In this paper, the problem of determining the optimum number and locations of banking automatic teller machines (ATMs) is considered. The objective is to minimize the total number of ATMs to cover all customer demands within a given geographical area. First, a mathematical model of this optimization problem is formulated. A novel heuristic algorithm with unique features is then developed to eff...

discrete facility location,   distribution center,   logistics,   inventory policy,   queueing theory,   markov processes, the distribution center location problem is a crucial question for logistics decision makers. the optimization of these decisions needs careful attention to the fixed facility costs, inventory costs, transportation costs and customer responsiveness. in this paper we study t...

Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...

Mobile agents have the ability to migrate through heterogeneous networks and execute at remote hosts. This ability can be exploited to improve the performance of agent based applications by transferring agents to less heavily loaded hosts or by adapting the client/server interactions to the network load. That is, rather than transferring raw data through a bottleneck link, a small sized agent m...

Wastewater treatment technology in the cyclic nature of the process that takes a long time. But man tries to rush to their needs with experience and understanding of the natural processes of interaction, and using technology to build their Industrial development is authorized. Sewage treatment reed have been born from the vision of man's increasing need to water daily decreases the natural reso...

pay attention to the public transportation, cycling and pedestrian oriented development (pod) and car-free streets can increase the quality of urban spaces and create more secure pedestrians with psychological comfort for human. old urban fabric with hidden physical, historical, and cultural values has been the best evidence of urban identity and meanwhile, the life and growth of this fabric ha...

In this paper, a new variant of the Simple Plant Location Problem is proposed. We consider additional conditions in classic location-allocation problem for clients and facilities. Namely, some pairs have to be served by common plant. The resulting can addressed with existing models case single assignment. However, best our knowledge, proposed setting when each client must assigned couple facili...
