A subjective multi-criteria assessment of the lean and green production by using hesitant fuzzy sets

Lean Production, which has been implemented in a wide range of areas for many years, mainly aims to meet customer satisfaction while reducing waste and keeping efficiency at the maximum level. The Green Production tries to minimize the negative impact of production on environment while to increase the efficient utilization of natural resources. The analogy of these two concepts may sometimes encourage the joint application. Analysis of the factors affecting the success of Lean and Green production requires a multi-dimensional evaluation of experts as either researchers or practitioners. In this way, the problem on hand becomes a typical multi-criteria decision making problem and also contains uncertainty inherent in subjective evaluation of decision makers. Due to this reason, this study presents a fuzzy multi-criteria evaluation methodology by using hesitant sets. A real life application of the approach which considers the case of Türkiye is also presented.
