Embodiment Construction

[0046] Step 1.1, constructing a process-oriented product structure tree, which includes product structure composition information and production process information; for example image 3 As shown, the process-oriented product structure tree Antenna products are composed of structural subsystems, radio frequency subsystems, and servo control subsystems. The structural subsystems involve reflective surfaces, central bodies, support frames, and antenna bases. The reflective surfaces are divided into main reflective surfaces. , sub-reflecting surface, and reinforcing ribs; the central body is divided into a central ring and a central cylinder; the supporting back frame is divided into a radiation beam, a ring beam and an auxiliary beam.

[0047] Step 1.2, establishing a process library template for each node process of the product structure tree, so that the process library template is mapped to the product structure tree. Such as image 3 Each node of the antenna product structu...

Abstract

The invention relates to the field of computer product supported collaborative design, in particular to a product structure tree-based design flow dynamic modeling method. The method is characterized by at least comprising the following steps: 1.1, constructing a flow oriented product structure tree which contains structure composition information and design flow information of a product; 1.2, establishing a product design flow base template to complete mapping of the flow base template and the product structure tree; 1.3, determining whether or not the flow base template contains flow frame nodes or abstract nodes, entering step 1.6 if so, otherwise entering step 1.4; 1.4, directly generating flow instances by the nodes; 1.5 finishing and obtaining flow template design flow instances; 1.6, generating instances of the frame nodes or the abstract nodes by combining the product structure information; 1.7, adding the generated instances into the corresponding frame nodes and abstract nodes in the flow base template; and 1.8, returning to the step 1.3. In the product designing process, types of components and parts of the product structure tree and the composition information of the product structure tree are extracted in real time, and a dynamic work flow model of the whole machine of the product can be established through algorithm by combining an established component and part work flow template base.

Description

technical field [0001] The invention relates to the field of computer aided collaborative design of products, in particular to a dynamic modeling method of design process based on product structure tree. Background technique [0002] An important research direction in the field of collaborative design is process collaboration, and workflow technology is the core of process collaboration. Through workflow technology, it is possible to manage and coordinate the tasks, relationships between tasks, task status, resources, personnel and messages of an engineering project involving multiple people in an orderly manner, avoiding work confusion and confusion caused by lack of communication. rework. [0003] One of the key points of workflow technology is to establish workflow. Currently, there are two main ways to establish workflow: (1) Manual establishment, that is, to establish work tasks and their associated relationships through manual methods. (2) Automatic establishment bas...
