GPSS(Graphic-based Power System Simulator) had been introduced before in an ex-thesis. GPSS is a Power System Simulator that is designed to provide friendly and highly interactive Graphic User Interface (GUI). In this Paper, GPSS was improved not for the education or the test, but as the instrument for a large-scale systematic analysis. To limit the difference between a theory and practical affairs, we reformed and added a lot of functions to the GPSS. And we have verified the real-systematic data.

In this paper the Graphic-based Power System Simulator(GPSS) program is introduced. GPSS is a Power System Simulator that is designed to provide friendly and highly interactive Graphic User Interface(GUI). The main features of GPSS are graphical free editing, quick and fine System-Drawing and Load-Flow analysis. Most of all, mapping power system data(only pure text information) into Graphic Data is of very practical use to power system designer and analyst.

To Provide pleasant building environment and the ease of maintenance and facility management, many new office buildings are being built as intelligent buildings. Building control systems which are employed in intelligent buildings require advanced types of controllers and varieties of control schemes. Designing and installation of these types of advanced building control systems take a lot of effort and also they are costly. In order to design these systems, it is necessary for the designers to have means to analyze and estimate the performance of control systems. In this paper, the results of the simulator for HVAC and elevator system are presented as the first stage of the development of the integrated simulator. For the development of simulator, ARENA which is the general-purpose software tool for the simulation with reinforced GUI is used.

As make a simulator including user interface functions like start & stop, load parameters, record and save, view 3D display has a real-like length and numerical value of sizes, represent real-shape of inner and outer part of robot, make the possible fast and slow selective observation as a adjust a step, receiving the images through the image device which attached in robot, so make a motion tester simulator of humanoid robot which coded by windows based GUI(Graphic User Interface) program with a MMI(Man Machine Interface) function that user can watch the environment which included robot and use a images. For implement this, we use a design data that converted data which made by use a CAD for Laser RP(Rapid Prototyping) progress into C coding for simulator programming. Using OpenGL, an API of graphic, it has a efficiency and detail of graphic operation. To make and test animation data, it has the option of save and resume in animation.

An integrated single-wafer processing tool, composed of multiple single wafer processing modules, transfer robots, and load locks, has complex routing sequences, and often has critical post-processing residency constraints. Scheduling of these tools is an intricate problem, and testing schedulers with actual tools requires too much time and cost. The Single Wafer Processor (SWP) simulator presented in this paper is to validate an on-line scheduler, and evaluate performance of integrated single-wafer processing tools before the scheduler is actually deployed into real systems. The data transfer between the scheduler and the simulator is carried out with TCP/IP communication using messages and files. The developed simulator consists of six modules, i.e., GUI (Graphic User Interface), emulators, execution system, module managers, analyzer, and 3D animator. The overall framework is built using Microsoft Visual C++, and the animator is embodied using OpenGL API (Application Programming Interface).

This study proposes a new approach to implement smart factory based on robot monitoring system for a small and medium sized enterprise. The simulator includes the forward kinematics and inverse kinematics analyzes of articulated robots. We also modeled the dynamics of the robot and made it possible to simulate it in the program. We studied the interface between the user and the monitoring programming system using the GUI environment of Windows OS, and it is configured to select the appropriate trajectory planning and control method. The reliability of simulator is illustrated by simulation test.

본 연구는 NIST사에서 개발된 FDS를 기반으로한 GUI환경의 전처리 프로그램의 개발에 관한 것이다. 개발된 프로그램은 GUI환경에서 임의의 직육면체를 생성하고 편집할수 있으며 또한 국립지리원에서 보유중인 DXF의 수치지도를 이용하여 지형에 관련된 모델링을 가능 하도록 하였다. 복잡한 지형의 모델링기능과 GUI 환경에서의 편의성은 FDS의 활용도를 높여줄 것이며 이를 이용한 화재 모사는 화재 발생시 진압/대피의 효율을 높여 화재에 대한 피해를 줄일 수 있을 것으로 판단된다.

발전계통 시뮬레이션은 CFO(전산유체역학)을 이용한 시뮬레이션으로서 다차원 미시적인 현상에 대한 시뮬레이션을 뜻한다. 주요 특징으로써 다수의 컴포넌트로 구성된 계통의 다양성으로 보일러, 급수계통, 증기계통, 복수계통 등 다양한 계통들이 존재하고 있다. 따라서 다양한 컴포넌트 모듈을 저장할 수 있는 GUI(Graphic User Interface) 기반의 시뮬레이션 툴이 필요하게 되었다. 현재 발전계통 시뮬레이션 툴의 문제점은 외국의 상용화 툴에 전적으로 의존하고 있으며 이는 곧 시뮬레이터 유지 보수의 어려움을 초래하게 되었다. 본 논문에서는 발전계통 시뮬레이션을 위한 컴포넌트 모듈의 생성, 모듈과 그래픽 라이브러리간의 연결, 유량-압력 알고리즘을 이용한 계통 Solver를 설계하고 멀티스레드를 이용한 복수개의 계통 시뮬레이터 구현 방법을 소개한다.

This paper presents a Windows graphic developed by the authors for the education and training of power system. Object-oriented programming is a major trend in computer software because it increases flexibility of large-scale software systems. An efficient platform for power system simulation applications has been proposed. This paper presents an intuitive Windows-based program for the power system analysis. The advantages of the object-oriented approach are demonstrated with an implementation of the graphical program. It provides a graphical interface for designing the one-line diagram of the bus and analyzing the output of the simulations. A graphical editor to visually edit the power system, diagram, results processing and exporting and graphic presentations.
