摘要
本系统是示范工程FCSCIMS(飞行控制系统计算机集成制造系统)技术可行性论证系统的一个子系统,它是基于数据库,辅助决策者针对数字式飞行控制系统硬件相似余度方案设计的决策支持系统.它建立了以分层型结构为基础的决策支持系统的总体框架;应用余度技术领域专家的知识,建立了余度模型库;系统考虑了可维修性指标与可用度指标;提出了以综合考虑系统重量、体积、成本与技术风险度等指标的多目标专家评估法为基础的决策模型.仿真结果表明,余度方案论证的流程和决策方法是可行的.
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.
