Weighted additive fuzzy goal programming-based decision support system for green supply network design

Green supply network design (GSND) requires trading off multiple objectives like cost, lead time, and environmental impact. These objectives may be in conflict with each other as well as being vague when their target values (goals) are specified with different weights corresponding to supply chain strategies. The multiple conflicting objectives are optimized by using Goal Programming (GP). GP integrates with Fuzzy set theory (FGP) to address the goal vagueness and Weighted Additive operator (WAFGP) to allow decision makers differently emphasizing the goals. The WAFGP-based Decision Support System (DSS) for GSND contributes to the Pareto-optimal cost, lead time, and environmental impact in correspondence with supply chain strategies.
