Abstract: To conduct qualitative and quantitative analysis of enterprise energy consumption, according to the concurrent, serial and regurgitation characteristics of enterprise energy consumption process with multi-set, multi-process and multi-stage, fuzzy extended Petri nets model oriented to enterprise energy consumption process was studied. Conflicts existing in the model were analyzed in depth and the conflicts resolving strategies were also discussed. Then, a solution to simulate the enterprise energy consumption process based on the presented model was proposed. Implementations of simulation model and simulation algorithm were given in detail. Simulation example showed that this method could simulate the dynamic behavior of enterprise energy consumption, and provided data of direct and indirect energy consumption for enterprises. It was a feasible way for enterprise energy efficiency evaluation.
