Optimal UAV maintenance periodicity obtained on the multi-optional basis

It is made an attempt to find some new method for an unmanned aerial vehicle maintenance optimal periodicity determination with the help of specifically introduced hybrid-optional functions entropy extremization. The prototypic approach is the use of alternatives individual preferences optimal distributions and the preferences subjective entropy maximum principle, proposed by Professor V. A. Kasianov (National Aviation University, Kyiv, Ukraine). It is obtained the optimal periodicity for an unmanned aerial vehicle maintenance on the entirely not probabilistic basis. Theoretical speculations are illustrated with the example calculation experiments. The necessary diagrams are plotted.
