摘要
装配序列生成是计算机辅助装配工艺规划（ＣＡＡＰＰ，ＣｏｍｐｕｔｅｒＡｉｄｅｄＡｓｓｅｍｂｌｙＰｒｏｃｅｓｓＰｌａａｎｉｎｇ）的关键环节。本文首先给出了基于特征产品装配模型，然后提出基于割集理论的装配序列自动生成算法。该算法根据评价准则采用ＡＯ搜索算法寻找最优的装配序列，既节省了装配成本和时间，又减少了算法的时间和空间复杂性。
Assembly sequence generation is a key link of the chain of CAAPP(Computer Aided Assembly Process Planning). In this paper, a feature-based assembly model is proposed, firstly. Then, the method of automatic generating assembly sequences is present- ed, which is based on the theory of cut-sets. According to the evaluating criteria, the optimal assembly can be found by use of AO. search algorithm, meanwhile, the complexity of space and time is reduced.
