QUESTION 1 CASESTUDY PEFORMING ROR ANALYSIS FOR 3D ERINTER AND IOT TECHNOLOGY Background Sottware used in 3D printer systems manufactured by Spectrum LASER Corp. is currently able to automatically develop hollows, sheils, and tree supports" to sive deveicpment timie. Network printing for use on multiple machines and at different locutions globally is available. New sotware, caled jiff it, is being beta tested that will allow lilot. type findustrial internet of Thinge: connections between machines at distant locations. Whon onboard moniloring sensors detect that a part is about to fail or it is time to reploce one of several high-profile parts, the jif II software wifl ausomatcally queue the part's manufacturing code onto a 30 printer that is detected to be locally idle or ready. The company believes it can design and produce the jif Il software, the 30 printers, and the accomparying computer equipment necessary to place this technology in a wide variety of harsh environments-chemiculy toxic to humans, in flight, underground in mines, on the ocean foor, in war tom areas, etc. Information For this case, we will analye the available computers that can provide the sever function necessary to make this interinking available and successful. The first cost and other paraineter estiratas. including expected contribution to annual net cash flow, are summarized below. Case study fxercises Wie spreadsheet analysis to determine the following: A If the MARR - 124, which server should be selected based on PW method to make the selection, (fint : You have to use LCM for PW cabcuationb) avaser the below questions: 1.
