基于ELECTRE方法的模糊多属性决策

针对传统ELECTRE法的弱点,将ELECTRE法拓展到了模糊环境下,得到一种解决模糊多属性决策问题的新方法,决策评估中涉及到的属性值与属性权重值等模糊信息以三角模糊数形式给出。首先集结决策者对各方案属性的评价,确定出模糊决策矩阵;其次根据信息熵原理,求解出三角模糊数型的属性权重向量;最后给出新的模糊ELECTRE方法的决策步骤。新方法既具有统一的表达形式,又克服了传统方法中和谐性与不和谐性之间具有一定相关性的缺陷。新方法计算简单,给出的实例验证了此方法的可行性和有效性。

Fuzzy Multiple Attribute Decision Based on ELECTRE Method

For the weakness of traditional ELECTRE method, the ELECTRE method is expanded to a fuzzy environment, and a new method of solving the problem of fuzzy multiple attribute decision is gained. Some fuzzy information such as attribute value and attribute weights value which are related to decision evaluation are displayed in the form of triangular fuzzy number. First of all, the evaluation of every solution properties from decision maker is aggregated to determinate the fuzzy solution matrice; secondly, accord...
