A fuzzy multi-criteria approach for evaluating biofuels feedstocks

In this paper, we develop a fuzzy holistic approach evaluating the conventional and advanced biofuels feedstocks in meeting multiple economic, environmental and social criteria of the biofuels policies and capturing the uncertainties of policy evaluation and design processes. We use a multi-criteria approach PROMETHEE (Preference Ranking Organization METHod for Enrichment Evaluations) and fuzzy set theory to show how missing information, fuzziness, and ambiguity in decision making processes can be internalized in the process of creating a sustainable biofuels policy.
