This paper demonstrates that case-based reasoning is ideally suited to the creation of knowledge management systems. This is because of the close match between the activities of the CBR-cycle and the requirements of a knowledge management system. The nature of knowledge within an organisation is briefly discussed and the paper illustrates the dynamic relationship between data, information and k...

The explosive interest in Knowledge Management and systems to support this as an organizational endeavour, require closer scrutiny than might be normal from the I/S function. Empirical research indicates that knowledge based systems might be better considered as ‘peoplecentric’, rather than from a technology platform perspective.

This paper extends the RBAC model to deal with permission in a workflow management system. The extended model allows for dynamic constraints on instances of processes. We also extend the model so that delegations from an user to another user, and revocations of such delegations are dealt with. We also discuss the issues on delegations from a user to a group of users.

Deliberate exploitation of natural resources and excessive use of environmentally abhorrent materials have resulted in environmental disruptions threatening the life support systems. A human centric approach of development has already damaged nature to a large extent. This has attracted the attention of environmental specialists and policy makers. It has also led to discussions at various natio...

In this paper, we investigate the modern issues of knowledge management and their impact on our living environment including business practices and health issues. We describe our vision through a highly computerised framework that combines technologies from different disciplines such as knowledge-based systems, database systems and multimedia technologies to support various knowledge management...

This paper focuses on the project case, which is based on the project time management theory, combined with the software project, especially the characteristics of the software project based on cloud computing platform. We show the general process of software project progress management. For different processes, we propose schedule arrangement for better management. Through the project activity...

Frameworks for IT evaluation have been extensively discussed in the past. Until recently, research had concentrated on advancing classic approaches such as monetary cost/benefit considerations or strategic management matrices, but that constriction to known methods has considerably softened. More researchers now use economic models in IT evaluation. Their contributions open exciting new perspec...

This paper addresses the issue of improving the performance of memory management for real-time Java applications, building upon the Real-Time Specification for Java (RTSJ) from the Real-Time Java Expert Group. In a first step, a thorough analysis of the parameters influencing the performance of memory management together with ways of improvement are presented. The implementation of a memory man...
