摘要
提出了一种新算法用于寻找带冗余串联系统可靠性的最优冗余分配.该算法由2个部分组成,首先应用算术 几何平均值不等式搜寻一个次最优解,以此作为直接法的初始解;然后根据改进的Aggarwal选择准则,启动直接算法以最终确定最优解.与一些优化技术相比,该算法结合了精确法与直接法的优点,求解较精确,效率较高.
A new optimization technique is developed for finding the optimal redundancy allocation of a series system.The algorithm comprises two phases,one of which is designed to search a so-called suboptimal redundancy solution by applying the arithmetic mean-geometric mean inequality and the other is a heuristic procedure based on the Aggarwal et al.'s criterion beginning with the suboptimal solution,finally to determine the optimality.Compared with some existing optimization techniques,the approach proposed in the paper combines the superiority of exact with heuristic,and proves more accurate and efficient.
