CASE STUDY PEFORMING ROR ANALYSIS FOR 3D PRINTER AND IIOT TECHNOLOGY Background Software used in 3D printer systems manufactured by Spectrum LASER Corp. is currently able to automatically develop hollow, shells, and tree support to save development time. Network printing for use on multiple machines and at different locations globally is available. New software, called JET IT, is being beta tested that will allow IIoT-type (Industrial Internet of Things) connections between machines at distant locations. When onboard monitoring sensor detect that a part is about to fail, or it is time to replace one of several high-profile parts, the JIT Il software will automatically queue the part's manufacturing code onto a 3D printer that is detected to be locally idle or ready. The company believes it can design and produce the JIT Il software, the 3D printers, and the accompanying computer equipment necessary to place this technology in a wide variety of harsh environments-chemically torde to humans, in flight, underground in mines, on the ocean floor, in war-torn areas, etc. Information For this case, we will analyze the available computers that can provide the server function necessary to make this intertinking available and successful. The first cost and other parameter estimates, including expected contribution to annual met eash flow, are summarized below. Server 1 Server 2 First cost, 119.927 200,000 50,000 year 1. plus 5000 per year for years 2, 3, and 4 (gradient) Net cash flow, $year 35,000 70,000 maximum for years 5 on, even if the serveris replaced Life, years Server 1 Server 2 First cost, $ 119.927 200,000 Net cash flow, S/year 35,000 50,000 year 1. plus 5000 per year for years 2, 3, and 4 (gradient) 70,000 maximum for years Son, even if the server is replaced Life, years 3 5 Case Study Exercises Use spreadsheet analysis to determine the following: 1. Use incremental ROR analysis to decide between the servers at MARR = 18%. Note that you have to use LCM.
