Optimization methods of the product assembly line system

The assembly line can be regarded as a system consisted of complex disperse events considering the assembly process exists not only time sequence relations but also parallel and competitive relation. This article investigates the methods of modeling the product assembly line system based on information of assembly process flow, combined with the requirement that the auto electrical machine assembly should be adopted to multi-production, and the materiel flow and information flow change complicatedly in product assembly line, the system model of auto electrical machine assembly line is set up based on Petri net. The structure configurations and dynamic properties of the system are investigated by intuitionistic graphics format using Petri net. The operation performance of the system through reachability method is analyzed to optimize the system ensuring the key actions and the pivotal resources. Heuristic scheduling arithmetic is put forward and the emulation results are presented, the auto electrical machine assembly line recombining construction and optimization is achieved. The methods proved to be feasible and effective through the practice run of the product line.
