A framework for customizing public services (2011)

Haque, Rafiqul; Richardson, Ita; Whelan, Eoin; Taher, Yehia; Van den Heuvel, Willem-Jan; Tawbi, Samar

Abstract:

Processes are the main constituents of public services and as such demand correct and complete execution. Increasingly however, governments feel the pressuring need to deliver public services more quickly and personalized to the needs of local communities or citizens. This not only jeopardizes their quality but also requires them to form teams that combine deep technical and programming knowledge with business experts. It is the aim of this research project to deliver a framework that allows non IT-experts to customize prefabricated and generic processes by parameterizing them. This customization revolves around reference guidelines that accommodate multiple-viewpoints in a consistent manner.

A multi-layer approach for customizing business services (2011)

Abstract:

The reusability of services is a cornerstone of the Service-Oriented Architecture design paradigm as it leads to a reduction in the costs associated with software development, integration and maintenance. However, reusability is difficult to achieve in practice as services are either too generic or over-specified for the tasks they are required to complete. This paper presents our work in defining an approach for achieving service reusability in Service-Based Applications (SBAs) by decomposing the reusability requirements into two layers and then into separate views that allow the customization of business policies, quality of service, tasks and control (i.e., orchestration/choreography) parameters. The objective of defining such an approach is to provide an appropriate solution that will guide the customization of a service’s functional and non-functional properties to allow it to be reused in different business contexts.

Designing and delivering public services on the cloud (2011)

Designing and delivering public services on the cloud (2011)

Taher, Yehia; Haque, Rafiqul; Nquyen, Dinh Khou; Van den Heuvel, Willem-Jan

Abstract:

Cost and complexity are currently the most substantial obstacles for designing and delivering services in the public sector. The traditional in-house development and maintenance landscape of public services require experts from diverse domains, various technologies and complex on-premise infrastructure, etc. The high upfront cost and complexity impede the proliferation of Information Technology (IT) within the domain of public sector. It is the aim of this research project to deliver a cloud based platform that allows non IT-experts to customize prefabricated and reusable public services by parameterizing them. This customization revolves around reference guidelines that accommodate a methodology in a consistent manner.

PAEAN- a risk-mitigation framework for business transaction at run-time (2012)

PAEAN- a risk-mitigation framework for business transaction at run-time (2012)

Cfarku, Denada; Taher, Yehia; Haque, Rafiqul; Van den Heuvel, Willem-Jan; Papazoglou, Michael P

Abstract:

The increasing complexity of the business transaction results in a higher potential risk in terms of SLA violation. The fulfillment of the QoS constraints specified in global SLA can be threatened at any time by different unexpected events that could occur during the execution of a business transaction. Unfortunately, there is no solution found that can efficiently mitigate this risk. Some of the current business transaction monitoring and managing solutions can monitor business transaction and report fault only after it happens. The framework proposed in this paper, monitors business transactions, computes potential risks and performs proactively adaptation actions in order to avoid global SLA violation that could causes transaction abortion.

Towards a framework for customizing the views of reusable public service processes (2011)

Haque, Rafiqul; Taher, Yehia; Richardson, Ita; Whelan, Eoin; Van den Heuvel, Willem-Jan; Tawbi, Samar

Abstract:

Processes are the primary constituents of public services and as such demand the completeness to achieve the goal of services. Ensuring the completeness of processes is a challenging task because, in recent days, they entail multiple views stemming from distinctive fields. It requires forming teams that combine deep technical and programming knowledge with business experts. These teams of experts are enormously expensive. Besides, increasingly, the public service organizations realize the need to deliver public services more quickly and personalized to the requirements of local communities or citizens. The service organizations may achieve rapid delivery of services either by hiring a team of experts or by using a solution that underpins the local (human) resources that are non IT-experts to customize the reusable processes that encapsulate services. The former is not an ideal option for many public service organizations owing to the cost. In case of latter, unfortunately, there is ...
