Connected facility location combines cost-efficient facility placement and the requirement to connect the facilities among each other. Such problems arise, e.g., in telecommunication applications where networks consist of a central core and local clients connected to it. Reliability of the core is a central issue, and we may hence require the core to be at least 2-connected. We establish the pr...

Many types of facility location/allocation models have been developed to find optimal spatial patterns with respect to location criteria such as: cost, time, coverage, and access. In this paper we develop and test location modeling formulations that utilize aspects of the data envelopment analysis (DEA) efficiency measure to find optimal and efficient facility location/allocation patterns. Solv...

The amount of the conventional energy sources is decreasing day by day. Here in Bangladesh, the main source of energy generation is natural gas. To avoid the upcoming energy crisis, we need to incorporate the renewable energy sources with which Bangladesh is blessed due to its geographical location. Bangladesh has a very good prospect for the solar Photovoltaic integration. The technical potent...

Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....

Abstract Location cover models are aimed at siting facilities so as to provide service demand efficiently. These crucial in the management, planning and decision-making of systems public private sectors. As a result, location have been incorporated range GIS tools, either closed or open source. Among them, open-source tools advantageous due transparency reproducibility. Nonetheless, capabilitie...

Location-based routing protocols are stateless since they rely on position information in forwarding decisions. However, their efficiency depends on performance of location services which provide the position information of the desired destination node. Although several location service schemes have been proposed, their main goal is merely to find the location of the destination node. Seldom th...

The optimal locating of facilities has large effects on economic benefits, providing satisfactory service and levels of customer satisfaction. One of the new topics discussed in location problems is hub location and hub facilities are subject to unpredictable disruptions. This paper proposes a nonlinear integer model for reliable single allocation hub location problem that considers backup hub,...
