基于區(qū)間粗糙算子的粗糙隨機多準則決策方法
摘要:定義了區(qū)間粗糙隨機變量、區(qū)間粗糙數(shù)的運算法則以及期望值和區(qū)間粗糙集結算子(WIRDAA).針對準則權重信息不完全,準則值為區(qū)間粗糙隨機變量的粗糙隨機多準則決策問題,提出一種基于WIRDAA算子的決策方法.該方法首先計算出變量的期望值矩陣,利用距離最小化建立模型求解出準則權重;然后利用WIRDAA算子求出各方案的綜合評價值,通過比較得到方案集的排序;最后通過實例表明了所提出方法的有效性和可行性.Abstract:The definition of interval rough stochastic variables and the arithmetic operations as well as the expected value of interval rough stochastic numbers are given.And an interval rough operator called interval rough distance weighted arithmetic averaging(WIRDAA)is introduced.For the problem with information of criterion weights incomplete and the evaluation under each criterion represented as interval rough stochastic variables,a method based on WIRDAA operator is proposed.The method calculates the expected value of variables to obtain the expected value matrix.Then a programming model is built to get the criterion weights with the objective function of minimizing the distance.By WIRDAA operator,the overall evaluation of each alternate is obtained,and the resulted ordering of alternates is obtained according to their overall evaluations.Finally,an example shows the feasibility and validity of the proposed approach. 作者: 王堅強唐平 Author: 作者單位: 中南大學商學院,長沙,410083 期 刊: 控制與決策 ISTICEIPKU Journal: Control and Decision 年,卷(期): 2011, 26(7) 分類號: C934 關鍵詞: 多準則決策 區(qū)間粗糙隨機變量 集結算子 Keywords: multi-criteria decision-making interval rough stochastic variables aggregation operators 機標分類號: TP3 N94 機標關鍵詞: 區(qū)間 集結算子 隨機變量的 多準則決策方法 based expected value arithmetic operations evaluation objective function programming model 權重信息不完全 期望值矩陣 information 運算法則 模型求解 決策問題 方案集 最小化 有效性 評價值 基金項目: 國家自然科學基金,國家自然科學基金重點項目,國家創(chuàng)新研究群體科研基金【基于區(qū)間粗糙算子的粗糙隨機多準則決策方法】相關文章:
