Abstract

Fluid(or Hybrid) Petri Nets are Petri net based models with two classesof places: discrete places that carry a natural number of distinctobjects (tokens), and fluid places that hold a positive amountof fluid, represented by a real number. With respect to previousformulations, the FSPN model presented in this paper, is augmentedwith a new primitive, called flush-out arc. A flush-out arc connectsa fluid place to a timed transition, and has the effect of instantaneouslyemptying the fluid place when the transition fires. The paperdiscusses the modeling power of the augmented formalism, andshows how the dynamics of the underlying stochastic process canbe analytically described by a set of integro-differential equations.A procedure is presented to automatically derive the solutionequations from the model specifications. The whole methodologyis illustrated by means of various examples.
