First example embodiment

< overview >

Fig. 1 is a diagram conceptually showing a process performed by the information processing apparatus of the present exemplary embodiment (the information processing apparatus 2000 shown in fig. 2). The information processing apparatus 2000 is an apparatus that generates a display including a graphic relating to a lost time in the operation of devices in a factory or the like. The apparatus is, for example, a production line or a device. Loss is a factor that prevents a device from fully exploiting the capabilities that the device would otherwise have.

First, the information processing apparatus 2000 generates a first display screen 10 including the first graphic 12, and outputs the generated first display screen 10. The first graph 12 is a graph representing, for each device, the time lost and the net operating time for each of a plurality of types of losses. For example, in fig. 1, the first graph 12 is a belt graph representing, for each device, the ratio of time lost to net operating time for each of three types of losses (loss 1, loss 2, and loss 3).

The "lost time" is a time from a point in time when the loss occurs to a point in time when the loss ends. In addition, the net operating time is the time during which no loss occurs during operation of the device. For example, in the case where the apparatus is operated for 12 hours a day and at least one loss occurs within 4 hours of 12 hours, the net operation time is 8 hours.

The information processing apparatus 2000 receives an input for selecting any device in the first graphic 12. For example, the input operation is an operation of touching the touch panel on which the first display screen 10 is displayed. Note that the first display screen 10 is not necessarily required to be displayed on the touch panel. A modification of the input operation will be described later.

The information processing apparatus 2000 that receives the input operation generates the second display screen 20 including the second graphic 22, the second graphic 22 being for the device selected by the input operation, and outputs the generated second display screen 20. For the selected device, the second graph 22 represents the length of time of occurrence of each loss in the device in time series.

For example, in fig. 1, with respect to the first graphic 12, an input operation of the selection device 1 is performed. Thus, the information processing apparatus 2000 generates the second display screen 20 including the second graphic 22 for the device 1. The second graph 22 of fig. 1 is a line graph showing the length of the occurrence time of each of the loss 1, the loss 2, and the loss 3 in the device 1 within each time slice (for example, per hour) in time series.

< action and Effect >

According to the information processing apparatus 2000 of the present exemplary embodiment, the first display screen 10 including the first graphic 12 is output, the first graphic 12 representing, for each device, the time lost by each of the plurality of types of losses and the net operation time. Thus, it is possible to easily identify, for example, the time at which each loss occurs in each device, the length of the net operation time, and the ratio of each loss to the net operation time.

Further, a device is selected on the first display screen 10, and a second display screen 20 including a second graphic 22 is output, the second graphic 22 representing the length of occurrence time of each loss in the selected device in time series.

Accordingly, the lost detailed data in the device of interest to the user can be easily viewed.

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

< example of functional configuration of information processing apparatus 2000 >

Fig. 2 is a diagram showing a functional constitution of an information processing apparatus 2000 according to the first exemplary embodiment. The information processing apparatus 2000 includes a first generation unit 2020, an input reception unit 2040, and a second generation unit 2060. The first generation unit 2020 generates a first display screen 10 including the first graphic 12 and outputs the generated first display screen 10. For each device, the first graph 12 represents the time lost in operation of the device for each of a plurality of types of losses and the net operating time. The input receiving unit 2040 receives an input operation of selecting any device in the first graphic 12. The second generation unit 2060 generates the second display screen 20 including the second graphic 22 and outputs the generated second display screen 20, the second graphic 22 being for the device selected by the input operation. For the selected device, the second graph 22 shows the length of time that the loss occurred in time series.

< hardware Structure of information processing apparatus 2000 >

Each of the functional constituent units of the information processing apparatus 2000 may be realized by hardware (e.g., a hard-wired electronic circuit or the like) that realizes each of the functional constituent units, or may be realized by a combination of hardware and software (e.g., a combination of an electronic circuit and a program that controls the electronic circuit). Hereinafter, a case where each of the functional constituent units of the information processing apparatus 2000 is realized by a combination of hardware and software will be further described.

Fig. 3 is a diagram showing a computer 1000 for implementing the information processing apparatus 2000. The computer 1000 is any computer. For example, the computer 1000 is a Personal Computer (PC), a server machine, or the like. The computer 1000 may be a special purpose computer designed to implement the information processing apparatus 2000, or may be 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. Bus 1020 is a data transmission path through which processor 1040, memory 1060, storage device 1080, input output interface 1100, and network interface 1120 send and receive data to and from each other. However, the method of connecting the processors 1040 and the like to each other is not limited to bus connection.

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

The input-output interface 1100 is an interface for connecting the computer 1000 to input and output devices. For example, an input device such as a keyboard and an output device such as a display device are connected to the input-output interface 1100. The network interface 1120 is an interface for connecting the computer 1000 to a communication network. The communication network is, for example, a Local Area Network (LAN) or a Wide Area Network (WAN). The 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 program modules that implement each of the functional constituent units of the information processing apparatus 2000. Processor 1040 achieves the functionality corresponding to each program module by reading each program module into memory 1060 and executing the program module.

< procedure >

Fig. 4 is a flowchart showing the flow of processing performed by the information processing apparatus 2000 according to the first exemplary embodiment. The first generation unit 2020 generates a first display screen 10 including the first graphic 12 (S102). The first generation unit 2020 outputs the first display screen 10 (S104). The input receiving unit 2040 receives an input operation of selecting any device in the first graphic 12 (S106). The second generation unit 2060 generates the second display screen 20 including the second graphic 22 for the device selected by the input operation (S108). The second generation unit 2060 outputs the second display screen 20 (S110).

< loss >

The information processing apparatus 2000 processes information on various types of losses in the job. For example, as the loss, each of seven main losses included in evaluating the operation efficiency of the equipment in a factory or the like may be employed. Seven major losses include, for example, setup, tool, production readiness, failure stop, defect, interference, and speed losses.

The setup loss is a loss associated with the setup job. The setting operation is a preparation operation for replacing a product produced with the apparatus. For example, the preparation includes a work of replacing the mold provided in the apparatus. The blade loss is a loss associated with replacement of the blade. More specifically, the loss of the blade includes time loss associated with regular replacement of the blade and replacement due to breakage, and loss such as time required for defective products or repair defective products generated before and after replacement. Production readiness loss is the loss associated with readiness for production. The preparation for production is, for example, the operation of the apparatus, etc. The failure stop loss is a loss due to a stop associated with a device failure. Defect loss is loss due to defects occurring in the resulting product. The interference loss is a waiting loss caused by mutual interference between the devices or between the devices and the worker. As a more specific example, in the case where the equipment is stopped due to a temporary equipment failure or a cooperative work is performed between an idle device and another device, the interference loss is a loss accompanying the exchange of the article between these devices. Alternatively, in the case where another device needs to wait for completion of a job executed in the faulty device, the interference loss is a loss accompanying job stagnation (waiting) in the other device. In another example, for example, assume that device B uses the components generated by device a. In this case, it takes time to deliver the components generated by device a to device B. This time becomes an interference loss in the apparatus B. The speed loss is a loss due to the fact that the speed of the device manufacturing product is lower than the standard speed.

Here, the setting loss, the cutting tool loss, and the production preparation loss are all losses caused by the work performed by the person. Here, these three losses can be pooled and treated as one loss. The loss obtained by aggregating these three losses is referred to as a human working time loss.

< generation of first display screen 10: s102 ]

The first generation unit 2020 generates the first display screen 10 (S102). For this purpose, the first generation unit 2020 generates the first graphic 12 included in the first display screen 10. As described above, the first graph 12 represents, for each device, the time lost for each of the multiple types of losses, as well as the net operating time.

To generate the first graphic 12, the first generation unit 2020 acquires loss information. The loss information is information indicating, for each device, the time of each of the plurality of types of losses and the net operation time. Fig. 5 is a diagram showing loss information in a table form. The table in fig. 5 is referred to as table 200. Table 200 has a device identifier 202, a data type 204, a time 206, a start time 208, and an end time 210. The device identifier 202 indicates an identifier of the device.

In the case of data related to loss, the data type 204 indicates the type of loss (set loss, sharps loss, etc.). In addition, time 206 represents the length of the loss. Further, the start time 208 indicates the time when the loss starts, and the end time 210 indicates the time when the loss ends. In other words, the start time 208 indicates the time when the loss occurred, and the end time 210 indicates the time when the cause of the loss occurred was eliminated.

On the other hand, in the case of data related to a net operation time, the data type 204 indicates data related to a net operation time. In addition, time 206 indicates the length of the net operation time. Further, the start time 208 indicates a time when the device operation starts, and the end time 210 indicates a time when the device operation is completed.

Note that time 206 is a value obtained by subtracting start time 208 from end time 210. Thus, table 200 may not include time 206. In this case, the first generation unit 2020 calculates the length of the loss and the length of the net operation time by subtracting the start time 208 from the end time 210.

Note that in the case where the same loss occurs multiple times in a certain device, the total loss time in the device can be calculated by accumulating the loss times indicated by the loss information.

The first generation unit 2020 generates a first graphic using the loss information and generates a first display including the generated first graphic. Here, various formats of graphics may be employed as the first graphics. Preferably, however, the first pattern 12 is a pattern that allows a comparison between the loss and the length of the net operating time. The graphic includes, for example, a stacked bar graph. The stacked bar graph may be obtained by stacking the lengths of the loss and the net operation time in the vertical direction or in the horizontal direction.

The first graph 12 may show the length of lost or net operating time as absolute or relative values. In the latter case, for example, the first graphic 12 uses a ratio such as a percentage to show the length of lost or net operating time relative to the total operating time.

The first graph 12 shows the loss and the length of net operating time during a predetermined period of operation. For example, the predetermined operation period is one day, one week, or one month. The predetermined operation period may be predetermined or may be set by a user of the information processing apparatus 2000. In addition, the predetermined operation period may be the latest period (for example, the latest day or the latest week), or may be a period decided by the user selection.

Preferably, the first graphic 12 includes all of the seven major losses described above. However, some of these seven main losses can be pooled and treated as one. For example, as described above, a method of handling the setting loss, the cutting tool loss, and the production preparation loss as one of the loss of the human working time can be adopted. In addition, the first graphic 12 need not necessarily include all of the seven major losses. The loss to be included in the first graphic 12 may be predetermined or may be set by a user of the information processing apparatus 2000.

The first graphic 12 may include only graphics for a production line, may include only graphics for a device, or may include graphics for both a production line and a device. In the case where graphics for both the production line and the device are included in the first graphics 12, it is preferable that each device included in the first graphics 12 is a device included in any production line included in the first graphics 12.

In addition, in the case where graphics for both the production line and the device are included in the first graphics 12, the form of the first graphics 12 for the production line and the form of the first graphics 12 for the device may be the same as each other or may be different from each other. For example, in a specific example to be described later, the first pattern 12 for the production line is a stacked bar chart in the vertical direction, and the first pattern 12 for the device is a stacked bar chart in the horizontal direction. Note that the form of the first graphic 12 may be predetermined or may be set by the user of the information processing apparatus 2000.

Note that after the first display screen 10 is output, the user may change settings (the above-described predetermined operation period, the type of loss, the form of the graphic, and the like) related to the first graphic 12.

Here, the first display screen 10 generated by the first generation unit 2020 may be an image representing the first display screen 10, or may be data capable of generating an image representing the first display screen 10 by performing predetermined processing. As an example of the latter, for example, an HTML file is cited. In the case where the first display screen 10 is generated as an HTML file, an image representing the first display screen 10 is generated by processing the HTML file using an application such as a browser.

< output of first display screen: s104 ]

The first generation unit 2020 outputs the first display screen 10. There are various methods for outputting the first display screen 10. Fig. 6 is a diagram showing a modification of the method of outputting the first display screen.

In the upper case of fig. 6, the first generation unit 2020 causes the display device 30 connected to the information processing device 2000 to display the first display screen 10. In contrast, in the lower case of fig. 6, the first generation unit 2020 transmits the first display screen 10 to the external terminal 40 communicably connected to the information processing device 2000. Further, the external terminal 40 causes the display device 50 connected to the external terminal 40 to display the first display screen 10. In the lower case of fig. 6, for example, the information processing apparatus 2000 functions as a server apparatus, and the external terminal 40 functions as a client apparatus.

< input of information processing apparatus 2000: s106 ]

The input receiving unit 2040 receives an input operation of selecting any device in the first graphic 12 (S106). Here, the prior art may be used as a technique for receiving an input for selecting any one of a plurality of objects in the case where graphics for the plurality of objects (devices in the first graphics 12) are displayed.

< generation of the second display screen: s108-

The second generation unit 2060 generates the second display screen 20 (S108). The second display 20 includes a second graphic 22 for the device selected by the input operation. Each second graph 22 shows the length of time each loss occurs in time series.

Here, in order to display the length of the loss occurrence time in time series, the length of the loss occurrence time is indicated for each predetermined time slice. Any length such as one hour or one day may be employed, as the length of the time slices (i.e., the granularity of the second graphic 22 in the time direction) may be any length. The length of the time slices may be preset or may be set by a user of the information processing apparatus 2000. In addition, the length of the time slice may be changed by an input operation after the second display screen 20 is displayed.

Here, the second pattern 22 is preferably generated for each type of loss. For example, in the case where the second display screen 20 includes seven kinds of the second graphics 22 that are mainly lost, seven kinds of the second graphics 22 are included in the second display screen 20.

However, there are also cases where some losses are collected and summarized as one type of loss, as in the case of using the above-described human work time loss. In this case, a second graph 22 is preferably generated by pooling the losses (which are pooled into a single loss). The second graph 22 in which pieces of information about a plurality of losses are collected may show data of each loss separately, or may show one data obtained by adding times of a plurality of losses.

The form of the second graphic 22 may be set to any form that may represent time-series data. For example, a line graph, bar graph, distribution graph, or the like may be used.

Here, the second display screen 20 may include not only the second graphic 22 but also the first graphic 12. At this time, the second graphic 22 does not necessarily include the first graphic 12 for all devices. However, it is preferable that the first graphic 12 of the device selected for the input operation received by the input receiving unit 2040 is included in the second display screen 20. In this way, the first graphic 12 and the second graphic 22 of the selected device can be viewed simultaneously, so that the user easily recognizes information about the selected device (i.e., the device that the user is interested in).

In addition, in the case where the first graphic 12 for the device other than the selected device is also included in the second display screen 20, a preferable state is that the selected device can be distinguished from other devices on the second display screen 20. For example, in the first graphic 12 included in the second display screen 20, information about the selected device is highlighted (highlighted, enclosed with a frame, etc.).

The position of the first graphic 12 on the second display 20 may be the same as or different from the position of the first graphic 12 on the first display 10. Fig. 7 is a diagram showing the positions of the first graphic 12 on the first display screen 10 and the second display screen 20. In the upper example of fig. 7, the first graphic 12 is included on the left side of the first display screen 10, while the right side is blank. On the second display screen 20, the second graphic 22 is displayed at a blank portion in the first display screen 10. However, on the first display screen 10, the portion does not necessarily need to be set to be blank. For example, the portion may include a coordinate axis of the second graphic 22 or the like in advance (refer to a use example which will be described later).

In the lower example of fig. 7, the position of the first graphic 12 on the first display screen 10 and the position of the first graphic 12 on the second display screen 20 are different from each other. Specifically, on the first display screen 10, the first graphic 12 is displayed near the center. On the other hand, on the second display screen 20, similar to the example on the upper part of fig. 7, the first graphic 12 is displayed on the left side, and the second graphic 22 is displayed on the right side.

Note that in the lower example of fig. 7, the first graphic 12 on the first display 10 may be larger than the first graphic 12 on the second display 20. For example, on the first display screen 10, the size of the first graphic 12 is set to be substantially the same as the entire screen, and the first graphic 12 is reduced to a size corresponding to the left half of the second display screen 20 on the second display screen 20.

< output of the second display screen 20: s110 ]

The second generation unit 2060 outputs the generated second display screen 20 (S110). Here, as a method of outputting the second display screen 20, the same output method as that of outputting the first display screen 10 may be employed.

< input operation on the second display screen 20 >

Here, in the case where the first graphic 12 is also included in the second display screen 20, the information processing apparatus 2000 may process the second display screen 20 as the first display screen 10. In this case, the input receiving unit 2040 receives an input for selecting a device for the first graphic 12 included in the second display screen 20. As a result, the second generation unit 2060 generates and outputs the second display screen 20 including the second graphic 22 for the selected device.

Application example

Here, a specific use example of the information processing apparatus 2000 will be described. The use examples shown here are provided to show examples of the case of using the information processing apparatus 2000 so that the information processing apparatus 2000 can be easily understood, which is not limited to the case of using the information processing apparatus 2000.

Fig. 8 is a diagram showing a first display screen 10 of a use example. On the first display screen 10, a first graphic 12 is displayed on the left side. In addition, on the right side, coordinate axes of the second graphic 22 and the like are shown.

In the first graph 12, data for each production line is shown on the upper side. On the other hand, data for each device is shown on the underside.

The losses handled in the use case include the seven main losses described above. However, in the first pattern 12, the setting loss, the cutting tool loss, and the production preparation loss are handled as losses of human working time. In addition, losses other than the seven main losses will be pooled as "others".

In the case where any device included in the first graphic 12 is selected, a second display screen 20 including a second graphic 22 for that device is generated. Fig. 9 is a diagram showing the second display screen 20. In fig. 9, device K is selected. Thus, the second graph 22 showing the occurrence time of each loss in the device K in time series is displayed. Here, on the second display screen 20, in the first graphic 12 for the selected device, each of the name of the device and the data related to the device is surrounded by a thick frame.

The second pattern 22-1 is a pattern of a loss of human working time in the apparatus K. Here, the second graph 22-1 shows data showing the respective lengths of the set-up loss, the sharpening loss, and the production readiness loss.

The second pattern 22-2 is a pattern of a failure stop loss in the device K.

The second pattern 22-3 is a pattern of defect loss in the device K. The graph includes data indicating a defect rate in addition to data indicating a length of defect loss. Defect rate is the ratio of defective products to the total number of products produced.

The second pattern 22-4 is a pattern of velocity loss and interference loss in the device K. The graph includes data indicating a cycle time and data indicating a machine time. Here, the cycle time refers to a time required for one operation process, and the machine time refers to a time during which the machine is operating in the time required for one operation process. That is, the difference between the cycle time and the machine time is the conveyance time between processes, and the difference between the cycle time and the machine time becomes long in the case where the work object cannot be conveyed from the previous process or the work object cannot be conveyed to the next process for some reason. In the conveyance time between the processes, the time exceeding the conveyance standard time is an interference loss.

In the second graph 22-4, the loss of interference can be identified by comparing the cycle time to the machine time. Note that data representing the difference between the cycle time and the machine time, data representing the conveyance standard time, data directly representing the interference loss (data obtained by further subtracting the conveyance standard time from the difference between the cycle time and the machine time), and the like may be included in the graph 22-4.

The speed loss time is the difference between the actual time required for the device to manufacture the product and the time required as a criterion determined based on the standard speed. That is, the speed loss time is the difference between the actual machine time (the actual measured machine time in fig. 9) and the ideal machine time. Thus, for example, a speed loss may be identified from the data of the actual measured machine time shown in the second graph 22-4. Note that the second graph 22-4 may include data representing an ideal machine time or data directly representing a loss of speed (data representing a difference between an actual measured machine time and an ideal machine time).

In the above, although the exemplary embodiments of the present application are described with reference to the drawings, the exemplary embodiments are examples of the present application, and various configurations other than the above may be adopted.

While some or all of the example embodiments are described in the following supplementary description, the present application is not limited thereto.

1. An information processing apparatus comprising:
