The design of hub-and-spoke transport networks is a strategic planning problem, as the
choice of hub locations has to remain unchanged for long time periods. However, strikes …

In this paper we review the integer linear formulations of the uncapacitated multiple
allocation hub location problem, we study the scope of validity of these formulations and …

A new compact formulation for uncapacitated single-allocation hub location problems with
fewer variables than the previous Integer Linear Programming formulations in the literature …

In this paper a well-known formulation for the capacitated single-allocation hub location
problem is revisited. An example is presented showing that for some instances this …

In this paper, we present a memetic algorithm (MA) for solving the uncapacitated single
allocation hub location problem (USAHLP). Two efficient local search heuristics are …

Hub-and-spoke networks are widely studied in the area of location theory. They arise in
several contexts, including passenger airlines, postal and parcel delivery, and computer and …

This paper deals with the uncapacitated multiple allocation hub location problem. The dual
problem of a four-indexed formulation is considered and a heuristic method, based on a …

In telecommunication and transportation systems, the uncapacitated multiple allocation hub
location problem (UMAHLP) arises when we must flow commodities or information between …

In this paper we consider and present formulations and solution approaches for the
capacitated multiple allocation hub location problem. We present a new mixed integer linear …

The uncapacitated single allocation hub location problem (USAHLP) is a particular variant of
the hub location problem, which has broad applications in the transportation network. The …
