Traditionally, inflow forecasting models were used like black boxes. Users prepared the inputs at one end and received the outputs at the other end. In such an environment, the inflow forecasting models were aimed at generating inflow forecasts without any user intervention. This paper describes a new, user friendly, approach to inflow forecasting. It allows users to input their preferences, interactively, during the execution of the model and to generate inflow forecasts with which they feel comfortable.
