Choosing Models of Appropriate Resolutions for Simulation: A MRM Approach

Multi-resolution modeling (MRM) is widely used in manufacture industry, environment science (climate, geometry, map), science (material, biology) and so on. Dozens of theories and methods are proposed to MRM. However, most of these MRMs are not designed for simulation, which leads to MRM failures in terms of information loss, consistency maintenance and resolution changes. To solve these failures, this paper introduces Connectororiented Resolution State Chart-based System (CORES): a novel MRM approach with emphasis on choosing appropriate resolutions for simulation. In CORES, Resolution State chart, a UML state chart, is modeled to specify the resolution changes. And Connector, the connection of different resolutions, is proposed as a standby part to fulfill the four requirements on relationships between models of different resolutions. Finally, a dimension-variable linear system is modeled to demonstrate CORES approach, and the numerical results verify our approach.
