Abstract: Petri nets are powerful techniques for modelling and studying discrete event systems. They are extensively used in both specification and quantitative analysis of such kind of systems. We introduce a layered modelling approach refers to here as MORaD-net. It is based on Coloured Petri Nets (CPNs). An integration of top-down and bottom-up approaches is applied to increase the usability of MORaD-net and to elucidate the relations between different objects in business processes. MORaD-net comprises three layers: the system layer, the process layer, and the resource layer. It is a ready-to-simulate modelling technique. MORaD-net is able to trace the behaviour of each instance of a process and to report the performance of the system resources. To testify the effectiveness of MORaD-net, experiments have been run which prove that MORaD-net is a reliable visual modelling technique of processes in both design and execution phases. It allows the analysis of the process based on different scenarios.
