Abstract�� The purpose was to present a qualitative and quantitative integrated approach to assess technical risk in aircraft type development project, with multiple attribute decision making methods introduced into it. A fuzzy syntheses evaluating system based on the generally induced ordered weighted averaging (GIOWA) operator was adopted to aggregate the fuzzy linguistic evaluating information used in risk assessment. By quantifying the possibility and consequence respectively, as well as employing risk matrix, the rank of each technical risk scenario was determined, and the whole project-s risk status was evaluated. Finally, a technical risk assessment example for aircraft development project was analyzed to illustrate detailed steps and feasibility of the method given above. It can provide an approach for technical risk assessment in the process of aircraft type development.
Keywords�� risk assessment   technical risk   generally induced ordered weighted averaging (GIOWA) operator   fuzzy evaluation
