FIG. 1 is a schematic diagram of a manufacturing process management system according to an embodiment of the invention. Referring to fig. 1, the manufacturing flow management system 100 includes a processor 110 and a storage device 120. The processor 110 is coupled to a storage device 120. The storage device 120 is used for storing a plurality of modules. In the embodiment, the processor 110 is configured to execute a plurality of modules, and the plurality of modules include a process planning module 121, a workshop management module 122, and a process management module 123. The user may operate the application interface of the manufacturing process management system 100 to select the knowledge blocks corresponding to the product/industry category and input the input data into the manufacturing process management system 100, and the manufacturing process management system 100 may automatically establish the related workshop process according to the input data and execute the vehicle monitoring management module 122 and the process control management module 123 to perform the control and management of the workshop process.

In the present embodiment, the manufacturing process management system 100 may be, for example, disposed in a computing device of a workstation for operation by a user. The workstations may be used to control multiple process tools and multiple workstations may achieve a single production goal. Alternatively, the manufacturing process management system 100 may be disposed in a cloud server, for example, for a user to operate, and control the workstation in parallel. In the present embodiment, the Processor 110 may include, for example, a Central Processing Unit (CPU), or other Programmable general purpose or special purpose Microprocessor (Microprocessor), Digital Signal Processor (DSP), Application Specific Integrated Circuit (ASIC), Programmable Logic Device (PLD), other similar Processing Circuits, or a combination thereof. The storage device 120 may include a Memory (Memory) and/or a database (database), wherein the Memory may be, for example, a Non-Volatile Memory (NVM). The storage module 120 may store relevant programs, modules, systems or algorithms for implementing the embodiments of the present invention, so as to be accessed and executed by the processor 110 to implement the relevant functions and operations described in the embodiments of the present invention. In the present embodiment, the advanced planning and scheduling system 121 and the manufacturing execution system 122 can be implemented by a program Language such as json (javascript Object notification), Extensible Markup Language (XML), YAML, or the like, but the invention is not limited thereto.

In this embodiment, the processor 110 may execute the process planning module 121 to generate a plant process associated with an industry category, and the processor 110 may execute the plant control module 122 and the process control module 123 to control operations of a plurality of process stations in the plant process. In this way, the manufacturing process management system 100 and the manufacturing process management method can efficiently establish a workshop process according to the requirements of the user and the knowledge blocks selected by the user. The processor 110 may automatically control the operation of the shop Workstation (WS) and the work in process manufacturing operation according to the data of the management project.

FIG. 2 is a flow chart of a manufacturing process management method according to an embodiment of the invention. Referring to fig. 1 and 2, the manufacturing process management system 100 of the present embodiment can perform the following steps S210 to S240. In step S210, the processor 110 inputs the input data to the flow planning module 121. In this embodiment, the user may input the input data through an application program interface of the manufacturing process management system 100. In this embodiment, the input data includes a plurality of knowledge blocks, and the knowledge blocks are respectively composed of at least one of associated industry categories, industry manufacturing processes, industry knowledge, logic rules, management and control targets, personnel management and control items, machine management and control items, material management and control items, manufacturing management and control items, personnel data, material data, and/or machine data. That is, the industry category and the management and control items related to personnel, equipment, materials and control rules can be used as input data.

In one embodiment, when the flow planning module 121 determines that the personnel data, the material data, and/or the tool data are less than or not in compliance with the threshold value of the logic rule, the flow planning module 121 adjusts the workshop flow. That is, the workshop process generated by the process planning module 121 is in accordance with the current personnel status, machine status, on-site material inventory, and production method of each workshop.

In step S220, the processor 110 may execute the flow planning module 121 to enable the flow planning module 121 to generate the workshop flow. The plant flow includes a plurality of process stations. In step S230, the processor 110 inputs the output data of the plurality of process stations to the plant control module 122, so that the plant control module 122 generates a determination result. In the embodiment, the plant control module 122 receives the control project data in the output data, and the plant control module 122 generates the determination result according to the logic rule. The judgment result is generated according to whether the output data of each process station in the workshop flow conforms to the default logic rule or not. It should be noted that, the user can input and set the logic rule and the control item through the application program interface as the input data.

In step S240, the processor 110 inputs the determination result to the process control module 123, so that the process control module 123 controls the operations of the plurality of process stations according to the determination result. Thus, the manufacturing process management system 100 can efficiently generate a corresponding workshop process according to the input and setting of the user.

FIG. 3 is a diagram illustrating an implementation of a manufacturing process management system according to an embodiment of the present invention. Refer to fig. 1 and 3. In this embodiment, the storage device 120 of the manufacturing process management system 100 may store a plurality of plant processes and default knowledge blocks associated with industry categories for user selection. That is, the user can conveniently click on the industry/industry level to further obtain the management target options (e.g., management items such as production lots, production lots and chips, production lots and cassettes, etc.) and the industry posting functions (e.g., posting items such as maintenance, batching, pooling, routing inspection, packaging, etc.).

In this way, the manufacturing process management system 100 encapsulates the industry knowledge into the knowledge blocks, so that the manufacturing process management system 100 can quickly generate the corresponding workshop process according to the knowledge blocks selected by the user, thereby highly reusing the industry knowledge and improving the efficiency of establishing and adjusting the workstation process. It should be noted that by encapsulating industry knowledge into knowledge blocks, the manufacturing process management system 100 can be swapped out and changed according to knowledge blocks selected by different users to flexibly and quickly establish new workshop processes in a manner that workshop processes are formed through the knowledge blocks. In this way, the manufacturing process management system 100 can flexibly and dynamically configure knowledge building blocks (industry knowledge) to greatly reduce the time required for the secondary development of software codes, so that different workshop processes can be efficiently established, and the establishment efficiency and adjustment efficiency of the workshop processes can be improved.

In the present embodiment, the manufacturing process management system 100 can perform the following steps S310-S380 to generate the shop floor process 390 and perform the operation control and management of the shop floor process and the workstations. In step S310, the processor 110 may execute the process planning module 121 to establish a process site context input/operation/output process according to the industry type of the input data. In this embodiment, the input data may include knowledge blocks, field personnel information, machine state information, field material resource information, and workshop production operation methods. It is noted that the knowledge block may include reference production planning information as well as reference reporting data information. The process site scenario input/operation/output flow may be, for example, a flow of inbound management and control, operation processing, and outbound management and control in each process site. That is, the flow planning module 121 establishes a plurality of process stations according to the knowledge blocks, and establishes the control flow of input, operation and output of each process station according to the logic rule.

In step S320, the flow planning module 121 configures a management and control project of the process site according to the knowledge blocks and the information of the process site. In this embodiment, the control project data includes at least one of personnel control project data, machine control project data, material control project data, and manufacturing control project data. In this way, the flow planning module 121 configures the management and control items of each process site according to the information of the process sites. That is, the flow planning module 121 configures different control items according to different process sites, for example, the control items of the plant process site that require personnel to operate include personnel control items, and the personnel control items may be, for example, personnel production and reporting, personnel status management, personnel authority control, and personnel utilization information. The equipment management and control items can be, for example, equipment operation report and status, module fixture life management, and equipment abnormality management and control. The material management and control items may be, for example, inquiry of material usage in production lot, management of material availability, material exception management, material usage return, and the like. The manufacturing management and control items may be, for example, collection of production parameters, industry knowledge management, production mode management, and machine parameter management.

In step S330, the process planning module 121 concatenates the flows of the process stations to form a production shop flow 390. It should be noted that the process flow of the process station is the scenario input/operation/output flow of each process station. In this embodiment, the flow planning module 121 connects the flows of the process stations in series to form a plant flow 390.

In step S340, the processor 110 inputs the output data of each process site 391 to 395 of the plant process 390 corresponding to the control project to the plant control module 122, so that the plant control module 122 collects the control project data. In step S350, the plant control module 122 generates a determination result according to the logic rule.

In step S360, when the control item data conforms to the preset or user-inputted logic rule, the workshop control module 122 outputs the determination conforming result (determination result) to the process control module 123, so that the process control module 123 executes the next process site operation in the plurality of process sites.

In step S370, when the control item data does not conform to the preset or user-inputted logic rule, the workshop control module 122 outputs the determination result (determination result) to the process control module 123, so that the process control module 123 executes the abnormal start-up processing. In the embodiment, when any of the managed items does not meet the threshold of the logic rule (e.g., yield), the flow control module 123 executes the corresponding process according to the information and settings of the current process station.

In one embodiment, the current process site is a process site 02 (e.g., an In-Circuit-Test (ICT)/Functional Test (FT) Test or a quality check) In the plant process 390, and the process control module controls the plant process to execute the process site 04 (e.g., a repair workstation) if the control items of the process site 02 do not meet the threshold values of the logic rules. In step S380, the process control module 123 inputs the output data generated by the process stations (e.g., the process station 04 and the process station 05) executed after the exception is initiated to the shop control module 122 to repeatedly execute step S340, so as to ensure that the output data (e.g., the yield) of the current process station meets the threshold of the logic rule.

In another embodiment, the exception opening process is that the process control module 123 executes the current process station again to generate the second control data, and the process control module 123 inputs the second control data to the plant control module 122 to execute step S340 again.

It should be noted that the logic rules include an inbound rule, and the plant control module 122 determines whether the current output data of the plurality of process stations conforms to the inbound rule. When the process control module 123 conforms to the inbound rule according to the current output data, the process control module 123 controls the workshop process 390 to continue to execute the operation of the current process station. That is, the logic rule also includes an inbound/outbound rule for each process site, so the shop control module 122 determines whether the inbound/outbound flow of the current process site conforms to the default logic rule of the user. In one embodiment, when the outbound rule indicates that the yield rate is 8, the shop control module 122 will ensure that the yield rate of the products produced by the current process station is 8, and then the outbound process will be performed. In this way, the manufacturing process management system 100 not only ensures that the overall plant process conforms to the logic rule, but also ensures that the input/output data of each process site conforms to the inbound/outbound setting value, thereby improving the stability of the manufactured product and the execution efficiency of the plant process.

In one embodiment, the logic rules include a carrier rule, and the plant control module 122 determines whether the carrier is reported to generate carrier data, so that the process control module 123 controls the operation of the current process station in the plant process according to the carrier data. In the present embodiment, the current process station is configured with an automatic carrier, so the flow planning module 121 is configured with a flow for detecting that a carrier arrives at the station and that the carrier is installed in the situation input/operation/output flow of the current process station. In this way, when the workshop controller 122 collects the carrier position data or the carrier arrival data (step S340), and the workshop controller 122 determines that the carrier arrives according to the carrier data and outputs the determination result to the process controller 123 (step S350). Thus, the process control module 123 controls the workshop process to execute the next process of the current process site (e.g., executing the process of loading the carrier and performing operations) according to the carrier-to-site information, so as to provide the multi-oriented and multi-functional manufacturing process management system 100 for the user. In this way, the manufacturing process management system 100 of the embodiment can establish a corresponding workshop process according to the input data and the knowledge blocks, and can provide the workshop process and the operation of each process site in the workshop process according to the preset rules according to the field personnel, the machine and the material factors, so as to improve the reusability of the industry knowledge, the establishment efficiency of the workshop process and the stability of the manufacturing process.

To sum up, the manufacturing process management system 100 and the manufacturing process management method of the present invention can generate the plant process 390 according to the input data including the knowledge blocks, and control the operation of the plant process 390 and the process stations in the plant process 390 according to the logic rules and the control items. In this way, the manufacturing process management system 100 can perform good operations and process creation on the workstations according to the related logic rules and the field data, and can effectively improve the process creation efficiency and the production efficiency of each workstation.
