The utility problem occurs when the performance of learning systems degrade instead of improve when additional knowledge is added. In lazy learners this degradation is seen as the increasing time it takes to search through this additional knowledge, which for a sufficiently large case base will eventually outweigh any gains from having added the knowledge. The two primary approaches to handling...

In this paper, we discuss the usability of an antibiotics therapy adviser, with a broad, complex spectrum of functions which we have developed within the ICONS project. We present the architecture of the system, case-based reasoning methods used, steps and results of medical evaluations, which are concerning the quality of the recommended therapies, the user friendliness of the system and the i...

The purpose of this paper is to present the performance evaluation of computer system with failure based on fuzzy set theory. The performance evaluation of on-line computer system with failure is fuzzified. We represent the performance measures of the on-line computer system by modeling occurrences of failed computer equipment units based on fuzzy set theory. We are forced to employ subjective ...

The article presents the main results of a joint investigation by Swedish researchers and industry representatives carried out during 2006-2007 concerning the benefits of modern object based information and communication technology, ICT, for industrialisation of the building industry. The background for the investigation was an experience by both parties of a lack of coherence between scientifi...

Rapidly evolving information technology has dramatically changed the knowledge dissemination process. A proper e-learning environment is one of the most important knowledge tools in modern organizations. However, many of them lack a generic evaluation process to verify performance. In an attempt to solve this problem, this study propose an agent-based model which compose learning model, balance...

The condition that varieties of cities including Iranian cities are confronted makes the creation of successful public space a necessity. It is clear that for creating suitable public space first we should understand the influencing factors on space and simultaneously solve and improve the problems through understanding the environment. For achieving the factors that influence the success as a ...

considering the major change occurred in business cells from plant to “chain” and the critical need to choose the best partners to form the supply chain for competing in today’s business setting, one of the vital decisions made at the early steps of constructing a business is supplier selection. given the fact that the early decisions are inherently strategic and therefore hard and costly to ch...

The performance evaluation of the regional innovation system (RIS) based on the management entropy theory can dynamically describe its overall innovation level and its development trend. This article describes the content of management entropy theory and analyzes its function mechanism of the RIS. On the basis of above, this article establishes its own index evaluation system and entropy evalua...
