摘要
分布估计算法是一类新的进化算法,它通过统计在当前群体中优选出的个体信息给出下一代个体分布的概率估计,用随机取样的方法生成下一代群体.将分布估计算法应用于备件优化问题,提出了基于分布估计算法的武器装备系统备件优化模型,分析了个体选择比例、精英保留等策略对算法的影响.仿真结果表明了文中所采用的分布估计算法在求解备件优化问题时是可靠有效的.
Estimation of Distribution Algorithms(EDAs) is a new kind of evolution algorithm.In EDAs, through the statistics of the information of selected individuals in current group,the probability of the individual distribution in next generation is given and the next generation of group is formed by random sampling.In this paper,the EDAs is applied to solve the spare parts optimization,and the model of spare parts optimization based on EDAs is given.The influence of several strategies,such as population selection ...
