“…When the numerator and denominator in equation [ 10 ] converge to infinitesimal respectively, there will be slight changes in different indexes, and the weight of entropy may cause big changes. In the improved method, for different indicators (for example, two evaluation indicators

and

), the corresponding entropy weight difference becomes, and we get equation [ 11 ].…”

“…Some scholars have carried out a series of studies on the tools and aspects of civil aviation operation safety management, and developed an effective safety risk decision-making framework, and introduced methods such as safety management system [ 8 , 9 ]. Some scholars also have developed traffic simulation models to identify hazards and analyze unsafe events [ [10] , [11] , [12] , [13] , [14] ]. Ni et al (2019) made civil aviation safety evaluation based on deep belief network and principal component analysis.…”

A problem of finding the best ways to ensure the efficient and safe traffic of aircraft (AC) based on the use of methods of mathematical computer modeling is presented. The choice of one of the alternative options for the AS structure and aerodrome infrastructure is considered. The formulation of the problem and a group of performance indicators for various interested parties in the use of the AS structure and aerodrome infrastructure, based on which the performance criterion is formed, are proposed. Each group is represented by quantitative indicators that can be calculated using computer mathematical modeling. The structure of the AS and the aerodrome infrastructure in the form of vectors consisting of the set of elements, such as the air route (AR) network, ATC sectors, and arrival and departure routes, are determined. A mathematical formulation of the problem of multidimensional conditional optimization is presented, taking into account the proposed restrictions and conditions of use, in which the considered options of the AS structure function. The description of mathematical models and algorithms for calculating the indicators are given. Examples of solving research problems using computer modeling methods based on the complex of simulation modeling of the air traffic management (ATM) system, which is designed to assess the structure of the AS and the infrastructure of the aerodrome, are given.
