Question
A new manufacturing facility will produce two products, each of which requires a drilling operation during processing.
Two alternative types of drilling machines (D1 and D2) are being considered for purchase. One of these machines must
be selected. For the same annual demand, the annual production requirements (machine hours) and the annual
operating expenses (per machine) are listed in the table below. Which machine should be selected if the MARR is 12%
per year? Assumptions: The facility will operate 2,250 hours per year. Machine availability is 85% for Machine D1 and
80% for Machine D2. The yield of D1 is 85%, and the yield of D2 is 75%. Annual operating expenses are based on an
assumed operation of 2,250 hours per year, and workers are paid during any idle time of Machine D1 or Machine D2.
Assume repeatability.
