Solution to multi-objective hub location problem using evolutionary algorithms-an application to ptt network

Çamlar, Onur
In this study, we consider the hub location problem of PTT, first realized by Cetiner (2003), and propose the evaluation of multiple decision criteria while locating hubs. Since the mathematical model for the problem is too large to be solved, we utilize heuristic methods in the solution procedure. While doing this, we first test two algorithms, NSGA-II and SPEA2, on different hub location problems and use the algorithm with better performance while solving the PTT problem.
