This paper presents a formalism called Time Interval Petri Nets (TIPNs), which are designed to support a qualitative simulation of temporal concurrent processes. One of the key features of TIPNs is a uniform use of time intervals throughout the model. This enables a natural and efficient representat

✦ Synopsis
Processes of timed Petri nets are represented by labelled partial orders with some extra features. These features re ect the execution times of processes and allow to combine processes sequentially and in parallel, which leads to some algebras. The processes can be represented either without specifying when particular situations appear (free processes), or together with the respective appearance times (timed processes). The processes of the latter type determine the possible ÿring sequences of the respective nets.

## TIMED PETRI NETS Petri nets were developed as an operational formalism for specifying untimed concurrent systems. They can show concurrent activities by depicting control and data flows in different parts of the modeled system. As an operational formalism, a Petri net gives a dynamic representa
The first goal of this work is to extend a model of Timed Safe Petri Nets to allow the treatment of preference between transitions. In the proposed Possibilistic Timed Safe Petri Net, we attach a duration to each transition, which can be precise, imprecise, or fuzzy, accounting for the maximal amoun
