In this paper, a single-source capacitated multifacility location problem with rectilinear distance under unbalanced transportation constraints is studied. The problem is formulated as a mixed integer linear programming problem of which the objective function is the sum of nonlinear functions. An algorithm under decomposition approach combining with logic based techniques is developed. Using th...

A single facility problem in the plane is considered, where an optimal location has to be identified for each of finitely many time-steps with respect to time-dependent weights and demand points. It is shown that the median objective can be reduced to a special case of the static multifacility median problem such that results from the latter can be used to tackle the dynamic location problem. W...

Acinetobacter baumannii is a ubiquitous pathogen capable of causing both community and health care-associated infections (HAIs), although HAIs are the most common form. This organism has emerged recently as a major cause of HAI because of the extent of its antimicrobial resistance and its propensity to cause large, often multifacility, nosocomial outbreaks. The occurrence of outbreak is facilit...

The EU H2020 MaRINET2 project has a goal to improve the quality, robustness and accuracy of physical modelling associated testing practices for offshore renewable energy sector. To support this aim, round robin scale test programme was conducted deploy common wave converter at four basins operated by partners. Test campaigns were each facility specification matrix, providing unique opportunity ...

BACKGROUND Catheter hub decontamination requires a thorough scrub and compliance varies. This study evaluates the effectiveness of a disinfection cap with 70% alcohol in preventing contamination/infection. METHODS A 3-phased, multifacility, quasi-experimental study of adult patients with central lines divided into P1 (baseline), when the standard scrub was used; P2, when the cap was used on a...

Good heuristic solutions for large Multisource Weber problems can be obtained by solving related p-median problems in which potential locations of the facilities are users locations and then solving Weber problems for the sets of users of each facility. Weber's problem is to locate a facility in the Euclidean plane in order to minimize the sum of its (weighted) distances to the locations of a g...

OBJECTIVE This quality improvement (QI) project was initiated to understand what differentiates nursing homes (NHs) that perform well on publicly reported Centers for Medicare and Medicaid Services (CMS) Quality Measures (QMs). The intent was to assist NH staff to direct QI efforts to positively impact QM rates. A key step was to determine if any resident or facility characteristics might accou...
