On a mixed zero–one separable non-linear approach for water irrigation scheduling

Abstract

We present a mixed zero–one separable non-linear approach to the optimization of the management of water resources used for agricultural irrigation purposes. It provides dynamic planning of the daily irrigation scheduling for a given land area by considering the irrigation network topography, water flow conditions and logistical operation constraints in order to optimize the use of water stored in a reservoir. We present a mixed zero–one separable non-linear program and a solution procedure that iteratively solves a mixed zero–one linear approximation of the model. We are not aware of any previous attempt to solve large-scale mixed zero–one separable non-linear programs of this kind. Some computational experiences on a large-scale real-life problem are reported.
