A number of concerns in multi-agent system (MAS) design have a crosscutting impact on agent-oriented models. These concerns inherently affect several system agents and their internal modeling elements, such as actions and goals. Examples of crosscutting concerns in MAS design encompass both internal and systemic properties, such as learning, mobility, error handling, and security. Without an ex...

Service-oriented computing has become the de-facto way of developing distributed applications and, in such systems, an accurate assessment of reputation is essential for selecting between alternative providers. Existing methods typically assess reputation on a combination of direct experiences by the client being provided with a service and third party recommendations, but they exclude from con...

An aspect-oriented design model consists of a set of aspect models and a primary model. Each of these models consists of a number of different kinds of UML diagrams. The models must be composed to identify conflicts and analyze the system as a whole. We have developed a systematic approach for composing class diagrams in which a default composition procedure based on name matching can be custom...

Security is an important aspect of Service-oriented Architectures (SOAs), enabling the service-based integration of partner IT systems across organizational boundaries, i. e., in the Internet of Services. Current trends in SOA security, e. g., reducing it to Web service security, do not take into account SOA-specific threats, vulnerabilities, and attacks. In this paper, measures to support the ...

Service-oriented development offers a novel architectural approach to business process development that addresses issues such as dynamic evolution and intraand inter-enterprise cooperation. Our emphasis in this paper is on the distribution aspects of that approach: we show how a ‘distribution logic’ can be defined that extends the typical ‘composition layer’ of service-oriented architectures wi...

Service-oriented architectures are rapidly gaining presence and popularity in the development of distributed software systems. Their rapid diffusion is changing the software engineering landscape and is opening the way to implement the idea of “software as a service” [19], i.e. something that one uses to compose a workflow that achieves a business goal, and then disengages. A service-oriented s...

For the last few years Sybase Company [SYB] proved its commitment to improving business modeling by creating integrated infrastructure for modeling enterprise businesses. Thanks to the incorporation of Service Oriented Architecture (SOA), Web services and business process execution languages, Sybase has significantly extended business modeling in almost every direction. This article is intended...

This literature review synthesizes existing research in the field of Service-Oriented Architectures (SOA) from a business perspective and integrates results from 40 works to offer researchers an overview about the existing body of knowledge in this research field as well as a research agenda, which unifies and extends previous efforts. While the literature regarding the technologies and design ...

BPEL4WS: Workflows and Service Components BPEL4WS [1] provides the most complete realization to date of the workflow execution model in the context of a service oriented architecture. Service oriented architectures introduce a set of very distinctive abstractions that result in significant modifications of the basic workflow model as outlined in pre-existing workflow model, see [2] for example....

This paper presents a service-oriented architecture that allows a more efficient distribution of resources and functionalities. The architecture has been used to develop a multi-agent system aimed at enhancing the assistance and healthcare for Alzheimer patients living in geriatric residences. Most of the system functionalities have been modelled as independent and distributed services, includi...
