针对一类属性值、属性权重和决策者权重均为区间灰数的群决策问题,引入群体正靶心、负靶心和群体偏离靶心度的概念,提出了灰色多属性偏离靶心度群决策方法,即群决策的结论应尽量接近所有成员最理想的方案,即越接近群体正靶心而同时又远离群体负靶心的方案,则方案越优.文章分别给出了灰色多属性群决策问题的决策矩阵的构建及规范化,提出了正负群靶心及群靶心距的计算方法;最后,利用群体偏离靶心度的大小对各方案的优劣进行排序,实现多目标群决策.文末通过算例说明了该方法的有效性.
針對一類屬性值、屬性權重和決策者權重均為區間灰數的群決策問題,引入群體正靶心、負靶心和群體偏離靶心度的概唸,提齣瞭灰色多屬性偏離靶心度群決策方法,即群決策的結論應儘量接近所有成員最理想的方案,即越接近群體正靶心而同時又遠離群體負靶心的方案,則方案越優.文章分彆給齣瞭灰色多屬性群決策問題的決策矩陣的構建及規範化,提齣瞭正負群靶心及群靶心距的計算方法;最後,利用群體偏離靶心度的大小對各方案的優劣進行排序,實現多目標群決策.文末通過算例說明瞭該方法的有效性.

The off-target deviation degree method is presented for grey multi-attribute group decision-making problem in which its attribute value, attribute weight and authority weight are interval grey numbers. The concepts of positive group target, negative group target and group off-target deviation degree are respectively proposed. The approach for measuring group off-target deviation degree is given to determine which program is best one from the viewpoint of positive and negative ideal solutions based on TOPSIS. The simulation results show the method is very effective.
