Research And Application Of Workflow-based Engineering Change Control Model In PLM System

Product Lifecycle Management(PLM)is a business strategy that uses computer software as a tool to help companies achieve informationalization,integrating the various components that businesses and their customers need.Most enterprises begin to choose to deploy PLM system to help enterprises improve product design and quality control,in order to enhance the core competitiveness of enterprises.The PLM system covers most of the data and processes of all product designs of the company.As PLM system functions and business processes continue to become complex and meticulous,business processes are facing with restructuring,processing reconfiguration,and data is changed to adapt to business and market requirements.With many changes,the application of Engineering Change Control(ECC)based on the product lifecycle management system is an essential business function in the day-to-day operations of manufacturing companies.Effectively use the underlying support of product lifecycle management system,data management,workflow management,etc.,to achieve personnel change,data and process change in the project change control,and version management of the workflow process instance before the entire process change,the entire change control is Completed under the workflow-driven.This article takes the background of the PLM system of the auto parts manufacturing industry independently designed and developed by the laboratory,and analyzes and designs the engineering change control of an auto parts manufacturing industry in detail.The specific implementation process mainly through the following steps: First,the study of engineering change control is analyzed to obtain the actual needs;secondly,the theoretical basis for engineering change in the PLM system is described,including workflow version management introduction and engineering change control model.Proposal;then make detailed design of workflow-based engineering change control,set the workflow operating mechanism and workflowengine driving principle in PLM system,and make version management of the changed workflow instance.Easy to find and use in the follow-up work,process design in the process of engineering change control,further analyze the operator and corresponding permission settings of each link in the engineering change control;finally select an appropriate development platform and database,and build a reasonable database structure and System-related functional class design,and analysis of the relationship between various functional classes,implementation on the project's PLM system,effective control of engineering change application,engineering change review,and engineering changes during engineering change control Execute the process to reduce engineering changes at The scope of influence between departments ensures the consistency of data caused by process changes and execution unit changes,ensures the standardization and security of data in engineering change control,and effectively improves the daily management of existing PLM systems in current parts and components companies.In the efficiency.
