【Abstract】 In this paper, a specific algorithm for assembly sequence planning is described. The main merit of the algorithm is the combination of the assembly unit cutset and hierarchical unit division. The assembly sequence priority rules are set up to decide assembly directions according to assembly features. Finally, a binary tree model that describes both the assembly structure and the assembly process is generated recursively.更多还原
