基于區(qū)間粗糙算子的粗糙隨機(jī)多準(zhǔn)則決策方法
摘要:定義了區(qū)間粗糙隨機(jī)變量、區(qū)間粗糙數(shù)的運(yùn)算法則以及期望值和區(qū)間粗糙集結(jié)算子(WIRDAA).針對(duì)準(zhǔn)則權(quán)重信息不完全,準(zhǔn)則值為區(qū)間粗糙隨機(jī)變量的粗糙隨機(jī)多準(zhǔn)則決策問(wèn)題,提出一種基于WIRDAA算子的決策方法.該方法首先計(jì)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(zhǔn)則權(quán)重;然后利用WIRDAA算子求出各方案的綜合評(píng)價(jià)值,通過(guò)比較得到方案集的排序;最后通過(guò)實(shí)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(jiān)強(qiáng)唐平 Author: 作者單位: 中南大學(xué)商學(xué)院,長(zhǎng)沙,410083 期 刊: 控制與決策 ISTICEIPKU Journal: Control and Decision 年,卷(期): 2011, 26(7) 分類號(hào): C934 關(guān)鍵詞: 多準(zhǔn)則決策 區(qū)間粗糙隨機(jī)變量 集結(jié)算子 Keywords: multi-criteria decision-making interval rough stochastic variables aggregation operators 機(jī)標(biāo)分類號(hào): TP3 N94 機(jī)標(biāo)關(guān)鍵詞: 區(qū)間 集結(jié)算子 隨機(jī)變量的 多準(zhǔn)則決策方法 based expected value arithmetic operations evaluation objective function programming model 權(quán)重信息不完全 期望值矩陣 information 運(yùn)算法則 模型求解 決策問(wèn)題 方案集 最小化 有效性 評(píng)價(jià)值 基金項(xiàng)目: 國(guó)家自然科學(xué)基金,國(guó)家自然科學(xué)基金重點(diǎn)項(xiàng)目,國(guó)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(jī)多準(zhǔn)則決策方法】相關(guān)文章:
