"Hub location problems" lie at the heart of network design planning in transportation and telecommunication systems. They are a challenging class of optimization problems that focus on the location of hub facilities and on the design of hub networks. Some research areas have attracted most attention over the last decade such as relaxing main assumptions and incorporating additional features of real life applications. Therefore, hub location problems have been modified consistently, leading to more realistic models. Application areas of HLPs in transportation and telecommunication systems are abundant. These include express package delivery, air freight and passenger travel, postal delivery, trucking, and rapid transit systems, data transmission and network utilization. In this session, we would like to focus on new areas in hub location problems including; hub location and routing; incomplete hub location and routing; capacitated models and competition.
