When the number of subsystems or constraints is large, use of the maximum principle leads to laborious computational procedures. To get around these diffculties, an analytical lowering of the dimensionality or an iterative decomposition on the basis of variable clustering is proposed.  Ключевые слова Block problems of optimal control; iterative decomposition; variable clustering
