Abstract
Enterprises have been increasingly forced to consider broader aspects while designing and manufacturing products. The scarcity of natural resources plus sterner environmental regulations have obliged enterprises to develop new products that can satisfy profit, people, and planet during their life cycles. During the last decade, numerous research efforts have incorporated supply chain and sustainability factors into product design. However, most of these studies have generated deterministic based methodologies. Enterprises intending to improve sustainability under uncertainties have been left without an appropriate method of analysis. This study presents a method based on fuzzy set theory intended to tackle uncertainty in the supply chain and to highlights sustainable design concepts involving product disassemblability, supply chain network cost, lead time, and carbon footprints. The sustainability of both the product and the supply chain are considered at the product design stage. A case study demonstrates the advantage of this methodology.
