Abstract

Open Model Interface (OpenMI) technology can construct standardized components with unified timing interface and standardized data interaction. This provides a standardized method for integrating multiple models with different interfaces and functions. This paper briefly introduces the operation principle of OpenMI technology and the process of model standardization, and describes the seven key steps of model transplantation by taking the one-dimensional hydraulic model of the Yellow River as an example.

Highlights

Multi model integrated simulation technology of water conservancy is to apply the interface technology of computer software to the model interface, focusing on the standardization of the interface between model in order to use the same interface format for any model and increase the convenience and scalability of model combination
The European Commission on water framework has developed the standard of open model interface (OpenMI), which is a standard and rule for model integration
Many scholars use the standard interface of OpenMI to realize the coupling integration of models, for example, the Danish Hydraulic Institute developed the MIKE system software—MIKE SHE[2], Zhou Huaye put forward the distributed data interactive mechanism in the process of the model integrated model on the basis of the description and analysis for the timing driving integrated model application [3], Shi feiran developed model simulation platform based on cloud computing by using OpenMI technology standard [4], Lei Sihua etc. developed soil moisture prediction model by using OpenMI technology [5]

Summary

Introduction

Multi model integrated simulation technology of water conservancy is to apply the interface technology of computer software to the model interface, focusing on the standardization of the interface between model in order to use the same interface format for any model and increase the convenience and scalability of model combination. The European Commission on water framework has developed the standard of open model interface (OpenMI), which is a standard and rule for model integration. It can transplant and transform the models based on time series. Many scholars use the standard interface of OpenMI to realize the coupling integration of models, for example, the Danish Hydraulic Institute developed the MIKE system software—MIKE SHE[2], Zhou Huaye put forward the distributed data interactive mechanism in the process of the model integrated model on the basis of the description and analysis for the timing driving integrated model application [3], Shi feiran developed model simulation platform based on cloud computing by using OpenMI technology standard [4], Lei Sihua etc. This paper first introduces the operation principle of OpenMI technology, and describes the standardization process of using OpenMI technology. Taking the one-dimensional hydraulic model of the Yellow River as an example, it introduces the key steps of transplanting and transforming the existing model
