Transcribed Image Text:PEFORMING ROR ANALYSIS FOR 3D PRINTER AND I1OT TECHNOLOGY Background Software used in 3D printer systems manufactured by Spectrum LASER Corp. is currently able to automatically develop hollows, shells, and "tree supports to save development time. Network printing for use on multiple machines and at different locations globally is available. New software, called JIT II, is being beta tested that will allow lloT-type (Industrial Internet of Things) connections between machines at distant locations. When onb oard monitoring sensors 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 toxic 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 interlinking available and successful. The first cost and other parameter estimates, including expected contribution to annual net cash flow, are summarized below. First cost, $ Net cash flow, $/year Life, years Server 1 100,000 35,000 3 Server 2 100,000 25000 4 Case Study Exercises Use spreadsheet analysis to determine the following: B- The ROR for each option, answer the below questions: 1. The ROR for server1 over 3 years operation equal - 2. The ROR for server2 over 4 years operation equal - 3. The ROR for server3 over 5 years operation equal - 4. Based on the ROR for each option which option we should select? Server 3 150000 50,000 year 1, plus 5000 per year for years 2, 3, and 4 (gradient) 70,000 maximum for years 5 on, even if the server is replaced 5
