[Technical Field]

[0001] The present invention relates to the management of the operation of devices, machinery, and equipment (hereinafter simply referred to as equipment) for manufacturing pharmaceuticals and other products, and in particular to a technology for managing manufacturing history information including audit trails for equipment. [Background technology]

[0002] With the spread of IoT (Internet of Things), the collection and management of manufacturing history information, such as equipment operation history and setting history, is currently underway. For example, as part of data integrity, in the manufacture of pharmaceuticals and food products, it is required to record the details of events that occur, such as changes to control and settings for these.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-220127 Summary of the Invention [Problem to be solved by the invention]

[0005] In managing equipment operations, it is necessary to record setting history information such as "when," "who," "what," "how," and "why" regarding settings made by users. If a computer system were to store these setting histories each time, the processing load for storing them would increase, and the amount of storage would become enormous, which could result in necessary information being buried. Furthermore, it is common for products to be manufactured using multiple pieces of equipment. Therefore, in order to comprehensively manage manufacturing, it is necessary to aggregate the history information of each of the multiple pieces of equipment. Therefore, an object of the present invention is to efficiently collect manufacturing history information, particularly more appropriate setting history, for manufacturing performed using multiple pieces of equipment.

[0011] In this embodiment, multiple pieces of equipment work together to manage production. First, FIG. 1 is a diagram showing the concept of this embodiment. In this embodiment, processing is performed in the following sequence: "setting" - "control" - "collection of production history information" - "use of production history information." First, settings for each piece of equipment regarding production are made in response to input from an operator, etc.

[0012] Furthermore, in accordance with the "settings," "control" is executed for each piece of equipment to manufacture the product. As a result, each piece of equipment operates in cooperation to execute the manufacturing process, thereby manufacturing the product. Furthermore, manufacturing history information indicating the manufacturing history, such as the "settings," "control," and operations corresponding to these, is collected ("manufacturing history information collection"). The collected manufacturing history information is then used ("manufacturing history information utilization"). This "manufacturing history information utilization" includes controlling the equipment, allocating shared resources, and analyzing defects such as the occurrence of defective products. Furthermore, in this embodiment, it is sufficient to enable the "manufacturing history information utilization," and the processing may be limited to "manufacturing history information collection."

[0013] Next, the configuration of this embodiment will be described. Fig. 2 is a system configuration diagram showing a manufacturing system in this embodiment. The manufacturing system is composed of a history information management device 1, terminal devices 2-1 to 2-3, control devices 3-1 to 3-3, equipment 4-1 to 4-3, shared resource equipment 5, and a management device 6, and is connected via a network 7. Note that the numbers of terminal devices 2-1 to 2-3, control devices 3-1 to 3-3, equipment 4-1 to 4-3, and shared resource equipment 5 are merely examples and are not limited to 3 or 1, respectively. Furthermore, hereinafter, terminal devices 2-1 to 2-3, control devices 3-1 to 3-3, and equipment 4-1 to 4-3 will also be collectively referred to as terminal device 2, control device 3, and equipment 4, respectively.

[0014] In the manufacturing system, the control device 3 controls the equipment 4 according to settings from the terminal device 2. As a result, each piece of equipment 4 operates according to control and executes a manufacturing process, thereby manufacturing a product. During this process, the equipment 4 may use shared resources from the shared resource equipment 5 as needed. For example, in the manufacturing system, pharmaceuticals are manufactured as products. In this case, the equipment 4 executes manufacturing processes such as portioning and melting, which are directly related to the manufacture of the product, as well as cleaning and packaging.

[0015] The history information management device 1 manages the manufacturing history information for such manufacturing. This manufacturing history information is information related to manufacturing by various related devices such as the terminal device 2, the control device 3, the equipment 4, and the shared resource equipment 5. For example, the manufacturing history information includes the details of settings made in response to inputs from an operator to the terminal device 2, the details of control by the control device 3 in accordance with the settings, and the operating status of the equipment 4. The details of operation of the equipment 4 and the remaining amount of shared resources in the shared resource equipment 5, such as a shared resource storage, can also be used as manufacturing history. Furthermore, in this embodiment, the history information management device 1, the terminal device 2, the control device 3, and the management device 6 constitute a history information management system. The history information management device 1 is connected to related devices such as the control device 3 to constitute the history information management system, and collects manufacturing history information from any of these devices.

[0016] Next, we will explain each device that makes up the manufacturing system shown in Figure 2. First, the history information management device 1 is a device for managing manufacturing history information. To this end, the history information management device 1 has an input unit 11, a history information collection unit 12, a history information utilization unit 13, an output unit 14, and a storage unit 15.

[0017] First, the input unit 11 receives manufacturing history information from at least one related device among the terminal device 2, the control device 3, the equipment 4, and the shared resource equipment 5. It is also desirable that the input unit 11 receives the operation status of the equipment 4 and the shared resource equipment 5 via the control device 3. The operation status also includes the remaining amount of the shared resource in the shared resource equipment 5.

[0018] Furthermore, the history information collecting unit 12 collects manufacturing history information and operation statuses via the input unit 11. To this end, the history information collecting unit 12 may output a collection instruction to the related devices via the input unit 11 according to predetermined conditions, such as every cycle, or may collect manufacturing history information that is output voluntarily from the related devices. The history information collecting unit 12 then stores the collected manufacturing history information and operation statuses in the storage unit 15 as manufacturing history information 151 and equipment information 153. In this way, the history information collecting unit 12 executes the manufacturing history collection of FIG. 1.

[0019] Furthermore, the history information utilization unit 13 utilizes the collected manufacturing history information 151 and provides feedback to the manufacturing of the product. For example, the unit 13 may allocate the shared resources required for use by any equipment 4 according to the remaining amount of the shared resources, or may perform pre-reading to control downstream equipment 4-3 according to the operating status of equipment 4-1. The history information utilization unit 13 may also search the collected manufacturing history information 151. Furthermore, the history information utilization unit 13 may identify the content of utilization, such as control, based on the range of influence due to the manufacturing history indicated by the manufacturing history information 151. For example, the history information utilization unit 13 may implement control over equipment 4 indicated by the range of influence.

[0020] The output unit 14 outputs the processing results of the history information utilization unit 13, and outputs instructions to collect manufacturing history information to related devices in response to instructions from the history information collection unit 12. The storage unit 15 stores manufacturing history information 151, impact extent identification rules 152, equipment information 153, and product information 154. These pieces of information will be described below.

[0021] FIG. 3 is a diagram showing the manufacturing history information 151 used in this embodiment. The manufacturing history information 151 is information indicating the manufacturing history of the manufactured products produced by various related devices. For this reason, as shown in FIG. 3, the manufacturing history information 151 has items such as time, related devices, and content for each classification. First, the classification indicates classification such as the settings and operation of the manufacturing history information 151. Furthermore, in addition to normal settings, important items indicating more important settings may be set for the settings. Here, important items refer to items that affect the quality of the manufactured products and the manufacturing process of other equipment 4. An impact on the manufacturing process means a change in the time of the manufacturing process, or a change in the quantity or yield of intermediate products or manufactured products, or a high probability of such changes.

[0022] Furthermore, the time indicates the time when the corresponding manufacturing history information 151 was collected. This collection time includes the time when it was collected, and the time when it was operated or set. Furthermore, the related equipment indicates the related equipment related to the corresponding manufacturing history information 151, and individually identifies the terminal device 2, the control device 3, the equipment 4, and the shared resource equipment 5.

[0023] For example, if settings are recorded as a classification, the terminal device 2 that accepted the input for the setting history is recorded as the related device. In addition, a control device 3 that records a setting history including setting values ​​according to the input to the terminal device 2 and performs control in accordance with this, and a facility 4 that operates in accordance with the control device 3 may also be recorded. Furthermore, in the case of manufacturing history information 151 related to a shared resource (the fifth record in FIG. 3), the facility 4-3 and shared resource facility 5 that use the shared resource are recorded as related devices. The control device 3 controls the operation of the corresponding facility 4, i.e., the manufacturing process, in accordance with these setting values.

[0024] Furthermore, the content indicates the content of the corresponding manufacturing history information 151. For example, when a setting is recorded as a classification, a setting history including the setting value is recorded. In particular, for important items, it is desirable to record a setting history consisting of meaningful plain text data. As this plain text data, it is desirable to record the setting history for each item regarding the meaning of "when," "who," "what," "how," and "reason." For this reason, the setting history can be treated as an audit trail.

[0025] Here, history information such as the manufacturing history information 151 is usually made available through manual intervention or through text data that can be tampered with. For this reason, by handling plain text data that does not require manual intervention or the use of text data, it is possible to prevent or deter easy external access to the manufacturing history information 151. In addition, in the case of the manufacturing history information 151 relating to a shared resource (the fifth record in FIG. 3), the contents include the actual usage of the shared resource, as well as the planned usage and allocation for the equipment that will be used. Furthermore, when operation is recorded as a setting in the classification, an operation history indicating the operating status is recorded as the contents. Note that a setting history composed of such important items is referred to as an important setting history.

[0026] 4 is a diagram showing the impact extent identification rule 152 used in this embodiment. The impact extent identification rule 152 is a rule related to monitoring in manufacturing, and is preferably used to identify the impact extent corresponding to the manufacturing history and to perform manufacturing management according to the monitoring results. For this reason, the impact extent identification rule 152 has items for classification, condition, and impact extent for each related device.

[0027] First, the classification indicates the classification of the manufacturing history that is the condition for the impact range. This is the same item as the classification shown in FIG. 3. The condition is the condition in the manufacturing history when identifying the impact range. Furthermore, the impact range indicates the impact range when the corresponding condition is met. This impact range includes the quality of the product, related equipment, and manufacturing process. As a result, when the history information utilization unit 13 detects something that meets the condition in the manufacturing history information 151, it utilizes the corresponding impact range, such as control. For example, the manufacturing history information 151 indicates that if setting history is recorded that changes the amount of equipment 4-1 by ±5% or more, there is a possibility that quality will be affected.

[0028] Furthermore, the impact range identification rule 152 also indicates that if the operation of the manufacturing process of equipment 4-1 starts late (+α minutes), it will affect manufacturing process 2 (the next manufacturing process), and it is necessary to control the next manufacturing process 2 so that it is delayed by x minutes.

[0029] Next, Fig. 5 is a diagram showing equipment information 153 used in this embodiment. The equipment information 153 indicates the operating status of the equipment 4 and the shared resource equipment 5 (collectively referred to as equipment) of the manufacturing system. For this purpose, the equipment information 153 has items for function and operating status for each piece of equipment. The function indicates the function that the relevant piece of equipment has.

[0030] The operating status indicates the operating status of the equipment in operation. The operating status may include not only the details of the operation to execute the manufacturing process, but also maintenance such as cleaning, the allocated amount of shared resources, and the remaining amount of shared resources. Note that the operating status may be omitted because it is recorded as an operating history in the contents of the manufacturing history information 151. Furthermore, the history information utilization unit 13 can realize utilization processes such as control using the equipment information 153.

[0031] Next, FIG. 6 is a diagram showing product information 154 used in this embodiment. The product information 154 indicates a manufacturing method for a product manufactured in a manufacturing system, and manufacturing is carried out in accordance with this method. For this reason, the product information 154 records, for each product, the operating entity of each manufacturing process and the manufacturing details. The operating entity indicates which piece of equipment 4 is performing the operation. In the example of FIG. 6, one piece of equipment 4 is shown for each manufacturing process, but multiple pieces of equipment 4 that perform the manufacturing process in cooperation may be recorded, and for manufacturing processes that use shared resources, shared resource equipment 5 may be recorded.

[0032] The details of the manufacturing process include items and quantities. The items indicate the name of the manufacturing process, such as weighing. The quantities indicate various numerical values ​​in the corresponding manufacturing process. For example, the quantities of raw materials and processing time are recorded. These correspond to the setting history described above and are recorded according to input to the terminal device 2.

[0033] This concludes the explanation of the information used in this embodiment, and returning to FIG. 2, the configuration of the terminal device 2 and subsequent devices will be explained. The terminal device 2 is an information processing device (computer) operated by an operator. The terminal device 2 receives input from the operator regarding the setting history of production and notifies the control device 3, and acquires and displays the production status of the relevant equipment 4 from the control device 3. Here, the terminal device 2 is preferably realized by an HMI (Human Machine Interface), but can also be realized by a PC, tablet terminal, smartphone, etc.

[0034] The control device 3 also connects to the corresponding terminal device 2 and equipment 4, and controls the manufacturing process of the equipment 4 based on the setting history according to input from the terminal device 2 and a predetermined setting history. To this end, the control device 3 stores the above-mentioned settings. Furthermore, the control device 3 acquires the manufacturing status of the equipment 4. This manufacturing status and settings are collected by the history information management device 1. More preferably, the control device 3 stores important setting items (important setting history) so that they can be distinguished from the others. The control device 3 can be realized by a PLC (Programmable Logic Controller).

[0035] Furthermore, the equipment 4 executes the manufacturing process in accordance with control commands from the control device 3. The equipment 4 can be realized by a belt conveyor, a sensor, a robot, or a combination of these. Furthermore, the shared resource equipment 5 is equipment for managing shared resources such as sterilized water. Therefore, it can be realized by a shared resource storage facility that stores the shared resources. The terminal device 2 and the control device 3 may also be provided for the shared resource equipment 5.

[0036] The management device 6 is an information processing device (computer) operated by an administrator who manages the manufacturing system. The management device 6 displays the manufacturing status acquired from the control device 3 and searches for required information from the history information management device 1. For this reason, the management device 6 can be realized by a PC, a tablet terminal, a smartphone, or the like.

[0037] Furthermore, a network 7 connects the above-mentioned devices. This network 7 may be a local network such as within a factory, or may be realized as a wide area network spanning multiple factories. In the latter case, the history information management device 1 may be realized as a cloud system that manages the manufacturing history information 151 of multiple manufacturing systems. This concludes the description of this embodiment, and below, Examples 1 to 3, which are specific examples of this embodiment, will be described. [Example]

[0038] In the first embodiment, the important setting history among the setting history of the manufacturing history information 151 is stored and managed in a predetermined storage area (address) of the control device 3. More preferably, the important setting history is processed as plain text data, that is, an audit trail. Details of this will be described below.

[0039] First, Fig. 7 is a system configuration diagram showing a manufacturing system in Example 1. The following mainly describes the differences from Fig. 2. The basic functions of the devices constituting the manufacturing system in Example 1 are the same as those shown in Fig. 2. In particular, the equipment 4 and the shared resource equipment 5 are the same as those shown in Fig. 2.

[0040] Hereinafter, each device constituting the manufacturing system of Example 1 will be described. First, the history information management device 1 has an input unit 11, a setting history collection unit 121, a setting history search unit 131, an output unit 14, and a storage unit 15. First, the input unit 11 receives a setting history as manufacturing history information from a control device 3, which is one of the related devices. In this example, the setting history that is received is one that corresponds to an important item.

[0041] Furthermore, setting history collection unit 121 is an example of history information collection unit 12, and collects setting histories, particularly important setting histories, via input unit 11. Then, setting history collection unit 121 stores the collected setting histories as setting history information 1511. This setting history information 1511 is an example of manufacturing history information 151. The setting history information 1511 will be described later.

[0042] Furthermore, the setting history search unit 131 is an example of the history information utilization unit 13, and executes a search on the setting history information 1511. Here, since the setting history information 1511 indicates important setting history, relatively highly necessary information can be efficiently searched. Furthermore, according to a more preferred aspect of the first embodiment, the setting history is handled as plain text data (audit trail). As described above, it is difficult to easily access this plain text data. Therefore, according to this aspect, the security of the setting history can be ensured.

[0043] The output unit 14 outputs the search results of the setting history search unit 131. The storage unit 15 stores setting history information 1511, influence range identification rules 152, equipment information 153, and product information 154. These will be described later.

[0044] Next, the terminal device 2 and the control device 3 in the first embodiment will be described. First, FIG. 8 is a functional block diagram of the terminal device 2 in the first embodiment. The terminal device 2 has an input unit 21, an authentication unit 22, a setting unit 23, a communication unit 24, and a display unit 25. First, the input unit 21 accepts input regarding settings from an operator. This input indicates setting values ​​including at least "what," "how," and "reason" as items regarding meaning in the setting history. In addition, "who" and "when" may also be included in the setting values.

[0045] The authentication unit 22 also authenticates the operator who is the user of the terminal device 2. This authentication can be achieved by using an ID or password accepted by the input unit 21, an IC card, or biometric authentication. The setting unit 23 also notifies the control device 3 of the accepted setting values ​​via the communication unit 24. At this time, the setting unit 23 notifies the setting values ​​in association with their item names.

[0046] Furthermore, the communication unit 24 communicates with at least the control device 3. The communication unit 24 may be capable of communicating with the history information management device 1 and the management device 6. Furthermore, the terminal device 2 may be realized by a computer, and the functions of the authentication unit 22 and the setting unit 23 may be executed by a processor according to a program. Furthermore, the display unit 25 displays the contents of input to the terminal device 2 and the processing results. The input unit 21 and the display unit 25 may be realized by a single device such as a touch panel.

[0047] Next, the control device 3 will be described. Fig. 9 is a functional block diagram of the control device 3 in the first embodiment. The control device 3 has a timekeeping unit 31, a communication unit 32, a calculation unit 33, and a storage unit 34. First, the timekeeping unit 31 has a timer function for measuring time.

[0048] Furthermore, the communication unit 32 communicates with the history information management device 1, the terminal device 2, and the equipment 4. First, the communication unit 32 notifies the history information management device 1 of the setting history. Then, the terminal device 2 notifies the communication unit 32 of the setting value and the authentication result by the authentication unit 22. Furthermore, the communication unit 32 notifies the equipment 4 of a control command.

[0049] Furthermore, the calculation unit 33 executes various calculations in the control device 3. To this end, the calculation unit 33 has a control unit 331 and a setting management unit 332. The control unit 331 creates a control command for controlling the operation of the equipment 4. At this time, the control unit 331 creates the control command using setting history information 341, which will be described later.

[0050] Furthermore, the setting management unit 332 stores the setting values ​​received by the communication unit 32, the authentication results, and the times measured by the timer unit 31 in the storage unit 34 as setting history information 341. In particular, the setting management unit 332 stores the important setting history in a predetermined storage area of ​​the storage unit 34. For this reason, the storage unit 34 has multiple storage areas. Note that when the control device 3 is realized by a PLC, the calculation unit 33 can be executed by a processor following a program. The storage unit 34 also stores the setting history information 341 and the influence extent identification rule 342. The setting history information 341 and the influence extent identification rule 342 will be explained after the setting history information 1511.

[0051] This concludes the explanation of the functional block diagrams of each device in the first embodiment. Next, an implementation example of the history information management device 1 that executes the main processing in the first embodiment will be described. An example in which the history information management device 1 is realized by a server that executes processing according to a program will be described below. FIG. 10 is a configuration diagram showing an implementation example of the history information management device 1 in the first embodiment. Note that in FIG. 10, the history information management device 1 is shown with a management device 6 connected via a network 7, but the terminal device 2, control device 3, facility 4, and shared resource facility 5 are omitted.

[0052] In FIG. 10, the history information management device 1 has a processing device 101, a communication device 102, a main storage device 103, and a sub-storage device 104, which are connected to each other via a communication path.

[0053] Here, the processing device 101 can be realized by a processor such as a CPU, and executes calculations in accordance with a history information management program 105 described later. The communication device 102 has an interface function for connecting to the network 7, and corresponds to the input unit 11 and the output unit 14 in FIG.

[0054] Furthermore, the main storage device 103 can be realized by a so-called memory, and for the purposes of calculations in the processing device 101, a history information management program 105 stored in a storage medium such as a secondary storage device 104 and information used in the processing of this history information management program 105 are deployed. Furthermore, the secondary storage device 104 can be realized by a storage such as a hard disk drive, and stores programs and various information (such as setting history information 1511). In this way, the secondary storage device 104 corresponds to the storage unit 15 in FIG. 7.

[0055] 7. The history information management program 105 stored in the secondary storage device 104 is made up of a setting history collection module 106 and a setting history search module 107. The modules of the history information management program 105 have the following correspondence with the respective parts in FIG. Setting history collection unit 121: Setting history collection module 106 Setting history search unit 131: Setting history search module 107 That is, the processing device 101 executes the processes of the setting history collection unit 121 and the setting history search unit 131 in accordance with the history information management program 105 .

[0056] Furthermore, the history information management program 105 is distributed via the network 7 or stored in a storage medium and then installed in the history information management device 1. Each module may be configured as an independent program. The history information management device 1 may be realized as a production management device that manages a manufacturing system. In this case, the history information management program 105 may be realized as one function of the production management program.

[0057] The secondary storage device 104 also stores setting history information 1511, impact extent identification rules 152, equipment information 153, and product information 154 as information used in this embodiment. The secondary storage device 104 may be implemented as a device (e.g., a database system) separate from the history information management device 1. In this case, the setting history information 1511, impact extent identification rules 152, equipment information 153, and product information 154 may be shared or divided between the secondary storage device 104 of the history information management device 1 and the separate device. This concludes the description of the implementation example, but the history information management device 1 may also be implemented as a computer such as a PC or tablet having an input device and a display device. In this case, the input unit 11 corresponds to the input device, and the output unit 14 corresponds to the display device.

[0058] Furthermore, the history information management device 1 may be realized as a computer of a company that operates a manufacturing system, or may be realized as a computer of an information service company that provides services to multiple companies.

[0059] Next, the information in the first embodiment will be described. The influence range identification rule 152, the equipment information 153, and the product information 154 are the same as those in Fig. 2. However, these can be omitted. Therefore, first, the setting history information 1511 will be described, and then the setting history information 341 of the control device 3 will be described.

[0060] 11 is a diagram showing setting history information 1511 used in the first embodiment. The setting history information 1511 indicates a setting history and is information composed of meaningful plaintext data. Therefore, the setting history information 1511 has items such as a relevant related device, an item name, and a setting value. The relevant related devices include at least the terminal device 2 to which the setting information was input, and may also include related control devices 3, equipment 4, and shared resource equipment 5.

[0061] Furthermore, the item name indicates the name of an important item in the setting history, that is, its meaning. In the first embodiment, the item names used are "when," "who," "what," "how," and "reason." Here, "when" indicates the time of input. Furthermore, "who" indicates the entity that input the information, that is, the operator in the first embodiment. Furthermore, "what" indicates the equipment that is the target of setting and that operates by control according to the setting history. Furthermore, "how" indicates the content of the control or operation of the target equipment (what) by the setting. Furthermore, "reason" indicates the reason for the setting. Furthermore, a setting value indicating the content is recorded for each of these item names.

[0062] Next, FIG. 12 is a diagram showing setting history information 341 used in the first embodiment. The setting history information 341 is information showing setting history collected by the terminal device 2 and the control device 3. In the setting history information 341, each setting value of the setting history is recorded in each address (storage area). In the example of FIG. 12, the time is recorded in address 1, the operator who inputted it in address 2, the equipment to be set in address 3, the control and operation content due to the setting in address 4, the reason for the setting in address 5, and the temperature when the setting was input in address 6. Note that, as will be described in detail later, important setting history is recorded in addresses 1 to 5, and other (normal setting history) is recorded in addresses 6 and onward.

[0063] The setting history information 1511 is created by extracting important setting history from the setting history information 341. Therefore, as described above, normal setting history is also recorded in the setting history information 341. However, at the stage of creating the setting history information 341, important setting history may be selected and the information may be limited to this.

[0064] The influence extent identification rule 342 is information similar to the influence extent identification rule 152. Therefore, a description thereof will be omitted. However, compared to the influence extent identification rule 152, it is desirable to limit the influence extent identification rule 342 to rules relating to related devices related to the control device 3 that stores the influence extent identification rule 342. This concludes the description of the information used in the first embodiment, and next, a description will be given of the processing flow in the first embodiment. Fig. 13 is a flowchart showing the processing flow in the first embodiment. Each step in Fig. 13 will be described below, but the processing main body of the history information management device 1 mainly uses the configuration in Fig. 7.

[0065] First, in step S101, the input unit 21 of the terminal device 2 accepts a login input from an operator. At this time, authentication input such as an ID and password is accepted. Then, in step S102, the authentication unit 22 performs authentication processing on the login input of step S101. As a result, if authentication is not successful (NG), the process proceeds to step S103. On the other hand, if authentication is successful (OK), the process proceeds to step S104.

[0066] Furthermore, in step S103, the authentication unit 22 displays via the display unit 25 that authentication has failed. As a result, the operator can retry the login input. Furthermore, in step S104, the authentication unit 22 notifies the control device 3 via the communication unit 24 of identification information (ID) that identifies the operator based on the login input. Then, in step S105, the input unit 11 of the history information management device 1 accepts the notified ID. Note that the identification information may be encrypted when notified in step S104. Furthermore, the information notified between devices in each of the following embodiments and the information stored in the memory unit 15 may also be encrypted information.

[0067] Furthermore, in step S106, the input unit 11 accepts a menu selection from the operator on the menu selection screen displayed on the display unit 25. Here, it is assumed that the setting input menu is selected. Then, in step S107, the input unit 11 accepts an input from the operator of setting values ​​that the operator desires to update (register or change) for control or operation. For this purpose, the setting unit 23 causes the display unit 25 to display a setting value input screen 250 for inputting setting values. Then, as setting values, "what": the equipment to be set, "what": the content of control or operation by the setting, and "reason": the reason for the setting are input. These setting values ​​constitute an important setting history indicating important items. Here, these items are input into input areas provided on the display screen of the display unit 25 for inputting the respective items.

[0068] 14A and 14B, the setting value input screen 250 in the first embodiment will be described. In the first embodiment, the setting value input screen 250 is configured with a setting value input screen 250-a shown in Fig. 14A and a setting value input screen 250-b shown in Fig. 14B. Then, the setting value input screen 250-a transitions to the setting value input screen 250-b.

[0069] 14A, a setting value input screen 250-a is configured with a manufacturing process display area 251 and a related equipment input area 252. The target manufacturing process is displayed in the manufacturing process display area 251. The manufacturing process display area 251 may be displayed in response to an input from the operator via the input unit 21.

[0070] Furthermore, the related equipment input area 252 displays the equipment 4 and shared resource equipment 5 used in the manufacturing process display area 251 in association with the details of their control and operation. That is, the related equipment input area 252 displays "what" and "how" as options. In the example of FIG. 14A, "equipment 4-1" is displayed with "heating at 90 degrees" as its operation details. FIG. 14A also shows that "what" and "how" have been selected for 90 degrees of equipment 4-1 as the target for updating (inputting) the set value. In this way, upon receiving the selection of the related equipment and the details of its control and operation from the input unit 21, the setting unit 23 transitions the display from the set value input screen 250-a to the set value input screen 250-b.

[0071] 14B, the setting value input screen 250-b is made up of a manufacturing process display area 253, a related equipment display area 254, a control / operation content input area 255, and a reason input area 256. First, the manufacturing process display area 253, like the manufacturing process display area 251, displays the target manufacturing process.

[0072] The related equipment display area 254 displays the related equipment (equipment 4-1) selected on the setting value input screen 250-b. The control / operation content input area 255 is an area for inputting the control or operation content to be changed, and is composed of an area before change and an area after change. The value selected in the related equipment input area 252 is displayed before the change. After the change in the control / operation content input area 255, the value after the change input by the operator is displayed. In the example of FIG. 14B, the angle has been changed (from 90 degrees) to 100 degrees.

[0073] Furthermore, the reason input area 256 is an area for inputting the reason for the setting, that is, the "reason." In FIG. 14B, it is composed of a reason for selection input area 256-1 and a free reason input area 256-2. The reason for selection input area 256-1 lists options that are frequently used as "reasons." In addition, the free reason input area 256-2 is provided to deal with cases where there is no corresponding option in the reason for selection input area 256-1. In the free reason input area 256-2, characters indicating the reason can be entered in (Other). In the reason for selection input area 256-1 and the free reason input area 256-2, the color of the checkbox changes for the selected item. In FIG. 14B, (When changed) is selected to check the operation.

[0074] This concludes the description of the setting value input screen 250-a and the setting value input screen 250-b, but the setting value input screen 250 is not limited to this. For example, a single screen may display the setting value input screen 250-a and the setting value input screen 250-b. Furthermore, the input of the setting value is not limited to the above example, and may be unified into either selection or character input (free input). Selection input may be input by selection from a pull-down menu or the like. Furthermore, values ​​other than those described above may also be input as setting values. Furthermore, the setting value input screen 250-b may display the names of each item, such as "when," "who," "what," "how," and "reason." This allows the operator to more intuitively understand the setting values.

[0075] In step S108, the setting unit 23 determines whether the input setting value is within a predetermined range. This predetermined range can be defined as the performance range of the equipment 4, the range of product specifications, or the range permitted by regulations such as laws. If the result shows that the setting value is outside the range, the process proceeds to step S109. If the setting value is within the range, the process proceeds to step S110.

[0076] Furthermore, in step S109, the setting unit 23 displays via the display unit 25 that the input setting value is out of range. As a result, the operator can re-input the setting value. Furthermore, in step S110, the setting unit 23 notifies the control device 3 of the input setting value via the communication unit 24. At this time, the setting unit 23 assigns an item name to each input setting value. In other words, it is desirable for the setting unit 23 to assign "what," "how," and "reason" to each setting value. For this purpose, the setting unit 23 identifies the item name from the input area into which the setting value was input. Note that the method for identifying the item name is not limited to this method. For example, the setting unit 23 may determine the item name from the setting value.

[0077] Furthermore, in step S111, the communication unit 32 of the control device 3 receives the notified setting value. In response to this, in step S112, the setting management unit 332 determines whether the received setting value affects quality, etc. and is a predetermined important item. For this purpose, the setting management unit 332 uses the influence extent identification rule 342. That is, it determines whether the setting value satisfies the conditions of the influence extent identification rule 342. As a result, if the setting value does not have an influence or is not the above-mentioned important item (NO), the process proceeds to step S113. If the setting value does have an influence and is an important item (YES), the process proceeds to step S114.

[0078] In step S113, the setting management unit 332 writes the accepted setting value to any of addresses 6 and onward other than addresses 1 to 5 to which the important setting history is assigned. In this way, the setting management unit 332 stores the setting value in the storage unit 15.

[0079] Furthermore, in step S114, the setting management unit 332 identifies the ID and time corresponding to the accepted setting value (important item). To this end, the setting management unit 332 uses the timer unit 31 to identify and use the time when the setting value was accepted or the time of acceptance in step S105. Note that the time may be determined by adding the time when the terminal device 2 accepted the setting value (for example, as a timestamp). Furthermore, the setting management unit 332 identifies the ID accepted in step S105 as the ID corresponding to the setting value.

[0080] Then, in step S115, the setting management unit 332 converts the identified time, ID, and setting values ​​that are important items into plain text data and creates an important setting history. That is, an important setting history consisting of the items "when," "who," "what," "how," and "reason" is created. In response to this creation, in step S116, the setting management unit 332 writes each item of the important setting history to the corresponding address in the storage unit 34. That is, the setting management unit 332 writes "when" to address 1, "who" to address 2, "what" to address 3, "how" to address 4, and "reason" to address 5. In this way, the setting management unit 332 stores the important setting history in the storage unit 15. Furthermore, items that do not fall under the important setting history are written to addresses 6 and onward.

[0081] Through the above processing, the important setting history is stored as plaintext data in the control device 3. Then, in step S117, the setting history collection unit 121 of the history information management device 1 collects the important setting history from the multiple control devices 3 via the input unit 11. Furthermore, in step S18, the setting history collection unit 121 stores the collected important setting history in the storage unit 15 as setting history information 1511.

[0082] In step S117, the setting history collection unit 121 may also collect setting history information 341 that includes the normal setting history. In this case, in step S118, the setting history collection unit 121 extracts the normal setting history from the collected information. Then, the setting history collection unit 121 stores the important setting history and the normal setting history in the storage unit 15, distinguishing between them.

[0083] This concludes the description of the first embodiment, but the first embodiment is not limited to this. For example, in step S112, the determination of whether the setting value is within the range may be omitted. In this case, it is determined whether the received setting value is a predetermined important item.

[0084] Furthermore, at least a part of the processing of steps S112 to S115 may be executed by the setting unit 23 of the terminal device 2.

[0085] According to the first embodiment, it is possible to selectively store and manage more important setting histories. As a result, it is possible to sort out or reduce unnecessary information that may become noise from management information, and narrow down to useful information. As a result, it is possible to efficiently manage the quality control of products and the operation, alarms, maintenance, etc. of the equipment 4. [Example]

[0086] In the second embodiment, an example of searching the setting history information 1511 created in the first embodiment will be described. That is, the second embodiment is an example of using the setting history information 1511, which is plain text data (audit trail), which is an example of the collected manufacturing history information 151. Therefore, the configuration and information used in the second embodiment are the same as those in the first embodiment (see FIGS. 7 to 12). Therefore, a description of these will be omitted, and the processing flow of the second embodiment will be described below.

[0087] FIG. 15 is a flowchart showing a processing flow in the second embodiment. First, in step S201, the input unit of the management device 6 accepts a search request from an operator. Note that, before step S201, an authentication process similar to steps S101 to S103 may be executed. Also, in step S202, the search unit of the management device 6 causes the display unit to display a search screen. This search screen displays a search condition input area for each item of the important setting history. These items indicate "when," "who," "what," "how," and "reason." In other words, items that can become audit trails are displayed.

[0088] In step S203, the search unit accepts input of keywords on the search screen via the input unit 21. At this time, input for at least one item of the important setting history is accepted. In step S204, the search unit creates search conditions by combining the input keywords with corresponding items. Then, in step S205, the search unit notifies the management device 6 of the history search conditions via the communication unit.

[0089] Furthermore, in step S206, the input unit 11 of the history information management device 1 accepts the notified search conditions. Furthermore, in step S207, the setting history search unit 131 searches for setting history information 1511 using the search conditions. In step S206, if keywords for some items are set as search conditions, the setting history search unit 131 searches for setting history information 1511 that satisfies these. In this case, the search ignores the contents of other items, regardless of their content. Note that, as described above, since the setting history information 1511 is information that is specialized or centered on important setting history information, this search is performed with reduced noise. This enables a more efficient search.

[0090] Furthermore, in the first and second embodiments, setting history information 1511 is collected for a plurality of pieces of equipment 4. Therefore, it is possible to perform a search across a plurality of pieces of equipment 4, not limited to a specific piece of equipment 4. In particular, by using the lot ID or the product type ID of a product as a keyword for a search condition, it is possible to perform a search across a plurality of pieces of equipment 4. In this way, in the first and second embodiments, it is possible to optimize information management by standardizing the setting history information 1511, which is on-site data.

[0091] Furthermore, in step S208, the setting history search unit 131 notifies the management device 6 of the search results via the output unit 14. At this time, the setting history search unit 131 may calculate a search score for each piece of searched setting history information 1511, and notify the management device 6 of the search results sorted in this order.

[0092] In step S209, the communication unit of the management device 6 receives the notified search results. Then, in step S210, the search unit of the management device 6 displays the search results on the display unit. At this time, the search results can be sorted and displayed in order of search score.

[0093] This concludes the description of the second embodiment. According to this processing flow, it is possible to search for setting history information 1511 related to multiple related devices, regardless of the related devices such as the equipment 4 and the control device 3. Note that the second embodiment is not limited to this processing flow. For example, the processing of the management device 6 may be executed by the terminal device 2. Furthermore, regarding the search, instead of searching by keyword, the setting history search unit 131 may output a list of setting history information 1511 via the output unit 14 in response to a request from the management device 6. This is possible because the setting history information 1511 is limited in number because it is information specialized or centered on important setting history information. As a result, the setting history information 1511, which is a monitoring trail, can be visually confirmed. [Example]

[0094] In the first and second embodiments, setting history information 1511 is used as the manufacturing history information 151. In contrast, in the third embodiment, the manufacturing history information 151 is not limited to this, but is instead reflected in manufacturing management. In addition, when reflecting the manufacturing management, an influence range identification rule 152 is further used.

[0095] Below, we will explain an overview of a typical example of this manufacturing management, such as allocation management of shared resources and reflection of control on other manufacturing processes, with reference to FIG.

[0096] First, allocation management of shared resources will be explained. Take the example of shared resource equipment 5 as the related device in Figure 3. As shown in Figure 3, assume that cleaning of equipment 4-3 starts at 00:00. In this case, the remaining amount before cleaning is xxL, while the remaining amount after cleaning is managed as x1L, which is xxL minus the amount needed for cleaning. Furthermore, the remaining amount managed in this way is compared with the production schedule, and xxL of the shared resource required by equipment 4-N is allocated in advance. In this way, allocation management in Example 3 includes remaining amount management and allocation of shared resources. Note that the allocation itself may be omitted.

[0097] Next, the reflection of the information on other manufacturing processes will be described with reference to the records of the control device 3-1 and facility 4-1 of the related equipment in FIG. 3. As shown in FIG. 3, the operation (heating) of facility 4-1 starts 10 minutes late. Therefore, since the related equipment of the influence range identification rule 152 in FIG. 4 satisfies the operation conditions of facility 4-1, the start of preheating for the next manufacturing process 2 will be delayed. As described above, in the third embodiment, the manufacturing history indicated by the manufacturing history information 151 is reflected in manufacturing management using the influence range identification rule 152. Therefore, the influence range identification rule 152 can also be expressed as a manufacturing management rule. The third embodiment will be described in detail below.

[0098] First, Fig. 16 is a system configuration diagram showing a manufacturing system in Example 3. The following mainly describes the differences from Figs. 2 and 7. The basic functions of the devices constituting the manufacturing system in Example 2 are the same as those shown in Figs. 2 and 7. In particular, the terminal device 2, control device 3, equipment 4, and shared resource equipment 5 are the same as those shown in Figs. 2 and 7.

[0099] Therefore, the following describes a history information management device 1 according to a third embodiment. The history information management device 1 includes an input unit 11, a history information collection unit 12, an impact range identification unit 132, a manufacturing management unit 133, an output unit 14, and a storage unit 15. First, the input unit 11 receives manufacturing history information from related devices, as in Fig. 2. Also, the history information collection unit 12 collects manufacturing history information and operating statuses via the input unit 11, as in Fig. 2.

[0100] Furthermore, when manufacturing history information 151 about a certain facility 4 is collected, the impact extent identification unit 132 identifies the impact extent on the manufacturing system due to the manufacturing status indicated by this manufacturing history information. At this time, the impact extent identification unit 132 identifies the impact extent using impact extent identification rules 152. In the above example, the facility using the shared resource and the next manufacturing process that will be delayed are identified as the impact extent.

[0101] Furthermore, the production management unit 133 executes production management processing for production in the equipment included in the identified range of influence, according to the collected production history information 151. Examples of this production management processing include management of the remaining amount of shared resources, allocation, and control of the equipment 4 included in the range of influence (delaying preheating time). The range of influence identification unit 132 and the production management unit 133 are one aspect of the history information utilization unit 13 that utilizes the production history information 151.

[0102] Furthermore, the output unit 14 outputs the processing results of the manufacturing management unit 133, which is the history information utilization unit 13, and outputs instructions to collect manufacturing history information to related equipment in response to instructions from the history information collection unit 12. The processing results of the manufacturing management unit 133 include the remaining amount, whether or not allocation is possible, and control commands. The storage unit 15 stores manufacturing history information 151, impact extent identification rules 152, equipment information 153, and product information 154. These have been explained in the embodiment and Example 1, so their explanation will be omitted.

[0103] This concludes the explanation of the functional block diagram in the third embodiment, and next, an implementation example of the history information management device 1 that executes the main processing in the third embodiment will be explained. In the following, an example in which the history information management device 1 is realized by a server that executes processing according to a program, as in the first embodiment, will be explained. Then, the differences from the implementation example of the first embodiment (FIG. 10) will be mainly explained.

[0104] Fig. 17 is a configuration diagram showing an example of implementation of the history information management device 1 in Example 3. Note that Fig. 17 also shows the management device 6 connected to the history information management device 1 via a network 7, but does not show the terminal device 2, control device 3, facility 4, and shared resource facility 5. Furthermore, the history information management device 1 has a processing device 101, a communication device 102, a main memory device 103, and a secondary memory device 104, which are connected to each other via a communication path, just like Example 1.

[0105] Similarly to the first embodiment, the secondary storage device 104 stores a history information management program 105. However, the history information management program 105 includes a history information collection module 108, an impact extent identification module 109, and a manufacturing management module 110. These correspond to the history information collection unit 12, the impact extent identification unit 132, and the manufacturing management unit 133 in FIG. 16 , respectively. That is, the processing device 101 executes the processes of the history information collection unit 12, the impact extent identification unit 132, and the manufacturing management unit 133 in accordance with the history information management program 105. The secondary storage device 104 also stores manufacturing history information 151, impact extent identification rules 152, equipment information 153, and product information 154.

[0106] Next, a description will be given of a processing flow in the embodiment 3. Fig. 18 is a flowchart showing the processing flow in the embodiment 3. Each step in Fig. 18 will be described below, but the processing main body of the history information management device 1 mainly uses the configuration in Fig. 16.

[0107] First, in step S301, the history information collection unit 12 of the history information management device 1 collects the manufacturing history information 151 via the input unit 11. Then, in steps S302 and S303, the extent of the influence is identified. Then, in steps S304 and S305, manufacturing management is performed. Each step will be described below.

[0108] In step S302, the impact extent identification unit 132 searches for the impact extent identification rule 152 using the collected manufacturing history information 151. Furthermore, in step S303, the impact extent identification unit 132 uses the impact extent identification rule 152 to identify the impact extent, such as the manufacturing process and related equipment, which are based on the manufacturing history information 151. When the use of sterilized water stored in a shared resource storage facility, which is an example of shared resource facility 5, is collected as the manufacturing history information 151, the impact extent identification unit 132 identifies the maintenance process (all facilities), manufacturing process 3 (facility 4-3), and manufacturing process N (facility 4-N) as the impact extent.

[0109] In step S304, the production management unit 133 identifies the management process to be executed for the identified production process and related equipment. For example, if the start time of equipment 4-1 (production process 1) is delayed by +α, the production management unit 133 delays the residual heat release time of the next production process 2 (equipment 4-2) by x minutes. In addition, when sterilized water, a shared resource, is used, the production management unit 133 identifies whether to reduce the amount used from the remaining amount or to allocate it. "Allocation" means to secure sterilized water in advance, since a decrease in sterilized water makes it necessary to secure sterilized water early.

[0110] Then, in step S305, the production management unit 133 executes the identified management process. For example, the production management unit 133 creates a control command for the corresponding control device 3 and notifies it. This example includes the production management unit 133 issuing a control command to the control device 3 for the identified equipment 4 to delay the operation start time and notifying the control device 3 via the output unit 14. In other words, the production management unit 133 predicts the operation status of the equipment 4 and realizes control of other downstream equipment 4.

[0111] Furthermore, the manufacturing management unit 133 may record the control command in the equipment information 153 and the product information 154 .

[0112] The production management unit 133 may also calculate the remaining amount of sterilized water and allocate it to the relevant equipment 4 accordingly. In this example, the production management unit 133 performs management processing in accordance with the planned use time, which is included in the collected production history information 151. That is, the production management unit 133 manages the remaining amount of sterilized water for each period according to the planned use time. The production management unit 133 then allocates sterilized water in order so that the more upstream the production process, the higher the priority of sterilized water use. Alternatively, the production management unit 133 may allocate sterilized water preferentially to production processes of important products. Note that, as a shared resource allocation, the production management unit 133 may record the details of the allocation (planned use) in the production history information 151, as shown in FIG. 3, or may record the details of the allocation in the equipment information 153 or the product information 154.

[0113] As a result, the control device 3 of the third embodiment can more appropriately control the equipment 4 according to the operating status and settings of the manufacturing system. That is, each equipment 4 can execute a more appropriate manufacturing process, and the manufacturing system can be operated more efficiently.
