Fuzzy multiple objective optimal system design by hybrid genetic algorithm
In this paper, we propose a method for solving fuzzy multiple objective optimal system design problems with GUB structure by hybridized genetic algorithms (HGA). This approach enables the flexible optimal system design by applying fuzzy goals and fuzzy constraints. In this genetic algorithm (GA), we propose the new chromosomes representation that represents the GUB structure simply and effectively at the same time. Also, by introducing the HGA that combine the proposed heuristic algorithm that makes use of the peculiarity of GUB structure to GA, the proposed approach is efficient than the previous method in finding solution.
