Capacitated Multiple Allocation Hub Covering Flow Problem
Abstract
optimal design for hub-and-spoke networks while taking into account hub opening and demand
routing costs. Every network node has the potential to be a hub and demand from an origin to a
destination must be sent through at least one hub. The network is incomplete in the sense that
the maximum allowed or coverage distance between any opened hub and demand origin/
destination is predefined. It is assumed that there is a cost saving to route demand via hubs due
to consolidation. Another important issue is the consideration of capacity restrictions imposed
on network links and opened hubs. The problem is developed as a mixed-integer linear
optimization problem. According to the results obtained from computational experiments, we
show that taking into account both flow related costs and capacities of network components
concurrently is very important to have a cost effective design.
