2. SHAS Bhd. is considering expanding its range of industrial machinery products by manufacturing machine tables, saddles, machine bases, and other similar parts. Several combinations of new equipment and personnel could serve to fulfill this new function: Method 1 (M1): new machining center with three operators. Method 2 (M2): new machining center with an automatic pallet changer and three operators. Method 3 (M3): new machining center with an automatic pallet changer and two task-sharing operators. Each of these arrangements incurs different costs and revenues. The time taken to load and unload parts is reduced in the pallet-changer cases. Certainly, it costs more to acquire, install, and tool-fit a pallet changer, but because the device is more efficient and versatile, it can generate larger annual revenues. Although saving on labor costs, task-sharing operators take longer to train and are more inefficient initially. As the operators become more experienced at their tasks and get used to collaborating with each other, it is expected that the annual benefits will increase by 13% per year over the five-year study period. SHAS Bhd. has estimated the investment costs and additional revenues as follows: Machining Center Methods MI (RM) M2 (RM) M3 (RM) 121 000 121 000 66 600 Investment: Machine tool purchase Automatic pallet changer Installation Tooling expense Total investment 30 000 58 000 42 000 65 000 294 600 121 000 66 600 42 000 65 000 294 600 209 000 55 000 69 300 36 000 Annual benefits: Year 1 Additional revenues Direct labor savings Setup savings Year 1: Net revenues Year 2-5: Net revenues Salvage value in year 5 55 000 constant 80 000 4 700 74 000 constant 17 300 4 700 58 000 g=13%/year 120 000 120 000 All cash flows include all tax effects. "Do nothing" is obviously an option, since SHAS Bhd. will not undertake this expansion if none of the proposed methods is economically viable. If a method is chosen, SHAS Bhd. expects to operate the machining center over the next five years. On the basis of the use of the PW measure at i = 12%, which option would be selected
