Nano Technologies intends to use the newest and finest equipment in its labs. Accordingly, a senior engineer has recommended that a 2-year-old piece of precision measurement equipment be replaced immediately. This engineer believes it can be shown that the proposed equipment is economi- cally advantageous at a 10% per year return and a planning horizon of 3 years. (a) Perform the replacement analysis using the annual worth method for a specified 3-year study period. (bj Determine the challenger's capital recovery amount for the 3-year study period and the expected full life. Comment on the effect made by the 3-year study period. Current Proposed Original purchase price, 5 OD'DE- Current market value, $ 17,DO0 Remaining life, years S 15 wimated value in 3 years, $ 9000 20 00 salvage value atber 15 years, $ 5.000 Annual operating cost, $ per year -8.000 -3,000We continue with the progressive example of possibly replacing a kiln at B&T Enterprises. A marketing study revealed that the improving business activity on the west coast implies that the revenue profile between the installed kiln (PT) and the proposed new one (GH) would be the same, with the new kiln possibly bringing in new revenue within the next couple of years. The president of B&T decided it was time to do a replacement study. Assume you are the lead engineer and that you previously completed the ESL analysis on the challenger (Exam- ple 11 3) It indicates that for the GH system the ESL is its expected useful life. Challenger: ESLA = 12 years with total equivalent annual cost AW= $-12.32 million The president asked you to complete the replacement study, stipulating that, due to the rapidly rising annual operating costs (AOC), the defender would be retained a maximum of 6 years. You are expected to make the necessary estimates for the defender (PT) and perform the study at a 15%% per year retum.\f\f\f
