Applications of Decision Support System in Aviation Maintenance

The basic purpose of aviation maintenance is to prevent the decreased levels of original aircraft airworthiness, safety and reliability design at the lowest cost, which is of great significance to the running of air transport enterprises. According to statistics, aviation maintenance accounts for approximately 20% to 30% of direct operating costs, not including indirect costs caused due to maintenance, such as flight delays, material and spare parts, corporate image. In recent years, as the rapid development of civil aviation industry, a large number of new technologies have been used in airplanes, which increase the complexity of the civil aviation maintenance, especially the application of digital information technology. In response to modern aviation maintenance of the new situation, so as to adapt to the future development trend of digital maintenance and improve the efficiency and quality of modern aircraft maintenance, establishing the necessary modern air transport aircraft maintenance decision support system becomes increasingly urgent. For this reason, this paper in-depth analysis the problem of how to build the aviation Maintenance Decision Support System (MDSS).
