Model of case-based reasoning decision-making support system

The process of decision-making support may rely on various approaches, namely: on various analytical models and on the analysis of situations using these analytical models; on statistical sources of data processing; on experience and intuition of experts who showed competence in the field; on case-based reasoning method. Each of the approaches might be important in a specific situation. But when a decision is hard to be made and there is no single opinion priorities have to be set. All of the approaches are widely used. This paper focuses on case-based reasoning method. Wholesale drug trade is very profitable and capacious part of Russian business.
