Abstract

Human factor is more and more important in new information systems and it should be also taken into consideration when developing new systems. Trust issues, which are tightly tied to human factor, are becoming an important topic in computer science. In this work we research trust in IT systems and present computer-based trust management solutions. After a review of qualitative and quantitative methods for trust management, a precise description of a simulation tool for trust management analyses is given that was implemented on purpose for this work. The main part of the work is an analysis of simulations, which were run with different initial parameters. With analysis of obtained results we show whether initial parameters have influence on agents behavior, what is typical behavior of single agent in a community and what are possibilities for trust management in information systems.
