摘　　要：现有计算机辅助选择装配理论中只有针对单一装配尺寸链的选配模型,提出基于多装配尺寸链的选配模型,将计算机辅助选择装配转化为多目标优化问题,新模型为各装配尺寸链提供了权值和修正值。采用遗传模拟退火优化算法求解,最后通过事例分析该模型的效率与可行性。A selective assembly model based on multi-assembly dimensional chain is presented, whereas at present there only exists selective assembly model of single-assembly dimensional chain in computer aided selective assembly theory. The weight and revised value of the assembly dimensional chain are provided in the model solved by the genetic-simulated annealing algorithm, at last, the efficiency and the feasibility of the model are analyzed by instances.
