Public ISBD Titre de série : Water resources research, n°9 Titre : Short-term, single, multiple-purpose reservoir operation : importance of loss functions and forecast errors Type de document : texte imprimé Auteurs : Datta, B. ; Burges, S. J. Année de publication : 1984 ISBN/ISSN/EAN : CI-06259 Note générale : Short-term operation policy for multipurpose reservoirs can be derived from an optimization model with the objective of minimizing short-term losses. Contribution of such loss functions requires the definition of target values for the decision variables, assessment of reliabilities with which inflows can be predicted, and an explicit statement of operational objectives. Formulation and evaluation of a model is complicated by the uncertainties inherent in the prediction of future stream flows and by controversies about the criteria of evaluation. We discuss theses issues and illustrate some of our arguments with simple numerical experimental.
