Abstract

The concept of ranking and choice are closely related. The selection process is the final phase of the ranking procedure, the result of which is the preferred subset of alternatives. The ranking procedure is the process of establishing a strict order relation between a given number of alternatives. The PURPOSE of work is the experimental confirmation of the hypothesis advancing the idea that the problem of providing a strict order relation for complex ranking/selection problems can be overcome on the basis of mechanization (computerization) of the mental activity of the subject of choice via decomposition of original intuition manifestations on the set of presented alternatives into a set of particular, simpler problems. METHODS. The set purpose is achieved through the use of mathematical and statistical methods. RESULTS AND THEIR DISCUSSION. The procedure for establishing a strict order relations is presented by two aspects in two stages. In the first case, the number of alternatives is increased stage-by-stage under the fixed number of essential characteristics. In the second case, there is a step-by-step increase in the number of essential characteristics under the fixed number of alternatives. The process of establishing a strict order relationship involved the respondents with different choice strategies, who were offered to initiate the alternative ranking procedure first intuitively, and then by constructing a model of preferences in Decon Jobs software product. CONCLUSIONS. The specific examples of establishing the strict order relations between the alternatives obtained intuitively and using the averaged preference model allowed to conclude that the growth in the number of alternatives complicates a person to establish a strict order between them. The software product Decon Jobs allows to reduce the level of uncertainty between individual alternatives and to increase the percentage of establishing a strict order relation.
