IMSE 2710: Engineering Economic Analysis 3. A high-speed electronic assembly machine was purchased two years ago for $50,000. At the present time, it can be sold for $25,000 and replaced by a newer model having a purchase price of $42,500; or it can be kept in service for a maximum of one more year. The new assembly machine, if purchased, has a useful life of not more than two years. The projected resale values and operating and maintenance costs for the challenger and the defender are shown in the accompanying table on a year- by-year basis. If the before-tax MARR is 15%, when should the old assembly machine be replaced? Use the following data table for your analysis. Year Challenger Market O&M Value Costs 0 $42,500 1 Defender Market O&M Value Costs $25,000 1 31,000 $10,000 17,000 $14,000 2 25,000 12,500

Economics A commercial 3D printer is purchased for $310,000. The salvage value of the printer decreases by 45% each year that it is held. The cost to operate and maintain the machine the first year it is used is $12,000; these costs increase by $5,500 each year. What is the optimal replacement interval and minimum EUAC for the printer, assuming a MARR of 11% is used?   ORI:   years EUAC*: $

New-Project Analysis The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $830,000, and it would cost another $22,500 to install it. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $485,000. The MACRS rates for the first three years are 0.3333, 0.4445, and 0.1481. The machine would require an increase in net working capital (inventory) of $17,500. The sprayer would not change revenues, but it is expected to save the firm $351,000 per year in before-tax operating costs, mainly labor. Campbell's marginal tax rate is 25%.

The Delta firm intends to buy a device called machine X. Machine X would cost $25,000 and have little salvage value after 10 years of use. The machine is anticipated to bring around $10,000 annually. Do the simple payback period calculation.
