Hub location problem is an NP-hard problem that frequently arises in the design of transportation and distribution systems, postal delivery networks, and airline passenger flow. This work focuses on the Single Allocation Hub Location Problem (SAHLP). Genetic Algorithms (GAs) for the capacitated and uncapacitated variants of the SAHLP based on new chromosome representations and crossover operators are explored. The GAs is tested on two well-known sets of real-world problems with up to 200 nodes. The obtained results are very promising. For most of the test problems the GA obtains improved or best-known solutions and the computational time remains low. The proposed GAs can easily be extended to other variants of location problems arising in network design planning in transportation systems.

The “Persia” was built in St. Catharines in 1873. From 1877 to 1894 the ship was owned by James Norris of St. Catharines. The Toronto and Montreal Steamboat Co. acquired the ship in 1894, followed by the Quebec Navigation Co. in 1907. A fire severely damaged the ship in 1911, and the following year the “Persia” was rebuilt as a barge.
