Minimizing Surplus Parts in Selective Assembly Using GA

Selective assembly is a method of obtaining high-precision assemblies from relatively low-precision components. In selective assembly, the mating parts are manufactured with wide tolerances. It is impossible that the number of components in the selective group will be the same, and a large number of surplus parts exist according to the difference in the standard deviations of the mating parts. A method with new grouping method and chromosome structure is proposed to minimize surplus parts by using genetic algorithm.
