CALCULATION OF REAL ESTATE RATING BASED ON STANDARDS AND USER PREFERENCES

The paper discusses issues of comprehensive assessment of real estate objects consumer properties. Such an assessment is intended to serve as a basis for ranking the market offer for different types of objects. The presented research phase focuses on residential real estate and in particular apartments in apartment buildings. A review and analysis of existing approaches to assessing the quality and comfort of housing is provided. Two main groups of parameters characterizing the internal and local components of the assessment are identified. Analysis of open sources of information about the proposal of apartments conducted using the developed software solutions. On the basis of this analysis, a list of criteria for their evaluation has been formed, variants of values and three types of rating scales have been determined. The degree of importance of each criterion for the final apartment quality indicator is calculated using the method of pairwise comparisons. To account for the influence of negative parameters on the final rating, the mechanism of penalty coefficients was chosen. An own method for rating apartments has been proposed, taking into account both regulatory requirements for ensuring quality of life and user preferences. Testing of the developed method was carried out using the created prototype of the program on five sets of user preferences, demonstrating a change in the indicator of comparative importance in the matrix of pairwise comparisons according to the real estate quality criteria typical for these groups.
