Abstract:The paper modeled the energy emergency management processes based on generalized stochastic Petri nets. With the invariants the author determined the validity of the model, obtained state-space reachability graph and isomorphic Markov chain. Then through analyzing the steady-state probability the author analyzed the performance of the system. Simulating the case that the energy shortage emergency management process from November 2009 to January 2010, the author obtained the stable state probability. Based on that the author calculated the average number of markers library and token utilization. The results showed that emergency response and emergency recovery are the bottleneck of emergency management energy. Manager and decision-maker should emphasize on them in order to improve energy emergency efficiency.
