Medco plans to open a new medical center and is looking for a suitable location. They
have narrowed their choice down to three locations, on Oak, Elm, and Ash Streets. They
have defined four factors and have assigned weights to these factors as follows:
proximity to hospitals (40), customer parking (30), appearance (20), and ease of
expansion (10). They then rated the three locations for the four factors, using a scale of
one to five. Their ratings are as follows:
(a) Calculate the scores for each location.
(b) According to the model which location should they choose?

model.
c) Both models use the same formula to compute annual ordering cost.
