Application And Research On Data Mining On Aero Maintenance

With the aviation maintenance process of information creation and acceleration, a growing number of aircraft maintenance units using computer records of daily affairs aviation maintenance data. After accumulating, aviation maintenance data on more and more. Aviation Maintenance and Aviation Maintenance data is actually a collection of information related to the activities, when the amount of data accumulated to a certain extent, necessarily reflect regularities.In this paper, the urgent needs of the field of Aviation Maintenance, the application of data mining theory, methods and techniques designed aviation maintenance data mining system architecture framework; based data mining system, aviation maintenance structure of the framework of the final set of data mining system, aviation maintenance methods and steps to achieve ;Analysis of the characteristics and definition of data mining to build a data mining model for aviation maintenance, aviation maintenance and to make this data mining steps.Rough sets and time series for the similarity and other related technologies in-depth analysis of proposed and Rough set reduction and time-series similarity search methods and steps, using Rough Jane and differential matrix, simplifying decision-making table and get Optimal reduction set.In this paper, time series similarity search, the establishment of a certain aircraft components maintenance of the data curve trends, based on trends for the future aircraft components to predict failure rates, using the training set the training of the data mining model, experimental results show that the model can be effectively predict the next phase of aircraft components failure rate, can effectively increase the level of aviation maintenance intelligent decision-making.
