1. Describe some quantitative and qualitative forecasting techniques.
2. Compute a three-week moving average forecast for the arrival (incoming) of a particular strategic item in week 4. The number of arrivals for the past 3 weeks were:

Week	Item Arrival (incoming)
1	411
2	380
3	421

If the actual number of items arrival in week 4 is 426, what is the forecast error for week 4? What is the forecast for week 5?

If the smoothing parameter = 0.10, and it is end of week 3, calculate the exponential smoothing forecast for week 4.

2. What is the difference between pure and mixed strategies in production planning?
3. Explain the terms:
4. Collaborative planning, forecasting and replenishment (CPFR)
5. Mean Absolute Percentage Error (MAPE)
6. Batch Processes
7. Economies of Scale
8. Just-in-time Production
