The algorithm can be applied directly to simulation models of dynamic systems that have no complete analytical description, and it form a part of the method of optimizing control using such models. The efficiency of the method is illustrated by the example of helicopter emergency landing.</p>Dynamic controllable systemimprovement of controlsimulation object modelemergency helicopter landing manoeuvresparallel algorithmДинамическая управляемая системаулучшение управленияимитационная модель объектаоптимизация маневров нештатной посадки вертолета
