Originální abstrakt

The applicability of stochastic programming models and methods to PDE constrained stochastic optimization problem is discussed. The problem concerning the transverse vibration of a string is chosen. Therefore, the corresponding mathematical model involves a PDE-type constraint and an uncertain parameter related to the external load. A computational scheme for this type of problems is proposed, including discretization methods for random elements (scenario based two-stage stochastic programming) and the PDE constraint (finite difference method). Several deterministic reformulations are presented and compared using numerical and graphical results.
