In order to ensure that end of life vehicles (ELVs) are discarded without endangering the environment, appropriate collection systems should be set up. In accordance with the European Community Directive, the construction of an industrial plant for the decontamination and recycling processes of ELVs is currently being planned in Navarra (Spain). The aim of(More)
This paper describes a methodology which combines elements of statistics, probability, mathematical programming, simulation, multiobjective optimization and metaheuristics, to analyze management problems in a health care context. We apply this approach to a staffing problem in a primary care center, taking into account both cost and service quality(More)
In a previous paper, we developed an accurate simulation model of an Intensive Care Unit to study bed occupancy level (BOL). By means of accurate statistical analysis we were able to fit models to arrivals and length-of-stay of patients. We model doctors' patient discharge decisions and define a set of rules to determine the conditions for earlier or(More)
This paper deals with the management of scarce health care resources. We consider a control problem in which the objective is to minimize the rate of patient rejection due to service saturation. The scope of decisions is limited, in terms both of the amount of resources to be used, which are supposed to be fixed, and of the patient arrival pattern, which is(More)
In recent years, growing attention has been paid to the use of renewable resources to produce electricity. One of the main drawbacks of generating electricity through, say, wind power, however, is random input, which obviously results in random output. This means that peak output does not always coincide with peak demand. Nevertheless, demand drives prices,(More)
The aim of this article is to present the uses of operational research in the health sciences, both in the field of the organisation and management of health resources and in the field of prevention, detection and treatment of diseases. we concentrate on application, without entering into the technical details of the mathematical models or the methods of(More)
Physician's workload inequality in Emergency Departments (ED) is a relevant problem that affects their stress level, which influences the service quality and working conditions. The patient-physician assignment rule (PPAR) has a bearing on the physicians' workload, which has been studied in the Medical literature by performing interventions. These show(More)
