基于知识元网络的突发事件模型组合调用

Emergency Model Integrate Based on Knowledge Element Net

随着突发事件复杂性的增加,如何实现模型的组合调用成了科学与高效应急的关键。本文结合突发事件应急决策的特点和基于网络的模型组合方法,基于知识元网络和模型层次表示法,提出了一种通过构造动态模型组合网络解决模型组合调用问题的方法。该方法借助不同层次模型与知识元属性之间的关系构建模型组合网络,从而将模型组合与知识推演动态结合起来,即实现了对事件情景的动态捕捉,又保证了组合关系的合理性,同时很好的解决了组合模型之间数据契合度问题。

With the growing complexity of emergency, how to accomplish model integration is increasing became the key component to handle emergency scientifically and efficiently. A dynamic network model integration method based on knowledge element net and the model hierarchy representation method was developed by combining the characteristics of the emergency decision-making and the model integration method based on network. The method using the relationship between the attribute of knowledge element and the model parameters to construct a model integration network, which make model integration based on knowledge reasoning. By this method, we can catch the change of decision-making environments, ensure the integrating degree between two models and solve the data mapping problem.
