Propagating Uncertainty in Life Cycle Sustainability Assessment into Decision-Making Problems: A Multiple Criteria Decision Aid Approach

Abstract

Life cycle sustainability assessments (LCSA) are a comprehensive source of information on product performance to support decision-making processes toward sustainable production and consumption. Multiple criteria decision aid (MCDA) approach provides a structured decision modelling that considers the value judgments of the decision-makers and it has been proved to be useful to support decision-making based on LCSA results. We proposed an approach able to take into account LCSA performances when making decisions. We applied our approach through a case study of tire life extension scenarios selection. The scenario with retreading is the solution that offer the best compromise between the three sustainable dimensions with more than 63% probability to rank first for Weighted sum, Topsis and Prométhée II MCDA methods.
