Optimal operation of soil aquifer treatment systems considering parameter uncertainty

摘要

This paper presents a new methodology for determining optimal operation of soil aquifer treatment(SAT)systems considering parameter uncertainty. The problem of optimal operation of SAT systems is formulated and solved in a discrete-time optimal control framework by interfacing The SALQR(Successive Approximation Linear Quadratic Regulator)optimizer with the MSTS (Multiphase Subsurface Transport Simulator)model. Both deterministic and stochastic program- ming formulations have been solved. Through the use of first-order analysis of uncertainties, the uncertain of the water content due to the uncertainties of the simulation parameters are evaluated.
