Abstract

Even with recent enhancements, computation times for large-scale multistage problems with risk-averse objective functions can be very long. Therefore, preprocessing via scenario reduction could be considered as a way to significantly improve the overall performance. Stage-wise backward reduction of single scenarios applied to a fixed branching structure of the tree is a promising tool for efficient algorithms like stochastic dual dynamic programming. We provide computational results which show an acceptable precision of the results for the reduced problem and a substantial decrease of the total computation time.

Acknowledgments

Jitka Dupačová has initiated this project and we have worked together till the very final form of the article, unfortunately, she passed away during the publication process. I would like to dedicate this paper to Jitka, for her restless guidance, knowledge, patience and care. The research was partly supported by the project of the Czech Science Foundation P/402/12/G097 ’DYME/Dynamic Models in Economics’.
