DEVS Formalism: A Hierarchical Generation Scheme
System reproduction model to the growing system structure can be provided to design modeling formalisms for variable system architectures having historical characteristics. We introduce a DEVS (Discrete Event System Specifications)-based extended formalism that system structure gradually grows through self-reproduction of system components. As extended-atomic model of a system component makes virtual-child atomic DEVS models, a coupled model can be derived from coupling the parent atomic model and virtual-child atomic models. When a system component model reproduces its system component, a child component model can receive its parent model characteristics including determined role or behavior, and include different structure model characteristics. A virtual-child model that has its parent characteristics can also reproduce its virtual-child model, which may show similar attributes of the grand-parent model. By self-reproducible DEVS (SR-DEVS) modeling, we provide modeling specifications for variable network architecture systems.
