Bi-criteria Optimization in Integrated Layout Designof Cellular Manufacturing SystemsUsing a Genetic Algorithm

摘要

Traditionally the design of the physical layout of the manufacturing system and that of the material flow path and material handling system are car-ried out in isolation. In this work, an attempt was made on the integrated layout design, that is, to concurrently design the physical layout and the material han-dling system using a Genetic Algorithm-based methodology. The proposed al-gorithm was employed to simultaneously optimize two contradicting objectives viz., 1. Total material handling cost 2. Distance-weighted cost of closeness rat-ing score. The algorithm was tested on four different benchmark layouts and with different initial problem data sets. It was found that the proposed algo-rithm is able to produce satisfactory solutions consistently within a reasonable computational limit.
