[Abstract]:Efficient fuel utilization is of great significance to the construction of "resource-saving" and "environment-friendly" society in our country, which is in the field of civil aviation. Improving the efficiency of fuel utilization is also one of the important objectives of each airline in the aircraft operation management, but because of the complexity of the route operation, the characteristics of diversification. The evaluation of aircraft fuel efficiency of airlines is difficult to be measured by a single or several indicators of monitoring aircraft. It is necessary to configure multi-point data monitoring for the flight transportation process, which makes the monitoring data very complex. Based on a large number of airline fleet operation data, this paper focuses on the determination of monitoring indicators and the design of fuel consumption performance model from the methods of aircraft fuel consumption monitoring and evaluation system. Base line and boundary line design, the establishment of a reasonable monitoring method system for the aviation fleet of China's fuel consumption monitoring method, and to explore the construction of methodology. Analysis of the background and significance of the subject, proposed that in the era of rapid expansion of data resources, airlines need to make full use of flight data to carry out various aspects of research. Among them, the analysis of fuel consumption data is an important link. The application and research of domestic and foreign aviation enterprises in fuel consumption monitoring methods and their evaluation methods are summarized, and the characteristics of fuel consumption monitoring systems of some airlines are analyzed. And the aviation fuel consumption and its influencing factors are introduced theoretically. Secondly, a set of aircraft fuel consumption monitoring method theory based on scale data is proposed to refine the analysis process and build a demand analysis framework. Using the CDM methodology for the construction of oil consumption monitoring methodology, selected several types of indicators through the principle of index selection to construct an exponential attenuation performance model based on flight distance. This kind of model can classify different fuel consumption models and define the parameters of performance and distance. Combined with the fuel consumption evaluation index method to analyze the applicability of all kinds of models, select a suitable fuel consumption evaluation monitoring method. Thirdly, determine the fuel consumption performance model monitoring evaluation index baseline and boundary line method. Using artificial neural networks. The theory of signal separation and three methods of least squares are used to determine the standard. This paper mainly introduces the RELAX algorithm of signal separation based on the established fuel consumption model and a cross-iterative optimization of the generalized inner product synthesis of non-consistency detection. The method of computing. This method can estimate the datum effectively under the strong "noise", and reasonably determine the input and output data of the fuel consumption model. Finally, by comparing the advantages and disadvantages of the three methods, the optimal selection of different fuel consumption models is put forward. Method to verify the correctness. Finally, three methods were used to verify the fuel consumption performance evaluation model based on distance and the single factor model was constructed. According to the data of 550 flights of a certain airline flight B737. The data of 8430 flights with the A330 were classified and modeled. This paper analyzes the noise performance and fitting performance of the algorithm, and combines the advantages and disadvantages of the three methods to estimate the overall model and the classification model. It provides an effective method for the study of fuel consumption monitoring methods of airlines. Through single factor analysis and data contrast, the oil consumption monitoring method system is perfected and verified. The advantages and disadvantages of various methods are summarized. Put forward the summary and prospect of the work.
