Question
Chapter 4.12, Problem 7P
To determine
The objective tree for the following statement: We have a mountain-sized pile of wood chips that we want to process into the fire logs for home use. We are located in Tallahassee, Florida. We can have a continuous supply of wood chips throughout the year. We should be able to produce 50 fire logs per minute. The shareholders require us to have a large profit margin, and our price should be lower than our competition for the same size logs. The logs should produce enough heat to keep our customers satisfied, and they should have environmentally clean exhaust.
