“…A service plan consists of one or more service building blocks (SBBs) and describes the configuration and orchestration of instances of these service building blocks with respect to run-time circumstances. The service plan specifies the behavior of a composite application at runtime by specifying which application service will be selected for a SBB and how the selected service will be configured and orchestrated [21] . Each service plan can have several predefined orchestrations (of SBBs) of which one is selected at runtime based on decision making rules.…”

Abstract. Providing IT-based care support for elderly at home is proposed as a highly promising appraoch to address the aging population problem. With the emergence of homecare application service providers, a homecare system can be seen as a linked set of services. Configuring and composing existing homecare application services to create new homecare composite applications can reduce the application development cost. The idea even looks more promising if the service provisioning is dynamic, i.e., if applications can update their behaviors with respect to the contextual changes without or with minimum manpower. Dynamic service provisioning can play an important role to accept homecare systems in practical settings. This motivated us to develop a Dynamic Homecare Service Provisioning (DHSP) platform to address the homecare context changes in an effective and efficient manner. As a proof of concept, we have developed a software prototype of our platform. The prototype was subsequently used in a real-world field test at a care institution in the Netherlands to validate the approach. This paper describes the design of the field test and reflects on the outcome of the validation experiments.

“…1 presents the V-Care system. The V-Care system comprises three main platform components which are: (a) a tailoring plat form (to enhance creation of the service plans by care-givers), (b) a provisioning platform (to execute the service plans, and to integrate and orchestrate the application services as required by the service plans) [16] and c) a service repository platform (a collection of application services). Some of these application services are implemented by the V-Care system such as reminder, calendar and alert services, while others are implemented by third-party providers outside the V-Care system, such as blood pressure monitoring and medication dispensing services.…”

Abstract-One of the biggest drivers behind IT-based home care solutions is the increasing aging population. We are specif ically 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 effort, and care-receivers get services that are better suited for their specific and personal needs. As a proof of concept, we developed a software prototype of our approach.The prototype was subsequently used in a real-world field test at a care institution in the Netherlands to validate the approach.The validation focused on the usability aspects of the approach in terms of effectiveness, efficiency, learnability and satisfaction. This paper describes the design of the field test and reflects on the outcome of the validation experiments.

“…A service plan refers to one or more service building blocks (SBBs) and describes the configuration and orchestration of these SBBs as well as decision rules required to specify runtime behaviour [6]. The application starts based on a predefined calendar event and reminds Jan, possibly several times, to measure his blood pressure.…”

“…A process logic usually incorporates or has an associated set of (declarative) rules to specify the conditions and constraints on the imperative flows. Since both processes and rules have advantages and disadvantages on their own rights, hybrid service composition (which uses a combination of processes and rules) has been proposed as a plausible solution to support evolvability [5], [6], [7], [8], [9], [10]. However, a process logic can be implemented in rules and some of the rules can be implemented in processes, and finding a balance of what can be specified by the process logic and what by the rules is a serious challenge [11].…”

“…In this paper, based on our earlier work [6], we design an adaptive service provisioning architecture using the decision service allowing both synchronous request-response interaction and asynchronous notification. Accordingly, we define a decision service template for the decision service which specifies its service interfaces and the corresponding input and output message exchange patterns.…”

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, which is rather stable, is specified in terms of processes while rules are employed to specify the conditions and constraints to adapt the application behaviour. The rules are then exposed as a decision service which can be employed by the process to make adaptation decision with respect to runtime circumstances. The interaction between processes and decision services are generally performed in synchronous request-response manner. We argue that such an interaction is not efficient to support different types of adaptation at runtime and therefore asynchronous interaction should also be supported. In this paper, we present an adaptive service provisioning architecture and a decision service template allowing both synchronous request-response interaction and asynchronous notification. To motivate the proposed architecture and the decision service template, we use a blood pressure monitoring scenario from the homecare domain. We also explain the implementation of the proposed approach based on commercially available rule and process engines. Finally, we discuss: 1) what is the efficient way (synchronous request-response interaction vs. asynchronous notification) of calling decision service to execute different types of decision rules? and 2) to what extent the use of decision service facilitates dealing with the unforeseen changes?
