1. Should a firm attempt to have fewer or more suppliers? What are the
advantages and disadvantages of each approach? Your initial post should
be 200-250 words.
2. Read Problem 6 in Chapter 6 of your textbook. Calculate and answer
parts a through d. Include all calculations and spreadsheets in your
post. Explain why the moving average method was used instead of another
forecasting method. What might be another forecasting method that could
prove to be just as useful? Your initial post should be 200-250 words.
The figures below indicate the number of mergers that took place in the savings and loan industry over a 12-year period.
| Year | Mergers | Year | Mergers |
| 2000 | 46 | 2006 | 83 |
| 2001 | 46 | 2007 | 123 |
| 2002 | 62 | 2008 | 97 |
| 2003 | 45 | 2009 | 186 |
| 2004 | 64 | 2010 | 225 |
| 2005 | 61 | 2011 | 240 |
- (a) Calculate a 5-year moving average to forecast the number of mergers for 2012.
- (b) Use the moving average technique to determine the forecast for 2005 to 2011. Calculate measurement error using MSE and MAD.
- (c) Calculate a 5-year weighted moving average to forecast the number of mergers for 2012. Use weights of 0.10, 0.15, 0.20, 0.25, and 0.30, with the most recent year weighted being the largest.
- (d) Use regression analysis to forecast the number of mergers in 2012.
Be sure each answer is 200-250 words. Problem 2 NEEDS to have calculations shown. I will be submitting responses to turn it in.com. If your response shows up as plagiarized I will not be paying.
