Development of Risk-based railway safety management system architecture

초록

Organizations should have a public arrangement to guarantee safety of own business activities through policy, resource and order. The arrangement is called Safety Management System (SMS). SMS contributes to efficient control and monitor for prevention of potential hazard. It can also identify ability that the organization meets safety standards. SMS which is based on risk has five steps. Those are analysis of problems, development of requirement for resolve, establishment and fulfillment of a formal safety plan and application of PCDS cycle to safety activities. This report organizes the overall cases which architecture tools for all subjects concerning about rail safety supervisor is applied. Roles of the subjects assigned with safety activities and data exchange. The roles are classified as regulator, operating agency (TU, IM), system provider, independent rating agency and accident investigation board. SMS draws the following conclusion. Those are investment priority for safety improvement, quantitative analysis comparing with investment costs and accident prevention costs. The government enforces a safety management requirement to railway supervisor. After that, a plan based on the requirement which the supervisor has submitted should be approved. For continually management of the railway safety, the plan should be re-evaluated each year. Considering the above conditions, a development model would be produced by using Cradle S/W as architecture tools to facilitate upgrade and analysis of function after the development. It is also based on SE standard (IEC15288)
