열차제어시스템(mock-up)의 위험원 분석을 위한 Type과 Technique의 선정에 대한 연구

It has been studying actively that the process and the methodology for the safety security of the system suggested from international standards and domestic/abroad materials in Korea. However, these process & methodology can generate a lot of errors and deficiencies because the system is applied without considering the system characteristics and its scope (such as hardware, software, interface, etc.). Therefore, the type is defined as the safety process with the basis on general development process in this study, the potential hazards of the mock-up system which is developed are extracted thorough selecting a technique according to each type. In addition to it, the effect is compared and analyzed with various technique selection by each phase of the development process.
