Abstract

The invention provides a system for integrating product design and environment influence evaluation in a CAD system environment. The system comprises a product model importing module which imports a target product model from a CAD system, a product life cycle integrated modeling module which performs characteristic-based product state-process operation modeling to realize life cycle data integrated management, a product environment influence analysis module which is connected with the product life cycle integrated modeling module and performs product life cycle evaluation to generate an environment influence quantitative analysis result, and a product environment influence analysis result output module which is connected with the product environment influence analysis module and displays an environment influence analysis result in multiple forms. Meanwhile, the invention provides an integrating method of the integrating system. According to the system and method, integrated management of product design information and process design information is realized, product concurrent development is supported, and product design and development efficiency is improved; and integration of product design and environment influence evaluation is favorable for design and development of environment-friendly products.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a feature-based product design and life cycle assessment (LCA) integration system and method for a computer-aided design (ComputerAided Design, CAD) system. Background technique [0002] With the deteriorating environmental problems and the increasingly stringent relevant environmental laws and regulations, the environmental impact of products has become an important issue that users are increasingly concerned about and manufacturers must consider. The design stage is a key stage in the entire product development process, and it is also a key stage to prevent product environmental problems from the source. How to predict the environmental problems related to the product's entire life cycle at the product design stage and propose effective design measures has become a technical problem in product design and development under the new situation. [0003] At present, the m...
