A new multi-objective intermodal hub-location-allocation problem is modeled in this paper in which both the origin and the destination hub facilities are modeled as an M/M/m queuing system. The problem is being formulated as a constrained bi-objective optimization model to minimize the total...

The present paper deals with the problem of locating hubs for freight mobility in urban and suburban areas. In particular, we present a heuristic method that combines aspects coming from both classical simple plant location problems and shortest path ones on multimodal graphs. In the first phase...

Hub-and-spoke designs are frequently used in many types of transportation and communication networks. The challenge to academics is to develop effective solution procedures for determining the number of hubs, locating hub facilities and allocating the non-hubs to the hubs. In this note, we deal...
