| 摘 要： | 提出一种改进的模糊优选多目标优化遗传算法.算法采用个体在总群体中的相对优属度作为适应度值,将总群体中的全部个体按子目标函数的数量平均划分为子群体,对每个子群体分配1个子目标函数,以子目标函数值计算子群体中个体的适应度值.2次选择后满足了整体最优的要求,又尽可能地逼近各子目标最优值.经实例计算,效果显著.

| Abstract: | An improved genetic algorithm based on fuzzy evaluation for muhiobjective optimization was proposed. The traditional fitness function has been replaced by fuzzy evaluation function, and the population was subdivided averagely according to the number of sub-object functions, then traditional selection operation was done in subdivision population. After two time selection, the algorithm could obtain optimal multiobject value and sub-object value. Some evaluative examples showed that the results were better. |
