Timed Coloured Petri Nets for Modelling and Managing Processes and Projects

The proposed article describes a new approach for project/process modelling based on Timed Coloured Petri Nets (TCPNs), to simplify the resource allocation in a resource-constrained problem. In particular, its utilisation provides a robust formalism to represent and analyse parallel systems. The TCPNs utilisation allows analysing interdependencies, criticality, substitution, conflicting resource priorities and variations in the availability of resources. This paper proposes a new model and highlights the usefulness of the model for real-time activity scheduling in a resource-constrained project environment. A case study for an industrial project is described to provide a systematic analysis of the proposed tool.
