【摘要】 针对模糊综合决策中权重的确定,提出了一种新的解决方法——用遗传算法来求解.遗传算法具有全局搜索能力,可以找到一个近似的最优解,在算法中应用了替换操作,以提高种群的多样性,有效地避免早熟现象的发生.此算法克服了其他方法主观性偏强的缺点,实验结果也表明算法是有效的.更多还原

【Abstract】 Weight confirmation is a vital problem in fuzzy comprehensive decision-making.Many valid methods have been put forward,but these methods have a common drawback—subjectivity which may distort the result of estimation.This paper puts forward a new solution—genetic algorithm to the problem,which is of overall ability to find the approximately best result.In the algorithm,the replacement operation is used to avoid prematurity.This algorithm overcomes the drawback of other methods.The results in the experiments show the algorithm is valid.更多还原
