ABSTRACT
Linear mathematical relations have been developed from the results of the Taguchi design of experiments and the analysis of variance between the input parameters, namely, blank-holder force, friction coefficient, die profile radius, and punch nose radius. The performance characteristics applied for the connector is wrinkling factor. The least square method is employed for measuring the distance of the wrinkling points. This chapter talks about numerical simulation which was conducted with the optimum parameters achieved after optimization with the firefly algorithm (FA). The FA is one of the evolutionary optimization algorithms, and is encouraged by fireflies' behavior in Mother Nature. In a certain sense, there is some conceptual similarity between the FA and the bacterial foraging algorithm (BFA). In BFA, the attraction among bacteria is based partly on their fitness and partly on their distance, while in FA, the attractiveness is linked to their objective function and monotonic decay of the attractiveness with distance.
