SOLVING A NEW P-HUB LOCATION MODEL FOR MEDICAL EMERGENCY SITUATIONS BY PARTICLE SWARM OPTIMIZATION

Hubs are special facilities that serve as switching, transshipment and sorting points in manyto- many distribution systems. The p-hub location problem is concerned with locating p-hub facilities and allocating demand nodes to hubs in order to route the traffic between origin– destination pairs. In this paper, we introduce a p-hub location model for medical emergency situations and after clarifying accuracy of the model in GAMS, and due to the fact that this problem has very long processing times with exact approaches for large sizes, we solve the presented model using particle swarm optimization (PSO).
