结合投资决策的特点给出了一种模糊多属性决策方法，其中属性偏好信息以若干个互补判断矩阵形式给出，属性值为梯形模糊数。该方法能充分挖掘判断矩阵的特征信息，给出了互补判断矩阵相似度和属性优势度的定义，从而确定专家权重和属性权重。基于梯形模糊数外接圆的圆心与原点之间所形成的矩形面积来对模糊数排序的方法对方案进行排序和择优。通过对服务行业的项目评估问题说明该方法是求解模糊多属性决策问题的一种有效的工具，并且操作简便、易于在计算机上实现。
結閤投資決策的特點給齣瞭一種模糊多屬性決策方法，其中屬性偏好信息以若榦箇互補判斷矩陣形式給齣，屬性值為梯形模糊數。該方法能充分挖掘判斷矩陣的特徵信息，給齣瞭互補判斷矩陣相似度和屬性優勢度的定義，從而確定專傢權重和屬性權重。基于梯形模糊數外接圓的圓心與原點之間所形成的矩形麵積來對模糊數排序的方法對方案進行排序和擇優。通過對服務行業的項目評估問題說明該方法是求解模糊多屬性決策問題的一種有效的工具，併且操作簡便、易于在計算機上實現。

In this paper, a method for fuzzy multi?attribute decision?making problem considering the characteristics of investment decisions is investigated. The preference information about attribute weights given by the decision makers is in the form of complementary judgment matrixes and the attribute value in the decision matrix is trape?zoidal fuzzy number. The attribute weight and expert vectors are received by exploring the feather information of judgment matrixes given by experts about attribute. A new method for ranking alternatives by using ranking trape?zoidal fuzzy number based on the area between circumcenter of centroids of a fuzzy number and origin is proposed. Finally, a project evaluation problem for services showed that the proposed method is an effective tool to solve the fuzzy multi?attribute decision?making problems,featuring by simple operations and easy implementation on a com?puter.
