Aiming at the problem of long processing time and low process efficiency in the outbound system of parts,a new method of constructing workflow Petri net model based on parallelization was proposed.A parallel Petri net model was constructed for the part outbound system.P-invariant was used to analyze the time performance.And the results of the correlation matrix,the time analysis of P-invariant and the parallel optimization algorithm were used to optimize the Petri net of the system.Therefore,the working time of the parts outbound system was improved.Verified by example,The parallel structure algorithm based on Petri net workflow is feasible in improving the system processing time.
