• Abstract:
  This report provides a systems approach to the assessment, evaluation and application of high-speed guided ground transportation (HSGGT) safety criteria and ; presents one potential methodology by combining a work breakdown structure (WBS) ; approach with an interface evaluation methodology. By systems approach i£ is meant ; that safety considerations and criteria are tied to an HSGGT structural concept and ; are addressed from the highest level of a system hierarchy downward in a WBS. Safety ; criteria can then be logically associated with each system structure. This is a ; departure from the traditional approach of assessing safety issues individually and in ; isolation of other factors. ; The generic work breakdown structure (WBS) developed by The Defense Systems ; Management College and outlined in its publication, System Engineering Management ; Guide, was selected to structure the ; complex configurations of a generic maglev system and a generic high speed rail (HSR) system. Both WBS provide a system approach to the assessment of the need for and application of safety regulations in the field of high-speed guided ground transportation (HSGGT). A typical generic WBS is composed of segments, elements, subsystems, and components, but the maglev and HSR WBS presented ; in this report are defined to the subsystem level only, allowing for further lower ; level definitions at a later time. ; Each WBS is organized on the basis of providing mutually exclusive segments on a technological basis at least to the maximum extent that is reasonable. A methodology known as n-1 is used to describe a means to create diagrams that depict the interface between segments, elements, and subsystems. A total of 129 subsystems are identified for a generic maglev system and 118 are identified for a generic HSR system.
