SYSTEM EFFECTIVENESS STUDIES

The report describes an investigation of the feasibility and appropriateness of system effectiveness techniques in the analysis and design of high speed ground transportation systems. A computerized model was constructed which employs selectable reliability and failure distributions to interrelate the performance of an HSGT system in terms of adherence to established schedule and the various reliability and failure parameters on the subsystem and component level. The model is based upon an analytic combination of the conditional reliability and failure distribution. Three train failure modes, distinguished by the limiting speed encountered for the various component failure contributions, are considered. These lead to the overall probability of reduced operating performance for a train and, finally, to the probability distribution of delays in a network. The computer output information is prepared so as to be compatible input to a TRANSIM simulation program developed under an associated system engineering support task. (Author)
