Evaluation of Printed Circuit Board Assembly Manufacturing Systems Using Fuzzy Colored Petri Nets

In this paper, implementation and evaluation of a Printed Circuit Board Assembly (PCBA) manufacturing system model based on papers of Fuzzy Colored Petri Nets (FCPN) modeling tel:hnique was performed. From the Petri nets simulation results, two contributions were claimed: (1) The successful application of our approach to evaluate systems that consist of complicated concurrent processes with embedded data structures and uncertainty reasoning. (2) An approach in automatic determination of the threshold values in the fuzzy production rules using FCPN. The details of the assembling processes and various manufacturing data were gathered from I:omputer manufacturers located in China. Different resources allocation strategies were introduced in the experiments, and simulation results were obtained. The resources included screen printers, different pick and place machines, infrared soldering machines and components insertion robots. All the experiments were b.rilt by using the Petri Net tool DESlGNiCPN [6]. A number of hierarchy pages, color sets, places, arcs and transitions representing the PCPA and fuzzy producticn rules were constructed in the experiments. Simulation runs of the Petri nets model were carried out. The result shows that our approach could be used to guide decision makers in the design and selection of a suitatsle PCBA manufacturing strategy. Future extension of our work is described at the end of this paper.
