ESSAY/SHORT ANSWER QUESTIONS (35 possible points)Please answer each of the following questions. 1. INTRODUCTION(10 Possible Points) Explain the difference between quantitative and qualitative analysis from the manager s point of view. 2. DECISION ANALYSIS (10 possible points) Give an example from your own work experience, or make up an example, of how Decision Analysis could be used to determine an optimal strategy. Briefly describe several decision alternatives you, as the decision maker, would be faced with and possible uncertain or risk-filled future events you would need to consider. 3. FORECASTING (15 possible points) A. What is the difference between Quantitative forecasting methods and Qualitative forecasting methods? B. Under what circumstances would it be more appropriate to use quantitative rather than qualitative forecasting methods? BSC400 MIDTERM EXAMPage 4 3. FORECASTING (Cont.) C. Give an example of a situation when using quantitative forecasting would be appropriate. SECTION IV: PROBLEMS (45 possible points) PROBLEM 1: LINEAR PROGRAMMING MODEL DEVELOPMENT (20 possible points)A manufacturer makes two products, doors and windows. Each must be processed through two work areas. Work area #1 has 60 hours of available production time. Work area #2 has 48 hours of available production time. Manufacturing of a door requires 4 hours in work area #1 and 2 hours in work area #2. Manufacturing of a window requires 2 hours in work area #1 and 4 hours in work area #2. Profit is $8 per door and $6 per window. As you respond to the following questions, please note that you are only setting the problem up. A solution to determine the number of doors and windows to be manufactured and the resulting profit is NOT necessary.1. Define the decision variables that will tell how many units to build (doors and windows). 2. Develop an objective function that will maximize profits. 3. Develop production constraints for work areas #1 and #2.

What decision should be made by an optimist? 2. What decision should be made by a conservative? 3. What decision should be made by using minimax regret? 4. Unrelated to this problem, which approach do you personally prefer optimistic, conservative, or minimax regret Explain.
