[ first example embodiment ]

< overview >

Fig. 1 is a diagram conceptually showing processing performed by the information processing apparatus (the information processing apparatus 2000 shown in fig. 2) of the present exemplary embodiment. The information processing apparatus 2000 is an apparatus that generates a display including a graph relating to lost time in operation of equipment in a plant or the like. The apparatus is for example a production line or a plant. The loss is a factor that hinders the apparatus from fully utilizing the original ability of the apparatus.

First, the information processing apparatus 2000 generates the 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 of each of the plurality of types of loss and the net operating time. For example, in fig. 1, the first graph 12 is a band diagram representing, for each device, the ratio of the time of each of the three types of losses (loss 1, loss 2, and loss 3) to the net operating time.

The "loss time" is a time from a time point at which a loss occurs to a time point at which the loss ends. In addition, the net operating time is the time during which no losses occur during operation of the apparatus. For example, where the device is operating for 12 hours a day and loss occurs at least once within 4 of 12 hours, the net operating 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 a touch panel on which the first display screen 10 is displayed. Note that the first display screen 10 does not necessarily need to be displayed on the touch panel. A modification of the input operation will be described later.

The information processing apparatus 2000 that has received the input operation 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 represents the length of the occurrence time of each loss in the device in time series.

For example, in fig. 1, as for the first graphic 12, an input operation of the selection apparatus 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 that represents the length of time of occurrence of each of the loss 1, the loss 2, and the loss 3 in the apparatus 1 in 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 graph 12 representing, for each device, the time of each of the plurality of types of loss and the net operation time is output. Accordingly, it is possible to easily identify such things as 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 the occurrence time of each loss in the selected device in time series.

Thus, detailed data of loss 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 configuration of an information processing apparatus 2000 according to a 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 the 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 of each of the plurality of types of loss in operation of the device and the net operating time. The input receiving unit 2040 receives an input operation to select an arbitrary device in the first graphic 12. The second generation unit 2060 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. The second graph 22 represents the length of the loss occurrence time in time series for the selected device.

< hardware configuration of information processing apparatus 2000 >

Each function constituting unit of the information processing apparatus 2000 may be realized by hardware (for example, a hard-wired electronic circuit or the like) that realizes each function constituting unit or by a combination of hardware and software (for example, a combination of an electronic circuit and a program that controls the electronic circuit). Hereinafter, a case where each functional constituent unit 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 dedicated 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. 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 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 the 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 configured 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), or 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 a communication network may be a wireless connection or a wired connection.

The storage device 1080 stores a program module that realizes each functional constituent unit of the information processing apparatus 2000. Processor 1040 implements the functions corresponding to each program module by reading it into memory 1060 and executing it.

< treatment Process >

Fig. 4 is a flowchart showing a flow of processing performed by the information processing apparatus 2000 according to the first exemplary embodiment. The first generation unit 2020 generates the 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 to select an arbitrary 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).

< about loss >

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

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

Here, all of the setup loss, the blade loss, and the production preparation loss are losses due to work performed by a person. Here, the three losses can be collected and treated as one loss. The loss obtained by pooling these three losses is referred to as human work time loss.

< generation of first display screen 10: s102>

The first generation unit 2020 generates the first display screen 10 (S102). To this end, 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 the time of each of the plurality of types of loss and the net operation time for each device.

To generate the first graph 12, the first generation unit 2020 acquires loss information. The loss information is information indicating, for each device, a time of each of a plurality of types of loss and a 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. The 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 relating to a 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 at which the loss starts, and the end time 210 indicates the time at which the loss ends. In other words, the start time 208 indicates the time when the loss occurs, and the end time 210 indicates the time when the cause of the loss occurrence is eliminated.

On the other hand, in the case of data relating to net operation time, the data type 204 indicates data relating to net operation time. Additionally, time 206 indicates the length of the net operating time. Further, a start time 208 indicates a time at which device operation begins and an end time 210 indicates a time at which device operation is complete.

Note that the time 206 is a value obtained by subtracting the start time 208 from the 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 in a certain device a plurality of times, 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 screen including the generated first graphic. Here, various formats of graphics may be adopted as the first graphics. Preferably, however, the first graph 12 is a graph that allows a comparison between the loss and the length of the net operating time. The graphics include, for example, stacked bar graphs. The stacked bar graph may be obtained by stacking the lengths of loss and net operating time in the vertical direction or in the horizontal direction.

The first graph 12 may show the length of the loss or net operating time as an absolute or relative value. In the latter case, the first graph 12 shows the length of lost or net operating time relative to the total operating time using a ratio such as a percentage, for example.

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

Preferably, the first pattern 12 includes all of the seven major losses described above. However, a portion of these seven major losses can be pooled and treated as one loss. For example, as described above, a method of dealing with the setting loss, the blade loss, and the production preparation loss as a loss of the working time of the person may be adopted. In addition, the first graph 12 does not necessarily need to 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 the user of the information processing apparatus 2000.

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

In addition, in the case where the patterns for both the production line and the apparatus are included in the first pattern 12, the form of the first pattern 12 for the production line and the form of the first pattern 12 for the apparatus 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 graphic 12 for the production line is a stacked bar graph in the vertical direction, and the first graphic 12 for the apparatus is a stacked bar graph 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 can change the settings (the above-described predetermined operation period, the type of loss, the form of graphics, and the like) relating 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, an HTML file is given. 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 case of the upper part 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 case of the lower part 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 apparatus 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 case of the lower part 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 to select an arbitrary device in the first graphic 12 (S106). Here, the related art may be used as a technique of receiving an input for selecting any one of a plurality of objects (devices in the first graphic 12) in a case where a graphic for the plurality of objects is displayed.

< generation of first display screen: s108>

The second generation unit 2060 generates the second display screen 20 (S108). The second display screen 20 includes a second graphic 22 for the device selected by the input operation. Each second graph 22 represents the length of the occurrence time of each loss 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 expressed for each predetermined time slice. Any length such as an hour or a day may be used, as the length of the time slice (i.e., the granularity of the second graphic 22 in the time direction) may be any length. The length of the time slice may be set in advance or may be set by the 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 graph 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 major loss second graphics 22, seven second graphics 22 are included in the second display screen 20.

However, there is also a case where some losses are collected and aggregated into one type of loss, as in the case of the above-described loss of human work time. In this case, a second graph 22 is preferably generated by aggregating losses (which are aggregated as a loss). The second graph 22 in which pieces of information on a plurality of kinds of losses are collected may show data of each kind of loss, respectively, or may show one data obtained by adding times of a plurality of losses.

The second graph 22 may be provided in any form that can represent time-series data. For example, a line graph, bar graph, profile, 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 graphics 12 for all devices. However, it is preferable that the first graphic 12 for the device selected by the input operation received by the input receiving unit 2040 is included in the second display screen 20. In this manner, the first graphic 12 and the second graphic 22 of the selected device may be viewed simultaneously, so that the user easily recognizes information about the selected device (i.e., the device of interest to the user).

In addition, in the case where the first graphic 12 for a device other than the selected device is also included in the second display screen 20, it is a preferable state 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 emphatically displayed (highlighted, surrounded with a frame, or the like).

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 illustrating 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, and the right side is blank. On the second display screen 20, a 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 coordinate axes of the second graphic 22 and 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, the first graphic 12 is displayed on the left side and the second graphic 22 is displayed on the right side, similar to the example on the upper part of fig. 7.

Note that, in the lower example of fig. 7, the first graphic 12 on the first display screen 10 may be larger than the first graphic 12 on the second display screen 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 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 adopted.

< input operation with respect to 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, for the first graphic 12 included in the second display screen 20, the input receiving unit 2040 receives an input for selecting a device. 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 example shown here is provided to show an example of a case where the information processing apparatus 2000 is used in order to easily understand the information processing apparatus 2000, which does not limit the case where the information processing apparatus 2000 is used.

Fig. 8 is a diagram showing the first display screen 10 of the 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 and the like of the second graphic 22 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 lower side.

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

In the case where any device included in the first graphic 12 is selected, the second display screen 20 including the 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. Therefore, 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 relating to the device is surrounded with a thick frame.

The second graph 22-1 is a graph of the loss of working time for the person in the device K. Here, the second graph 22-1 shows data showing the respective lengths of setup loss, tooling loss, and production set loss.

The second graph 22-2 is a graph of the fault stopping loss in the device K.

The second pattern 22-3 is a pattern of defect loss in the device K. The pattern comprises data indicating a defect rate in addition to data indicating a length of defect loss. The defect rate is a 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 indicative of a cycle time and data indicative of a machine time. Here, the cycle time refers to a time required for one work process, and the machine time refers to a time during which the machine is working in the time required for one work process. That is, the difference between the cycle time and the machine time is the transfer time between the processes, and the difference between the cycle time and the machine time becomes longer in a case where the work object cannot be transferred from the previous process or the work object cannot be transferred to the next process for some reason. Among the transport times between the respective processes, a time exceeding the transport standard time is an interference loss.

In the second graph 22-4, the loss of interference can be identified by comparing the cycle time with the machine time. Note that data indicating the difference between the cycle time and the machine time, data indicating the conveyance standard time, data directly indicating 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 pattern 22-4.

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

Hereinabove, although the exemplary embodiments of the present invention have been described with reference to the drawings, the exemplary embodiments are examples of the present invention, and various configurations other than the above may be employed.

Although some or all of the example embodiments are described in the following supplementary explanation, the present invention is not limited thereto.
