Keywords: qualimetry, production and technological system production, products, quality, efficiency.

Abstract

Some issues of qualimetry in production and technological systems are revealed. The scheme of researches concerning estimation, forecasting and quality control of products from a metalwork and their production and technological systems is resulted. The most significant procedures for solving qualimetry problems are identified. A strategy for comprehensive assessment of the quality of equipment and production and technological systems is proposed. It is emphasized that to assess the quality of production and technological systems of manufacturing products developed a methodology based on the definition of a dynamic comprehensive quality indicator. Each of the individual indicators of quality of production and technological system is substantiated, the list of which includes the indicator of continuity, specialization, implementation of plans, automation of production and technological system, production defects, progressiveness and technical and economic efficiency. The method of calculation of each of the listed unit indicators of quality of production and technological system is considered. It is emphasized that in order to determine a dynamic complex indicator of the quality of the production process, in addition to the calculation of individual indicators of the quality of the production process, the weighting factors of each indicator must be determined. Weights can be determined by various methods, for example, the method of parametric and cost regression, the method of limit and nominal values, the method of equivalent ratios, the expert method. It is noted that the accuracy of expert assessments is determined by the consistency of expert opinions, and the degree of coincidence of expert assessments is expressed by the concordance coefficient. It is noted that in the approach to qualimetry the main part is selected, which determines the quality of quantitative expression of the production and technological system. It is substantiated that the selected basic part is accepted by the expert as a standard of quantitative analysis of other parts in the field of research. Next, the parameters are calculated, which are called the quality parameters of the production and technological system.
