Developing prevention reliability in hub location models

Hub location problem has been one of the most interesting areas of location problems in recent decades. Hubs are critical centers that have a significant role in networks such as logistic, distribution and transportation networks. Therefore, it is necessary to design reliable hub networks to overcome different interruptions. In this article, we have proposed a new concept in hub location problems called preventive reliable hub location problem which is based on passive defense definitions. When valuable objects are transported via networks, many intentional crimes such as attack or robbery may occur. To make transportation faster and cheaper, it is desired to use hub and spoke networks. In addition, preventive reliable hub location problem is designed to secure the network and prevent loss of values. To make the network more reliable and save all common properties, three new objects have been added to the usual hub networks: fake hub, fake allocation and fake flow. A mixed integer linear programming is used to model preventive reliable hub location problem and solved using literature data. Finally, the results are represented.
