Full-life-cycle management method and system for engineering change in PDM system

Abstract

The invention relates to the field of product data management, and provides a product design process problem full-life-cycle management method and system. The method comprises the steps: obtaining technical parameters in customer demand information, and decomposing the technical parameters of a product into a node data set of product design; establishing a constraint rule set and rule priorities among the product technical parameters; establishing constraint relationship in the design process nodes and between the nodes; when an engineering change form is created in the PDM system, sending theengineering change form to an approval node, and sending the approval form generated after approval is passed and the engineering change form to an engineering change process node; and adjusting a subsequent design flow node module. According to the method, engineering changes and technical parameters can be changed, the association between the nodes is realized before the product design activityis started, and once the engineering change occurs, the repeated communication required by the data change generated by the engineering change is reduced, the full-life-cycle management of the automatic information change and the engineering change is realized, and the product collaborative design efficiency is further improved.

Description

Technical field [0001] The invention relates to the field of product data management, and in particular to a method and system for managing the entire life cycle of engineering changes in a PDM system. Background technique [0002] The PDM system (Product Data Management, PDM) manages all product-related information, including part information, configuration, documentation, CAD files, structure, authority information, etc., as well as all product-related processes, including process definition and management. Enterprises implement PDM System management can improve production efficiency, help manage the entire life cycle of products, strengthen the efficient use of documents, drawings, and data, standardize work processes, and have a wide range of applications in the process of enterprise product data management. [0003] CN106471503B discloses a method for product data management, which is executed by a data processing system and includes: receiving a CAD model, the CAD model inclu...
