MARTINS ALVES, Carlos José  and  MARTINEZ RODRIGUEZ, José Bienvenido. Optimal Design of Pumped Water Pipelines. RIHA [online]. 2015, vol.36, n.1, pp. 111-124. ISSN 1680-0338.

The use of optimization techniques in the design of water supply systems has advanced over the years. However, complexity of these algorithms has prevented its general use in practice. In this study an algorithm was developed for the optimal design of pumped water mains including determination of number, capacity and location of required pumping stations, applying a dynamic programming algorithm. The pipeline is divided in sections with a probable pumping station at the beginning of each section. The algorithm calculates capital and energy costs for each possible diameter for every section. The chosen alternative is the one with minimum total cost. To verify the proposed algorithm a case of the literature optimized with a model of Ant Colony was tested which produced similar results.

Keywords : water pipelines; optimal design; dynamic programming.
