Systematic forecasting of product quality of spinning production

Abstract

Forecasting product properties and mana­ging its quality consists in ensuring and main­taining the required level of product quality starting from its development, production and operation or consumption. These measures are carried out through systematic control and specific action on the conditions and factors that affect product quality, to forecast its properties and manufacture products with specified properties. Forecasting tasks are directly related to the availability of adequate mathematical models of product properties change during its production process. The hypothesis of this work is that a systems approach is the basis for creating a modern approach to obtaining a mathematical model for predicting the properties and quality of fiber products. The article defines approaches to forecasting the properties of textile threads and products during production by applying system analysis and mathematical modeling. A general process algorithm and a structural and functional model of the elementary cell of the production process of transforming product properties are proposed. To determine the state of the technological system for the production of textile threads and products, methods of system analysis and mathematical modeling of product properties during its production process are used. Modeling of product quality manage­ment and forecasting systems includes a description of the sequence of processes and operations that form the properties of finished products and semi-finished products, and are aimed at ensuring, maintaining and improving product quality. Using a mathematical model, quantitative relationships between the quality indicators of finished products and the properties of derived raw materials, semi-finished products, technological equipment and management actions by the relevant authorities are determined. The use of mathematical models for predicting product properties and managing its quality allows you to pre-determine and evaluate the results of certain measures and select those of them that are most effective for implementa­tion. The basis of a mathematical model for predicting the properties and quality manage­ment of textile products can be a model of the production transformation of derived materials into finished products.
