In emergency medical facilities location, the hierarchical diagnosis and treatment system plays an obvious role in rational allocation of resources improving use efficiency resources. However, few studies have investigated operational mechanism systems uncertain environments. To address this research gap, paper proposes a hybrid approach for facilities’ location-allocation. first stage, order t...

As much as 40% of live biomass in coniferous forests is located belowground, yet the effect of tree density on biomass allocation is poorly understood. We developed allometric equations using traditional harvesting techniques to estimate coarse root biomass for ≈13-year-old postfire lodgepole pine trees (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.). We then used these equations, plus ...

Location analysis has so far been limited to spatial, and in some cases spatio-temporal, constraints. For example, the optimal site for a shopping center can be determined by taking the location of other centers and of potential customers into account, and factoring in transportation networks, as well as land use and zoning restrictions. Some solutions, like the relatively unknown but seminal w...

The main purpose of any facility location is to select the optimal places that satisfy project's goals. In location problems, the object is usually to optimize a function objective function that defines the problem conditions and efficient decision parameters. Numerous methods are proposed to challenge the location facility issues. In this paper, we consider a class of location/allocation probl...

BACKGROUND The esophagus may be mobile during a left atrial (LA) ablation procedure for atrial fibrillation (AF). OBJECTIVE The goal of the study was to determine whether the location of the esophagus is stable in patients undergoing a repeat LA ablation procedure. METHODS Forty-two patients underwent repeat LA ablation a mean of 7 +/- 2 months after the initial procedure. Cinefluoroscopic ...

Flood management can be defined as the technique and strategy to reduce risk damage from flooding. The efficient strategies for both short-term long-term plans is needed in order minimise losses during disaster happen. governance entails need of a coordinated system dealing with this natural disaster. phases flood cycle such preparedness, mitigation, Emergency Response Plan (ERP), recovery help...

Two hierarchical location-allocation models are used to locate two types of communitybased health facilities in Davao City, Philippines. Oftentimes, locating health facilities are motivated by factors such as politics and resource availability. Different optimization approaches to locating a mix of these health facilities across the rural and urban areas of the city. Computations results are ev...

7he T economics i off introducing ultrafiltration (UF) ) into the Ontario i dairy industry is analyzed. . First, t, a partial budget is developed to determine feasibility off UF on the farm. . The budget indicates that the great majority off Ontario dairy farms are not large enough to capture the economies off size inherent in the new technology. l y. Second, , a location-allocation ll ti model...

A new location update strategy for personal communication services (PCS) networks and its implementation using a genetic algorithm are proposed. Most of the practical cellular mobile systems partition a geographical region into location areas (LAs) and users are made to update on entering a new LA. The main drawback of this scheme is that it does not consider the individual user mobility and ca...
