CASE STUDY -- STRENLAR A report submitted for the student project under the course SEEM 5820/ECLT5920 ABSTRACT Life is full of hard decisions which always make people scratch their heads. In this case study—Strenlar, Fred Wallace is faced with some alternatives which are difficult for him to choose. Our task is helping Fred to make it easier for him to make a decision. By using the theory and methodologies introduced in the textbook, Making Hard Decisions, and some software, we will structure the problem, model Fred’s decisions, use three set of data to test Fred’s decision model, carry out a sensitivity analysis on different variables as well as risk tolerance, and refine the model. At last, we conclude some advice for Fred to make a decision.
