Availability and Work Targets of Bulldozers

Setting work targets for machines is an important task for engineering managers, especially where they operate large fleets with machines of different makes and ages. Setting uniform work targets is easier but it does not take into account operating characteristics of machines which could differ with make and change with age. It is suggested here that using analysis of availability of machines can provide an alternate basis to set work targets. Availability analysis of bulldozers is reported here which suggests the feasibility of achieving higher work targets compared to the present 1000 hours per season.
