Forecasting Forecasting is important relative to capacity requirements planning. What are some of the merits of using judgment methods (i.e., qualitative data) in contrast to quantitative forecasting methods. Which methods are considered to be superior or more accurate, and in what forecast situations would require judgment methods? In what situations would require a quantitative approach to forecasting?

Using the accompanying log-log graph, answer the following questions: What are the implications for management if it has forecast its cost on the optimum line? What could be causing the fluctuations above the optimum line? If management forecast the tenth unit on the optimum line, what was that forecast in hours?

Suppose a four period weighted average is being used to forecast demand. Weights for the periods are: Wt-4 = 0.1 Wt-3 = 0.2 Wt-2 = 0.3 Wt-1 0.4 Demand observed in the previous four periods was: At-4 = 325 At-3 = 361 At-2 = 478 At-1 = 400 What will be the demand forecast for period t? (Keep one decimal place in your answer).

Forecasting at Hard Rock Cafe Watch: Forecasting at Hard Rock Cafe # Foresting With the growth of Hard Rock Cafe-from one pub in London in 1971 to more than 185 restaurants in 74 countries today -came a corporatewide demand for better forecasting. Hard Rock uses long-range forecasting in setting a capacity plan and intermediate-term forecasting for locking in contracts for leather goods (used in jackets) and for such food items as beef, chicken, and pork. Its short-term sales forecasts are conducted each month, by cafe, and then aggregated for a headquarters view. The heart of the sales forecasting system is the point-of-sale (POS) system, which, in effect, captures transaction data on nearly every person who walks through a cafe's door. The sale of each entrée represents one customer; the entrée sales data are transmitted daily to the Orlando corporate headquarters' database. There, the financial team, headed by Todd Lindsey, begins the forecast process. Lindsey forecasts monthly…
