Abstract
Рассматривается решение нелинейной задачи расчета конструкторских размерных цепей в условиях параметрической априорной неопределенности. Предложены методология синтеза решений многокритериальных задач стохастической оптимизации со смешанными условиями (MV-задач) и эффективный меметический алгоритм синтеза решений MV-задач. В качестве примера получены результаты решения задачи робастного оптимального проектирования двухступенчатого осевого компрессора в условиях стохастической природы входных данных.
Consideration was given to the formulation and methodology of the direct nonlinear design problem of structural dimensional circuits in conditions of a priori parametric uncertainty. It was shown that the solution of the direct nonlinear design problem of structural dimensional circuits can be reduced to the multicriteria problems of stochastic optimization with mixed conditions. Mathematical models and methods of the solution of multicriteria problems of stochastic optimization with mixed conditions were analyzed. A. N. Tikhonov method of the regulation of solution of incorrectly formulated problems was used as a computation method for the synthesis of quasi-solutions of incorrectly formulated problems. An effective memetic algorithm for the synthesis of the solutions of MV-problems was suggested. It is based on the genetic algorithm combined with the randomized path tracing method.
