Consider a company that manufactures three home air conditioners: an economy model (E), a standard model (S), and a deluxe model (D). The objective is to determine how many economic models, standard models, and deluxe models they should produce in order to maximize profit. Each model requires processing time (seconds) at three workstations detailed below. Product D 4 seconds Product E Product S Process time at workstation 1 Process time at workstation 2 Process time at workstation 3 3 seconds 5 seconds 5 seconds 3 seconds 4 seconds 2 seconds 4 seconds 7 seconds Profit per unit 63.00 $ 95.00 S 135.00 The goal of maximizing profit is analyzed over a one-hour period (3,600 seconds). Using Excel Solver, the folowing sensitivity report was generated.
