The existing model of Federated Identity Management (FIM) allows a user to provide attributes only from a single Identity Provider (IdP) per service session. However, this does not cater to the fact that the user attributes are scattered and stored across multiple IdPs. An attribute aggregation mechanism would allow a user to aggregate attributes from multiple providers and pass them to a Servi...

In the face of competitive pricing pressure from online retailers and high-quality service physical retailers, are in these two channels willing to establish a cooperation (SC) strategy? If so, then will they support or avoid consumer showrooming behavior? To address questions, we use game theoretic model examine three strategic configurations: nonservice (SN), SC, nonshowroom (NC). We recommen...

Customer satisfaction analyses are deeply based on customers’ judgments and as consequence, they can be characterized by a certain degree of uncertainty generally ascribed to coexistence of three relevant aspects: vagueness, imprecision and subjectivity. In the present paper, a methodology able to handle such uncertainty, based on the ServQual discrepancy paradigm and that uses in combined mann...

Maintenance support service network (MSSN) is used to provide maintenance services and maintain the operational status of equipment. However, performance MSSN has been significantly influenced by inevitable disturbance, which makes it vital its robustness. Existing research on robustness mainly focuses single-layer rather than two-layer network, imposes constraints disturbances limits applicati...

Condominium management (CM) businesses rely on continuous improvements to service quality (SQ) to increase consumer satisfaction (CS) and thereby improve operations. Lacking knowledge of SQ and CS results in poor efficiency. To develop cost-effective strategies for improvements, the relationship between SQ and CSmust be investigated. This work proposes novel procedures to explore the relationsh...

One purpose of this study is to explore theoretical background to find out store image attributes suggested by many previous researchers as important determinants of store loyalty and another is to identify which store image attributes affect store loyalty significantly according to retail type respectively. The results of empirical analyses show that store image attributes of store loyalty dep...

In the past twenty years, the multi-agent technology has been widely employed for developing agent-based systems. Currently, agent-based service-oriented applications have been widely applied in many complex domains such as e-markets, grid computing, e-governments and service-oriented software systems, across Internet and organizations. In this kind of service-oriented multi-agent systems, serv...

This paper presents an analysis of security aspect of Web-Based applications that utilize Service Oriented Architecture (SOA). The architectural solutions which address security requirements are examined and compared with other quality attributes relevant to web-based systems. More specifically, a trade off analysis in which security is the main focus is performed to select an architecture that...
