Amulticriteria decision-makingmodel was proposed in order to acquire the optimumone among different product design schemes.\r\nVIKOR method was introduced to compute the ranking value of each scheme. A multiobjective optimization model for criteria\r\nweight was established. In this model, projection pursuit method was employed to identify a criteria weight set which could\r\nkeep classification information of original schemes to the greatest extent, while PROMETHEE II was adopted to keep sorting\r\ninformation. Dominance basedmultiobjective simulated annealing algorithm (D-MOSA) was introduced to solve the optimization\r\nmodel. Finally, an example was taken to demonstrate the feasibility and efficiency of this model.
