摘要
为确保直升机在投入生产之前对其性能状态有全局性和整体性评价,根据直升机供电系统的研制特点,建立了设计阶段的供电系统评估指标体系,对该体系的递阶层次结构进行了分析及论述。结合现今系统评估的研究现状以及指标系统的特征,采用模糊综合评估方法对系统进行性能综合评估,着重对模糊评估模型的建立进行了详细分析,运用层次分析法确定各影响因素指标权重,尤其是针对不同专家确定的模糊判断矩阵运用最小二乘法得出更为客观科学的权重分配。利用此方法对某型直升机供电系统的综合性能进行了评估,评估结果表明了此模型的有效性和准确性。
In order to ensure the helicopter for the performance status with overall and holistic evaluation before production,based on the characteristics of the helicopter power supply system,we established the evaluation index system of the power system in design phase,and the pass class hierarchy of that system are analyzed and discussed.Combined with current research situation of the assessment system and the characteristics of the index system,we use the fuzzy comprehensive evaluation method for system property to comprehensively evaluate,especially the establishment of fuzzy assessment model are analyzed in detail.Using analytic hierarchy process（AHP）to determine the index weight of each affecting factor,particularly for the fuzzy judgment matrix determined by different experts we use the least square method（LSM）for more objective and scientific weight distribution.With this method to evaluate the comprehensive property of a certain type of helicopter power supply system,the evaluation result reflects the validity and accuracy of this model.（School of Automatic Science and Electrical Engineering, Beihang University, Beijing 100191, China）
