Embodiment Construction

[0025] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0026] figure 1 It is the core flow chart of the technical solution of the present invention. The specific implementation steps of this method for fuzzy evaluation of sector traffic situation based on objective indicators are as follows:

[0027] Step 1: Analyze the data indicators that reflect the traffic situation of the sector, and establish an objective multi-level evaluation indicator system.

[0028] Analyze the indicators that can reflect the traffic situation of the sector, and evaluate the overall operating status of the sector, the spatial distribution of aircraft and the situation of flight delays, to more comprehensively describe the traffic situation of the control sector. Build a multi-level sector situation indicator system, such as figure 2 . The indicators in the indicator system are explained as follows:

Abstract

The invention relates to a sector traffic state multilevel fuzzy evaluation method based on objective indicators. The method comprises the following four steps: firstly, analyzing data indicators reflecting a sector traffic state to construct a multilevel evaluation indicator system; secondly, performing correlation analysis on indicator sets of different evaluative dimensions in the evaluation indicator system by adopting fuzzy clustering, and designing a reasonable sector traffic state indicator evaluation scheme according to a clustering result; thirdly, introducing a subjective-objective combined entropy weight method, eliminating subjective identification blindness and determining the weights of different level indicators in the indicator evaluation scheme; lastly, setting fuzzy evaluation grades, designing a corresponding membership function based on the data frequency of each indicator sample in the indicator evaluation scheme, calculating the comprehensive evaluation vector of the sector traffic state by using a proper fuzzy composition operator, and judging the sector traffic state level.

Description

Technical field: [0001] The invention relates to the research on sectoral traffic situation evaluation, in particular to a multi-level fuzzy evaluation method for sectoral traffic situation based on objective indicators. Background technique: [0002] With the rapid development of my country's national economy, the contradiction between the increasing air transportation demand and the current supply capacity has become more and more significant. How to objectively, accurately and comprehensively evaluate the airspace operation situation, especially the evaluation of the control sectors including air routes / airways and other major flight channels, is an important issue of current research. Through multi-dimensional comprehensive evaluation of sectoral traffic situation, it can provide effective support for airspace planning and design, equipment and facility construction, and flow management strategy formulation, and help to form scientific management decision-making and operation...
