摘要: 为了提高复杂产品的装配序列规划效率,利用蚁群算法的并行性及其搜索过程的独立性,对装配序列进行异步并行求解。首先,调整产品结构树的装配层次关系,并基于多色集合理论(PST)对装配层次结构进行形式化表达,建立PS层次结构树;其次,基于“分治”原则,建立“全局并行、区域线性”的蚂蚁搜索策略,对PS层次结构树进行逐层规划和整合计算,实现装配序列的异步并行求解,并提高求解效率;然后,为了解决非线性装配序列表达方式问题,建立装配序列树模型及其自相关矩阵。最后,通过实例验证了异步并行装配序列方法的可行性与有效性。

Abstract: In order to improve the efficiency of complex product assembly sequence planning, using the parallelism of ant colony algorithm and the independence of its search process to solve assembly sequence by parallel asynchronous method. Firstly,the assembly hierarchy of the product structure tree is adjusted, and the PS hierarchy tree is established in order to formally express the hierarchy tree based on the polychromatic set theory. Secondly, the search strategy of ant colony algorithm which is "global parallel, local linear" is established based on the principle of "divide and conquer", and the PS hierarchy tree is layer by layer planned and integration calculated in order to complete parallel asynchronous solution for assembly sequence and improve solving efficiency. And then, assembly sequence tree model and its self-correlation matrix are established to meet the requirement of nonlinear assembly sequence expression. Finally, the feasibility and effectiveness of asynchronous parallel assembly sequence planning is verified by a typical case.

Key words: ant colony algorithm, assembly sequence, assembly sequence tree model, asynchronous parallel planning, PS hierarchy tree
