Background

BOM is an object that describes the hierarchy of a product structure in a parent-child relationship. In various fields of product research and development, production, sales, service and the like, a product BOM is always a tie and a bridge for connection. In the life cycle of a product, BOM changes frequently occur due to a series of reasons such as quality improvement, customer demands, supplier changes and the like, and how to manage BOM changes becomes an important problem for a manufacturing enterprise to think.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The material change processing method provided by the application can be applied to an application environment shown in figure 1. There is provided a material management system as shown in fig. 1, including:

a processor 110 comprising a processor 1, wherein the processor 1 is configured to perform the above-described processing method for material change;

A business refers to a series of related activities that are necessary and logically related in enterprise management in order to accomplish a certain management function. Through system investigation, a general knowledge of the main business of the system can be made by knowing the organization structure and business functions, but the knowledge of the business thus obtained is static and mapped to the business by the organization department. Whereas the actual traffic is flowing, so that the "traffic flow" is also called a traffic flow. A complete business process involves multiple departments and multiple pieces of data. Data is a further abstraction and generalization of traffic in that it completely eliminates specific substances, leaving only the flow, processing and storage of data, and in that it can link various different traffic processes together to form a whole. In the technical scheme, the material management system can realize integrated transmission and unified management of data of the service flow and the data flow.

Further, the bill of materials management system 120 may refer to a system for managing a specific business process and content in any one of a demand, planning, designing, producing, distributing, running, using, repairing, maintaining, and disposing until recycling. Product lifecycle management system 130 may refer to a system that manages information and processes throughout a lifecycle of a product from a need, planning, design, production, distribution, operation, use, maintenance, until recycling for disposal. The bill of materials management system 120 cooperates with the product lifecycle management system 130 and integrally transmits the processed data information to the downstream resource management system 140 for storage, so as to be called at any time.

Further, a system architecture diagram of the material management system is provided as shown in fig. 2. Specifically, the bill of materials management system 120 may refer to a BOM change integrated management system for performing "business flow". The BOM is short for bill of materials, and is a technical document for describing the composition of products of enterprises. In the production management of computer-aided enterprises, first, a computer is required to read out the product constitution and all the materials to be involved of the enterprises, and in order to facilitate the recognition of the computers, the product structure expressed by the graphic must be converted into a data format, and the file describing the product structure in the data format is a bill of materials (BOM). BOM is a technical document that defines the structure of a product, and therefore, it is also known as a product structure table or product structure tree. The product lifecycle management system 130 may refer to a PLM system for performing "data streaming". The PLM system supports a series of application solutions of creation, management, distribution and application of information of the whole life cycle of a product, and is a management system capable of integrating human resources, processes, application systems and information related to the product. The resource management system may refer to an ERP system, which is configured to receive and store data transferred by the upstream BOM change integrated management system for calling, where EPR is an enterprise information management system that is mainly configured to perform integrated management of material resources, fund resources and information resources for the manufacturing industry.

Further, the user wants to initiate a material change request, firstly creates and edits a change order in the PLM system, and submits the change order after perfecting the change order according to the actual condition of material change. Secondly, a unified change approval process can be initiated in the PLM system, and after the process is initiated, the process automatically enters a data flow approval in the PLM system, namely, a change process corresponding to material change is generated. And meanwhile, automatically extracting detailed information of the change list, entering a BOM change integrated management system, and synchronously performing 'business flow' approval, namely generating an approval flow corresponding to the material change.

Further, the change flow generated by the PLM system comprises a design change node, an associated change check node, a design data release node, a process programming node and a process data release node, wherein the design data release comprises an uploading drawing list and a design drawing release, and the process data release comprises production technology execution, manufacturing data release, check programming and physical verification confirmation. The approval process generated by the BOM change integrated management system comprises a department approval node, a lead approval node, a design data release node, a process data release node and a verification planning and compiling node. When the approval process is executed to the manufacturing data release node, the BOM change integrated management system maintains the changed data, and the changed data is released to the ERP system in the form of manufacturing data after maintenance so as to call production management data.

Fig. 3 schematically shows a first flow diagram of a method of handling material changes according to an embodiment of the application. As shown in fig. 3, in an embodiment of the present application, a method for processing material change is provided, which is applied to the bill of materials changing system, and includes the following steps:

step 301, in the case that the product lifecycle management system generates a change flow for a change order to be processed, generating and executing an approval flow corresponding to the change order to be processed, where the change order to be processed includes material change information of a bill to be changed, the change flow includes a design change node, an associated change check node, a design data issue node, a process programming node, and a process data issue node that are sequentially executed conditionally, the approval flow includes a department approval node, a lead approval node, a design data issue node, a process data issue node, and a check programming node that are sequentially executed conditionally, any node in the change flow or the approval flow corresponds to a series of task execution logics, and the product lifecycle management system is configured to allow the change flow to be executed to the design data issue node when it is detected that the change flow passes through the associated change check node and the approval flow also passes through the lead approval node.

Step 302, allowing the approval process to be executed to the process data issuing node when the verification of the change process at the design data issuing node is detected and the approval process is also detected.

And step 303, when the approval process is detected to pass the verification of the process data issuing node, issuing a to-be-processed change list acquired from the product life cycle management system to the resource management system so that the resource management system can complete the change operation of the to-be-changed bill of materials based on the material change information.

If a user initiates a material change request, material change contents are filled in through a carrier material change list in a product life cycle management system. The material change can be new, deleted and modified, in the product life cycle management system, the material change list can comprise five important plates of new revision components, new technology revision components and structural change information, and a user can select the data information of the corresponding important plate perfecting change list according to the specific condition of the material change. For example, after the user selects to design new revised components and designs new components, the material change grade, material handling scheme and material change detail of the material change bill are perfected according to the changed actual conditions. In the technical scheme, the material change grades can be divided into three grades of I, II and III, wherein the I grade material change is set to be required by a company leader for checking and approving, the II grade material change is set to be required by a technical branching leader for checking and approving, and the III grade change is set to be required by a project responsible person for checking and approving. The material handling scheme is that after a user adds a material code of a material to be handled, a product life cycle management system can call a system interface of a resource management system according to input content to acquire inventory information of five ways of changing the material in a purchasing plan, a complete machine making, a company inventory, a complete machine inventory and a factory complete machine, and the user can give reasonable handling scheme suggestions for the inventory in different places according to the information.

Further, after the user perfects the material change list and submits the material change list, the product life cycle management system can generate a corresponding change flow according to the change list to be processed submitted by the user. And the processor extracts the change details in the change list to be processed under the condition that the change flow generated by the product life cycle management system is detected, so that an approval flow corresponding to the change list to be processed is generated, and the approval flow is executed. Specifically, the modification flow includes a design modification node, an associated modification check node, a design data distribution node, a process programming node, and a process data distribution node that are sequentially conditionally executed. The approval process comprises department approval nodes, lead approval nodes, design data release nodes, process data release nodes and inspection planning and compiling nodes which are sequentially and conditionally executed, and any node in the change process or approval process corresponds to a series of task execution logic. Conditional execution may mean that each node can enter and execute the node after a predetermined rule is satisfied before executing the node. For example, the entry rules of node a include rule B and rule C, and flow is allowed to enter node a only if both rule B and rule C are satisfied. Specifically, in the technical scheme, the product life cycle management system is used for allowing the modification process to be executed to the design data release node under the condition that the modification process is detected to pass the verification of the associated modification check node and the approval process is detected to pass the verification of the leading approval node. Specifically, the design data release node in the change flow includes two preconditions, the condition one is that the associated change check node in the change flow is checked and passed, the condition two is that the leading approval flow in the approval flow is checked and passed, and the change flow can enter the design data release node only if the condition one and the condition two are satisfied.

Further, the processor allows the approval process to be executed to the process data distribution node if the change process is detected to pass the verification at the design data distribution node and the approval process is detected to pass the verification at the design data distribution node. And the processor issues the to-be-processed change list acquired from the product life cycle management system to the resource management system under the condition that the approval process passes the examination and approval of the process data issuing node, so that the resource management system completes the change operation of the to-be-changed bill of materials based on the material change information.

By the technical scheme, unified management of the material changing process and the result is realized.

FIG. 2 is a flow chart of a method for handling material changes in an embodiment. It should be understood that, although the steps in the flowchart of fig. 2 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 2 may include multiple sub-steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor do the order in which the sub-steps or stages are performed necessarily performed in sequence, but may be performed alternately or alternately with at least a portion of the sub-steps or stages of other steps or other steps.

In one embodiment, the product lifecycle management system 130, after automatically entering the "data flow," can alter the flow state of the flow, including any of to-be-generated, in-design, in-process, to-be-manufactured, and the processor can synchronize the flow state of the altered flow into the processor. Specifically, the processor identifies the flow state of the change flow, so that the user can intuitively know the real-time progress of the current material change, after the user initiates the change in the product life cycle management system 130, the timing scheduling task of the system extracts the change related information, the flow state is "to be generated" at this time, and then the approval flow initiated automatically through timing scheduling enters the state of "in design". When the system flow reaches the design data release node, the design release mark of the change bill is scanned regularly, and after the mark is identified, the state in the system is changed from "in design" to "in process". When the process flow in the product life cycle management system 130 reaches the process data release node, the process release identifier of the change list is scanned regularly, and after the identifier is identified, the state in the product life cycle management system 130 is changed from process in process to process. When the process of the product lifecycle management system 130 reaches the "manufacturing data release" node, the state of the ERP system is periodically scanned and changed from "to be manufactured" to "in manufacturing" when the material change order is successfully transferred from the product lifecycle management system 130 to the resource management system 140.

Further, the product lifecycle management system 130 executes the process to the design data distribution node, the change order enters a "design distribution" state, and after the processor obtains the state, the approval process is allowed to enter the design data distribution node. Specifically, under the condition that the approval process is executed to the design data release node, an uploading drawing list node and a design drawing release node are generated and executed in sequence, after a drawing list uploaded by the uploading drawing list node is acquired, the uploading drawing list node is allowed to pass through, and the design drawing release node is executed. And after the completion of the transmission of the drawing list is detected, allowing the design drawing issuing node to pass through. And under the condition that the verification of the issuing node of the design drawing is detected to pass, determining that the verification of the changing flow at the issuing node of the design data passes. Specifically, after the PLM system 'unified change flow' is initiated, the processor automatically generates a business approval flow, and the business approval flow is respectively checked by a professional director, each department can be signed (for example, the signing of a plan, an electric, a hydraulic, a mechanical, a process, a quality and an authentication department can be included), three-level lead auditing (for example, the lead auditing of a project principal auditing, a technical branching lead auditing (III level change is not needed) and a company lead auditing (II and III level change is not needed) can be included), then the processor enters a 'design data release' node, and the approval node is automatically passed through after the PLM system design data is released, the process data release node and the drawing list uploading node are entered, and after the drawing list is uploaded by a change initiator, a drawing management specialist can transfer changed drawings at the 'design issue' node.

In one embodiment, the processor issues the pending change order obtained from the product lifecycle management system 130 to the resource management system 140 upon detecting that the approval process passes at the process data issue node, so that the resource management system 140 completes the change operation of the to-be-changed bill of materials based on the bill of materials change information. Specifically, the processor may determine that the change in the material has been completed by simply uploading the material change order to the downstream resource management system 140 for validation. When the approval process is at the process data release node, the processor generates a production plan execution node and a manufacturing data release node, and then obtains design and process data released in the product life cycle system, wherein the design and process data comprises the manufacturing type of the changed materials. The processor allows execution of the production plan execution node if it detects that the manufacturing type is the same as the initial manufacturing type before the material change is not made. Specifically, when the design and process data issued in the product lifecycle management system 130 after the process data is issued are completely entered, the processor first identifies whether the manufacturing type of the changed material is changed, if so, the processor needs to maintain and complete the main data of the related material according to the data field requirement of the resource management system 140, and if not, the process data is not affected, and enters a "production plan execution" node, so as to require the production planner to set the change order effective time and the host switching number and time in the resource management system 140 for the production execution system to call on time.

Further, after setting the production plan, the node enters the "manufacturing data distribution" node, and the production manager transmits the change data to the resource management system 140, and after successful transmission, the node automatically passes through. Specifically, when the production manager sends the change data to the resource management system 140, the processor needs to obtain the effective time of the change list of the material to be processed. When the production plan executing node passes the verification, the manufacturing data issuing node can be executed, and when the validation time is reached, the pending change list is determined to be validated, and the validated pending change list is issued to the resource management system 140, so that the resource management system 140 completes the change operation of the to-be-changed bill of materials based on the bill of materials change information. Or after the effective time of the material change list to be processed is obtained, the material change list to be processed is issued to the resource management system 140, and under the condition that the effective time is reached, the resource management system 140 completes the change operation of the material list to be changed based on the material change information. Specifically, the following two ways may be selected to include: first, the resource management system 140 takes effect immediately when the change data is ready to take effect and is clicked and sent from the processor, and second, the change effective time value is defined by the resource management, and then the change effective time value is transmitted to the resource management system 140, and the resource management system 140 is provided with a set of own programs and can take effect after waiting for the defined effective time, so that the rhythms of production are not disturbed. The post-processor of the process data release can enter the branch node of the test, the test planning and the real object test confirmation, and the quality manager can confirm whether the change acts on the production on time or not and evaluate the influence of the change on the real object.

In one embodiment, the product lifecycle management system 130 can also be configured to allow execution of the change flow to a process orchestration node if it is detected that the change flow is passing through the design data distribution node, where the process orchestration node includes a master process orchestration node, a professional process orchestration node, and a process engineering approval node that are sequentially conditionally executed. Specifically, after the product life cycle management system 130 completes the design data release and change process, the process compiling and process approval node is automatically entered, and under this node, the product life cycle management system 130 mainly checks that the data in two aspects includes: in the first aspect, whether the material change flow performed by a non-owner under the material change order reaches the 'associated change check' node is checked. In the second aspect, checking whether the lead approval is completed, reaching a node of 'design data release', and if both checking rules are satisfied, allowing the design data to enter a release state and reach a node of 'hosting process compilation'. And under the condition that the process approval node is detected to pass, determining that the process programming node passes the approval. Under the condition that the change flow is executed to the associated change check node, detecting whether the user to which a plurality of materials in the bill of materials to be changed belong is the same as the initiating user of the change flow; and allowing the change flow to pass through the associated change check node under the condition that all the belonging users of the materials are the same as the initiating user of the change flow.

Further, for the first aspect, it is checked whether the material change flow performed by the non-owner under the material change order has all reached the "associated change check" node, because a situation that one or more materials are included in one material change order, that is, a situation that a plurality of users merge the material change order exists, when one user initiates the material change order, the creator of the non-change order, that is, the other users, can directly refer to the change order when performing the design change, so as to achieve the effect of "take" change. Therefore, in the case where the material change order includes a plurality of materials, and the plurality of materials are each created by the same user, the associated change check node is allowed to pass.

Further, when the processor detects that a plurality of materials in the to-be-processed material change list are initiated by different users, firstly determining target users different from the initiating user of the change flow in the users to which the plurality of materials belong, and secondly inquiring whether each target user initiates the associated change flow aiming at the to-be-processed change list. And under the condition that each target user initiates the associated change flow, detecting whether each associated change flow is executed to a change check node, and under the condition that each associated change flow is executed to the change check node, allowing the change flow to pass through the associated change check node. And under the condition that at least one associated change flow is not executed to the change check node, the change flow is not allowed to pass through the associated change check node until all the associated change flows are executed to the change check node. Specifically, when the material change list includes a plurality of materials and the plurality of materials are created by different users, it is necessary to detect the current states of the other plurality of materials different from the user to which the material initiator belongs, and detect that the other plurality of materials are also independently initiated by the initiator corresponding to the material initiator, and if the state of the process also reaches the current association change check node, the association change check node of the process is allowed to pass. Specifically, for example, assuming that three change materials 01, 02 and 03 exist under the change order a, the change initiator creates the materials 01 and 02, and the other person creates the materials 03, when the change order a initiates the "unified change flow", all the materials of the creator not the change order initiator are checked, in this example, 03, and if the change 03 does not initiate the "unified change", the change a will initiate the "unified change" failure. If the material 03 does not reach the node when the node of the change list A is in the 'associated change check', the change list A is not allowed to pass the node of the 'associated change check'.

By the technical scheme, unified management of the material changing process and the result is realized. The method comprises the steps of organically integrating data flow of a PLM system and business flow of an original OA system, perfecting a structured change list after the PLM system prepares change materials, initiating a model change flow, automatically extracting relevant data in the structured change list by a BOM change integrated management system after initiation, automatically initiating a business approval flow in the BOM change integrated management system to start business approval, enabling the PLM system to release design change data before approval by relevant responsible persons in the business approval, automatically passing through corresponding nodes after design/process data release in the PLM system, simultaneously realizing manufacturing data transmission downstream ERP system by the BOM change integrated management system, and automatically passing through the corresponding nodes after transmission, thereby realizing integrated management of product life cycle BOM change. The technical scheme has the advantages that the whole process of changing from research and development to production and manufacturing is integrated uniformly, intelligent synchronization of the changing process is realized, the integrated data transmission of changed business flow and data flow is realized, the changing business is smoother, the structuring of changing details is realized, the efficient transmission of the changing details is realized, the setting of changing effective time is realized, the changing is ensured to be effective on time, the production is timely acted, the whole process of the technical scheme is driven, and the data safety and timeliness are ensured.

Fig. 4 schematically shows a first flow diagram of a method of handling material changes according to an embodiment of the application. As shown in fig. 4, in an embodiment of the present application, a material change processing method is provided, which is applied to the product life cycle management system 130, and includes the following steps:

step 401, obtaining a to-be-processed change order initiated for material change.

Step 402, generating a change flow according to the change list to be processed.

Step 403, extracting and sending the material change information in the change list to be processed to the bill of material change system 120, so that the bill of material change system 120 generates and executes an approval process corresponding to the material change information; the change flow comprises a design change node, an associated change check node, a design data release node, a process compiling node, a process approval node and a process data release node which are sequentially executed conditionally, the approval flow comprises a department approval node, a lead approval node, a design data release node, a process data release node and a check planning compiling node which are sequentially executed conditionally, any node in the change flow or the approval flow corresponds to a series of task execution logic, and the change flow is allowed to be executed to the design data release node under the condition that the change flow is detected to pass the examination of the associated change check node and the approval flow is also checked to pass the lead approval node.

Step 404, allowing the modification process to be executed to the process data issuing node when the modification process is detected to be at the process data issuing node and the approval process is checked to pass at the design data issuing node.

Step 405, when it is detected that the approval process passes at the process data issuing node, the material change information is issued to the resource management system 140 through the material list change system 120, so that the resource management system 140 completes the change of the material list to be changed based on the material change information.

And the user initiates a material change request, and selects the data information of the corresponding key plate perfecting change list according to the specific condition of material change. After the user perfects the material change list and submits the material change list, a unified approval change flow is initiated, and the processor can generate a corresponding change flow aiming at the change list to be processed submitted by the user. In the case that the processor generates the change flow, the material change information in the change list to be processed is extracted to the bill of material change system 120, and the bill of material change system 120 generates an approval flow corresponding to the change list to be processed and executes the approval flow. Specifically, the modification flow includes a design modification node, an associated modification check node, a design data distribution node, a process programming node, and a process data distribution node that are sequentially conditionally executed. The approval process comprises department approval nodes, lead approval nodes, design data release nodes, process data release nodes and inspection planning and compiling nodes which are sequentially and conditionally executed, and any node in the change process or approval process corresponds to a series of task execution logic. Conditional execution may mean that each node can enter and execute the node after a predetermined rule is satisfied before executing the node. For example, the entry rules of node a include rule B and rule C, and flow is allowed to enter node a only if both rule B and rule C are satisfied. Specifically, in the technical scheme, the processor allows the change flow to be executed to the design data release node under the condition that the change flow is detected to pass the verification of the associated change check node and the approval flow is detected to pass the verification of the leading approval node. Specifically, the design data release node in the change flow includes two preconditions, the condition one is that the associated change check node in the change flow is checked and passed, the condition two is that the leading approval flow in the approval flow is checked and passed, and the change flow can enter the design data release node only if the condition one and the condition two are satisfied.

Further, the processor allows the approval process to be executed to the process data distribution node if the change process is detected to pass the verification at the design data distribution node and the approval process is detected to pass the verification at the design data distribution node. The processor issues the material change information to the resource management system 140 through the bill of material system under the condition that the approval process passes through the process data issuing node verification, so that the resource management system 140 completes the change operation of the bill of material to be changed based on the material change information.

In one embodiment, the processor allows execution of the change flow to the process orchestration node upon detecting that the change flow is passing through the design data distribution node, where the processor primarily examines data in two aspects including: in the first aspect, whether the material change flow performed by a non-owner under the material change order reaches the 'associated change check' node is checked. In the second aspect, checking whether the lead approval is completed, reaching a node of 'design data release', and if both checking rules are satisfied, allowing the design data to enter a release state and reach a node of 'hosting process compilation'. After the process programming node is detected to pass the verification, and under the condition that the change flow is executed to the associated change check node, detecting whether the user to which a plurality of materials in the bill of materials to be changed belong is the same as the initiating user of the change flow. And allowing the change flow to pass through the associated change check node under the condition that all the belonging users of the materials are the same as the initiating user of the change flow.

Fig. 5 schematically shows a first flow diagram of a method of handling material changes according to an embodiment of the application. As shown in fig. 5, in an embodiment of the present application, a material changing processing method is provided, which is applied to the above material management system, and includes the following steps:

step 501, the product lifecycle management system 130 obtains a to-be-processed change order initiated for material change, and generates a change flow according to the to-be-processed change order, where the change flow includes a design change node, an association change check node, a design data issue node, a process programming node, a process approval node, and a process data issue node that are sequentially executed conditionally.

Step 502, the product life cycle management system 130 extracts and sends the material change information in the change list to be processed to the bill of materials change system 120.

In step 503, the bill of materials changing system 120 generates and executes an approval process corresponding to the bill of materials changing information according to the bill of materials changing information, where the approval process includes a department approval node, a lead approval node, a design data release node, a process data release node, and a check planning node that are sequentially executed conditionally, and any node in the change process or the approval process corresponds to a series of task execution logic.

In step 504, when the product lifecycle management system 130 detects that the modification process passes the verification of the associated modification check node and the approval process passes the verification of the leading approval node, the modification process is controlled to be executed to the design data publishing node.

In step 505, when the bill of materials changing system 120 detects that the changing process passes the verification of the design data issue node, the verification process is controlled to be executed to the design data issue node.

In step 506, when the product lifecycle management system 130 detects that the modification process is at the process data distribution node and the approval process passes the verification of the design data distribution node, the modification process is controlled to be performed to the process data distribution node.

In step 507, when the bill of materials changing system 120 detects that the changing process passes the process data issuing node, the approval process is controlled to be executed to the process data issuing node.

In step 508, when the bill of materials changing system 120 detects that the approval process passes through the process data issuing node, the bill of materials changing information is issued to the resource management system 140, so that the resource management system 140 completes the changing operation of the bill of materials to be changed based on the bill of materials changing information.

As shown in fig. 2, the materials management system includes a product lifecycle management system 130 for executing the data flows, a bill of materials management system for executing the service flows, and a resource management system 140 for storing the changed materials data. The user wants to initiate a material change request by first creating relevant material change information through a carrier material change order in the product lifecycle management system 130. After the user perfects the change list according to the actual condition of material change, submitting the change list. Secondly, a "unified change approval process" can be initiated in the product lifecycle management system 130, and after the process is initiated, the product lifecycle management system 130 can obtain a to-be-processed change order initiated for material change, and generate a change process according to the to-be-processed change order. Specifically, the data stream approval is entered automatically. The change flow comprises a design change node, an associated change check node, a design data release node, a process compiling node, a process approval node and a process data release node which are sequentially and conditionally executed.

Further, the product life cycle management system 130 generates the change flow, and the processor extracts and sends the material change information in the change list to be processed to the bill of material change system 120, and the bill of material change system 120 can generate and execute the approval flow corresponding to the material change information according to the material change information. The approval process comprises department approval nodes, lead approval nodes, design data release nodes, process data release nodes and inspection planning and compiling nodes which are sequentially and conditionally executed, and any node in the change process or approval process corresponds to a series of task execution logic.

Further, in the case where the product lifecycle management system 130 detects that the modification process passes the associated modification check node and the approval process passes the lead approval node, the modification process is controlled to be executed to the design data distribution node. The bill of materials change system 120 automatically generates a business approval process after the product lifecycle management system 130 initiates the "unified change process", which respectively provides the professional director with a check, each department with a signature, three-level leadership audit, and company leadership audit. In the product lifecycle management system 130, the "unified change flow" is initiated and then "data flow" approval is performed, and the product lifecycle management system 130 sequentially enables the user to go through the nodes of design compilation, verification, design verification, process verification, standardized verification and approval, and then the bill of materials management system enters the node of "associated change verification". For this node, the product lifecycle management system 130 checks the two-way data: on the other hand, whether all material change flows performed by non-owners under the change list reach the 'associated change verification' nodes is checked, mainly because the situation of merging the change list exists, namely, a creator of the non-change list directly refers to the change list when performing design change, and the 'taking' change effect is realized. For this case, the product lifecycle management system 130 requires that the designer who opens and closes the change order initiate a "unified change procedure" before the change initiator, and at the same time, check whether all the sub-components in the change order reach the "associated change check" node at the "associated change check" node, if not, alert the change procedure initiator in the form of reporting errors, and not allow the sub-components to pass through the node, and only when all the sub-components reach the node, the sub-components can take effect when clicking the node. On the other hand, whether the three-level lead approval in the bill of materials management system is finished or not can be checked, and the node of 'design data release' is reached. When clicking the node passing the 'associated change check', the processor will call the current flow state of the change list to be processed in the bill of material management system once. If the processor detects that the bill of materials management system has reached the "design data issue" node, it determines that all three levels of leaders in the approval process have completed approval, waiting for the design data issue in the product lifecycle management system 130. If the processor detects that both verification rules are satisfied, the approval process in the product lifecycle management system 130 may be allowed to pass through the node, the design data enters the release state, and the modification process reaches the "hosting process compilation" node. Specifically, in the product lifecycle management system 130, when the modification process is at the "master process creation" node, the master process engineer will assign a manufacturing type to the modified design data, such as converting from self-made (self-made) to out-of-order (external vendor assisted), and then assign a professional process creation task to the professional process engineer, enter the "professional process creation" node, and the professional process engineer performs a specific professional process creation in the product lifecycle management system 130. After professional process programming is completed, a professional artist initiates a process work change approval process in the system of the product life cycle management system 130, the product life cycle management system 130 performs release operation on process data after programming, checking and approval, the professional artist can automatically release a change list object through the professional process programming node in the unified change process through the post-product life cycle management system 130, and the product life cycle management system 130 changes the approval process. After the product lifecycle management system 130 alters the release of the single object, the bill of materials alteration system 120 automatically passes through the "process data release" node.

Further, in the case where the bill of materials change system 120 detects that the change flow passes the verification at the design data issue node, the verification flow is controlled to be executed to the design data issue node. At this time, the bill of materials management system will enter the "design data issue" node, wait for the product life cycle management system 130 to issue the design data and then automatically pass through the approval node, enter the "process data issue" node and upload drawing bill node, and the drawing management staff will transmit the changed drawing at the "design drawing issue" node after the initiator uploads the drawing bill.

Further, in the case where the product lifecycle management system 130 detects that the modification process is at the process data distribution node and the approval process passes the verification of the design data distribution node, the modification process is controlled to be performed to the process data distribution node. In the event that the bill of materials change system 120 detects that the change process passes the process data issue node audit, the approval process is controlled to be executed to the process data issue node. The design and process data published in the product lifecycle management system 130 after the process data is published has been completely entered into the bill of materials modification system 120. The bill of materials changing system 120 first identifies whether the manufacturing type of the changed materials changes, if so, the main data of the related materials need to be maintained according to the data field of the resource management system 140, and if not, the main data is not affected, and then the bill of materials changing system enters into a "production plan executing" node, so as to require the production planner to set the effective time of the change list and the host switching number and time in the resource management system 140 for the production execution system to call on time. After setting the production plan, the node enters a "manufacturing data distribution" node, and the production manager transmits the change data to the resource management system 140, and after successful transmission, the node automatically passes through.

Further, in the case that the bill of materials changing system 120 detects that the approval process passes through the process data issuing node, the bill of materials changing information is issued to the resource management system 140, so that the resource management system 140 completes the changing operation of the bill of materials to be changed based on the bill of materials changing information. There are two ways in which change data may be sent to resource management system 140: one is to wait until the change data is ready to take effect and click and send from the system, the resource management system 140 takes effect immediately; the other is that the value of the effective time is defined by the system and then transmitted to the resource management system 140, and the resource management system 140 has a set of own programs and can wait until the defined effective time to be effective, thereby ensuring that the self-rhythm of production is not disturbed.
