This paper presents a multi-objective and multi-service location-allocation model with capacity planning to design a healthcare facilities network through considering a referral system. Therefore, a mixed integer nonlinear programming (MINLP) model containing two objective functions is proposed. The first objective function is  relates to minimization of total opening cost, minimization of tota...

This article presents the design of a system for monitoring temperature and humidity for the prevention of forest fires using wireless sensor networks. An initial study of the causes of Forest Fires, like how to prevent them is necessary have a clear idea of how to implement a valid network design that is capable of detecting possible changes in the environment, in that way we can prevent a dis...

Adherence to the policy guidelines and standards is necessary for family planning services. We compared public and private facilities in terms of provision of family planning services. We analyzed data from health facility questionnaire of the 2006 Tanzania Service Provision Assessment survey, based on 529 health facilities. Majority of public facilities (95.4%) offered family planning services...

We study the problem of navigating through a database of similar objects using comparisons under heterogeneous demand, a problem closely related to small-world network design. We show that, under heterogeneous demand, the small-world network design problem is NPhard. Given the above negative result, we propose a novel mechanism for small-world network design and provide an upper bound on its pe...
