4-1. Provide an example based on your professional experience of a situation in which using a multiple regression model or nonlinear regression model may have helped your organization make a better decision.
4-2. What types of business situations or problems might best lend themselves to multiple linear regression? What types may not? When do you anticipate using a multiple linear regression model in your postgraduate, professional experience? Explain.
5-1. Discuss the strategic importance of forecasting at your organization (or one with which you are familiar). What strategic decisions does it need to make in terms of forecasting? Provide two recent examples. In your opinion, was this the best way? How could the process be improved?
5-2. Refer to the Topic Material, “Chapter 1 – Fundamental Issues in Business Forecasting.” This resource includes a discussion of unrealistic expectations and forecast accuracy. How have you seen this demonstrated in your organization or industry? Describe the forecasting scenario and the “prediction” that did not come true. What conversations did management have surrounding this issue? How would you mitigate expectations for a situation like this in the future?
6-1. Identify two key strategic decisions made by your current team, department, or organization. How could those decisions have been enhanced by optimization models? Support your rationale with evidence from readings or external research.
6-2. Find a current example of a linear optimization model used in your industry. Describe the industry’s needs, including any unique factors, how the linear optimization model was used, and the problem or challenge it addressed. Would you suggest a different model be used? Why or why not? Support your response with rationale from the assigned readings.
7-1. Explain the importance of correctly stating the objective function and constraints in linear optimization problems. Using examples from your professional experience, describe the problems that could result if the objective function and constraints are not stated properly. Why did these problems arise? Support your anecdotal evidence with support and rationale from the readings.
7-2. Describe a workforce scheduling, a blending, and a logistics problem facing your current organization or industry. What is being optimized in each of your examples and why? How do linear optimization techniques differ from decision tree analysis? Which are more applicable to the examples you identified? Support your response with rationale from the readings.
8-1. Describe a current problem facing your department, organization, or industry that would indicate the need for simulation. What key factors of this business situation indicate the need for simulation (versus the other modeling techniques covered in the course)? Support your response with rationale from the readings.
8-2. Consider some of the examples you have brought up in earlier topics. Describe the key differences between simulation models and the models covered earlier in the course. Outline how the approach to solving this problem would differ in terms of applying and computing/solving the models.
