A machine has three components with different failure rates.
The economic life of the machine is 10,000 hours and its unit cost is $3000.
For each component, the variable labor cost per hour for repair is $80 and the
variable labor cost per hour for replacement is $60. The fixed cost for repair
is Cf and the fixed cost for replacement is the unit cost Cu. Given the
following data, determine whether to repair or replace each component upon
failure and estimate the life cycle cost of the machine relative to the data
given
