PEFORMING ROR ANALYSIS FOR 3D PRINTER AND NOT TECHNOLOGY Background Software used in 3D printer systems manufactured by Spectrum LASER Corp. is currently able to automatically develop hollows, shes, and tree supports to development Network connections between machines at distant locations. When onboard monitoring sensors detect that a part is about to fit, or is time to replace one of several high profile parts, the l'il sottware printers, and the accompanying computer equipment necessary to place this technology in a wide variety of harsh environments-chemical toe totumas, net under pound in mines, on the ocean floor, in war-torn areas et Information For this case, we will analyze the available computers that can provide the server function necessary to make this interlinking wable and succesful. The first cost and other permeter estimates including expected contribution to annual net cash flow are summarted below. Server ! 100.000 cost, 100,000 150000 50,000 year 1. plus 5000 per year for years and Net cash flow. Saya 35.000 25000 70,000 maximum for years Son, even if the serveris replaced 5 fears 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, Ort: You have to use LCM for PW calculations awer the below questions 1. The PW for server 12 years) LCM cash flow 2. The PW for server 214 years) L.CM cash flow = 3. The PW for server 3 (5 years) LCM cash flow - 4. Based on the PW analysis which option should be selected? 8- The ROR for each option, answer the below questions 1. The ROR for servert over 3 years operation equal - 2. The ROR for server over 4 years operation equal 3. The ROR for server 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 questions 1. As per the Descartes rule of sigras for the NCF between servers 28.2, what is the maximum number of real number Deta_ ithat exist? 2. As per the Norstroms criterion, is there a one real-positive Delta i existenter yes or no? 3. What is the value of Delta" between server 2 & 3 if exist? 4. Based on the incremental analysis which option we should select if incremental analysis is applicable
