Conceptual design scheme automatic generation and decision-making considering green demand

Abstract

Conceptual design is a key stage of product design. In order to make the design scheme have better greenness, this paper studies the automatic generation and decision-making technology of green demand-driven design. This paper mainly starts from the green demand of the conceptual design stage of electromechanical products, considers the introduction of green attributes into the product design information model, and builds an effective design space for electromechanical products. I This paper proposes an effective method for the low efficiency of current design schemes. The search strategy finally uses the genetic algorithm to complete the automatic generation of the design scheme. Considering the ambiguity and uncertainty of the design information, the LCA evaluation model based on the green feature is established, and the life cycle evaluation of the electromechanical products is completed. The effectiveness of the method is verified by an example of a car lift.
