Domesticating Homecare Services; Vehicle Route Problem Solver Displaced

4. Discovering Homecare Services

Future homecare networks will consist of a very wide range of embedded services and software that will often rely on numerous other components to achieve their tasks. They will rarely operate in a self sufficient manner. The ability to discover and use services is not however a trivial task. Services may provide raw data, such as temperature readings, or higher contextual data, such as user act...

The Vehicle Routing Problem with Time Windows: Minimizing Route Duration

We investigate the implementation of edge-exchange improvement methods for the vehicle routing problem with time windows with minimization of route duration as the objective. The presence of time windows as well as the chosen objective cause verification of the feasibility and profitability of a single edge-exchange to require an amount of computing time that is linear in the number of vertices...

Service Tailoring: Towards Personalized Homecare Services

Health monitoring and healthcare provisioning for the elderly at home have received increasingly attention. Since each elderly person is unique, with a unique lifestyle, living environment and health condition, personalization is an essential feature of homecare software services. Service tailoring, which is creating a new service to meet individual requirements may be achieved in a cost-effect...

Problem Solver

The contract net protocol has been developed to specify problem-solving communication and control for nodes in a distributed problem solver. Task distribution is'affected by a negotiation process, a discussion carried on between nodes with tasks to be executed and nodes that may be able to execute those tasks. We present the specification of the protocol and demonstrate its use in the solution ...
