Solving multifacility Huff location models on networks

E consider multifacility Huff location problem on networks. This mixed integer nonlinear optimization problem is solved using three metaheuristics: Variable Neighborhood Search, Simulated Annealing and Multi-Start Local Search. Computational experience is reported. We also propose a mathematical model for solving the problem exactly.e consider multifacility Huff location problem on networks.
