Risk-based asset management focuses on prioritizing the most critical assets by evaluating their risk of failure. A typical way to determine the risk of failure is by assessing the asset’s likelihood of failure and its consequence of failure. The goal of this paper is to present a consequence-of-failure model using a weighted-sum multicriteria decision-making method to evaluate the economic, social, and environmental consequences of wastewater pipe failure. The model incorporates 14 factors consisting of pipe characteristics and demographic parameters arranged into a hierarchical model to determine one final consequence-of-failure score. The analytic hierarchy process (AHP) was used to determine the …
