Abstract :
A dual dynamic programming (DDP) technique for staircase linear programs was applied to problems arising in multistage scheduling of hydroelectric power systems. The approach has some similarity to nested Benders´ decompositions (J.F. Benders, 1962). The contribution is a computational strategy to arrange the iterations so as to improve convergence over the standard DDP approach. The application also favors use of relaxation in the subproblem, and this is discussed.<>
