Discussions on Applied Mathematics in Decision-Making Modeling with Decision Support Systems and Knowledge Based Systems

This paper tries to discuss some findings in mathematical decision-making modeling models with applications in business processes. We start by presenting some technological implications and implementations of decision-making models. After this we discuss some implementations realized by us and that consists in a neural network, a JAVA implementation of the decision-making model, an expert systems-shell implementation and an implementation with ontology and inference engine. The paper ends with usefull conclusions drawn for decisionmaking modeling activities. Key-Words: decision-making, DSS, KBS, ontology, inference engine, OWL
