THE PERFORMANCE BASED SELECTION SYSTEM OF EXTERIOR WALL MATERIALS

The purpose of this research is to develop the design support system that can select the material composes the exterior wall of the building optimally based on the demand performance. Various performances like safety, durability, and livability, etc. are demanded from architects, builders and users for the exterior wall. The trade-off relation such as a superior one in a certain evaluation index is judged inferior in another index occur under multiple evaluation indices. In this research, the exterior wall of the building is described as a planar stratified that is composed of combination of board materials. As a result, the material selection system applied Genetic Algorithm (GA) can derive the appropriate solution with plural performance criteria.
