A study on performance evaluation of computer systems using Petri Nets

Abstract

This paper describes performance evaluation of Real-time system using Petri net. Two types of Petri nets Stochastic Petri net (SPN) and Generalized Stochastic Petri net(GSPN) are discussed and a comparative study the two variants of Petri net has been proposed. This comparison will give an insight on the use of Generalized Stochastic Petri net over Stochastic Petri net. An example of a parallel system modelled using SPN and GSPN is used to analyze the comparison between SPN and GSPN. A case study from manufacturing industry that belongs to the class of pull strategies Just-in-Time is considered to explore the flexibility of GSPN in modeling and analysis of a Real-time system. Open source software PIPE is used to model and analyze SPN and GSPN for performance evaluation of Real-Time system.
