The use of Internet as an ubiquitous communication platform puts a strong demand on service providers regarding the assurance of multiple service levels consistently. Designing flexible and simple service-oriented management strategies is crucial to support multiconstained applications conveniently and to obtain a deployable and sustainable service quality offer in multiservice IP networks. In ...

Service composition is an important means for integrating the individual web services to create new value added systems that can satisfy complex requirements. Such applications are subject to unexpected failure owing to the distributive and heterogeneous environment of web service. In this paper, we propose a Petri nets-based method to model and analyse the self-healing service composition. Asp...

This paper seeks to answer two questions: (1) Do consumers perceive the four service quality dimensions (reliability, responsiveness, assurance, and empathy) differently when interacting with Self-Service Technologies (SSTs) and human agents? and (2) How do these four dimensions affect consumers’ satisfaction when using SSTs versus using human agents? Based on an extensive literature review, we...

Suicide is a leading cause of deaths of U.S. service members. Medical care providers may play a role in suicide prevention. We summarized the outpatient experiences of service members prior to suicide or self-inflicted injury and compared them with service members without suicidal behavior. During 2001-2010, 45 percent of individuals who completed suicide and 75 percent of those who injured the...

Web services are widely used thanks to their features of universal interoperability between software assets, platform independent and loose-coupled. Web services composition is one of the most challenging topics in service computing area. In this paper, an approach based on High Level Petri-Net model as dynamic configuration schema of web services composition is proposed to achieve self adaptat...

The growing complexity of Web service platforms and their dynamically varying workloads make manually managing their performance a tough and time consuming task. Autonomic computing systems, that is, systems that are self-configuring and self-managing, have emerged as a promising approach to dealing with this increasing complexity. In this paper we propose an architecture of an autonomic Web se...

This paper presents a case study of implementing a user-centred approach in four software companies that, by supporting the development process, provide the municipalities with various self-service solutions for their citizens. This study outlines the process of how four companies develop their solution, including their customer involvement, end-user involvement, and product. The findings are c...

Quality of Service (QoS) is an often misunderstood term. The International Standardisation (ISO) efforts of the early 1990s on a QoS Framework showed that there are several QoS aspects, the most significant being performance, availability and security. Ultimately, the most important consideration is that the service provided (by whatever system is providing it) is for the benefit of the user. M...
