Abstract Aiming at the complexity of the facilities scheduling in the aircraft assembly process, a new method to
build equipment scheduling model based on extended Petri net is proposed. The definition process and modeling methods
of this model are discussed by considering the characteristics of aircraft assembly process. The model is based on the objectoriented
Petri net to express the aircraft assembly process, which is related to the auxiliary equipment by timed Petri net,
and it is optimized by the hybrid algorithm with the time and equipment utilization. The fuselage assembly process of a certain
airliner is taken as an example to build the model and dispatch, and the experimental results show that the method has
great guiding significance to the actual assembly equipment scheduling.
