Finally, we perform a series of experiments employing several replication schemes and compare them with a non-redundant single service. Through the experiments, we evaluate both the reliability of the Web service paradigm and the correctness of the Web service composition algorithm. / In the paradigm, N-version programming technique is applied to increase the diversity of the system. As different versions of Web services or even different versions of their components are abundantly available in the Internet, the combination of different versions of the Web service or their components is thus becoming critical for enabling different versions in a server application using the N-version approach. We propose a dynamic Web service composition algorithm and evaluate with Petri-Net for verification purposes. / Moreover, we model the Web services with Markov chains and Petri-Nets to demonstrate the performance and reliability of the constructed Web services. Also, we develop the mathematical models to analyze the reliability of the Web services. / One of the latest achievements of the Internet usage is the availability of Web services technology and its dependability is becoming one of the most critical goals in Web related research. In this thesis, we propose a design paradigm for reliable Web services and a Web service composition algorithm. We describe the methods of dependability enhancement by redundancy in space and redundancy in time, using Round-robin scheduling technique, N-version programming and recovery block. The Web services are coordinated by a replication manager. It provides a Round-robin algorithm for scheduling the workload of the Web services and keeps updating the availability of each Web service. The replication algorithm and the detailed system configuration are described. / Chan, Pik Wah. / "March 2008." / Adviser: Micheal R.

The advent of the Internet and the World Wide Web has been instrumental in bringing about the growth in the implementation of web-based information systems (WBIS). Such systems are designed with the aim of improving productivity, data accuracy, and the reduction of paperwork and administrative overheads. Moreover, unlike their conventional non-web-based predecessors, the WBIS are commonly aimed at users who are casual and untrained, geographically distributed and non-homogenous. The dissemination of WBIS necessitates additional infrastructure support in the form of a security system, workflow and transaction management, and web administration. WBIS are commonly developed using an evolutionary approach, whereby the version of the application, acquired from the vendor, is first deployed as a pilot, in order to gather feedback from the target users before the evolutionary cycles commence. While a number of web development methodologies have been proposed by existing research, there is a dearth of empirical evidence that elucidates the experiences of project initiators in pursuing the evolution of web services, a process that undoubtedly involves dealing with stakeholder issues. This research project presents a phenomenological investigation of the experiences of project managers with the implementation of web-based employee service systems (ESS), a domain that has witnessed a sharp growth in Australia in recent times. However, the project managers’ rich, multidimensional account of their experiences with the implementation of ESS revealed the social obstacles and fragility of intra-organizational relationships that demanded a cautious and tactful approach. Thus, the study provides a socio-organizational perspective to web projects in contrast to the functionalist paradigm of current web development methodologies. The research also confirms that consideration of the concerns of stakeholders by project managers is crucial to the successive cycles of ESS evolution. Project managers address stakeholder concerns by pursuing actions that are aimed at encouraging ESS usage, but at the same time, such actions can have consequences necessitating subsequent iterations of system enhancement and improvement. Finally, the research also discovered that despite the different socio-political climate prevalent in various organizations, in which ESS are being implemented, the experiences of project managers in dealing with stakeholder concerns can be captured and independently confirmed in terms of their perceived relevance and usefulness in problem-solving within the application domain.
