We proposed an integrated simulator scheme for communication networks. The network modeling and Analysis methologies are firstly discussed along the design procedure of a network simulator, and then, the structure, kernel, and user interfaces are defined for the simulator. Finally, for the verification of our approach, simulations are performed for a simple queueing network and a pure ALOHA system using Ptolemy, a multi-paradigm simulation enviroment.

As the high performance computer system increases, improving of reality and usefulness causes the virtual environment of simulator to be used widely as training and assessment tool. Although some domestic companies have developed train driving simulators since about mid of 1990s, accumulation of technology and experience is not yet sufficient compared to foreign makers. This paper describes system composition, training and assessment regimes for high level train driving simulator. When the subsystems are designed, comprehension of train system is emphasized and the functions that simulator should provide are discussed.

The Training using a simulator comes into the spotlight as effective and safety training tool in a lot of fields. Driving simulator of KTX-II is for driver's actual training using virtual reality to be improved their ability of operation against when they are faced with urgent situation and various accidents. This paper describes the construction of the propulsion and brake model for KTX-II driving simulator and the utility of the model as a result in comparison with the design data of the real train.

In this paper, we propose a model that simulates the reflective waveform from underwater objects by means of Doppler effect, highlight and elongation phenomenon. Also, this paper presents a hardware Implementation of simulation model with the input and output parameters. The underwater target simulator consists of transducer, receiver, transmitter and control parts. According to the experimental results of the simulator, it carried out the performances of real target in response to transmission signal.

A time based software simulator for the PRT system operation is presented. The purpose of the simulator is to estimate the passenger transportation performance of the PRT system. In this paper, it is presented how the system is modeled in the simulator to estimate passenger transportation performance and the running algorithm of the modeled subsystem. An application sample is also presented to find the system's design parameter to satisfy the transportation needs.

Since container throughput is continually increasing, the main issues facing decision-makers at port container terminals are how to expand the existing container terminals and construct new container terminals. Simulations that support user needs require modeling tools that are both easy to use and sufficiently to reflect real world system. The object-oriented approach provides for both reusability and modularity that best fits these requirements. This paper present the design procedure a simulator for port container terminal that was based on the object-oriented approach. The simulator in order to model and simulate the TC-based container terminals is developed.

This paper focuses on a performance analysis model for optimizing the freight terminal design and layout using AutoMod simulator and numerical analysis. We developed a model to analyze the freiht terminal performance per unit time and the material handling cost based on both throughput and waiting due to conjestion. We developed computer program for this model and some sample results by both numerical method and AutoMod simulator are compared.

This paper describes the features of a transmission line and a wiring, and a design rule based on a demanded condition for a wiring. Like as the simulation of a circuit, by tracking the wiring path among parts that are disposed on PCB, we analyze the feature of the corresponding wiring using the design formula and rule. We implement a signal integrity simulator, which is capable of electrical and electronic simulation for the feature of a wiring signal and the corresponding signal, and the results are demonstrated.

The application of a reliable motion simulator can contribute effectively in the evaluation of the performance of a vehicle platform in the development stage of a small unmanned aerial vehicle (UAV). Therefore, the research on a reliable motion simulator can accelerate the development of UAV and decrease the relevant cost. In this paper, the design factors considered in the preliminary design stage of a 6 degree-of freedom motion simulator are defined and the motion range of the simulator is described on the basis of these design factors. The length, acceleration, and the required thrust of actuators with respect to the motion simulator under development are also predicted. The motion range can be increased and a suitable actuator can be selected and produced by applying these results in the manufacturing process of the motion simulator. Thus, the reliability of the motion simulators can be achieved during the actual design operation of the UAV.
