“…CONCLUSIONS DS-eCD++ offers an advanced simulation engine by integrating dynamic structure DEVS and the real-time simulation engine seamlessly. The simulation engine supports varied dynamic structure change forms [15] and the real-time simulation. DS-eCD++ expanded the major software components of eCD++ and advanced adaptability to the real-time environment.…”

We present an improved simulation engine that combines Dynamic Structure DEVS with a real time simulation engine (eCD++). The improved simulation engine is implemented includes an advanced dynamic structure real-time experimental environment to adjust the model structure automatically according to the changes in the internal/external environments. The existing abstract simulators were redefined to adapt to dynamic structure. In addition, a new abstract simulator implements the structural change behaviour of Structure Agent that executes the structural changes.

“…Theatre specifically addresses modeling and simulation of complex systems which are component-based [7], timed, mobile and whose structure can change during runtime [3,23,29,30]. Such systems are not adequately supported by conventional modeling and simulation (M&S) tools where the structure is often assumed to be static and dynamism only relates to state changes caused by the occurrence of events.…”

This paper proposes an agent infrastructure (Theatre) centered on Java for distributed simulations over High-Level Architecture/RunTime Infrastructure (HLA/RTI). The architecture rests on actors (agents) as the basic building blocks. Actors have a public message interface and encapsulate a state of local variables and a behavior patterned as a finite state machine. Actors interact with one another by asynchronous message passing. At the system level, theatres are used as the execution platforms for actors. Theatres naturally map on to HLA federates. Actors can migrate between theatres for load-balancing concerns, or in response to (re)configuration operations of dynamic structure systems. The paper introduces Theatre and demonstrates its application to a complex simulation model based on unmanned aerial vehicles (UAVs). The case study is an open agent-based distributed model where mobile agents follow communication patterns established at runtime.
