ABSTRACT

Infrastructure asset management (IAM) aims at maintaining, in the long term, the ability of the infrastructure to provide users with a service of acceptable quality at a tolerable cost for impacts on society and the environment. This long-term objective involves a crucial issue concerning the consistency of medium-term renewal budget planning and short-term works programming. A literature review concerning the pipe lifetime concept and decision aid methods facilitates investigating this issue in depth and, ultimately, proposing a long-term simulation approach to help to improve the decisional process regarding infrastructure renewal.
