Based on grey language multi-attribute group decision making, a kernel and grey scale scoring function is put forward according to the definition of grey language and the meaning of the kernel and grey scale. The function introduces grey scale into the decision-making method to avoid information distortion. This method is applied to the grey language hesitant fuzzy group decision making, and the grey correlation degree is used to sort the schemes. The effectiveness and practicability of the decision-making method are further verified by the industry chain sustainable development ability evaluation example of a circular economy. Moreover, its simplicity and feasibility are verified by comparing it with the traditional grey language decision-making method and the grey language hesitant fuzzy weighted arithmetic averaging (GLHWAA) operator integration method after determining the index weight based on the grey correlation.
基于灰色语言多属性群决策，根据灰色语言的定义和核与灰度的含义，提出了核与灰度评分函数。该函数将灰度引入决策方法中，以避免信息失真。该方法应用于灰色语言犹豫模糊群决策中，使用灰色关联度对方案进行排序。通过循环经济产业链可持续发展能力评价实例进一步验证了决策方法的有效性和实用性。而且，通过在基于灰色关联确定指标权重后与传统灰色语言决策方法和灰色语言犹豫模糊加权算术平均（GLHWAA）算子集成方法进行比较，验证了该方法的简单性和可行性。
