In this research, a hierarchical location-allocation problem is modeled in a queue framework. The queue model is considered as M/M/1/k, in which system capacity is finite, equals to k. This is the main contribution of the current research. Customer's enters to the system in order to find the service according to a Poisson. In this problem, the hierarchical location-allocation model is considere...

In this paper, we have proposed a new genetic algorithm for p-median location problem. In this regard, prior genetic algorithms were designed for p-median location problem by proposing several methods that are used in generation of initial population, crossover and mutation operators, and new operator socalled re-allocation has been incorporated into the algorithm that causes to find the optima...

The deployment of edge computing infrastructure requires a careful placement the servers, with an aim to improve application latencies and reduce data transfer load in opportunistic Internet Things systems. In server placement, it is important consider capacity, available budget, hardware requirements for servers underlying backbone network topology. this paper, we thoroughly survey existing li...

Location-allocation modeling has always been regarded as a core part of spatial analysis. A review the literature, however, reveals that, nevertheless, publications related to facility location disappeared almost completely from geographic journals in meantime. It can be assumed that one major reason for this development is limited capability location-allocation modules implemented GIS packages...

With the ever increasing number of functional similar web services being available on the Internet, the market competition is becoming intense. Web service providers realized that good Quality of Service (QoS) is a key of business success and low network latency is a critical measurement of good QoS. Because network latency is related to geometric location, a straightforward way to reduce netwo...
