针对评价信息、属性权重均为不同粒度语言短语的多属性群决策问题，提出一种基于主客观权重集成及扩展多准则协调优化解（VIKOR）的多属性群决策方法。由基本语言评价集实现对多粒度语言评价矩阵的一致化，基于同一粒度的语言决策矩阵计算群体对属性的评价偏差，基于群体评价意见的一致性原则得到属性客观权重，通过二元语义加权算术平均（T-WAA）算子得到属性主观权重，从而集成主、客观权重求得属性综合权重。集结转化后的单个评价矩阵得到群体评价矩阵及其导出矩阵，由扩展VIKOR方法，根据群效用值、个体遗憾值及综合评价值分别对方案进行排序，获得折衷方案。算例分析表明该方法的有效性与可行性。
針對評價信息、屬性權重均為不同粒度語言短語的多屬性群決策問題，提齣一種基于主客觀權重集成及擴展多準則協調優化解（VIKOR）的多屬性群決策方法。由基本語言評價集實現對多粒度語言評價矩陣的一緻化，基于同一粒度的語言決策矩陣計算群體對屬性的評價偏差，基于群體評價意見的一緻性原則得到屬性客觀權重，通過二元語義加權算術平均（T-WAA）算子得到屬性主觀權重，從而集成主、客觀權重求得屬性綜閤權重。集結轉化後的單箇評價矩陣得到群體評價矩陣及其導齣矩陣，由擴展VIKOR方法，根據群效用值、箇體遺憾值及綜閤評價值分彆對方案進行排序，穫得摺衷方案。算例分析錶明該方法的有效性與可行性。

To deal with multi-attribute group decision making problems with multi-granularity linguistic phrases of attri-bute values and attribute weights, a method based on subjective-objective attribute weights integrated and extended Vlsekriterijumska Optimizacija I Kompromisno Resenje(VIKOR)is proposed. The multi-granularity evaluation matrices are unified into the same granularity by the basic linguistic term set, The group evaluate deviations to every attributes are calculated according to the translated linguistic decision matrixes, then the objective weights are obtained by the consisten-cy principle of group evaluation opinions, subjective weights of every attributes are calculated by using the Two-tuple Weighted Averaging(T-WAA)operator, thus, subjective weights and objective weights of attributes are concentrated into comprehensive weights. Evaluation matrixes given by all decision makers are aggregated into group evaluation matrix and its export matrix. Based on extended VIKOR method, the compromise rank result of alternatives is obtained from the group utility values, individual regret values and comprehensive evaluation values. An illustrative example analysis shows the effectiveness and feasibility of this method.
