The results of artificial intelligence research are playing an increasingly important role in decision support and economic modelling computer systems, so are software agents whose application is present in almost any field of information technology. The agent is an autonomous "subsystem" which monitors its environment through its sensors and makes changes to it with its intervening organs, it is capable of adapting to its environment, and by using this knowledge it is able to make alteration to its plans or actions to improve them. The application of agents may lead to resounding results in economic modelling as well. The study outlines the characteristics of decision making which are important as regards the assessment of agents as well as the major features of software agents and their possible economic applications.
