INCORPORATING HUMAN RESPONSE TO NUCLEAR EFFECTS INTO DISTRIBUTED INTERACTIVE SIMULATORS

Present Distributed Interactive Simulation (DIS) simulators do not include provisions for battle hazards or degrading of weapons system effectiveness due to human response to them. HTI will design an Adaptive Response Filter (ARF) that will add human response degradation to any simulator on the DISNET without requiring any modification to the simulator or to the net. Every entity in a DIS simulation exists solely by its issuing and responding to messages called Protocol Data Units (PDUs). By intercepting and modifying these PDUs, ARF will give the effect of degraded response, both from the view from the affected simulator and its view (representation) to the rest of the simulation. ARF will connect between a simulator and the DISNET, bi-directionally classify PDUs on the fly, and either alter or pass them through depending on the nature of the weapons effect being played. In the process, ARF will log pertinent data for postmortem analysis of system response. Initially, the ARF swill impose time delays based on the extensive research conducted by DNA-RAEM (Kehlet) and be controlled by a DNA player or proctor. This will greatly extend the effectiveness of the simulator while being economical and simple to install and operate.
