A dynamic structure DEVS algorithm Flexible Dynamic Structure DEVS is introduced in this paper. The algorithm is a salient supplementary of the Real-Time DEVS-based experimental environment we proposed before. By adapting the system organization to the changing internal/external environments while the systems are in progress, the functionality of the experimental environment is improved greatly. Consequently, it is possible to build more reliable and flexible Real-Time systems. This paper describes the abstract simulators for dynamic structure DEVS; moreover, the implementing process is presented to show how the dynamic structure abstract simulators work seamlessly with the regular DEVS simulating engine. The Real-Time DEVS-based experimental environment with the dynamic structure function exploits a new space to build reliable and adaptive Real-Time systems.
