The effectiveness of the traditional risk analysis approach is enhanced by the integration of the fuzzy logic and Multi-Criteria Decision Making (MCDM) methods. In fact, human decisions are ambiguous and blurred and do not fit to express with absolute numerical values. For this reason, it is more realistic to use verbal variables in modeling human decisions. In this paper, a new fuzzy based hazard

Quantitative risk assessment (QRA) approaches systematically evaluate the likelihood, impacts, and risk of adverse events. QRA using fault tree analysis (FTA) is based on the assumptions that failure events have crisp probabilities and they are statistically independent. The crisp probabilities of the events are often absent, which leads to data uncertainty. However, the independence assumption leads

The weight parameter plays an important role in groundwater quality assessment. Importance scale weighting model (ISWM) and entropy weighting model (EWM) are the most common weighing models in conventional literatures. However, ISWM is significantly by the experts’ subjective cognitions, which makes it difficult to generate a unique weight parameter and water quality index (WQI). EWM often neglects
