定义了二元联系数的加性运算法则,给出了几种新的算术集结算子,即二元联系数加权算术平均(BCNWAA)算子、二元联系数有序加权平均(BCNOWA)算子和二元联系数混合集结(BCNHA)算子,提出了一种基于二元联系数的准则权重信息不完全确定的群决策方法.该方法利用BCNWAA算子和BCNHA算子对二元联系数准则值进行集结;利用二元联系数准则值的方差和准则权重的随机性,通过构建优化模型确定最优准则权重.最后,通过实例分析表明了该方法的可行性和有效性. This paper defines the additive algorithm of binary conjunctions, and presents several new arithmetic operators, namely, BCNWAA operator, BCNOWA operator This paper proposes a group decision method based on BCNHA operator and BCNHA operator, which is based on BCNHA operator and BCNHA operator, The criterion value is set up and the optimal criterion weight is determined through the variance of criterion value and the randomness of guideline weight.Finally, the feasibility and effectiveness of the method are illustrated by the example analysis.
