摘　　要：利用模糊语言变量和模糊数适于量化模糊信息的特点,从评价集设置、因素权重赋值和单因素评判等方面,对现有的模糊综合评判方法进行改进,然后据此提出了一种设计初期航空发动机可靠性模糊分配的方法,该方法可在可靠性数据缺乏的情况下。By the use of fuzzy linguistic variables and fuzzy numbers, the current fuzzy synthetic assessment methods have been improved in the aspects of comment setting, factor weights and single factor assessment. On this basis, a new approach is presented, which is suited to the reliability fuzzy apportionment in the initial design phase of an aeroengine. With this approach, the results of the aeroengine failure- index apportionment at different confidence levels can be obtained according to the expertise despite the absence of reliability data.
