Abstract: To realize fast process planning for automobile final assembly, a process planning method was presented based on the combination of zone/layer method for automobile final assembly task generation and largest set rule for task distribution. Firstly, based on the analysis of the assembly relationships among different parts, a zone/layer model of the whole automobile was established, which formed as a tree in the form of "part layer zone automobile". The parts were searched from the tree, and then the assembly tasks were generated and the priorities of the tasks were defined. Secondly, the task sequence within every zone was determined by largest set rule and the tasks were distributed into different sub-stations. Finally, the sequence of the sub-station of different zone was adjusted under production resources constraints. Based on this planning method, a computer-aided process planning system for automobile final assembly was developed so that the fast and automated process planning was realized.

Key words: final assembly process planning, zone/layer method
