Abstract
In this paper, a new layout expression based on the location matrix and some heuristics are proposed for the determination of aisle structure and I/O locations of each department in a facility layout problem. The proposed genetic algorithm-based algorithm finds multiple solutions along the Pareto optimal frontier. The objective here is to minimize (1) material handling cost and (2) building area. The material movements assume that they are transferred along the shortest distance aisle between the I/O locations of those departments. The results of computational experiments show the effectiveness of the proposed algorithm.
