 ABSTRACT

This paper describes the design of a coloured petri net (CPN) model that formalizes the concurrent access to shared resources in a train railroad system. A generic methodology is presented to develop simulation models of asynchronous and non-deterministic railroad operations described in the CPN formalism. Models generated by means of the proposed methodology can be used for strategic decision making to improve operational decisions.
