基于合作博弈理论的汽车概念设计优化方法

将质量功能展开(QFD)与合作博弈理论相结合,提出一种汽车产品顾客满意度和成本优化设计的新方法.该方法主要包括:通过市场调查和QFD分析,获取顾客需求并转化为技术需求,建立顾客满意度水平评价模型;再通过确定博弈方、博弈效用和博弈策略分组,将顾客满意度和成本的多目标优化问题转化为合作博弈理论模型;然后采用联盟博弈的Shapley值法求解最优值.最后,通过某汽车车门开发示例计算与传统方法进行对比,验证了本文所提出方法的有效性.

Optimization Method for Vehicle Concept Design Based on Cooperative Game Theory

Abstract： Based on the QFD method and cooperative game theory, a new vehicle conceptual optimization design method for cost and customer satisfaction was proposed. First, the requirements of customers gained via market investigation were converted into technical requirements by QFD analysis, and a customer satisfaction index model was built. Second, by identifying the players and the payoff functions and grouping the players’ strategies, the multi objective optimization problem of the new product design was converted into the cooperative game theory model. Subsequently, the Shapley value method of coalitional gaming was used to calculate the optimized solution. Finally, the result obtained with the Shapley value method and that with the traditional methods were compared, and the effectiveness of the proposed method was verified.
