Aiming at the reservoir remaining capacity decision-making in real-time optimal operation of water resources system,inflow forecasting information and the fuzzy and random characteristics of remaining capacity are discussed and described fully by using cloud model which is used in artifical intelligence field.By digging into history knowledge(uncertainty reasoning rules),cloud decision-making model for remaining capacity is established,and cloud decision-making method is given according to inflow which is forecasted based on forecasting period and remaining period.The model and method are applied to the remaining capacity decision-making of Longyangxia reservoir in 2000,which indicates that 77.3×108 m3 remaining capacity of reservoir should be used to confirm economical storage line of real-time optimal operation in 2000,this will produce 1.48×108 m3 more power benefits than that in real operation.
