Abstract: This paper introduces a new approach for the verification of behaviour properties in hybrid systems. By using Petri nets and object oriented concepts ...
regulations include temporal aspects: for example the maximum delay for a property transaction or a trial setting down. The major part of legal rules comprise ...
These points underline a need for a repository to manage models using different for- malisms, and centered on different types of semantics. Also, models should ...

In this article we report the results of the survey and we outline perspectives for ... For example, using a low-level modeling formalism with ad-hoc optimizations.
We underline here the fact that if the Petri net repre- sents the resource allocation policies of a shop, any short term scheduling issue can be expressed under.
