The article presents the memetic SOM, an evolutionary algorithm embedding self-organizing maps as operators to address the vehicle routing problem with time windows (VRPTW). We show that it allows to extend the self-organizing map to deal with a version of the vehicle routing problem with time windows where the number of vehicles is an input, and by adding(More)
Location-Routing Problem (LRP) can model several life situations. In this paper we study The Capacitated Location Routing Problem (CLRP) which is defined as a combination of two problems: the Facility Location Problem (FLP) and the Vehicle Routing problem (VRP). We propose a two-phase approach to solve the CLRP. The approach is based on Simulated Annealing(More)
In this article we study the capacitated location routing problem (CLRP) which is defined as a combination of two problems: the facility location problem (FLP) and the vehicle routing problem (VRP). The CLRP is not just a purely academic construct; it has many applications in the practice. We propose a hybrid approach based on a tabu search algorithm(More)
In most developed countries, life expectancy has been increasing steadily and burden of chronic disease continues to grow. The chronic diseases are responsible for increasingly growing health spending. Telemonitoring systems provide a way to monitor patients and their needs within the comfort of their own homes. In the first systems, the data were sent(More)
Nowadays, telemonitoring systems are increasingly used, due to the increasing of life expectancy and chronic diseases. Indeed, chronic diseases and disabilities due to advancing age are responsible for health care costs increasingly growing. Telemonitoring systems provide a low cost way to monitor patients and their needs in the comfort of their own homes.(More)
— Emergency situations require specific needs in particular in terms of communications, data transmission and sharing. Of particular concern are the transmissions of the patient's medical history to the emergency physician, the transmission of medical streaming data collected by devices (ECG, stethoscope …) to the emergency services. This will make it(More)
