Modern computer based systems usually confront their users with an enormous complexity. This statement applies in particular to real time or near real time applications as, for example, vehicle and process control or command, control, communication, and intelligence C3I. While in former times there often was too little information for reasonable decision making, today in general there is too much. Hence, important detail may be overlooked in an avalanche of irrelevant detail. There is also concern with respect to the respect to the reliability of computers in such systems. As a consequence, efforts are undertaken to support the human user of highly automated systems by providing so-called decision support systems DSS. If we follow the definition proposed by Zachary, a DSS is any interactive system that is specifically designed to improve the decision making of its user by extending the users cognitive decision making abilities. In order for a DSS to be useful, users must be able to integrate the computer aid into their own cognitive processes.
