| 摘 要： | 为了在可靠性指标分配时能充分利用相似旧机型已有的可靠性信息,提出在航空发动机初期设计的可靠性分配阶段采用模糊相似比例与模糊综合评判相结合的可靠性指标分配方法.该方法既能充分利用相似旧机型的可靠性数据,同时又能通过模糊综合评判,对基于相似旧机型的可靠性比例分配结果进行修正,实现了在可靠性分配阶段确定性信息和不确定信息的互补,进一步优化了可靠性分配结果.

| Abstract: | In this paper,an approach based on fuzzy prorating method and fuzzy synthetic assessment was proposed to allocate the reliability indices,by utilizing the existing reliability information from the similar version of aeroengine in the early design phase.The proposed approach not only considers the reliability information and data from the old version products,but also combines the information from fuzzy synthetic assessment as a complement.This method efficiently utilizes the certain and uncertain informatio... |
