In a world where the linear economy has already proven its limits. Sustainable development through circular economy becomes a necessity more than a choice. To verify the adequacy between a sustainable development objective and the related management of operations, a variety of performance indicators exist in the literature and an overall is required to ease comparisons. Here we use an extended fuzzy weighted product to avoid overvaluation of an indicator over the others. To handle qualitative aspects, fuzzy logic is used to shorten the gap between humans’ perception and machine language. These qualitative features require various evaluators to reduce bias. Thus, a coherence measure is adapted. KeywordsCircular economy (CE), Multi-criteria decision making (MCDM), Fuzzy consensus, Fuzzy weighted product.

衡量循环经济效率的模糊乘性绩效指标

在线性经济已经证明其极限的世界中。通过循环经济实现可持续发展已成为不可替代的选择。为了验证可持续发展目标和相关的运营管理之间的充分性，文献中存在各种绩效指标，并且需要一个总体指标来简化比较。在这里，我们使用扩展的模糊加权乘积来避免指标相对于其他指标的高估。为了处理定性方面的问题，模糊逻辑用于缩短人类感知与机器语言之间的距离。这些定性特征要求各种评估人员减少偏见。因此，采用了相干措施。关键字循环经济（CE），多准则决策（MCDM），模糊共识，模糊加权积。
