Research on Evaluation Method of Ship Equipment Environmental Adaptability

Aiming at the characteristics of environmental adaptability of ship equipment, this paper analyzes the possible environmental factors of ship equipment from three aspects: natural environment, mechanical environment and biochemical environment. The evaluation parameter system and model of ship equipment environmental adaptability are constructed. Based on the laboratory environment test data and the field-use test fault data, the membership degree describing the ship equipment environmental adaptability to single factor is constructed. A method of environmental adaptability assessment of ship equipment based on fuzzy comprehensive evaluation is presented. Finally, the rationality of the model and the feasibility of the method are validated by an example verification.
