OpenMI技术在水文模型集成中的研究进展

针对传统的模型集成方法难以规范化和模型接口难以标准化等问题,欧盟水框架委员会建立了开放式模型接口标准OpenMI(Open Modeling Interface),通过该接口标准,模型可以实现并行运行且共享每一时间步信息,在数据交换和模型链接机理上具有一定的优势。该文在分析了OpenMI工作原理和核心技术的基础上,着重阐述了OpenMI技术在水文模型集成中的研究进展,并指出OpenMI技术目前存在无法支持分布式模型集成以及缺乏可视化界面与人机交互等缺陷,而且在对模型间的数据请求响应机制以及交互数据的容错处理和中断处理机制方面仍有待完善。

Research Progress of OpenMI Technology in the Integration of Hydrological model

Targeting at certain problems of the traditional model integration method and Model interface such as difficult to be standardized, the EU Water Framework Committee provides an open interface standard model (Open Modeling Interface), through this interface standard, the model can be run in parallel and share information for each time step. It has certain advantages in the exchange mechanism and model data link. This paper mainly analyzed the working principle and core technology of OpenMI, and described the OpenMI technology in model integration. It was pointed out that there are still problems in OpenMI technology such as failure to support distributed model integration and lack of visual interface and human computer interaction. Besides, there is still a lot of room for development in the research on the mechanism of data request response and the mechanism of fault tolerance and interrupt handling in the model.
