Decision Based Modeling of a Flexible Manufacturing Cell based on Hierarchical Timed Colored Petri Nets

The design techniques of flexible manufacturing systems deal, among other methods, with the application of high level Petri Nets. The modeling and simulation of a flexible manufacturing cell (FMC) can be done by implementing hierarchical techniques based on Colored Timed Petri Nets. This paper is focused on implementing decisions and strategies in a flexible manufacturing cell with colored and hierarchical techniques. In this context we discuss the decision making for machine, parts and allocated tools in transitions. The FMC model is designed based on the cell operating at the laboratory of the Faculty of Managerial and Technological Engineering, University of Oradea. In this article, we explain the design techniques using color and hierarchy to evaluate the overall performance of the cell based on part arrival decisions and part processing decisions in transitions of each sub-model of the cell.
