A Method for Engineering Design Selection of Complex Systems Based On System Engineering

The modern complicated large engineering is significant to the nation and society. The initial conceptual design selection could decide most of the whole engineering project. It's a multi-objective, multi-criteria, multi-field process. Basing experts' experience, the traditional plan selection depends largely on qualitative information and is subject to subjective factors. The modern decision making methods can help the process more quantitative and objective. Using System Engineering (SE) methodology combined qualitative and quantitative information, this paper discusses a comprehensive and concise method about the complex system design selection and decision making. The weight and metrics are discussed as the important impact during objective break-down, quantitative modeling and accessing. expert knowledge of complicated engineering project is conducted, in order to support a more objective, science-based decision making during conceptual design phase of large engineering system design.
