一种基于区块链和动态代理模型的舰船数据应用方法

A Method for Ship Data Application Based on Blockchain and Dynamic Surrogate Model

引入区块链技术以满足舰船设计研发工作对多方数据受控安全共享和应用的需求。根据数据管理和应用服务功能建立一套区块链底座,基于随机森林算法和动态样本法开发舰船阻力动态代理模型预报程序,实现程序与区块链底座的功能集成。以水面舰船阻力数据为应用实例,模拟多方数据共享与应用场景。结果表明,论文方法能够实现设计功能,具备工程实用性。

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.
