Application of Fuzzy C-Means Clustering and Genetic Algorithm in the Fabrication of Circuit Board

摘要

Real world problems are full of uncertainty. Probability theory can deal with uncertainty up to a certain limit. After Newtonian mechanics, physicists along with mathematicians were trying to formulate a wide variety of theories of probability. Today also there exist relative frequency theory and the personalistic or subjectivist theory which are among the most popular ones but probability theory demands equally likely and mutually exclusive outcomes as well. Actual real world problems like optimization of laser drilling time of circuit boards, cannot be solved by the theories of probability though having uncertainty. Uncertainty is in another way just the inverse of information we have about any system. The more complex a system becomes, the less certain we can be in proper analysis of that system, its formulation and solution. Imprecise human reasoning forms the basis of our initial understanding of most physical processes but computers should be provided with precise and quantified quantities of information. The efficacy of fuzzy logic can be judged in this criterion. This context is for analyzing and ascertaining the optimality of using fuzzy logic along with genetic algorithm, while minimizing the laser drilling time of circuit boards.
