A hybrid approach for quantitative assessment of construction projects risks: The case study of poor quality concrete

This research presents a new fuzzy-based approach for quantitative assessment of construction projects risks. Using the proposed approach, the risk is decomposed into internal and external root causes prompting it and the probability of occurrence of risk is assessed by fault tree analysis (FTA). The impact of identified risks is then assessed by event tree analysis (ETA) considering the possible negative scenarios arising from the occurrence of...
