Reliability in City Transport Vehicles, Equipment Lifetime and Security 700384

This paper deals with the statistical study carried out on brake, steering, and engine failures during the life-time of a 210-bus fleet. By the actuarial method and the corresponding distributions (almost all of them Weibull type exponential) schedules on recorded reliabilities, are deduced for the original parts supplied by the manufacturers, and also vehicle reliabilities when failing parts are replaced. We believe these reliability schedules may be useful when establishing future reliability contracts (non-existent up to now) for the acquisition of city transport vehicles from the viewpoint of security.
