The work carried out in this research effort to identify and prioritize/rank the indicators to develop a framework for assessing the sustainability in energy planning and management for Indian energy sectors. Whilst, prioritizing the indicators is a kind of multi-criteria analysis decision. And, there are several difficulties in the process of prioritizing the indicators owing to the presence of vagueness and lack of clarity in the data. Thus, a fuzzy-based Analytic Hierarchy Process (AHP) approach is used in this research work [28]. The fuzzy AHP extends the AHP for decision making to cases carried out in an uncertain and fuzzy environment. Hence, it has the ability or advantage to deal with the uncertainty of human judgments not only in establishing the importance weights of the indicators [29], but also in prioritizing or ranking indicators in assessing the sustainability in energy planning and management.
