, it is possible to obtain information about the work status that may be the cause of the shortage of volume. For example, in a time zone in which the volume satisfies the standard in the second graph 14 of FIG. 1, notification confirmation is performed at the start time of each time zone, and treatment is started. On the other hand, for the time zone in which the shortage of the volume occurs, the notification confirmation timing and the treatment start timing are later than the start time of the time zone in which the volume shortage occurs. From this, work start delay can be considered as a cause of the shortage of volume.

<Effect>
As described above, according to the information processing apparatus 2000 of the present embodiment, the first graph 12 that shows, in time series, the time zone in which the volume of equipment meets the standard and the time zone in which the volume of equipment does not meet the standard; A display screen 10 including the second graph 14 representing the work status of the worker in time series is output. As a result, the user of the information processing device 2000 (for example, an operator or an administrator who manages the operation of a factory, etc.) displays the time zone in which the volume does not satisfy the standard and the work status of the worker in that time zone. It can be easily compared. Therefore, it becomes easy for the user to grasp the cause of the shortage in volume. For example, the cause such as “the start of treatment is delayed” can be grasped. Further, for example, it is possible to easily grasp what work the worker has started at what time and how long it has been performed in a time zone in which the volume does not satisfy the standard.

As described above, the above description with reference to FIG. 1 is an example for facilitating the understanding of the information processing apparatus 2000, and does not limit the functions of the information processing apparatus 2000.

Hereinafter, the information processing apparatus 2000 of the present embodiment will be described in more detail.

<Example of Functional Configuration of Information Processing Device 2000>
FIG. 2 is a diagram illustrating a functional configuration of the information processing apparatus 2000 according to the first embodiment. The information processing apparatus 2000 includes a first generation unit 2020, a second generation unit 2040, and an output unit 2060. The first generation unit 2020 generates the first graph 12. As described above, the first graph 12 represents the time zone in which the production amount of the non-defective product satisfies the standard and the time zone in which the production amount of the non-defective product does not meet the standard in a time series so that they can be distinguished from each other. The second generation unit 2040 generates the second graph 14. As described above, the second graph 14 represents the work status of the worker in time series. The output unit 2060 outputs the display screen 10 including the first graph 12 and the second graph 14.

<Hardware Configuration of Information Processing Device 2000>
Each functional component of the information processing apparatus 2000 may be realized by hardware (eg, a hard-wired electronic circuit) that implements each functional component, or a combination of hardware and software (eg: It may be realized by a combination of an electronic circuit and a program for controlling it). Hereinafter, the case where each functional component of the information processing apparatus 2000 is realized by a combination of hardware and software will be further described.

FIG. 3 is a diagram illustrating a computer 1000 for realizing the information processing apparatus 2000. The computer 1000 is an arbitrary computer. For example, the computer 1000 is a personal computer (PC) or a server machine. The computer 1000 may be a dedicated computer designed for realizing the information processing apparatus 2000 or a general-purpose computer.

The computer 1000 includes a bus 1020, a processor 1040, a memory 1060, a storage device 1080, an input / output interface 1100, and a network interface 1120. The bus 1020 is a data transmission path through which the processor 1040, the memory 1060, the storage device 1080, the input / output interface 1100, and the network interface 1120 transmit / receive data to / from each other. However, the method of connecting the processors 1040 and the like is not limited to bus connection.

The processor 1040 is various processors such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and an FPGA (Field-Programmable Gate Array). The memory 1060 is a main storage device realized using a RAM (Random Access Memory) or the like. The storage device 1080 is an auxiliary storage device realized by using a hard disk, an SSD (Solid State Drive), a memory card, or a ROM (Read Only Memory).

The input / output interface 1100 is an interface for connecting the computer 1000 and an input / output device. For example, the input / output interface 1100 is connected to an input device such as a keyboard and an output device such as a display device. The network interface 1120 is an interface for connecting the computer 1000 to a communication network. This communication network is, for example, “LAN (Local Area Network)” or “WAN (Wide Area Network)”. A method of connecting the network interface 1120 to the communication network may be a wireless connection or a wired connection.

The storage device 1080 stores a program module that implements each functional component of the information processing apparatus 2000. The processor 1040 implements a function corresponding to each program module by reading each program module into the memory 1060 and executing the program module.

<Process flow>
FIG. 4 is a flowchart illustrating the flow of processing executed by the information processing apparatus 2000 according to the first embodiment. The first generation unit 2020 generates the first graph 12 (S102). The second generation unit 2040 generates the second graph 14 (S104). The output unit 2060 outputs the display screen 10 including the first graph 12 and the second graph 14 (S106).

<About volume standards>
It is assumed that the standard defined for the output volume, that is, the standard defined for the production amount of non-defective products is predetermined for each facility. For example, the information indicating the volume standard for each facility is stored in a storage device accessible by the first generation unit 2020.

”“ The volume meets the standard ”means that the production volume of non-defective products is greater than or equal to the standard level. For example, for the facility A, it is assumed that a standard “5 good products are produced per second” is set. In this case, the time zone in which the number of non-defective products produced by the equipment A per second is 5 or more is the time zone in which the volume of the equipment A satisfies the standard. On the other hand, the time zone in which the number of non-defective products produced by the facility A is less than 5 is a time zone in which the output of the facility A does not meet the standard.

¡Multiple volume standards may be set for one facility. In this case, each time zone can be classified as a time zone in which the volume meets the strictest standard, a time zone in which the volume meets the second strictest standard,..., A time zone in which the volume does not satisfy any of the standards. That is, when N standards are set for a certain facility, N + 1 types of time zones are displayed on the first graph 12 for that facility so that they can be distinguished from each other. For example, it is assumed that the first standard of “producing 10 good products per second” and the second standard of “producing 5 good products per second” are set for the facility A. In this case, in the first graph 12 for the equipment A, the time zone in which the volume of the equipment A satisfies the first standard, the time zone in which the volume of the equipment A does not meet the first standard and satisfies the second standard, and Three types of time zones, ie, time zones in which the volume of equipment A does not satisfy the second standard, are displayed so as to be distinguishable from each other.

<Generation of First Graph 12: S102>
The first generation unit 2020 generates the first graph 12 (S102). As described above, the first graph 12 shows time-series data that identifiable the time zone in which the volume at the facility satisfies the standard and the time zone in which the volume at the facility does not meet the standard.

The equipment that the first generation unit 2020 generates as the first graph 12 is specified by a user operation, for example. An existing technique can be used as a specific technique for realizing designation of a graph generation target.

However, the method for specifying the generation target of the first graph 12 is not limited to designation by a user operation. For example, the equipment to be generated in the first graph 12 may be determined in advance by default. In this case, the target equipment can be changed by a user operation.

The first generation unit 2020 acquires information related to the volume of the equipment to be generated in the first graph 12. Hereinafter, information on the volume of equipment is called volume information. FIG. 5 is a diagram illustrating volume information in a table format. The table shown in FIG.

The table 100 has three columns of an equipment identifier 102, a volume 104, and a time zone 106. Each record of the table 100 indicates the volume in the time zone indicated in the time zone 106 as the volume 104 for the equipment specified by the equipment identifier 102. The time zone 106 is represented by a combination of the start time and end time of the time zone, for example.

The first generation unit 2020 determines whether the volume of each time zone satisfies the standard. Specifically, the 1st production | generation part 2020 uses the volume information of the equipment made into the production | generation object of the 1st graph 12, and compares the volume of the installation in each time slot | zone with the reference | standard of the volume about the equipment. Thus, it is determined whether or not the volume in each time zone satisfies the standard.

However, it is not always necessary for the first generation unit 2020 to determine whether the volume meets the standard. For example, the volume information may include information indicating whether the volume satisfies a standard. In this case, the 1st production | generation part 2020 can grasp | ascertain whether the volume of each time slot | zone satisfy | fills a reference | standard by referring volume information.

Suppose here that there are multiple volume standards. In this case, an identifier is assigned to each criterion. Then, the identifier of the strictest standard among the standards that are satisfied is included in the volume information.

The length of each time slot in the first graph 12 (for example, the horizontal width of each square in the first graph 12 in FIG. 1) is determined by, for example, volume information. In this case, the 1st production | generation part 2020 produces | generates one data (For example, the square in the 1st graph 12 of FIG. 1) included in the 1st graph 12 for every record contained in volume information.

However, the length of each time slot in the first graph 12 need not be determined by the volume information. For example, the length of each time zone is determined in advance. Specifically, the length of the time zone is set to 10 minutes. In this case, in the first graph 12, the time axis is divided in units of 10 minutes (for example, 12:00 to 12:10, 12:10 to 12:20, etc.). The first generation unit 2020 refers to the volume information for each of the time zones thus divided, thereby specifying whether or not the volume satisfies the standard in the time zone, and the first generation unit 2020 determines the first based on the specification result. A graph 12 is generated.

Here, the 1st production | generation part 2020 produces | generates the 1st graph 12 about a certain specific period. For example, in FIG. 1, the first graph 12 is generated from 12:00 to 13:00 on February 1, 2017. For example, the specific period is specified by a user operation. In addition, for example, the specific generation period is determined by the first generation unit 2020 based on the current date and time. For example, the first generation unit 2020 generates the first graph 12 for one day of the current date. Note that when the first graph 12 is generated for a certain day, what time from what time to what time is set as the specific period may be determined in advance or specified by a user operation. Further, the specific period may be from the first time zone to the last time zone indicated by the volume information for the day.

The first graph 12 can be a graph of any format that can represent data in time series. For example, as shown in FIG. 1, it is possible to employ a graph in which different displays are shown on the time axis in a time zone in which the volume meets the standard and a time zone in which the volume does not meet the standard. Note that the display does not have to be a square, and may be another figure or point. When the time zone is represented by a point, for example, the point indicates the start time, end time, or middle time of the time zone.

1st graph 12 does not necessarily need to show a mutually different display in the time zone which meets a standard, and the time zone which does not meet a standard. For example, the first graph 12 is a graph (such as a line graph representing the transition of the volume) in which the vertical axis represents the volume and the horizontal axis represents time. In this case, the first graph 12 includes data representing the volume reference. By doing so, it is possible to distinguish between a time zone in which the volume meets the standard and a time zone in which the volume does not meet the standard.

FIG. 6 is a diagram illustrating the first graph 12 representing the transition of the trading volume. In FIG. 6, the vertical axis indicates the volume, and the horizontal axis indicates time. The solid line represents the transition of the trading volume, and the dotted line represents the trading volume standard. The time zone in which the volume meets the standard is a time zone in which the solid line is above the dotted line. On the other hand, the time zone in which the trading volume does not meet the standard is a time zone in which the solid line is below the dotted line.

In this way, when the graph representing the transition of the trading volume is the first graph 12, the trading volume information is information representing the transition of the trading volume for each facility.

In addition, a display that makes it easy to identify a time zone in which the volume meets the standard and a time zone in which the volume does not meet the standard may be added to the graph representing the transition of the volume in this way. For example, in FIG. 6, a method may be considered in which a solid line in a time zone in which the volume meets the standard and a solid line in a time zone in which the volume does not meet the standard are different color lines. In this case, it is not necessary to display the dotted line indicating the volume reference.

<About work status>
As described above, the work status is information representing what work has progressed to what extent. For example, the work status is represented by a combination of the identifier of the target equipment, the work type, and the progress status. It should be noted that the work status may include a status indicating that no work is being performed (that is, a status indicating a break).

* Various types of work can be adopted in addition to the above-described failure recovery work. For example, there are types of work such as setup work, cutting tool replacement work, rework work, and production preparation work. The setup work is a preparation work for changing an object created by the apparatus. For example, this preparation includes an operation of changing a mold set in the apparatus. The cutting tool replacement work is a work for replacing the cutting tool. The rework work is a work for reworking a defective product when the defective product is produced. Production preparation work is work required for preparation for production, such as starting of an apparatus, for example.

As the progress status, not only “notification confirmation”, “treatment start”, and “treatment completion” described above, but various things can be adopted. For example, progress such as movement, arrival or waiting for material may be employed. The movement is a situation where the movement to the target equipment is started. “Arrival” is a situation where the object arrives at the target facility. The material waiting state is a state in which the material necessary for the treatment is waiting to be carried. In addition, for example, progress status such as a cause investigation indicating a situation in which the cause of the failure is investigated in the failure recovery work may be employed.

Furthermore, the above progress may be subdivided. For example, when the treatment can be divided into a plurality of phases, each phase can be used instead of “treatment”. For example, when the treatment is divided into phases A and B, progress statuses such as “End of phase A” and “Start of phase B” can be adopted.

<Generation of Second Graph 14: S104>
The second generation unit 2040 generates the second graph 14. The second graph 14 represents the work status of the worker in time series.

The second generation unit 2040 generates the second graph 14 representing the work status of the worker in time series for the worker who is the generation target of the second graph 14. For example, the worker is designated by a user operation. An existing technique can be used as a specific technique for realizing designation of a graph generation target.

In addition, for example, a user operation for selecting a facility may be received, and the second graph 14 may be generated for the worker of the facility. It is assumed that the facility operator is determined in advance. For example, information that associates the identifier of the facility with the identifier of the worker is stored in a storage device that is accessible from the second generation unit 2040. The second generation unit 2040 identifies the worker of the selected facility by acquiring the worker identifier associated with the selected facility identifier.

In addition, for example, the second generation unit 2040 may automatically determine the worker who is the generation target of the second graph 14. For example, the second generation unit 2040 specifies an operator of a facility that is a generation target of the first graph 12 and sets the worker as a generation target of the second graph 14.

2nd generation part 2040 is good also as a generation target of the 2nd graph 14 also for an operator of facilities other than the installation made into the generation target of the 1st graph 12. For example, the second generation unit 2040 sets the operator of the facility located immediately before the facility to be generated in the first graph 12 as the generation target of the second graph 14. For example, if the progress of work is delayed in the facility located immediately before the facility A (the facility that produces the material used by the facility A), this may cause a shortage of the volume of the facility A. Therefore, it can be said that the information about the work status of the worker who is in charge of the facility located immediately before the facility A is useful for grasping the cause of the shortage of the volume of the facility A.

In order to generate the second graph 14, the second generator 2040 acquires work information. The work information indicates information on the work status of the worker in each facility. FIG. 7 is a diagram illustrating work information in a table format. The table shown in FIG. The table 200 includes an operator identifier 202, a status 204, and a time zone 206. Each record of the table 200 indicates the work status of the worker specified by the worker identifier 202 in the status 204.

Status 204 indicates equipment identifier 208, type 210, and progress status 212. The equipment identifier 208 indicates an identifier of equipment to be worked. The type 210 indicates the type of work. The progress status 212 indicates the progress status of the work.

The time zone 206 indicates a start time 214 and an end time 216. The start time 214 represents the time at which transition to the work status represented by the record is made. The end time 216 represents the time when the work status represented by the record transits to another work status. Note that only the start time 214 may be indicated for statuses relating to work that is not continued, such as “notification confirmation”.

The method for generating work information is arbitrary. For example, according to the progress of the work, the worker inputs information related to the work progress (target equipment, work type, progress, etc.) to a predetermined terminal. Then, the information processing apparatus 2000 and other arbitrary apparatuses generate work information using the input information. It is preferable that the time indicated in the work information is automatically set to the time when input is received from the worker.

The above-mentioned predetermined terminal is, for example, a portable terminal possessed by the worker or a PC PC installed near each facility. Here, any method can be adopted as a method for the operator to input. For example, key input using a keyboard, touch operation using a touch panel, or voice input using a microphone can be used.

Here, the voice input will be described in more detail. For example, at the time when the work status changes (when the notification about the work is confirmed, when the work is started, when the work is finished, etc.), the worker performs a voice input indicating that. For example, a voice representing a progress status such as “notification confirmation”, “work start”, “work end”, or the like is input. Work information is generated in response to the voice input. Specifically, first, the progress status corresponding to the input voice is specified. For example, the progress status corresponding to the voice “notification confirmation” is “notification confirmation”. In addition, the target equipment and work type associated with the progress are specified. The target equipment and work type are input in advance by an arbitrary method before the progress status is input. Further, the time when the voice input is accepted is used as the transition time included in the work information. Work information is generated using the above information.

As the second graph 14, a graph of an arbitrary format that can be displayed in time series so that a plurality of data can be distinguished from each other can be adopted. For example, the second graph 14 is a graph in which one time axis is shown for each worker, and points corresponding to each record of the table 200 are plotted on the time axis. When there is a status of starting and ending for a certain work, the start to the end of the work may be represented by one graphic (for example, a rectangle).

<Generation of first display screen: S106>
The output unit 2060 generates the display screen 10 including the first graph 12 and the second graph 14 (S106). The output unit 2060 preferably arranges the first graph 12 and the second graph 14 so that the time axes of the first graph 12 and the second graph 14 are aligned on the display screen 10. Here, “the time axes of two graphs are aligned” means, for example, that the time axes of two graphs are parallel to each other, and the time points on the same perpendicular passing through these time axes are the same time points. Means to represent. However, the time points on the vertical line passing through the time axis of the first graph 12 and the second graph 14 do not necessarily coincide exactly. A certain time point on the time axis of the first graph 12 and that point on the time axis of the second graph 14 are in the vertical direction of the screen (when the time axis is horizontal) or the horizontal direction (the time axis is vertical). In other words, it should be visible to the human eye as if they are in agreement.

The display screen 10 generated by the output unit 2060 may be an image representing a screen, or data capable of generating an image representing a screen by performing a predetermined process. An example of the latter is an “HTML” file. When the display screen 10 is generated as an “HTML” file, an image representing the display screen 10 is generated by processing the HTML file with an application such as a browser.

<Output of display screen 10>
The output unit 2060 outputs the display screen 10. There are various output methods of the display screen 10. FIG. 8 is a diagram illustrating a variation of the output method of the first display screen.

8, the output unit 2060 displays the display screen 10 on the display device 30 connected to the information processing device 2000. On the other hand, in the lower case of FIG. 8, the output unit 2060 transmits the display screen 10 to the external terminal 40 that is communicably connected to the information processing apparatus 2000. Then, the external terminal 40 displays the display screen 10 on the display device 50 connected to the external terminal 40. In the lower case of FIG. 8, for example, the information processing apparatus 2000 functions as a server apparatus, and the external terminal 40 functions as a client apparatus.

<Other functions>
<< Highlighting >>
It is preferable that the information processing apparatus 2000 has a function that makes it easier to grasp the relationship between the time period when the volume is insufficient and the work status of the worker. For example, the information processing apparatus 2000 receives a user operation for designating a certain time zone in the first graph 12. For example, in the first graph 12 of FIG. 1, each square can be selected by a tap operation, a click operation, or the like. In response to this user operation, the output unit 2060 highlights the data of the work performed in the time zone specified in the first graph 12 in the second graph 14.

FIG. 9 is a diagram illustrating an example in which highlighting is performed for the second graph 14 in accordance with the selection of data in the first graph 12. In the upper part of FIG. 9, the data 60 of the first graph 12 is selected. Here, in the second graph, the data representing the work included in the time zone represented by the data 60 is the plot 70-1 and the plot 70-2. Therefore, the output unit 2060 highlights these plots by making the plots 70-1 and 70-2 larger than the other plots 70 as shown in the lower part of FIG. The highlighting method is not limited to the method of enlarging the plot. In FIG. 9, the data selected in the first graph 12 is also highlighted.

Here, there is a possibility that not only the work performed in the time period when the shortage of volume occurred but also the work performed before that time period is the cause of the shortage of the volume. Therefore, the output unit 2060 may further highlight the work status before the time period selected in the first graph 12 in response to a user operation for selecting a certain time period in the first graph 12. For example, the output unit 2060 displays the work status with the latest transition time among the work statuses before the time zone selected in the first graph 12 (that is, the work status immediately before the time zone selected in the first graph 12). ) Is highlighted. In addition, for example, the output unit 2060 highlights a predetermined number of work statuses in order of late transition time among work statuses before the time period selected in the first graph 12, or selects the selected time period. Each work status from the start time to a predetermined time before may be highlighted.

In addition, for example, the output unit 2060 may automatically determine the work status to be highlighted in the second graph 14 based on the time zone in which the volume is insufficient. In this case, the output unit 2060 specifies the work status to be highlighted by treating the time zone in which the volume is insufficient as in the time zone selected by the user operation described above. In other words, the output unit 2060 highlights the work status in the time zone where the volume is insufficient, or highlights the work status before the time zone where the volume is insufficient.

<< Display of captured image corresponding to work status >>
When any of the work statuses shown in the second graph 14 (circles in the second graph 14 in FIGS. 1 and 9) is selected, the output unit 2060 is associated with the work status. A captured image may be output. The captured image associated with the work status is an image obtained by capturing an image of a worker in the work status (time at which the work status is changed or before and after the time) with a camera. For example, a camera is installed between each facility or between facilities so that each worker can be imaged.

FIG. 10 is a diagram illustrating an example in which a captured image is displayed in accordance with the selection of the work status in the second graph 14. In the upper part of FIG. 10, the user has selected the plot 70. As a result, in the lower part of FIG. 10, the captured image 15 corresponding to the work status indicated by the plot 70 is displayed.

The worker's image is included in each record of the work information and stored in the storage device, for example. The captured image included in each record of work information is an image generated by capturing an image of a worker with a work status specified by the record with a camera. For example, such an image may include an object of work (product, equipment, equipment, etc.) by the worker, or the worker and the object.

The captured image associated with the work status may be an image generated by a still camera that captures a still image, or may be an image frame constituting a moving image generated by a video camera.

Note that a moving image (a plurality of captured images) may be associated with the work status. In this case, the output unit 2060 may output a moving image associated with the selected work status, or output a moving image frame (for example, the first moving image frame of the moving image) constituting the moving image. Also good.

[Usage example]
Here, a specific usage example of the information processing apparatus 2000 will be described. The usage example shown here is an example of a situation in which the information processing apparatus 2000 is used to facilitate understanding of the information processing apparatus 2000, and limits the situation in which the information processing apparatus 2000 is used. is not.

FIG. 11 is a diagram illustrating a display screen 10 of a usage example. The target selection area 16 is an input area for selecting equipment or the like to be generated in the first graph 12. First, in the target date and time column, for which date and time the first graph 12 and the second graph 14 are generated can be selected. For example, in FIG. 11, the first graph 12 and the second graph 14 are generated using the volume information and work information as of December 17, 2017.

The devices to be generated in the first graph 12 can be narrowed down in the line selection column. For example, in FIG. 11, line A is selected in the line selection field. Therefore, the volume of each device included in the line A is displayed in the first graph 12.

As a result of selecting line A in the line selection column, the configuration of line A is displayed in the line display column. In line A of this example, three devices M1 to M3 are arranged in order. Therefore, the devices M1 to M3 are sequentially displayed in the line display column.

The line display column includes a display indicating whether or not each device included in the line A is operating. A device on which a white circle is superimposed represents a device that is operating normally. On the other hand, a device on which a hatched circle is superimposed represents a device in failure. In this example, the device M2 is out of order and the other devices are operating normally.

In the first graph 12, the volume data of each device included in the line A is displayed. In this first graph 12, two criteria for the volume are provided. If the volume meets the strict criteria, it means that the volume is good. If the volume meets only the standard of the looser, it means that the volume is sluggish (not bad). If the standard for the loose volume is not met, it means that the volume is bad.

In the first graph 12, the time zone where the volume is good is represented by a white square, the time zone where the volume is sluggish is represented by a diagonal pattern, and the time zone where the volume is bad is a dot. It is represented by a rectangular pattern. In practice, it is preferable that the time zone with a good volume is represented by a color reminiscent of a favorable situation such as green. On the other hand, it is preferable to express a time zone in which the volume is not good by a color reminiscent of an unfavorable situation such as red or yellow. For example, good volume, low volume, and poor volume are represented using green, yellow, and red, respectively.

The first graph 12 may display the volume only for a part of the devices, not all the devices included in the line selected in the line selection column. For example, only the output of the device selected by the user is displayed on the first graph 12. The device that is the generation target of the first graph 12 can be specified by, for example, an operation of selecting a device in the line display column (for example, an operation of tapping a picture of the device).

In this usage example, worker 1 is in charge of work on line A. Therefore, the transition of the work status of the worker 1 is displayed on the second graph 14.

Below the second graph 14, a table showing details of the work status of each worker is displayed. Each record of this table corresponds to each plot of the second graph.

As shown in FIG. 11, it is possible to grasp whether or not work is being performed appropriately by the worker by arranging data representing the volume, operation status, and worker status in time series. For example, when an equipment failure occurs, it is possible to grasp whether or not the worker has moved to the equipment immediately after that, and whether or not the trouble recovery work has been performed smoothly after arriving at the equipment. it can. For example, if there is a large time difference between the time when the equipment failure occurs and the time when the worker starts moving to the equipment where the equipment has failed, it can be understood that the start of dealing with the equipment failure was delayed. In addition, for example, if the waiting time for the material is long, it can be understood that the transportation of the material is delayed.
