Petri net optimization technology of intelligent assembly line for complex process timing

The assembly technology of large-scale manufacturing industry has become the main factor restricting the production efficiency and cycle. Combined with the development of industrial intelligent manufacturing, the product assembly line has gradually carried out digital, flexible and automatic design.In this paper, for the complex process timing of product assembly, the layout optimization design of intelligent assembly line is carried out based on Petri net technology.By analyzing the assembly test process, the composition of intelligent assembly line and production environment, considering the priority and resource conflict of multi tasks and operations, the simulation analysis of virtual production process is carried out to determine the bottleneck process and transformable links, and the supporting quantity and layout of automation equipment are optimized with the comprehensive goal of lean production and cost reduction.
