Timed hybrid Petri Nets visual simulation in VPNP

Abstract

This paper presents a visual simulation of timed hybrid Petri nets (HPN) a class of Petri nets in which some places may hold fluid rather than discrete tokens. The simulation software has been developed and implemented in Visual Petri Nets + tool (VPNP) and offers a graphical user interface. The continuous transitions of the net are fired with speeds that are piecewise constants or variable.
