Model simplification in Petri net models

Abstract

Model simplification is a methodology to reduce size and complexity of models, e.g. by moving some of the details away from the model and into the model implementation code. This paper talks about supporting Petri net model simplification in a new tool for modeling and simulation of discrete event dynamic systems. Firstly, this paper presents a brief introduction to model abstraction and model simplification. Secondly, this paper presents a brief introduction to the new tool known as GPenSIM. Thirdly, through a case study, this work shows how model simplification can be done in GPenSIM and also how effective or useful model simplification can be.
