The Decision Support System Education Career Choice Using Fuzzy Model

The decision support system has been developed to select the direction of study for applicants. It is based on a two-level mathematical model, which includes, at the first level, an expert system, and at the second level, a fuzzy inference model to describe the selection process, which are complex and non-linear. The developed expert system gives an idea of the area of knowledge to which the future specialty can be attributed. The fuzzy model allows you to determine a specific specialty for future education. To assess the influence of the input parameters on the output variable of the choice of the direction of training, five fuzzy choice models are used, which are built on the input linguistic variables. Their terms, membership functions, and intervals of the universe are given. A knowledge base for each model has been developed, consisting of production rules, which are presented in the form of fuzzy linguistic statements. Experimental studies have been carried out, which confirm the effectiveness of the developed models. The ability to be tested using the system and get results in the form of the name of the specialty will improve the informed choice.
