The Study on the architecture methodology application to rail energy management system

초록

System on Systems Engineering is the entity complexly composed of subsystems and carrying out the purpose of its own with certain functions and physical configuration. Architecture Framework is defined to common approaches to develop and present and synthesize architecture. 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 equipment, maintenance-free energy storage equipment, power management system of railway vehicles. As upsizing systems and developing technologies, the complexity of system increased. MBSE(Model Based Systems Engineering) using model and computer-aided tool become commonplace. MBSE bring results ?improving stakeholder communication, improving ability to manage the complexity of the system, improving product quality using assessable models, etc. In this study, using architecture framework a well-defined outputs and models of each view, I performed to improve reusability and universality of outputs and models. I studied based MNDAF(Military and Defense Architecture Framework), the unique domestic standard. MNDAF presents architures with 4 views ?all view, operational view, systems view, technical view. I studied to apply Rail Energy Management System to MnDAF. In order to design system, requirements should be acquired and analysed and functions should be analysed and allocated and then all output should be systhesized. In this process, the initial stakeholder？s requirements is represented to a few models and systemic performance requirements is developed. In this study, I exhibited how to develop the systemic performance requirements from the initial stakeholder？s requirement. Based on the results of this study, I will study on the adequacy of future and input-effcttiveness.
