The current duration of a link in a mobile wireless ad hoc network (MANET) can be used for link stability assessment through on-line remaining link life estimation. These estimates implicitly include the effects of true propagation mechanisms, mobility space geometry, power control mechanisms and other phenomena that are ignored or simplistically modeled in other methods based on location or si...

different decisions, including location decisions of companies which are operating in international dynamic environment are subject to significant uncertainty.so in this research an international facility location problem under uncertainty is considered and an integrated model for strategic and operational planning is presented. in strategic level countries are assessed according to internation...

In this paper we introduce a new facility location model, called backup multifacility location problem by considering the ideal radius for each customer. In this problem the location of clients are given in the plane. A radius is assigned to each client. We should find the location of new facilities, which some of them may fail with a given probability, such that the sum of weighted distances f...

Abstract In this article, we present the process and results of using quantum computing (QC) to solve maximal covering location problem proposed by Church ReVelle. With contribution, seek lay foundations for other urban regional scientists begin consider technologies. We obtained promising results, but it is clear that there a need more capable devices with qubits less susceptibility electronic...

Abstract One of the basic assumptions in hub covering problems is considering the covering radius as an exogenous parameter which cannot be controlled by the decision maker. Practically and in many real world cases with a negligible increase in costs, to increase the covering radii, it is possible to save the costs of establishing additional hub nodes. Change in problem parameters during the pl...
