This paper presents the results of a research and development study on the Wing Structural Layout Decision Support System (WSLDSS) for fighters. The wing structural layout design is an ill-structured problem that has to consider masses of quantitative and qualitative factors, and cannot be effectively solved only by algorithm-based methods. It is a complex decision making process in which expert experience and knowledge play a most important role. So we introduce decision theory and methods into structural layout design, and consider it from the angle of decision-making rather than only optimization for lightening weight. The scope of this study work, the solving strategy for wing structural layout decision, as well as corresponding technological measures adopted are presented. Integrating the technique of Expert, System and that of Decision Support System, the structure framework of WSLDSS was proposed and the prototype system is being developed.
