INTRODUCTION

Statement of the Problem or Task in General Terms

Successful competition of Russia with other countries is not possible without a significant improvement in the quality of domestic products. The task of improving quality can be achieved only if all spheres of production and economic activity of enterprises are involved in its solution; and if the company's specialists have the relevant knowledge in the field of quality management. Initially, a strong impulse to acquire knowledge in the field of quality, as well as to create quality management systems at enterprises, was given to domestic enterprises in 1987 by international ISO 9000 series standards, which describe the quality management models for enterprises of any field of activity (Khorasani & Almasifard, 2017). In parallel, the availability of quality systems was required by both customers/consumers and government bodies, which required a guarantee of obtaining high-quality, safe products. The interest in creating quality systems at the manufacturer is also explained by the emerging opportunities to improve production, increase the efficiency of its activities and enter new markets (Kuznetsova, 2017). It is becoming the norm to have certified examination of quality system at the enterprise. Thus, the relevance of the study is due to both external factors associated with the change in the competitive situation in the markets, the requirements of consumers and internal ones, the necessity to meet all the requirements of the international ISO 9000 standard.

METHODOLOGICAL FRAMEWORK

The following specialists (who published their works in different years) are considered to be classics in the field of quality: (Saxon, 2001; Watson, 2005; Juran, 2014; Shewhart, 1939; Taguchi, 1976; Deming, 1993; Ishikawa, 1988; Juran, 1995). ISO specialists who developed the standards of the 9000 series tried to take into account the authors' positions, both in the interpretation of categories and the essence of the quality management system.

The definition of the concept of product quality can be proposed in the following form: product quality is a set of essential properties quantitatively evaluated by the system of technical and economic indicators that distinguish products from another similar purpose that determine the demand for products in market conditions at socially necessary costs and market prices for this production (Kuznetsova, 2015). The purpose of this study is to determine the level of effectiveness of the quality management system at the enterprise on the example of the Volkswagen/Skoda project in the welding department of OJSC "GAZ", as well as to develop measures for its improvement and enhancement. On the basis of the goal set, the tasks for its implementation are as follow:

  1. To assess the effectiveness of the processes of the quality management system of the research object;

  2. To propose ways to increase production efficiency on the basis of the principle of end-to-end integrated quality management and the requirements of international ISO series standards of TS16949.

    RESULTS AND DISCUSSIONS

    The study deals with the improvement of the QMS of the enterprise of OJSC GAZ Group on the Volkswagen/Skoda project, the welding department. The department produces welded bodies of Skoda Octavia A7, Skoda Yeti face lift and Volkswagen Jetta assembled with hang-on parts. The Volkswagen/Skoda project operates with a quality management system developed in accordance with the requirements of GOST R ISO 9001. The structural diagram of the Volkswagen/Skoda quality system in the welding department is created on the basis of the structural diagram of the enterprise and gives an opportunity to show the composition and interrelation of all structural units performing functions in the quality system. The quality of the products produced by the welding department is subject to high demands both on the quality of the surface, on the quality of the welded joints and on the vital connections of the vehicle. Quality assurance of the output of the welding department is carried out in stages (Garina, Kuznetsov, Viktor, Lapaev, Dmitry, Romanoskaya, Elena, Yashin & Sergey, 2017):

    Determination of QRK Control Points (Qualitats Regel Kreis)

    In the body welding department, quality control (the QRK points) in the production process was introduced. Welding controllers work at the control points of welding. Work on control points is carried out according to the documentation. There are 2 control points QRK in the welding department at the moment: QRK1-floor quality control station 2060 and QRK2quality control of the base station 6400. At the QRK quality control station 1st. 2060, the underbody is inspected for defects, tracing so-called "TOP" defects, the correction of which is guaranteed. Also, the defect statistics form is maintained. Operators conduct feedback with the leaders and masters of the site concerning the emergence of mass defectiveness. Correction and prompt feedback by operators at the QRK station of detected defects on site allows improving the quality of products (Schiffauerova & Thomson, 2006). At the QRK quality control station 2st. 6400, the bodies are inspected for defects, tracing TOP defects, the correction of which is guaranteed. Also, the defect statistics form is being maintained. Operators conduct feedback with the leaders and masters of the site concerning the emergence of mass defectiveness. Correction and prompt feedback by operators at the QRK station of detected...
