Fuzzy-logic-based network for complex systems risk assessment: Application to ship performance analysis

► Address scientific research in the area of ship safety assessment and engine health monitoring. ► Reinforce system health monitoring using improved scientific evidence in addition to classical visual inspection for improved decision-making. ► A good control design theory could not be a precondition on the integrity accuracy of fault diagnosis methods. ► Prevent marine accidents by good design, training, and operation in an appropriate systematic management system and controls.
