DDML: A Support for Communication in M&S

This paper presents a new approach to simulation modeling for discrete event systems that integrates two system design perspectives: object-oriented paradigm and system theoretic approach. The resulting formalism is a highly communicable visual language called DDML (the DEVS Driven Modeling Language) which federates modeling concepts from UML (Unified Modeling Language) and DEVS (Discrete Event System Specification). Such a combination facilitates the modeling process and improves communication between experts in the system domain and experts in modeling and simulation domain. A case study of urban traffic modeling is given to illustrate the use of DDML as a support for communication in Modeling and Simulation.
