Equipment replacement and optimal size of a civil engineering fleet

This paper analyses the optimal heavy civil engineering equipment fleet size. The study was initiated by a military unit, which has a fleet of a few hundred pieces of equipment. Prior to the study only operative considerations dictated fleet size and replacement policy. An economic analysis on the individual piece of equipment level is presented, as well as the collection of data for it. The main recommendations for the first year were to sell 33% of the existing fleet and buy new equipment at the rate of 10% of the existing fleet.
