Abstract
The purpose of this report is to identify the optimal replacement strategy for the Canadian Forces (CF) Long-Range Patrol CP-140 fleet. The adopted mathematical formulation is a fusion between an intergenerational model and an approach which uses the notion of operational availability of aircraft. In this resulting model, operating and maintenance costs per available year are estimated as a function of aircraft age during its life cycle. After determining the optimal age of replacement, a sensitivity analysis was carried out to assess the impact of some key model parameters on the result. This repair or replace model has the huge advantage of being applicable to any kind of heavy equipment. For example, it may be used to determine, in the same manner, the optimal age of replacing several types of fleets such as helicopters, ships, tanks, trucks, etc.
