Abstract

This article proposes a mixed integer non-linear programming model for the optimizing supply chains of importers of waterborne containerized goods from Asia to the USA. This model determines the least-cost strategy for an importer, in terms of ports and landside transportation modes to be used, where costs considered include costs for transportation and handling, pipeline inventory, and safety-stock. We introduce a heuristic algorithm to quickly solve the mathematical model to near optimality. We assess the proposed heuristic compared to use of a commercial solver, and provide general recommendations for efficient supply-chain strategies as a function of the value of imported goods.

Research highlights► Allocation of containerized imports to ports and landside transportation modes. ► Determines safety-stock inventories as a function of lead time mean and variation. ► Minimizes total costs to importer for transportation, handling and inventory. ► Heuristic algorithm solves mixed integer non-linear program to near-optimality. ► Best supply-chain strategy as a function of declared value and holding cost rate.
