In general, Policy-based approaches play an important role in the management of web services, for instance, in the choice of semantic web service and quality of services (QoS) in particular. The present research work illustrates a procedure for the web service selection among functionality similar web services based on WS-Policy semantic matching. In this study, the procedure of WS-Policy publi...

Software as a Service (SaaS) has been developing for over ten years and, is reaching a mature level, where quality and its monitoring and management become significant. Although, SaaS is derived from the ASP model, SaaS background and architecture is different and therefore also SaaS quality management is based on different concepts. This paper is focused on the difference between traditional I...

Grid computing is generally viewed as task assignment to distributed resources. While in practice many factors do complicate this scheduling process (e.g. resource monitoring and discovery, resource failures, resources ownership and policies ... etc), the process is still viewed as resource scheduling according to some criteria. The criteria are referred to as Quality of Service (QoS) attribute...

This paper attempts to compare the classification of quality attributes using Kano’s method and the service gaps method proposed by Kong and Muthusamy (2011). Expectation and perception data from 80 articles were systematically reviewed. Only two articles with classification of quality attributes by Kano’s method were identified. Four service quality factors were apparent from this study, and e...

In this work the Service abstraction is extended to support Quality of Service (QoS) attributes – and implemented in the Grid QoS Management (G-QoSM) framework. The framework supports three main functions: (1) providing mechanisms for establishing QoS guarantees via Service Level Agreements (SLAs), (2) enabling QoS management on allocated QoS-aware services, and (3) supporting discovery of serv...

In Grid service environments, traditional identity based access control models are not effective, and access decisions need to be made based on service requesters’ attributes. All of previous attribute based access control (ABAC) models are lacking in protection of users’ privacy because in these models, access control decisions are made by providing the service provider with user attributes. T...

Background: Nonmarket stated preferences valuation, especially discrete choice experiments (DCEs), is one of the commonly used techniques in the health sector. The primary purpose of this approach is to help select attributes and attributes-levels that are able to properly describe health care products or services. This study aimed at developing attributes and attributes-levels for basic health...

Based on SERVAUALmodel, this paper brings in the entropy method to rank quality improvement (QI) priority for service attributes, and a service quality evaluation(SQE) model integrating competitive analyses has been structured to evaluate the mobile communication service quality (SQ) for Wuhan Branch of China Telecom(WBCT). The research shows that the QI priority of 22 service attributes has ch...

Quality-of-Service (QoS) in Web services considers a service’s nonfunctional characteristics during service specification, discovery, and composition. In order to encourage the development of QoS-aware Web services, we first develop a QoS-aware model, which contains a common set of QoS attributes including response time, throughput, reliability, availability and price etc. Then, based on the at...
