New approaches to dynamic evaluation of quality indicators

摘要

The paper proposes a mathematical model for evaluating time-varying quality indicators of an arbitrary nature. The model is based on the Rasch's method of estimating latent variables. Cases of single-criterion and multi-criteria evaluation are considered. The obtained estimates are measured on a linear interval scale and do not depend on a set of indicators, time periods and evaluation criteria. Comparison of results with traditional assessment methods.
