Parallel Hybrid Method Applied to Water Distribution Networks Scheduling [pdf]Paper  abstract   bibtex   
Problem description: The integral optimization of water supply systems presents various problematic aspects. Among these are the optimization of resources at the water treatment plants and the optimization of water transport, distribution and consumption. With regard to the optimization of the distribution networks, it is possible to distinguish between (1) the design of networks with a topology and characteristics that optimize both water transport and distribution, and operational and implementation costs; and (2) the search for planning and control strategies to minimize exploitation costs, according to the system constraints and supplies that have to be guaranteed. This work deals with this second kind of problems. More specifically, we consider the problem of distributing the volume of water supplied by the treatment plants (ETAP) between the different tanks comprising the network in order to meet consumer demand. This problem involves minimizing valve movements and pumping activations, and taking into account the constraints imposed on the system with respect to the tanks' minimum and maximum allowable levels. The difficulties posed by these optimization problems arise from their non linearity and the high number of equations to be solved, the non-explicit operational constraints that must be satisfied, the use of discrete variables, and the task of data acquisition and maintenance.
