A Study On Constructing Rail Energy Management System Applied SE Process Joo Uk Kim*, Ho Sung Jung, Hyung Chul Kim Korea Railroad Research Institute, Korea Systems engineering ensure that the performance in order to satisfy the the initial stakeholder’s requirements at a complex system. A complex system consist of subsystems and is designed to carry out the purposes of its own with certain functions and physical configuration. Rail Energy Management System is a system composed of subsytems that are integrated management system for railway power grid, intelligent railway substations, renewable energy association technology, maintenance-free energy storage technology, power management system of railway vehicles. It is important that not only system maximize the performance of each subsystem but also subsystems within the system carry out the purposes of the original system. Thus, according to the operating scenario, the stakeholder’s requirements traceability management is essential and it is very important to apply the SE methodology in order to construct the rail energy management system as a system. For this purpose, this studies were conducted on ways to apply SE methodologies to construct Rail Energy Management System. First, operational scenarios of Rail Energy Management System should be written. Second, Requirements based on operational scenarios should be driven, analyzed and refined. Third, a function model should be developed from requirements tracebility, Forth, non-functional requirements are assigned to the physical architecture. In this process we defines how to configure a physical interface to the internal architecture. Fifth, Written verification requirements in advance will be performed smoothly in a verification process. As stakeholder requirements traceability is applied to the system, it will help to better maintain the performance of the Rail Energy Management System.
