This paper presents a method based on timed Petri net (TPN) method that is used to program optimal JP for assembly shop. It includes three parts further. Firstly, an architecture of solutions to JP problems for any kind of shop oriented is presented to define a particular JP for a designated JP problem. Secondly, Petri net model is specified for aircraft part assembly processes. Finally, algorithms for optimizing generation of dynamic mechanism and a simulating case are then discussed. In comparison with traditional methods such as PERT or CPM, it is obviously convenient for planners or schedulers to schedule and manage assembly processes.展开更多
