In this paper we consider service-oriented applications composed of component services provided by different, economically independent service providers. As in all composite applications, the component services are composed and configured to meet requirements for the composite application. However, in a field experiment of composite service-oriented applications wef found that, although the services...
One of the biggest drivers behind IT-based homecare solutions is the increasing aging population. We are specifically interested in “service tailoring” for the homecare domain, where healthcare professionals (care-givers) do the tailoring of services to support elderly (care-receivers). Our goal is that, using our approach, care-givers can create or modify services with less IT skills, time and/or...
In a service-oriented architecture, adaptive and evolvable applications should be able to select, configure and compose different existing application services to deal with the changes which can arise from runtime contextual changes or the change of user requirements and preferences. To support this, hybrid service composition approaches have been proposed, in which the core of application logic,...
The realization of homecare services is difficult because of dynamicity requirements and constraints that exist in this domain. These requirements call for a dynamic service provisioning, i.e., adaptivity and adaptability of the (composition of) homecare services in response to a) frequently occurring changes like change in the location or vital signs, or b) slowly developing changes like extent of...
In most of the industrialized countries, the aging of the population dramatically progress rapidly. This trend demands economically feasible solutions to provide care to elderly, preferably at their home. IT can play an important enabling role in such solutions. Previously, we proposed an approach for personalizing IT-based homecare services by introducing a tailoring process. The tailoring process...
Dynamicity is one of the main challenges in providing sustainable solutions for the homecare domain. The dynamicity of homecare systems, caused by external entities like care-receivers and care-givers, can be addressed through combining distributed and heterogenous services both in design and runtime. In general, several research fields such as dynamic service composition, context-aware service composition...
One of the conditions for the successful introduction of ICT-based homecare services is to allow non-technical persons such as home nurses to personalize these services. We refer to this process of homecare service personalization as service tailoring. Service tailoring can be done by configuring and composing previously developed and deployed service building blocks. In this paper, we describe an...
Health monitoring and healthcare provisioning at home (i.e., outside the hospital) have received increasingly attention as a possible and partial solution for addressing the problems of an aging population. There are still many technological issues that need to be solved before home healthcare systems can be really cost-effective and efficient. However, in this paper we will highlight another category...
