Abstract: Pedestrians escaping from the architecture are restricted by limited time and space. There are so many different exits, channels and bottleneck. Three kinds of facilities layout were designed to be initial schemes. The shortest escaping time was estimated by the different bottlenecks. Then, a safety escaping model based on the facilities layout and dynamic information was proposed, and the escaping time, area density and evacuation efficiency were analyzed by the simulation. The research indicates that by calculating and simulating the model can estimate the evacuation time for different schemes, and the result can provide some advices for facilities layout.

Journal of System Simulation
Abstract: In order to improve the versatility of electronic warfare scene simulation and reduce the repeated development, a parametric modeling approach was proposed. Based on the visual simulation development model of Vega Prime, the modular simulation architecture was designed to provide a unified design structure for parametric modeling. The method of parameter extraction and description was researched to standardize the design of simulation model parameters. Parameter constraint rules were researched to associate model parameters, avoid the conflict between parameters, and simplify parameter instantiation. A parametric visual simulation system of electronic warfare was designed and implemented. The parametric modeling process …
