【摘要】 针对概念设计中方案设计的组合优化问题,如何避免组合爆炸、快速有效地产生一些可行方案的难题,提出多模糊集代数和定理以及模糊集比较定理,根据产品功能与功能载体、功能载体与功能载体之间的相互关系,利用模糊集理论建立了产品模糊矩阵和模糊多目标优化数学模型,并根据免疫细胞进化原理提出一种有效的多目标免疫优化算法。以带式输送机的传动方案设计为例进行验证,试验结果显示这种方法能够快速产生可行方案集,实现方案的自动化设计。更多还原

【Abstract】 Scheme design is the key process of conceptual design.Because scheme design is a combination optimization problem,it is difficult that how to avoid combination explore to produce some feasible schemes.The model of conceptual de- sign is built from the point of views of fuzzy multi-objective optimization.The theorem of multi-fuzzy-set algebra sum and the theorem of fuzzy set compare are presented,and then ac- cording to the relationships between structures and functions of the production,the fuzzy mathematical model of the multi-objective optimization of conceptual design is provided. In order to solve the multi-objective optimization question,an effective multi-objective optimal algorithm based on the evolu- tions of the immune cells,whose convergence and diversity are better than SPEA.An example of transmission scheme design of the belt conveyor is given to show that this method is able to produce the feasible schemes set and realize the automatic scheme design.更多还原
