yangtze Bayesian Network
Description
Towards system-theoretic risk management for maritime transportation systems: A case study of the yangtze river estuary.
Format
A discrete Bayesian network to determine the probabilities and consequences of accident scenarios in maritime transportation systems. Probabilities were given within the referenced paper (some inconsistencies in the numbers provided). The vertices are:
- AssessmentFailure
Assessment failure (Yes, No);
- AvoidanceRules
Strengthen the study of international maritime ship collision avoidance rules (Adopted, Unadopted);
- CautiousDriving
Cautious driving to keep lookout in the cautionary area of YRE (Adopted, Unadopted);
- Collision
Collision probability (Yes, No);
- CompetentCrew
Failure to have a competent crew (Yes, No);
- ConsequenceCollision
Collision consequence (Serious, Moderate, Minor);
- ConsequenceContact
Contact consequence (Serious, Moderate, Minor);
- ConsequenceSinking
Sinking consequence (Serious, Moderate, Minor);
- Contact
Contact probability (Yes, No);
- CrewTraining
Strengthen crew training on operation in narrow and crowded waters (Adopted, Unadopted);
- EarlyMeasures
Failure to take early measures (Yes, No);
- EquipmentFailure
Operation equipment failure (Yes, No);
- GrossTonnage
Gross tonnage (< 3000 tons, 3000-10000 tons, > 10000 tons);
- HardwareMaintenance
Strengthen ship hardware maintenance and management (Adopted, Unadopted);
- ImproperStowage
Improper stowage (Yes, No);
- InadequateCommunication
Inadequate communication (Yes, No);
- NegligentLookout
Negligent lookout (Yes, No);
- NoGiveWay
No give way (Yes, No);
- QualifiedCrew
Strengthen the supervision of competent crew according to law (Adopted, Unadopted);
- ResourceManagement
Enhance teamwork resource management training on the bridge (Adopted, Unadopted);
- SafetyTraining
Strengthening crew safety awareness training (general) (Adopted, Unadopted);
- ShipAge
Ship age (<10 years, 10-20 years, > 20 years);
- ShipTracking
Strengthen ship tracking management (Adopted, Unadopted);
- ShipType
Ship type (Carrier/Container, Tanker, Other ship);
- Sinking
Sinking probability (Yes, No);
- SupervisingCompanies
Strengthen the inspection of the effectiveness of safety management of supervising shipping companies (Adopted, Unadopted);
- SupervisionVessel
Strengthen the supervision of inland river vessel companies by the YRE port and navigation department (Adopted, Unadopted);
- TrafficFlow
Traffic flow (Heavy, NormalOrLow);
- UnsafeSpeed
Unsafe speed (Yes, No);
- Visibility
Visibility (Poor, Good);
- Wind
Wind (>= Category 5, < Category 5).
