%A C.H. Rosa %A A. Ruszczynski %T On Augmented Lagrangian Decomposition Methods for Multistage Stochastic Programs %X A general decomposition framework for large convex optimization problems based on augmented Lagrangians is described. The approach is then applied to multistage stochastic programming problems in two different ways: by decomposing the problem into scenarios and by decomposing it into nodes corresponding to stages. Theoretical convergence properties of the two approaches are derived and a computational illustration is presented. %C IIASA, Laxenburg, Austria %D 1994 %I WP-94-125 %L iiasa4089
