摘　　要：为解决传统单目标优化方法难以满足导弹总体参数多目标优化的需求,以及多学科设计优化方法复杂而难于在导弹概念设计阶段使用的问题。提出了一种基于变权TOPSIS(逼近于理想排序)评价和粒子群算法融合的多属性综合优化设计方法。以标准粒子群优化算法为基础,运用变权综合原理构建变权状态变量,结合TOPSIS评价方法计算每组粒子(总体参数方案)的可行欧氏距离,以欧氏距离作为综合评价目标开展了导弹总体参数优化设计研究工作。经实例分析表明,基于变权TOPSIS的粒子群优化设计方法能够有效解决导弹概念设计阶段总体设计多参数、多属性综合优化问题,与传统设计方法相比,具有概念清晰、方法灵活、实现高效的优点。It is difficult to meet the multi-objective optimization of the missile＇s overall parameters for the traditional single-objective optimization method,whereas the multidisciplinary design optimization method is complicated and difficult to be used in the concept of missile design stage.In order to solve this problem,a multi attribute evaluation method on the basis of variable weight synthesis Technique for Order Preference by Similarity to Ideal Solution（ TOPSIS） and the principle of particle swarm algorithm fusion are introduced.Based on the standard particle swarm optimization algorithm,the variable weight state variables were constructed by using the variable weight synthesis principle,and calculation of the feasible Euclidean distance of each group of particles（ the overall parameter scheme） is conducted with TOPSIS evaluation method.The Euclidean distance is taken as the comprehensive evaluation target to overall parameter optimization design research work.The results show that the particle swarm optimization design method based on variable weight synthesis TOPSIS can effectively solve the problem of multi-parameter and multi-attribute optimization in the conceptual design stage of the missiles.Compared with the traditional design method,it has several advantages such as clear concept,flexible method and high efficiency.
