| 摘 要： | 提出一种使用遗传算法和模糊逻辑相结合进行系统可靠性优化分配的新方法。该方法使用模糊逻辑对系统研制初期可靠性设计中所存在的不精确限制条件和设计目标进行数学建模 ,然后利用遗传算法对数学模型进行求解。该方法充分利用了模糊逻辑的建模效率和遗传算法的搜索效率 ,大大提高了系统可靠性分配的效率和精度。本文首先以两单元串联系统的可靠度优化为例进行说明 ,然后将算法扩展至多单元系统的可靠度及冗余度优化问题的求解。数值仿真实例显示了算法的性能和可行性。

| Abstract: | A new method to perform the apportionment of system reliability with Genetic Algorithm(GA) and Fuzzy Logic(FL) is presented. We employed FL to model the uncertainty within the limits and designing aims during the initial stages of the conceptual design of engineering system, and use GA to find the solution for it. This method boosts the efficiency and precision of system reliability apportionment through exerting the ability of GA&FL. The simulation result shows the performance and feasibility of the new method. |
