A Novel Method for Qualitative Modeling and Simulation Based on XML

The qualitative simulation field has developed remarkably in theory of algorithms, while relatively backward in modeling methodology. In this paper, a novel qualitative modeling and simulation approach based on XML (extensive markup language) is proposed, which greatly improves the efficiency of modeling, enhances the reusability, scalability and standardization of qualitative modeling and simulation. On the basis of theory studying of qualitative simulation algorithms and component-connection modeling, the model library design proposal is described by XML markup language. Some specific instances of the model fragments are introduced in relation to components of qualitative simulation model. The component-connection library (XML documents) will be parsed and transformed into a qualitative simulation QDE (qualitative differential equation), which is the input and initialization of qualitative simulation process.
