考慮愿景的動態(tài)多屬性群決策共識模型

摘要： 現(xiàn)實(shí)中很多的多屬性群決策(MAGDM)問題常常具有以下特征:(1)決策者使用個(gè)人屬性集和愿景集來評估各自的備選方案集,并且個(gè)人屬性集和愿景集可以異構(gòu)。(2)決策者不必就屬性集和愿景集達(dá)成共識。(3)個(gè)人屬性集、方案集和愿景集可以動態(tài)變化。通過將上述實(shí)際情況的特征納入MAGDM,提出一種考慮愿景的動態(tài)多屬性群決策共識模型及其解決框架,設(shè)計(jì)集體解決方案的選擇過程和共識達(dá)成過程的算法,給出為達(dá)成共識對個(gè)人屬性集、個(gè)人方案集、個(gè)人偏好和個(gè)人愿景集的調(diào)整建議,并結(jié)合實(shí)例加以說明。
Many real-world multiple attribute group decision making problems(MAGDM) have the following characteristics:(1) Decision makers use individual attribute sets and aspiration sets to evaluate their alternative sets, in addition, the individual attribute sets and aspiration sets can be heterogeneous.(2) Decision makers don't have to reach a consensus over attribute sets and aspiration sets.(3) Individual attribute sets, alternative sets and aspiration sets can be dynamically changed. With these characteristics of the actual situation included in MAGDM, this paper proposes a consensus model for dynamic multiple attribute group decision making considering aspiration-levels, and proposes its resolution framework. We have designed a selection process of the collective solution and the algorithm of consensus reaching process, and proposed adjustments to individual attribute sets, alternative sets, preferences and aspiration sets to achieve consensus.
