This research is devoted to the development of a multiobjective facility layout creation methodology. This methodology seeks to extend the scope of existing computerized and manual layout creation methods by capturing a greater level of both intuitive and quantitative inputs in a method applicable for moderate to large-scale problems. To do this, an extended theoretical basis for decision theoretic models applicable to layout design is described. Using these models as an evaluation basis, a new optimizing layout creation strategy is developed and a decision support system for its implementation is presented. The new layout creation method is computationally attractive, and based on extensive computational experience, is found to give better solutions than those generated by CORELAP. / Ph.
