【 摘 要 】

One of the most important pillars of optimized multi-purpose reservoir optimization models is the definition of a penalty or loss function. Due to the variety of operating goals and the complexity of the system, they often use alternative functions instead of using profit and cost functions, which only consider certain goals. These functions are the sum of several expressions that reflect the penalty or damages corresponding to the deviation from the desired values ​​(needs). In this case, one of the most important steps in developing an optimization model is to determine the coefficients and capabilities (parameters) of these functions. This paper uses a dynamic stochastic programming (SDP) model to optimize the operation of a multi-purpose tank. With the help of this model, the parameters of the damage function have been evaluated through sensitivity analysis. For this purpose, the criteria of reliability, reversibility, and vulnerability have been used. Studies show that these parameters are much more sensitive to changes in the power of functions than the coefficients of functions.
