USE OF ONTOLOGICAL NETWORKS IN DECISION SUPPORT SYSTEMS UNDER AMBIGUITY

relevance of building intelligent decision support systems. The prerequisite for making the right decision is to build a correct conceptual model of the problem situation, which takes into account all the factors relevant to this situation.
