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 1,750 hours per year.
Machine availability 75% for Machine D1 and 70% for Machine D2. The yield of D1 is 90%, and the yield of D2 is 80%. Annual operating expenses are based on an assumed operation of 1,750 hours per year, and workers are paid during any idle time of Machine D1 or
Machine D2. Assume repeatability.
