For some years, the City of Armstrong Power Authority has used 4-20 mA technology to measure parameters such as pressure, temperature, flow rates, and speed of various machinery and systems installed in its generation facilities. It now plans to use the same technology to measure vibration on all of its rotating machinery with the goal of evaluating continuously the health of the equipment, to include friction buildup, breakdown prediction, and preventive maintenance needs. Depending upon the vendors chosen, the useful lives and anticipated annual net savings will vary, as reflected in the estimates shown.
Use repeated spreadsheet solutions of the capital budgeting problem with investment limits ranging from $0.5 million to $2.5 million (in $0.25 million increments, i.e., $250 increments since all estimated values are in $1000 units) to determine the best selections. Once done, develop a graph that plots the investment limit versus the value of Z. Use MARR = 5% per year.
