A Fermatean fuzzy fault tree and Bayesian network hybrid for collision and grounding risk in a congested strait

Collision and grounding remain the dominant accident categories in congested straits, where dense crossing traffic, sharp bends and strong currents act together with human and technical failures. Quantitative risk assessment in such waters is hampered by scarce failure data and b...

An Evidence-Derived Interval-Valued Fermatean Fuzzy MEREC-CRADIS Framework for Bread Wheat Cultivar Prioritisation under Water-Deficit and Saline-Soil Conditions

This study develops an interval-valued Fermatean fuzzy (IVFF) MEREC-CRADIS framework and demonstrates it using cultivar-by-environment measurements reported in a published two-season field study. Six Egyptian bread wheat cultivars are compared using six criteria derived solely fr...
