Abstract
Uncertainty exists in both nature and human knowledge . For example , stream flow has random characters , and human satisfaction of water demand could not be described by an exact value . Greenhouse effects are enhanced due to increasing greenLhouse gases emitted by human activities , which may result in global climate change . Climate change will directly affect water resources , not only water supply but also water demand . The quantity of available water resources in wet and dry seasons 15 very different in Taiwan , 50 storage 15 required to store water for later uses . C limate change will influence water supply and demand , and thus may affect storage requirement , Storage capacity can be determined by linear programming , Traditional linear programming model contains only constant right hand side and coefficients of the objective function and constraints . However , there exists uncertainty in water resources systems. Uncertainty cannot be incorporated in the optimization framework if deterministic parameters are used , Some studies use stochastic process to describe uncertalnty . However , the stochastic method requires more information for analysis , which 15 impossible sometimes. Interval number fuzzy linear programming model (TNFLP) is proposed in this study and is applied to climate change impact assessment. The INFLP uses interval number to describe natural variability and fuzzy set to describe uncertainty of human decisions. The purpose of this study is to develop a procedure to evaluate the impacts of climate change on water resources. The procedure includes simulation and optimization models. The simulation model is to evaluate the climate change impacts on stream flows and demand. On the other hand, the INFLP is applied to find optimal storage capacity can be determined for future climate change condition.
