摘要
以一种综合模糊数学与灰色理论的方法评价多类别复杂系统中的对象 .先根据专家对各对象关于各指标的打分 ,求出各类别的隶属度矩阵 ,然后基于灰色理论的差异信息原理 ,提出一个灰色隶属度算子来强化差异信息、弱化相似信息 ,求得各类别新的隶属度矩阵并依据它们的信息来确定类别权系数 ,进而求得最终的隶属度矩阵 ,最后通过计算平均隶属度来评价对象 .应用这种方法 ,对江西铜业公司尾矿库管理标准化评比资料进行了分析 ,所得结果符合实际 .图 1,表 1,参 10 .
A new method synthesized fuzzy mathematics and Grey theory is presented to evaluate the objects of multi-sort complicate system. At first, using this method, the matrix of membership degree of each sort is gotten according to the marks, which are each object about each index ,made by experts. And then based on the discrepancy information principle of Grey theory, an arithmetic operator of Grey membership degree is put forward to aggrandize discrepancy information as well as to infirm similar information. By this means, the new matrix of membership degree of each sort is obtained and its information is used for determining the coefficient furthermore the last matrix of membership degree of each sort can be worked out. Finally, the objects are evaluated by their average membership degree. As an application, the paper analyzes the data of the management standardization of the tailing reservoir in Jiangxi Copper Corporation. The result is close to the practice.1fig.,1tab.,10refs.
