Assessment of aircraft prospects using a combined method of identifying preferences

Abstract Recently, the task of replacing the aircraft fleet has been in demand. The aim of the work is a multi-criteria assessment of aircraft and further decisions on their use. To solve this problem, it is proposed to use a combined method for identifying preferences, which is well algorithmic and allows you to take into account dependences on preferences in the multidimensional system of values of the decision maker. An algorithm based on the method of enumeration on a vector lattice has been developed. This algorithm helps the decision maker to take into account a large number of criteria and decide on the need to replace the aircraft. The advantages include a reduction in the calculation time. An interface for entering editing and preferences is proposed, which makes it possible to assess the feasibility of introducing new and withdrawing old aircraft.
