Question 3

The point has been reached where a biotechnology research and development company must expand by building a new facility. The search has been narrowed to four locations, all of which are acceptable to management. The assessment of these sites is being made on the basis of the six subjective location factors that follow. Management has agreed to use a five- point scale (Excellent = 5, Very good = 4, Good = 3, Fair = 2, Poor = 1) to quantify and compare their subjective opinions about the relative goodness of the sites). The weight reflects the importance of each factor in the decision. 
Factor Evaluation by Location $$\begin{array} { | l | l | l | l | l | l | } 
\hline \text { Location Factor } & \text { Weight } & \text { A } & \text { B } & & \text { D } \
\hline \text { Labor Climate } & 35 & \text { Exc. } & \text { Very Gd. } & \text { Very Gd. } & \text { Exc. } \

Question 5

A company desires to locate a new facility. Based on preliminary analysis, the choice has been reduced to four locations: A, B, C, and D. These four locations were rated on a scale from 1 (worst) to 10 (best) on each of four criteria. Each criterion was also weighted to indicate its importance (i.e., the higher the weight, the more important). The list of ratings and weights follows.
$$\begin{array}{l}
\text { Location }\
\begin{array} { | c | c | c | c | c | c | } 
\hline \text { Factor } & \text { Weight } & \text { A } & \text { B } & \text { C } & \text { D } \
