Simulation of colored time Petri nets

2013 IEEE International Conference on Information and Automation (ICIA), 2013
This paper presents a simulation algorithm to analyze a type of colored time Petri nets, in which a time interval is associated with each transition. Specifically, we first unfold colored time Petri nets to standard time Petri nets and then develop a simulation algorithm of time Petri nets to realize the simulation of colored time Petri nets.

Passage times in colored stochastic petri nets

Stochastic Models, 1993
Summary: Passage times in colored-stochastic Petri nets correspond to delays in discrete-event stochastic systems. Formal definition of a sequence of passage times in a colored stochastic Petri net is in terms of the underlying general state space Markov chain of the marking process.

Improvements in Unfolding of Colored Petri Nets

2021
Colored Petri nets offer a compact and user friendly representation of the traditional P/T nets and colored nets with finite color ranges can be unfolded into the underlying P/T nets, however, at the expense of an exponential explosion in size. We present two novel techniques based on static analyses in order to reduce the size of unfolded colored nets.

Towards reusable colored Petri nets

Proceedings International Symposium on Software Engineering for Parallel and Distributed Systems, 2002
Reuse has long been recognized as a key technology that can bring about signi cant productivity gains in software development. Code-level reuse is wellunderstood and frequently practiced. However, reuse in software requirements, another phase where much bene t can be expected, remains inadequately addressed.

Colored Petri net control of OR-logic

Proceedings of the IEEE Internatinal Symposium on Intelligent Control, 2003
Usually, the maximally permissive control of Petri nets with an OR-logic constraint is difficult to implement. In this paper, OR-logic is easily enforced using a colored Petri net. A colored Petri net place, named colored monitor place, is designed to monitor the states of constraints.

Conflict sets in colored Petri nets

Proceedings of 5th International Workshop on Petri Nets and Performance Models, 2002
Generalized stochastic Petri nets provide the modeller with immediate transitions, but a model will be correct only if the modeller can specify how to solve the firing conflicts between these transitions. This task is usually cumbersome and may be impossible for large nets.
