چکیده مقاله:
The hierarchical hub covering facility location problems are applied to distribution systems,transportation, waste disposal, treatment services, emergency services and remote communication. Theproblems attempt to determine the location of service providers' facilities at different levels and specifytheir linking directions in order to reduce costs and to establish an appropriate condition in distribution network. By utilizing these problems, the present paper attempts to allocate capacitated option to each provider service and consequently establish and choose the best possible condition, so thatdemands centers are rationally and effectively guided by service providers' centers and their request never remains without response. To do this, the model the capacitated single allocation hierarchical hub median location problem is developed, created and provided. In addition, considering of theincreasing demand, modulating choices are addressed in order to fulfill the future needs and to impose uncertainty in decision making in the results. To validate the model, we used IAD data, which the results confirm its consistency.
