Abstract
The paper analyzes the existing methods for getting a numerical indicator of the quality of a technical product in the modern industry at the product design stage. The objective is currently relevant as the quantitative assessment of the quality provides comprehensive information about the object in terms of its suitability and feasibility of use for solving any technological problems and production management, and makes it possible to develop a technically complex product with the predetermined characteristics and quality. When solving problems dedicated to assessing the quality of automotive vehicles and tractors, we propose a reasonable application of the concept of mobility as an integral operational property of transport and technological machines. A variety of approaches to getting quality assessments include integral indicators, showing the greatest popularity and confirmed reliability, calculated by multi-criteria optimization methods assuming the decomposition of the integral property into the simplest components and then the aggregation of empirical indicators factoring into their weight by the additive convolution. The authors analyzed various methods of finding weighting coefficients, and indicated feasibility of their use. The study has showed that the existing approaches are devoted to assessing the quality or mobility of individual technical products and classes of automotive vehicles and tractors. Though there are no currently available impartial, universal and practical methods used to calculate the quality indicator of any transport and technological machine (TTM). The paper provides the prerequisites, contributing to the development of a universal algorithm for calculating the integral mobility index, which can form the basis of a product quality management system at the stage of designing automotive vehicles and tractors.
