La gestión de los activos y su renovación generalmente se planifican a nivel anual y operativo. Sin embargo, a nivel estratégico y táctico, las empresas de infraestructuras buscan modelos de gestión que permitan analizar sus activos, su evolución y la detección de aquéllos que deben ser renovados e incorporados antes en las planificaciones a medio...

Water supply and sewer networks are critical infrastructures that provide a basic service to society. However, these systems constantly age and degrade over time. In addition, since network infrastructures are so extensive in length, they require a significant investment in maintenance tasks. Hence, within the context of infrastructure asset manage...

Asset management in hydraulic infrastructures aims for the long-term sustainability of water distribution and wastewater networks. Strategic maintenance planning has thus been deeply analyzed in the literature for individual water and sewer pipes. However, water utilities do not plan and perform replacement activities on individual elements, but ra...

The water supply networks of many countries are experiencing a drastic increase in the number of pipe failures. To reverse this tendency, it is essential to optimise the replacement plans of pipes. For this reason, companies demand pioneering techniques to predict which pipes are more prone to fail. In this study, an Artificial Neural Network (ANN)...

We present a weighted sum model to calculate the risk index, which is equivalent to a priority index for the replacement of pipes in a network. This index is based on two factors related to pipe condition (probability of failure and supply pipe leakage flow), and three factors related to the consequences of pipe failure (non-served demand for suppl...
