“…Water distribution system represents the arteries of a city, in which pipe failures are a regular occurrence when the residual strength of a deteriorated pipe becomes inadequate to resist the load on it (Skipworth 2002). Pipe failure incurs large economic and social costs both directly and indirectly, such as water and energy lost, repair cost, traffic delays, factory production lost due to inadequate water or service interruptions.…”

The water loss from a water distribution system is a serious problem for many cities, which incurs enormous economic and social loss. However, the economic and human resource costs to exactly locate the leakage are extraordinarily high. Thus, reliable and robust pipe failure models are demanded to assess a pipe's propensity to fail. Beijing City was selected as the case study area and the pipe failure data for 19 years (1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005) were analyzed. Three different kinds of methods were applied to build pipe failure models. First, a statistical model was built, which discovered that the ages of leakage pipes followed the Weibull distribution. Then, two other models were developed using genetic programming (GP) with different data pre-processing strategies. The three models were compared thereafter and the best model was applied to assess the criticality of all the pipe segments of the entire water supply network in Beijing City based on GIS data.

“…Paramount to such investment planning is the ability to estimate when a pipe has reached the end of its useful life. A variety of stochastic models exist to address this need, providing useful predictions of pipe cohort behaviour, vital for master investment planning [1]. However, for detailed proactive management pipe level estimation is needed.…”

“…5 Instrumento de ayuda a la decisión para la gestión de la red RAP (Adaptado por Skipworth et al, 2002) La renovación de las redes RAP forma parte de un proceso más global que es la gestión de la red RAP en conjunto. Proponemos adaptar la aproximación propuesta por Skipworth et al (2002), identificando los datos que deben ser considerados en el curso de nuestro análisis y las evaluaciones que permiten medir el desempeño de la red RAP. La recolección, puesta al día y el procesado de los datos son procesos gestionados en el marco del sistema de información de la empresa de agua.…”
