11. A major consumer products company is determining the value of its program which includes two projects, A and B. There are three technologies that are affected: 1, 2, and 3. Project A has a major contribution to technology I, no contribution to technology 2, and a major contribution to technology 3. Project B has no contribution to technology I and a minor contribution to technologies 2 and 3. There are two requirements, a and 6, that are affected by these three technologies. Requirement a has a relative value of 0.6 and requirement b of 0.4. Technology 1 makes a contribution to requirement a but not to b. Technology 2 makes no contribution to requirement a but does to requirement b. Technology 3 makes a contribution to both requirements a and b. What is the overall value of this company's program?

12. Nina is trying to decide in which of four shopping centers to locate her new boutique. Some cater to a higher class of clientele than others, some are in an indoor mall, some have a much greater volume than others, and, of course, rent varies considerably. Because of the nature of her store, she has decided that the class of clientele is the most important consideration. Following this, however, she must pay attention to her expenses and rent is a major item, probably 90 percent as important as clientele. An indoor, temperature-controlled mall is a big help, however, for stores such as hers where 70 percent of sales are from passersby slowly strolling and window shopping. Thus, she rates this as about 95 percent as important as rent. Last, a higher volume of shoppers means more potential sales; she thus rates this factor as 80 percent as important as rent.

As an aid in visualizing her location alternatives, she has constructed the following table. A "good" is scored as 3, "fair" as 2, and "poor" as 1. Use a weighted score model to help Nina come to a decision.
