Decision support system for choosing a study program

The article explores an approach that enables a reasonable choice of a study program in an educational organization. Existing information tools used by educational institutions to support applicants are typically based on admission rules, study areas, and historical data on the average grades of previously admitted students. This paper proposes incorporating Holland test results into the decision-making process for choosing a study program and integrating this data into the decision support system's selection rules.The decision on the most suitable study program for the user is made progressively, considering the degree of confidence in its accuracy. This approach provides structured guidance to the user by: orienting them on the rules for admission to an educational organization; determining the priority study area based on broader groups of specialties and fields; identifying the most appropriate program within the chosen study field. The novelty of this approach lies in mapping the six primary psychological types identified by the Holland method to the study areas of an educational institution. Based on this comparison, a knowledge base is developed in the form of decision-making rules. The possible choices are evaluated using linguistic variables that reflect the user's confidence level in the recommendation provided by the information system. To enhance the accuracy of the decision support system, the decision-making process model is refined when forming decision-making rules.
