摘　　要：基于可靠性理论和模糊集合论,提出了一种新的小子样武器系统可靠性分析和评定方法。阐述了将各种模糊可靠性数据转化成梯形模糊数的途径;建立了计算串联系统和并联系统的梯形模糊数算术运算的可靠度计算模型;依据层次分析法和专家调查法给出了武器系统可靠度模糊评定的计算公式。通过两个鱼雷武器系统的应用实例证明了此方法的工程实用性。A new reliability analysis and evaluation method for small sub-sample weapon system based on the reliability theory and fuzzy set theory is proposed. The methods to transform various kinds of fuzzy reliability number into trapezoidal fuzzy number are discussed. The reliability calculated models for the series system and parallel system based on trapezoidal fuzzy number arithmetic operations are established. The reliability fuzzy evaluation formulation for weapon system using the analytic hierarchy process and expert investigation method is given. The engineering practicability of the new method is proven by two examples of torpedo weapon system.
