摘要
将粒子群算法和局部搜索算法相结合,用于解决串并联系统的冗余分配问题。介绍串并联系统结构,确定该冗余分配问题以系统最小费用为优化目标,以系统可用度不能低于某一确定值为约束条件。应用概率生成函数(UGF)方法计算系统可用度,将粒子群算法和局部搜索算法相结合进行优化求解,并给出迭代过程。通过实例对优化迭代过程进行具体说明。
In this paper, a new algorithm of par- ticle swarm optimization and local search is pro- posed to solve the redundancy allocation problem for series - parallel system. The structure of series -parallel system is introduced in the paper. The new algorithm is used to design the system struc- ture with a minimum cost to provide a desired level of availability. The availability of the system is abtained through the universal generating function （UGF） method. Then the new algorithm is applied to get the optimal solution. The proposed algo- rithm are demonstrated via an illustrative case.
