Ratings of Objects

Abstract

Rating points systems are widely used in various human activities (educational process, economics, techniques, etc.) and are of great importance in decision making problems [154-166]. These systems make it possible to get available and timely information in the form of an aggregative index and to use it in decision making problems. The complexity of obtaining rating points for objects with qualitative characteristics results from the general complexity of the quantitative assessment of qualitative characteristics. This complexity is also associated with the necessity of taking into account characteristics and judgements of the surveyors who take decisions based on their personal assessment. As a rule, the qualitative characteristics are scored in different scales and are often incomparable in principle. The elements of these scales (as a rule, order-type scales) are transformed into scores. Such transformation needs some substantiation because stability of the final findings depends on it.
