1.ITS impacts evaluation is a critical part of ITS deployment Compared with field tests, simulation models show prominent advantages in this area However, most of existing simulation models are unfit for this task So nearly one hundred important models in the world are fully reviewed in our research The sound models which may be suitable for ITS impacts evaluation are gathered and assessed Finally, the prospects and aspects that need improving are also indicated.
2.Since most of current network simulators are based on discrete event driven model and are built on the architecture of TCP/IP protocol stacks,design and implementation of the simulation model of physical layer protocol are the prerequisites for estimating the performance of upper layer pro- tocols.
3.For purpose of optimizing the performance of an adjustable linear oil damper, this paper establishes the generalized optimization mathematical model for its fluid system by use of a self developed platform, then analyses and evaluates the optimization results by means of MATLAB dynamic simulation package Prototype development and test results show that the mathematical models and dynamic simulation are accurate, the developed CAD system is efficient and substantial for engineering applications
4.The results of the simulation indicate that the model with ADAMS/Car could evaluate and forecast the dynamics of the model.
仿真结果表明,应用ADAMS/Car所建立的模型能较全面的评价和预测动力学性能。5.According to the evaluation system, an optimization model is established to avoid the phenomena that evaluation systems are apart from those models of choices of supply chain partners. Finally, simulation experiments by Genetic Algorithm and MATLAB are made to show the correctness and validity of the model.
