Comparison of optimization techniques applied to a flexible manufacturing system

Resumen

In order to solve optimization problems of manufacturing or logistic systems, certain difficulties as the state explosion problem must taken into account. There are several techniques based on simulation of the model and space state exploration, and several techniques of analysis of the system, that aid in the task of finding an optimal behavior, or at least a valid solution. When the model of the system is developed with Petri nets, it is possible to apply some analysis techniques specific of this formalism. This work present a combined use of different analysis and simulation techniques applied to a case study derived from an industrial manufacturing system, in order to obtain a valid solution for the optimization problem. The conclusions obtained from the application of these techniques are presented, compared to the results calculated by means of an evolutionary algorithm.
