We follow [18,25] and give a series of improved results for the Constrained Fault-Tolerant Resource Allocation (FTRA) problem. In FTRA, we are given a set of sites containing facilities as resources, and a set of clients consuming these resources. Specifically, each site i is allowed to open at most Ri facilities with cost fi for each opened facility. Each client j requires an allocation of rj ...

BACKGROUND AND METHODS Knowledge of utilization of health services and associated factors is important in planning and delivery of interventions to improve health services coverage. We determined the prevalence and factors associated with health services utilization in a rural area of Kenya. Our findings inform the local health management in development of appropriately targeted interventions. ...

In a resource-constrained society in developing nations like India, the importance of health care infrastructure allocation is often undermined and overlooked. This paper aims to quantify the gap in accessing affordable health care facilities faced by the socio-economically weaker sections of society. Majority of the older cities in India have a central core and surrounding peri-urban areas, wh...

BACKGROUND Precise quantification of health service utilisation is important for the estimation of disease burden and allocation of health resources. Current approaches to mapping health facility utilisation rely on spatial accessibility alone as the predictor. However, other spatially varying social, demographic and economic factors may affect the use of health services. The exclusion of these...

Objective To evaluate the implementation of a time-driven activity-based costing analysis at five community health facilities in Haiti. Methods Together with stakeholders, the project team decided that health-care providers should enter start and end times of the patient encounter in every fifth patient's medical dossier. We trained one data collector per facility, who manually entered the ti...

First, we study the Unconstrained Fault-Tolerant Resource Allocation (UFTRA) problem (a.k.a. FTFA problem in [19]). In the problem, we are given a set of sites equipped with an unconstrained number of facilities as resources, and a set of clients with setR as corresponding connection requirements, where every facility belonging to the same site has an identical opening (operating) cost and ever...

BACKGROUND The low proportion of health facility delivery in developing countries is one of the main challenges in achieving the Millennium Development Goal of a global reduction of maternal deaths by 75% by 2015. There are several primary studies which identified socio-demographic and other predictors of birth in health facility. However, there are no efforts to synthesis the findings of these...

In many service and industrial applications of the facility location problem, the number of required facilities along with allocation of the customers to the facilities are the two major questions that need to be answered. In this paper, a facility location problem with stochastic customer demand and immobile servers is studied. Two objectives considered in this problem are: (1) minimizing the ...
