Performance analysis based on generalized stochastic Petri net
Lei G · Journal of Beijing Information Science & Technology University · 2013
The application of Petri net theory to the field of performance evaluation is studied. Based on the generalized stochastic Petri nets and its analysis technique,utilization of the GSPN on system modeling and performance analysis is discussed. To solve the problem of throughput and resource utilization in typical dual processor system,a GSPN model of dual processor system is established,using isomorphic relations between stochastic Petri net and Markov chain. The stable state space of GSPN model and probability of each status are gained. Then the dual processor performance metrics such as throughput and utilization of the system are analyzed. Through the TimeNet simulation experiment tool, the validity of the established model is proved,which provides related basis for the throughput and availability improvement.
