Improve the integrity testing process based on QFD, FMEA and TRIZ

Abstract

In today’s aircraft industry – competitiveness in the domestic and foreign markets, is the main criterion for the development of quality, a high level of which is achieved through methods and approaches: QFD, FMEA, TRIZ. There is a possibility of application of these methods at tests of production, for the purpose to meet expectations of consumers with the most optimum combination of characteristics of production.The design process is often associated with a compromise of conflicting parameters, which means increased costs and loss of quality. Innovation in the production process can create great value. The rapid development of modern technologies and the commercial environment suggests that the design of production processes requires the application of a systematic method of improvement. The proposed method combines a number of quality tools to support the process of modern development of aviation. In order to implement the acceptance improvement, it is necessary, first, to analyze the product testing process in accordance with the influencing parameters and use QFD (quality function deployment) to obtain the basic requirements for the testing process. Secondly, to find the contradictions of the testing process and analyze them comprehensively. To creatively solve the revealed contradictions, apply the Russian theory of inventive problem solving (TRIZ). When using this technique increases both the efficiency and maneuverability of the use of quality tools to solve technological problems. The effectiveness of the proposed method of improvement is illustrated and confirmed by the example of the process of testing the tightness of the hose of the life support system of the product “Bion - M”.
