specific Embodiment

[0137] like figure 1 and Figure 4 As shown, the present invention discloses a congested airspace sector identification method based on multi-level matter-element entropy weight, which belongs to the field of air traffic management. The method first constructs a sector identification index system in congested airspace, selects the complete set of sector samples, calculates the sector congestion evaluation index, and performs normalization processing to determine the index threshold; then constructs a multi-level matter-element model, and calculates the index weight in a certain dimension , construct the matter-element sector to be assessed; determine the dimension level of the matter-element sector to be assessed, calculate the weight of each dimension, and calculate the comprehensive congestion level of the selected sector to be assessed. Specific examples are as follows:

Abstract

The present invention discloses a multi-level matter-element entropy weight-based congestion hotspot airspace sector recognition method and belongs to the air traffic management field. The method includes the following steps that: a three-level airspace sector congestion degree evaluation index system including a target level, a dimension level and an index level is established, the calculation or sampling method of indexes is established, evaluation indexes are calculated on the basis of evaluation sector sample selection, and index level threshold judgment is performed according to index numerical value distribution; a multi-level matter-element model is established, association degrees and index weights are calculated, a sector congestion dimension level is judged; and the calculation of a sector congestion dimension weight is determined on the basis of an entropy weight method, and a congestion hotspot airspace sector is recognized. According to the method of the invention, a sector congestion degree is comprehensively judged from a plurality of dimensions, technical support is provided for the research and development of control auxiliary decision-making system tools, and references are also provided for airspace planning, sector adjustment and the like.

Description

technical field [0001] The invention belongs to the field of air traffic management, in particular to a method for identifying a congested hot spot airspace sector based on multi-level matter-element entropy weights. Background technique [0002] Sector identification technology in congested airspace is an important technical basis for airspace planning and sector adjustment. It can effectively guide the implementation of flow management strategies and can more targeted management of unbalanced flow capacity. The U.S. enhanced traffic management system judges the congestion status of the sector according to the relationship between the capacity and flow by setting the capacity value of the sector. Some foreign scholars use queuing delay time and flight cancellation data to judge airport congestion, or use traffic complexity to describe the degree of congestion. The calculation methods of traffic complexity include complexity calculation based on geometry, dynamic system base...
