Thus, in the labor market there are vacancies with their parameters and applicants – with their own. There is a choice in the process of which the parameters of vacancies and applicants are compared (Fig. 2.1).

V_i{a, b, c, d, e} is compared with S_i{a, b, c, d, e, f}, or with P_i{a, b, c, d, e, f}, or with B_i{a, b, c, d, e, f}.

In the presence of coordination of parameters and wishes the vacancy is liquidated, the applicant receives the workplace.

Let’s analyze the component 1. Employers form vacancies and describe them in the form V_i{a, b, c, d, e}. The following sites were used to analyze the set of vacancies by specialties and educational programs: rabota.ua, work.ua, jobs.ua.

Parameter «c» from the vacancy formula V_i{a, b, c, d, e}.

For 2017, 2018, 2021, 396,955 vacancies were offered in the ads. During this period, the list of specialties and educational programs for which specialists are trained at the university has changed somewhat. The specialty «Entrepreneurship, Trade and Exchange Activities» was added, which included, among other things, the educational program «Real Estate Management». Not only the list of specialties (groups of specialties) has changed, but also their popularity among employers (Table 2.1). Column 2 of this table lists specialties, educational programs and their groups. This combination is due to the similarity of professional competencies, which are listed in the ads according to the vacancies. Employers, as a rule, do not use the official list of specialties, because they are not interested in the names of specialties, but the list of competencies of job applicants.

Therefore, for the convenience of teaching the material in the future we will call specialties, educational programs and their groups, which are presented in Table 2.1 by the term «specialty».

In the first place in 2021 the specialty «Entrepreneurship, trade and exchange activity» was fixed. Employers offered 14,321 vacancies in this specialty, which is 21.3 % of the total.
