Investigation of Decision-Making Process by the Use of Knowledge-based System

Each problem always originates from constraints. The decision is a response to the challenges by the environment. In order to chose appropriate decision support techniques the structural complexity of the problem has to be determined. The aim of the application of knowledge based systems is to obtain decision support. In this paper the application of the system ‘Doctus’ is illustrated and exemplified in connection with processing an actual problem. The question is whether rather the ‘yes-no’ decisions representing the classical binary logic or the fuzzy logical way of thinking will be realized. The analysis was carried out by the application of inductive and deductive inference procedures taking into account the considerations which are influencing principally the decisions. The assessment of the results obtained may generate further dilemmas for the solution of which appropriate knowledge bases can be brought about or the already existing ones have to be refined.
