Abstract: To reduce the influence of subjectivity and individual decision making difference on car styling design decision making,a kind of car styling design decision-making model based on Multi-objective Particle Swarm Optimization(MPSO) algorithm was proposed.Through restricting the factors such as decision space and decision variables numbers of vehicle design,the multi-objective decision making problem was solved with MPSO algorithm,and the hierarchical iteration was adopted to optimize the final scheme of styling design.To achieve the simulation for the whole car styling design decision making process,the car design decision problem was mapped to the mathematical model for guiding the car designers to carry out innovative design and assist decision-makers to evaluate every scheme of different round in a rational manner.The design decision process of a compact SUV vehicle modeling program was taken as an example to prove the feasibility and rationality of the proposed model.

Key words: product design, car styling, design decision-making, design process, multi-objective particle swarm optimization, analytic hierarchy process

摘要： 为降低主观性和个体决策差异对汽车造型设计方案决策的影响,提出一种基于多目标粒子群优化算法的汽车造型设计决策模型,该模型通过限定汽车造型设计决策约束空间、决策变量的数量等因素,利用多目标粒子群优化算法对设计方案进行多目标决策,并采用层级分析法选取汽车造型设计最终(优)方案,将汽车造型设计决策问题映射到数学模型,来完成对整个汽车造型设计方案决策过程的模拟,引导汽车设计师有条理地进行创新设计,并辅助决策者各轮次的方案评价。以某紧凑型SUV汽车造型方案的设计决策为例验证了模型的可行性和合理性。
