Based on the maintenance data of open pit haulage machines, dump trucks and tire shovels, an optimumoperation planning for these machines was discussed.
Considering the total investment of machine consists of the machine value purchased, overhaul cost andmaintenance cost, Total investment=machine value purchased+overhaul cost+maintenance cost was formulated as the fundamental equation.
Then, the analysis of these costs were performed and simulations were carried out by introducing aninflation effect and D. C. F. concept. And conclusively, optimum replacement time of machine to new machine was decided and abenefit of employment of larger size machines was discussed.
