Extending a Petri Net Simulator as a real-time control simulator

Discrete event dynamic systems (DEDS) are prevalent in many areas of engineering, like manufacturing, maintenance, distributed computing, etc. Activities or discrete events in DEDS are generally large in numbers, highly parallel, distributed, and highly intertwined. Modeling DEDS systems are further complicated by the fact that the decisions to be made from the model may incorporate inference engines that uses advanced statistical analysis on massive data and may also include fuzzy decisions. This paper talks about development of a new tool for modeling and simulation of DEDS that can satisfy the characteristics mentioned above; the new tool is called General purpose Petri net Simulator (GPenSIM). This paper further presents a recent extension to the new tool, which is the real-time simulation capability.
