Developing a Tool for Modeling and Simulation of Discrete Systems using Iterative Approach.

General-purpose Petri Net Simulator (GPenSIM) is a new tool for modelling and simulating discrete systems. GPenSIM was developed using the Iterative Approach, which divides the software development life-cycle into smaller tasks. In each iteration, we add more functionality. However, GPenSIM was created to model industrial applications and academic purposes (teaching and research). Hence, in each iteration, some industrial, real-life, and large discrete systems are modelled, and the experiences received from these projects are also incorporated into the tool development. This paper follows the development of GPenSIM through three major iterations and explains the importance and lessons learned during these iterations. [ABSTRACT FROM AUTHOR]
