Abstract: Multi-resolution (MR) modeling is a practical problem for complex adaptive system modeling and distributed simulation that need to be solved urgently. On the basis of analyzing the organization structure and evolution way of multi-resolution models, Agent-DEVS is extended by adding multi-resolution modeling level and relevant tuples. MR-Agent-DEVS is presented as a multi-resolution specification. And it is introduced into the modeling and simulation of emergency material supply. Coupling model and simulation flow are designed. And member models and typical messages are proposed. The experimental results show that MR-Agent-DEVS model can simulate the behaviors of emergency material supply and it has more timeliness, greater flexibility, and better consistency than Aggregation and Disaggregation method and Selected Viewpoint method, which is more favorable for reducing the system load. Though the complexity of MR-Agent-DEVS model is increased to an extent because of multi-resolution control, execution efficiencies of MR-Agent-DEVS and Agent-DEVS models are extremely similar, which verifies the practicability of MR-Agent-DEVS model.
