  • Abstract:
    Several industries now use risk analysis to develop ; inspection programs to ensure acceptable mechanical integrity ; and reliability. These industries include nuclear and electric ; power generation, oil refining, gas processing, onshore and ; offshore exploration and production, chemical processing, and ; pipelines. Risk analysis may also be used as a decisionmaking ; tool in the railroad industry to develop systematic ; improvements in track maintenance and inspection strategies. ; In the course of conducting research in support of the ; Federal Railroad Administration, a Monte Carlo risk ; assessment model has been developed to simulate certain ; aspects of rail inspection (also referred to as rail testing) to ; find and remove defects that may grow to sufficient size to ; cause rail failures. In this paper, the model is used to examine ; the relationship between the occurrence of rail failures and ; various operational factors. These operational factors include ; rail size, average axle loading, and inspection frequency. In ; addition, the risk assessment model is used to evaluate an ; alternative rail testing concept in which detector cars would ; conduct inspections at speeds higher than those used in ; current practice.
