This paper presents a case-study of a Configuration Management (CM) tool evaluation. The evaluation was performed in a company with a long tradition of using CM tools. Although several generations of CM tools have been developed internally, different reasons led to a decision not to use CM tools internally developed but to buy a tool available on the market. A detailed evaluation was performed ...

As international competition continues to intensify, significant numbers of organisations are investing large amounts of resources into information and communication technologies as they seek to gain competitive advantage. Information Technology (IT) is increasingly being implemented for strategic reasons, so as to enable improved efficiency and to improve the control and productivity of intern...

This thesis presents a Web-based Virtual Learning Environment (VLE) called the Education through Virtual Experience (EVE) Portal which supports eScience learning for schoolchildren. The VLE guides students and teachers in the production of collaborative research papers to summarize their inquirybased activities. This thesis details the formative evaluations carried out on the VLE and provides e...

1 I n t r o d u c t i o n Systems which convert existing paper-based drawings into electronic format are in demand and a few have been developed. However, the performance of the prototypes and commercial systems is either unknown, or only reported in a limited way by the system developers. An evaluation for these systems, or their subsystems, would contribute to the advancement of the field. Re...

There is a need for modeling and performance evaluation techniques and tools for a fast and reliable design of workkow systems. This paper introduces a modeling methodology based on colored stochastic Petri nets. It allows the integration of functional, organizational, and timing aspects in one modeling framework. The processing delays include stochastic distributions in addition to determinist...
