A DEVS Visual Front-End Interface for Model Reusability and Maintainability

Abstract

Modeling is important in developing simulations. Due to the modeling process that establishes the relationship between the models determines the overall simulation flow and behavior of the models, so it requires the formulation of the overall structure and clear relationship expression. In case of DEVS, which is a discrete event simulation specification technique, modeling is performed by combining atomic models and coupled models. This process is performed in an abstract form and is expressed in a programming language. Therefore, it takes a lot of time and effort to get clear specification and understanding in DEVS modeling process and interpretation process, and it is not intuitive. In this paper, we introduce a DEVS based visual front-end interface that can reduce the cost of the modeling process to solve these difficulties. The DEVS visual front-end interface provides an environment for visually checking and modifying the modeling structure, and also provides skeleton code based on the modeling structure data. In addition, a program for maintaining consistency between source code and modeling information data is also presented in this study.
