Abstract:

The multi-resolution formal description based on discrete event system specification (DEVS) has the ability of hierarchical and structured description, but the description of the intelligent behavior inside the module is relatively lacking, while Agent-based modeling can describe the characteristics of individual perception, behavior, communication, cooperation, learning and evolution. Under the framework of multi-resolution modeling, DEVS and Agent model descriptions are combined to provide the description capabilities for events, behaviors, mechanisms, etc. Based on the description of multi-resolution DEVS models, a formal model description method with coupling closure is proposed, which includes the description of the multi-resolution entity-level atomic model and the description of the multi-resolution system-level coupling model. According to the characteristics of the framework, the modeling process is standardized and realistic modeling cases are used to verify the effectiveness of the description framework.

Key words: complex product, multi-resolution modeling, behavior modeling, discrete event system specification (DEVS), formal description
