Assessment of Green Sustainability Index of a Machining Process Using Multigrade Fuzzy Approach

Abstract

This paper focuses on assessing the environmental sustainability of a machining process. Environmental sustainability involves production of products by eco-friendly methods assuring a green environment. A sustainability assessment model is presented considering the green characteristics of a machining operation in three orientations: productivity, environmental performance, and economic performance using multigrade fuzzy approach. The area which needs improvement in the sustainability level of a process is identified, and proposals are given which assists the industrialists to remain competitive ensuring a green environment. The usage of this model will accelerate the green practices in machining process.
