Two New Approaches to Multiobjective Optimisation Using Genetic Algorithms

In this paper, two new multiobjective optimization techniques based on the genetic algorithm (GA) are introduced. These methods are based in the concept of min-max optimum, and can produce the Pareto set and the best trade-off among the objectives. The results produced by these approaches are compared to those produced with mathematical programming techniques and other GA-based approaches using a multiobjective optimization tool called MOSES. This tool, developed by the author, is a convenient testbed for analyzing the performance of new and existing multicriteria optimization techniques, and it is an effective engineering design tool.
