The vehicle replacement decision is a multi-objective optimization problem subject to the acquisition budget and government regulation constraints. This necessitates a condition-based replacement policy. In this paper, we carry out a case study of the vehicle fleet replacement problem. Based on the field data in a vehicle fleet management system, we derive a set of condition parameters for representing the health level of a vehicle. A correlation analysis is carried out to identify key condition parameters. The identified parameters are then combined into a health index. The index is useful for condition-based vehicle replacement decision.
