AbstractA fuzzy-based approach to model the deterioration of large buried pipes using scarce data has been developed. The fuzzy risk model is used to plan the renewal of the pipe subject to maximum risk tolerance. This paper expands this approach to further explore pipe renewal strategies that could include various technologies as well as various scheduling schemes. It compares the strategies based on discounted costs and risk exposure. It demonstrates these concepts using data obtained for a prestressed concrete cylinder pipe and discusses model limitations and future research needs.
