Extend SRML schema based on DEVS: an executable DEVS language

This paper analyzes the significance of the representation and reusability of SRML when being used in simulation models as well as its drawbacks. The paper also discusses the ways to extend SRML schema based on DEVS. The emphasis is placed on the elaboration of mapping DEVS onto SRML schema to formulate SRML´s basic syntax and semantics for the structure and behavior representation of atomic model and coupled model. The model structure, such as property, input interface, output interface and sub-model composition, are described by a group of XML marks. The model behavior, such as external transition, internal transition, output and time-advance functions are described by script language and a group of standard interface offered by SRML simulator in script marks. The paper then reviews the SRML element architecture and finally gives a simulation demo of using SRML to build differential equation model.
