Optimizing multi-layer merge-in-transit supply chains
Department of Civil and Environmental Engineering, Center for Cyber-Physical Systems
The authors propose an integer programming model formulation and solution algorithm to model a multi-layer supply chain network for merge-in-transit pool operations. The model explicitly describes individual small size shipment transportation decisions on choosing merge-in-transit pool strategies and pool centers in a multi-carrier supply chain network. The model subjects to a set of merge-in-transit pool operation constraints at in-transit pool centers for orders from multiple origins and destinations, which do not require to hold inventory at pool centers but require simultaneous arrivals. To solve large-scale applications, the authors develop a logic-based Benders decomposition algorithm in a branch-and-bound framework that can deal with subproblems of integer programs. The authors demonstrate the effectiveness of the proposed algorithms in two supply chain networks.
