| 摘 要： | 在考虑成本的基础上,通过建立一种实用的成本-可靠度函数和非线性规划模型,将对组件的可靠性最优分配的问题转化为对非线性规划问题的求解,从而为复杂系统可靠性的最优化问题提出了一种新的方法.对于非线性规划问题,为获得具有实际意义的数值解,提出了一种具有自适应的改进型遗传算法,对非线性规划问题求解,解决了更复杂结构系统可靠性分配的优化问题.

| Abstract: | A new method of distribution and optimization of reliability of complex systems was presented. The problem of distribution and optimization of reliability complex systems which were constructed on component level was reduced to the problem of nonlinear programming by building practical cost-reliability function and nonlinear programming model which considered the effect of cost in the distribution and optimization of reliability. In order to gain feasible numerical solution in the nonlinear programming problem,an improved genetic algorithm which had self-adaptation function was proposed. By using this method,distribution and optimization of reliability of more complex system can be solved effectively and efficiently. |
