Achieving Flexible Process Interoperability in the Homecare Domain through Aspect-Oriented Service Composition

Abstract

In elderly care the shortage of available financial and human resources for coping with an increasing number of elderly people becomes critical. Current solutions to this problem focus on efficiency gains through the usage of information systems and include homecare services provided by IT systems. However, the current IT systems that integrate homecare services have difficulties in handling the user-context dynamicity and the diversity of needs and preferences of care-receivers. This makes the available homecare services hardly interoperable at the process level, particularly due to the lack of support for process flexibility. In this paper, we present an approach capable of dealing with such interoperability issues based on aspect-oriented service composition. We demonstrate the feasibility of our approach and of the proposed architecture by implementing a prototype for a reminder service scenario.

Rule- and context-based dynamic business process modelling and simulation

“…The other columns indicate the requirements and to what extent the given approach covers each requirement. (Bui et al, 2013)). We make a presumption that it is an external context, since the most variables belongs on concrete situation (i.e.…”

“…Therefore, it is not clear which part of the method/approach is implemented. Though authors like Bui et al (2013), Yao et al (2012), Döhring et al (2010), PROVOP and Boukhebouze et al (2011) present prototypes and some print screens that enhance the proposed approaches, no author presents a process simulation.…”

“…Contrary, other approaches are based on an initial process model that limits the dynamicity and BP can be changed only in predefined places in a process -e.g. variation points, like in (Eijndhoven et al, 2008;Bui et al, 2013) or pointcuts, like in (Hermosillo et al, 2010a,b).…”

“…Rather, it executes already known alternative processes after detecting predefined situations. The authors Bui et al (2013) propose a SOA-based architecture for their approach implementation. The main components of the architecture -implementing dynamic workflows -are described as follows.…”

“…Comparison of the eleven approaches on rule-and context-based DBP modelling and simulation The authorsBui et al (2013),Yao et al (2012) identify user-context, which can be described by a set of variables characterizing the user's needs (i.e. time of taking medications, blood pressure, etc.…”
