Method and device for confirming minimum sample size of flight plan for airspace simulation analysis

Abstract

A method and device for confirming the minimum sample size of a flight plan for airspace simulation analysis can find a balance point between workload and accuracy, provide a data basis for airspace simulation modeling and evaluation analysis, can be popularized to post-analysis of airspace evaluation. When air traffic control monitoring historical data is used for evaluating an airspace operation state, air traffic control monitoring data with reasonable scale and proper precision is acquired for analysis. The method comprises the following steps: (1) calculating a Pearson correlation coefficient of a sector evaluation index; (2) analyzing the correlation coefficient difference to determine the minimum sample size: analyzing the evaluation index correlation coefficient of each day in a week, analyzing the evaluation index correlation coefficient of each week in the surroundings, analyzing the evaluation index correlation coefficients of every two weeks in the surroundings. the minimum sample size is determined through analysis and comparison of Pearls correlation coefficients of airspace simulation evaluation indexes of a control sector of a certain area in one day, one week, two weeks and three weeks.

Description

technical field [0001] The present invention relates to the technical field of civil aviation data processing, in particular to a method for confirming the minimum sample size of a flight plan for airspace simulation analysis, and a device for confirming the minimum sample size of a flight plan for airspace simulation analysis, which is between workload and accuracy Find a balance point to provide a data basis for airspace simulation modeling and evaluation analysis. Background technique [0002] Sample size refers to the number of units contained in a sample. Determining the sample size is very important, because if the sample size is too large, resources will be wasted; if the sample size is too small, the error will be too large, inconsistent with the actual situation, and affect the accuracy of the research. The minimum sample size refers to the lower limit of the sample size required to meet the research purpose based on the resources that the research can provide. ...

AI Technical Summary

Problems solved by technology

[0005] 1. The professional sample size determination method is very complicated, involving huge and complex data, many steps, and a large amount of calculation. Determining the sample size itself is a research direction of mathematics, and exploratory methods are not suitable for the daily operation of airspace modeling

[0006] The requirements of airspace modeling for simulation input data are mainly in terms of data content, but the requirements for the amount of data, especially the sample size of flight plan data, only put forward principled requirements, without quantitative standards and specific methods
