AbstractMost urban distribution water mains are located under paved streets or roads. Despite an obvious interdependence between pipe and pavement deterioration, this interdependence has not yet been considered in frameworks that would optimize both simultaneously, which is the issue addressed in this paper. The deterioration processes of both pipe and pavement are considered to be deterministic, and some assumptions are made about the interactions between pipe breakage frequency and pavement condition. Total life cycle costs of both pipe and pavement are computed as the discounted costs of an infinite series of perpetual renewal cycles. Genetic Algorithm (GA) is used to find the (near) least cost strategy for scheduling multiple pipes and pavements in a network.
