CASE STUDY PEFORMING ROR ANALYSIS FOR 3D PRINTER AND HOT TECHNOLOGY Background Software used in 3D printer systerns 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 it is being beta tested that will allow to type industrial Internet of Things connections between machines at distant locations. When onboard monitoring sensors detect that a part is about to fall, or it is time to replace one of several high-profile parts, the 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 IT 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 fight, underground in mines, on the ocean floor in war-tom areas, etc. Information For this case, we will analyre 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 technology in a wide variety of harsh environments-chemically toxic to humans, in flight, underground in mines, on the ocean floor, in w= Information For this case, we will analyze the available computers that can provide the server function necessary to make this interlinking available ar expected contribution to annual net cash flow, are summarized below. First cost, $ Server 1 100,000 Server 2 100,000 Net cash flow, $/year 35,000 25000 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 Life, years 3 4 Case Study Exercises Use spreadsheet analysis to determine the following: A-If the MARR = 12%, which server should be selected based on PW method to make the selection. (Hint: You have to use LCM for PW calcu Case Study Exercises Use spreadsheet analysis to determine the following: A-If the MARA = 12%, which server should be selected based on PW method to make the selection (Hint: You have to use LCM for PWcation) answer the below questions 1. The PW for server 13 years) LCM cash flow 2. The PW for server 24 years) LCM cash flow 3. The PW for server 35 years) LCM cash flow 4. Based on the PW analysis which option should be selected? 3- The ROR for each option, answer the below questions: 1. The ROR for servert over 3 years operation equal 2. The ROR for server2 over 4 years operation equal 3. The ROR for servers over 5 years operation equal 4. Based on the ROR for each option which option we should select? Use incremental ROR analysis between server 2 and server 3 to decide which is the best option at MARR - 12. Answer the below question 1. As per the Descartes rule of signs for the NCF between servers 283, what is the maximum number of real_number Delta that? 2. As per the Norstromecherion, is there a one real-positive Delta i existenter yes or no 3. What is the value of Detta between server 2 & 3 if exist? For Bank 10 4. Based on the incremental analysis which option we should select of incremental analysis is applicable
