New approaches to dynamic evaluation of quality indicators

Abstract

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.

Application of modern information technologies in the technological processes organizing system of a construction expert

“…The activities of a construction expert can be considered as a set of targeted activities, related to one degree or another to the creation and processing of information relating to various aspects of the existence of a construction project at all stages of its life cycle. Effective work with significant amounts of information is possible only in an automated mode, with the active use of appropriate computing power and data storage [21,22]. Thus, the best solution in optimizing the work of a construction expert is the use of computeraided design systems that implement information modeling technology, which allow:…”

Digital Technologies and Elaboration of Mechanisms for Expert Examination of Scientific and Technical Potential of Universities

“…Expert examination mechanisms are an integral part of all mechanisms in generating scientific and technical potential of universities. Works devoted to studying the expert examination mechanisms [1][2][3] note that it is necessary to take into account the fact that the experts themselves are either interested in the results of the expert examination, or in increasing their own ratings, which depends, on how often during the expert examination their assessment coincides with the resulting assessment by all the experts. Let us show, how to take into account this kind of interest ensuring correctness of expert assessments in modern university projects and programs.…”

“…Let us consider without losing generality, as in [1][2][3], that experts are arranged in the descending order of their true estimates:…”

“…Moreover, u+v=n. Works [1][2][3] determine for experts interested in increasing their rating target functions that reflect the expert's interest in obtaining the resulting expert assessment, as close as possible to the one reported by such an expert. Based on this and taking into account (4) the target function of experts included in a team conducting the expert examination, the following could be written down:…”

Methodical approaches to destructive and non-destructive testing application in forensic construction and technical expertise

“…Control is important at all stages of the life cycle of buildings and structures [2]. When inspecting a building in the process of construction and technical expertise, there are two main ways to control the quality of building materials, products and structures: destructive and non-destructive [3]. The main task of control is to ensure safety during the facility operation [4].…”
