Cross-Border Fulfillment Center Selection via Doubly Robust Estimation and Linear Programming

arXiv:2611.14174v1 Announce Type: new Abstract: We introduce the cross-border (XB) fulfillment center (FC) Selection Model: a multi-stage optimization framework combining forecasting, doubly robust estimation, and linear programming to select optimal source FCs.
