TL;DR: A comprehensive review on the application of multi-criteria decision-making (MCDM) literature in the field of infrastructure management is presented in this paper, which identifies trends and new developments in MCDM methods.

TL;DR: In this article, a fuzzy logic is employed to derive fuzzy probabilities of basic events in fault tree and to estimate fuzzy probabilities ( likelihood ) of output event consequences, which can help professionals to decide whether and where to take preventive or corrective actions and help informed decision-making in the risk management process.

TL;DR: The traditional AHP is modified to fuzzy AHP using fuzzy arithmetic operations and the concept of risk attitude and associated confidence of a decision maker on the estimates of pairwise comparisons are discussed.

TL;DR: A Bayesian Belief Network model is presented to evaluate the risk of failure of metallic water mains using structural integrity, hydraulic capacity, water quality, and consequence factors to justify proper decision action for maintenance/rehabilitation/replacement (M/R/R).

TL;DR: In this article, the concept of intuitionistic fuzzy set is applied to AHP, called IF-AHP to handle both vagueness and ambiguity related uncertainties in the environmental decision-making process, which is demonstrated with an illustrative example to select best drilling fluid (mud) for drilling operations under multiple environmental criteria.
