Evaluation of marine fuel supply system state based on AEC model
ObjectivesIn view of the development demand of intelligent engine room of ships, in order to uncover the potential failure factors of equipment in advance, a new AEC health state evaluation model suitable for the ship's system and equipment is proposed.Methods This model combines the improved a...
