Fuzzy AHP based Plant Sustainability Evaluation Method

Plant Sustainability has gained much prominence in the field of manufacturing in the recent past which has led to develop generic methodologies for plant sustainability evaluation. Wide focus has been given to environmental and economic aspects than the social domain in majority of them. It is rare to find that, the generic methodologies are capable of detail analysis especially when taken into account quantitative and qualitative factors which is commonly available among social domain. This paper presents a generic model to evaluate manufacturing plant sustainability using Fuzzy Analytic Hieratical Process (AHP). Since, social aspects frequently lead to qualitative evaluations of the experts, fuzzy logic has been used to convert the qualitative judgments into evaluable numbers, allowing Fuzzy AHP to perform an all-inclusive analysis. Moreover, the paper proposes a tool that can perform analysis at variable resolutions of available plant data. This variable resolution tool will allow evaluation to be carried out on feasibility studies on existing plants.
