摘要
为充分利用产品三维模型与仿真数据,客观评价可选装配序列,提出一种基于区间逆序数和逼近理想解法的装配序列综合评价方法。建立了包含零件级和系统级指标的装配序列综合评价指标体系,针对零件级指标引入区间逆序数方法进行定量化评价,同时定义了各个系统级指标的定量化方法。采用逼近理想解法方法综合评价候选装配序列,确定最佳序列。以某航天产品某部件的三种装配序列为例,验证了该方法的有效性和实用性。
To make full use of 3D model and simulating data, a comprehensive evaluation approach based on interval inverse number and Technique for Order Preference by Similarity to Ideal Solution （TOPSIS） was proposed. A hier- archical evaluation index system composed of part-level and system-level was presented. The interval inverse number method was introduced to evaluate part-level indices quantitatively. Meanwhile, a quantitative evaluation method for system-level indices was proposed. The candidate assembly sequences were ranked by TOPSIS, and the best se- quence was confirmed. An example of aerospace product assembly sequences evaluation was presented to illustrate the feasibility of the proposed approach.
