在用模糊数量化模糊信息的基础上,改进了常规的模糊综合评判方法,并用此方法对燃气轮机子系统的可靠度进行模糊预计,得到它们的可靠度置信区间。然后在此基础上,以研制费用作为资源约束,提出一个具有实际工程应用价值的燃气轮机可靠度优化分配模型。 Based on the fuzzy quantification of fuzzy information, the conventional fuzzy comprehensive evaluation method is improved. With this method, the reliability of gas turbine subsystem is estimated by fuzzy method, and their reliability confidence intervals are obtained. Then, on the basis of this, taking the development cost as a resource constraint, this paper proposes a gas turbine reliability optimization distribution model with practical engineering application value.
