Evaluation of overhaul/replacement policy for a fleet of buses Available to Purchase

Presents a case study on overhaul/replacement policy for a fleet of buses owned by a Saudi Arabian transport company. Data on overhaul and operational costs for two types of bus engines have been collected and analysed by standard statistical procedures to establish their functional characteristics and also age dependency of the overhaul costs. Evaluates two major decisions involving overhaul cost limit and number and timings of overhauls. The analysis shows that the existing overhaul policy is similar to the analytically obtained policy.
