针对语言环境不确定的多准则群决策问题，提出了一种两阶段（共识过程和选择过程）的求解方法。由于实现普遍共识是一个理想的目标，在群体决策，所提出的方法首先开发了一个共识达成过程，以达到一个令人满意的共识。基于不确定语言变量的偏序关系，定义了方案在给定准则下的优势指数和方案的总体优势指数。然后描述了一个基于优势指标的最佳方案选择过程。鉴于决策者的愿望，一个共识的解决方案，以前的共识模型和选择过程的基础上，提出了一个共同的框架。最后，通过一个实际应用实例验证了该方法的有效性.
A two-stage (a consensus process and a selection process) approach is proposed to solve multi-criteria group decision making problems under an uncertain linguistic environment. Since achieving general consensus is a desirable goal in group decision making, the proposed method first develops a consensus reaching process in order to reach a satisfactory consensus. Based on the partial order of uncertain linguistic variables, the superiority index of one alternative over another for a given criterion and the overall superiority index of one alternative are defined. Then a procedure based on the superiority indices is described to select the best alternative(s). Given the decision makers’ desire for a consensus solution, a common framework based on the previous consensus model and the selection process is presented. Finally, a practical application is demonstrated to show the effectiveness of the proposed method.
