Decision Support System (DSS) of the Digital Flight Control System's (DFCS's) redundant scheme design belongs to the technical feasibility system on FCS CIMS. It is mainly for the design of similar redundancy in hardware of the DFCS. A sandwich DSS framework is built according to the DSS structure and function. A redundancy model library is established to make use of the experts' knowledge on redundancy technology. Maintainability and availability indices are considered during the design stage. A decision model based on expert evaluation method with multi object is built which considered the system weight, volume, cost and technical risk. The simulation proves that the demonstration process and the decision making method is feasible.
