Abstract

There are many implementations of DEVS Modeling and Simulation in various computer languages and software tools. Most of them focus on modeler-friendly approaches which mean a user should have knowledge of modeling and computer languages. In this paper, we introduce high and low level design methodology to help domain experts (who might not have an in-depth understanding of DEVS modeling theory) solve their domain problems with DEVS modeling and simulation software called MS4 Modeling Environment (MS4 Me). The tool enables high level model design through a sequence diagram converted to a System Entity Structure (SES) document representing a coupled model. The template DEVS models generated from the SES are written to constrained natural language called DEVS Natural Language (DNL) to express DEVS atomic modes1 which MS4 Me displays to a state diagram as a low level model design. The state diagram contains detailed information from the domain experts who provide logic, variables, and message types for each atomic model. More in-depth technical implementation details are provided by DEVS modelers working together with domain experts. In this manner, MS4 Me provides a collaborative DEVS modeling and simulation environment for domain experts and DEVS modelers.
