A Method for Ship Data Application Based on Blockchain and Dynamic Surrogate Model
The blockchain technology was introduced to meet the requirements for controlled multi-party data sharing and data application in the field of ship design and research.A blockchain basic system was established for data management and application service.The program based on dynamic surrogate model was developed to predict the ship resistance by using random forest algorithm and dynamic sampling method,and the function integrating the program with the blockchain basic system was achieved.A data set of surface vessel resistance was taken as an example to simulate the scenario of multi-party data sharing and application.The proposed approach and procedure had the ability to achieve the design function and be used in practical applications.
