The Global Upstream Planning (GUP) system—now known as SCOUT—was developed by the World Food Programme (WFP) as a global-scale optimization tool for upstream supply chain decision‑making. SCOUT uses optimization AI to enhance global food sourcing and delivery planning for WFP's supply chain. It optimizes complex supply chain planning by modeling WFP's global supply chain network, focusing on upstream operations up to recipient countries. It provides data-driven insights to improve decision-making in sourcing and delivery planning for HQ core units and regional bureaux.
