摘要：
Aiming at the problem of the redundancy investment of the material in the production enterprise of circular economy zone, the timed-Petri net model is established for the material flow element module based on the timed-Petri net and simulation technology. Firstly, the expression of the time sequence and the dependence of the material flow system are expressed; And then, using mathematical algorithms to quantify the material optimal investment amount and the optimal investment time of the cycle of material flow system through the analysis of the model; Finally, take a Saline Lake enterprise in Qinghai Province as an example, the using of the timed-Petri net model can improve the efficiency of the material utilization greatly through the empirical analysis of the case. The optimal algorithm is suitable for small and medium sized circular economy enterprise, but it is of significance for small and medium enterprises facing the problem of "cycle but diseconomy". © 2016, Editorial Board of Journal of Systems Engineering Society of China.
