Implementation of a DEVS-JavaBean simulation environment

A component-based simulation technology is brought up. This component-based simulation environment is based on the DEVS (Discrete Event System Specification) formalism and Sun's JavaBean technology. The DEVS provides a means of specifying a mathematical object called a system. JavaBean technology allows the modelers to drag and drop the software components visually and to combine specific JavaBean components to build their software systems. This paper introduces the DEVS-JavaBean simulation environment that contains basic JavaBean components of DEVS so that a modeler can visually change bean properties and relationships between JavaBeans. The reusability of components saves modelers in model development time. In addition, the convenience of JavaBean components such as drag-and-drop and visual modeling makes our simulation environment easy to learn and use.
