Abstract: To analyze and evaluate the energy consumption of continuous enterprise more accurately,the new modeling method for continuous enterprise energy consumption process with uncertain factors was proposed.Based on the analysis for influence characteristics of the various uncertain factors,the triangular fuzzy number was combined with hybrid Petri nets effectively,and the relationship between uncertain factors was described by the triangular fuzzy number complementary judgment matrix.Furthermore,the calculation method for the instantaneous firing speed of energy consuming device was put forward,and the evolution rules and dynamic properties were also analyzed.The production process of the flake solid ionic membrane caustic soda was used as a case study to verify the feasibility and practicality of the proposed modeling method,which could not only reflect the influences of uncertain factors on the equipment performance,but also actually describe the energy consumption process of continuous enterprise.

Key words: energy consumption, uncertain factors, triangular fuzzy number, process modeling
