Abstract

The invention discloses a big data-based method and system for predicting the variable sliding time and relates to the field of civil aviation information. The method comprises the following steps: analyzing historical data in an airport collaborative decision-making system database, extracting flight departure operation data from the historical data, determining main influence parameters of flight departure, setting a weight value and dynamically adjusting a weight proportion; modeling by adopting a gradient boosting tree model to obtain a variable sliding time dynamic estimation model, inputting actual data of main influence parameters into the variable sliding time dynamic estimation model, estimating probability distribution of variable sliding time, and calculating an expected value;performing visual display on the variable sliding time. According to the method, the variable sliding time is intelligently predicted through manual prediction based on the constructed A-CDM system. The large-area flight delay is prevented and relieved through big data visualization auxiliary decision making.

Description

technical field [0001] The invention relates to the field of civil aviation information, in particular to a method and system for predicting variable sliding time based on big data. Background technique [0002] China's civil aviation industry is developing rapidly, but the current level of informatization construction in the civil aviation industry is relatively lagging behind: in terms of hardware, especially the level of network construction lags behind business development, there are problems such as incomplete coverage and limited transmission speed; in terms of software, there are A large number of redundant construction, data islands, lack of data interconnection, and the system urgently needs to be upgraded. In the face of challenges, the civil aviation industry hopes to make full use of modern information technology to provide passenger and cargo transportation guarantee and digital management, visual presentation, and intelligent support for civil aviation airpor...
