Three large industrial centrifuge designs are being considered for a new chemical plant. By using the data in the table below, recommend a preferred design with each method that was discussed in this chapter for dealing with non-monetary attributes. Assume that knowing the safety value is better than any unknown value.
a. Which alternative would be selected based on Non-dimensional scaling method? [Choose]
- Design A
- No alternatives
- Design C
- Design B
b. Which alternative would be selected based on Additive Weighting (using given weights) method? [Choose]
- Design A
- No alternatives
- Design C
- Design B
