Hub Location, Routing, and Route Dimensioning: Strategic and Tactical Intermodal Transportation Hub Network Design

We propose a novel hub location model that jointly eliminates some of the traditional assumptions on structure network and discount as result economies scale in an effort to better reflect real-world logistics transportation systems. Our extends literature various facets: instead connecting nonhub nodes directly nodes, we consider routes with stopovers; pairs hubs directly, design can visit several nodes; rather than dimensioning pairwise connections, dimension vehicles; working homogeneous fleet, use intermodal transportation. Decisions pertinent strategic tactical are concurrently made through proposed optimization scheme. An effective branch-and-cut algorithm is developed solve realistically sized problem instances provide managerial insights.
