A safety management system is a information system. This system finds out hazards which could occur during safety management activities, and analyze and evaluate their natures, and then plan to take measures. Therefore accidents could be prevented. To establish the information system, robust architectures are required. A purpose of this research is to derive procedure of establishment in relation to developing safety management systems, which is needed to be advanced. To accomplish it, we reviewed a movement of architectures to establish electronic information and a movement of technology development. And then we led definitions of requirements and architectures development process from those that are based on review of the trends.

홍선호(Hong Seon-Ho),하재호(Ha Jae-Ho),김영태(Kim Yung-Tae) 한국철도학회 2009 한국철도학회 학술발표대회논문집 Vol.2009 No.5월

Of the rapid development of modern civilization development is one of the IT industry. The Network is the root of the discrete industry. Most of the Protocol is used by LAN and the TCP / IP. Slowly in the railway operation of this Network is being applied. It also used to train and they are operated. The concept of the road, the Network TCP / IP using a non-Star structure of the Main Unit and the Bus Network is designed to structure consists of the Network. This structure is a simplified DATA. Data of complex operations is easy to feel the speed limit is. In addition, all devices must be independent to the operating system with the ability to manage the operation and stability in terms of exactly how the transmission of Data is gonna work pass. And transmission occurs in the middle of the Noise and the device is available to manage the power. Noise in the power of the railway to ensure the efficient transfer of Data is by blocking. Also, by presenting the entire system's operational safety should be guaranteed the safety of the railway.

Railroad systems can be divided into the primary function for transporting passengers or freight and secondary function covering diverse environmental factors and interfaces. So, the most biggest and important reason and the goal of railroad systems is to satisfy the need for transportation based on the production and consumption of energy. Especially, the operation of safe systems is the inevitable element for achieving this objective. Performing this can be ultimately satisfied only when the relationship among operators, contractors, suppliers and assessors is established according to their missions. Therefore, we are trying to finding the way of approaching it systematically by reviewing which procedures and methodologies mission performers in various domains have to follow.
