摘要
在V ague集理论的表决模型中引入了倾向性因子,并据此提出了一种可靠性影响因素赋权的方法。将此方法与模糊综合评判理论结合,建立了综合评判系统各单元之间相对失效系数的模型。然后借助该模型及MATLAB软件,提出了一种具有冷贮备单元的航空发动机数控系统可靠度的模糊分配方法。该方法适用于缺乏可靠性数据的方案论证及初步设计阶段。
The tendency factor was introduced into the voting model in Vague sets, and the weighting method for the influential factors of reliability was proposed. Combined with the fuzzy decision-making theory, the model synthetically assessing the relative failure coefficients between the units of a system was developed. The approach to fuzzy reliability allocation for an aeroengine digital control system with cold standby units was presented with the aid of the model and MATLAB. This approach is suitable for conceptual and preliminary design where there is lack of system reliability data.
