Two types of robots (Cartesian and Articulated) with the following estimates are under consider­ation for a dishwasher assembly process. Using an interest rate of 10% per year, determine which one should be selected on the basis of an annual worth analysis.


AWCart = -300,000(A/P,10%,4) - 60,000 + 70,000(A/F,10%,4)
= -300,000(0.31547) - 60,000 + 70,000(0.21547)
= $-139,558

AWArt = -430,000(A/P,10%,6) - 40,000 + 95,000(A/F,10%,6)
= -430,000(0.22961) - 40,000 + 95,000(0.12961)
= $-126,420
