# 10.8.1 Exercise: Choice of Appropriate Forecasting Techniques

### Intended learning outcomes: Propose a forecasting technique for different products to apply to forecast future demand.

Figure 10.8.1.1 shows historical demand curves for four different products. What forecasting technique for each product do you propose to apply to forecast future demand?

Fig. 10.8.1.1      Historical demand curves for four products.

Solution:
- Product 1: demand with linear trend —> linear regression
- Product2: constant demand without trend —> moving average forecasting or first-order exponential smoothing
- Product 3: seasonal fluctuations with trend —> linear regression or second-order exponential smoothing with seasonality
- Product 4: constant demand with seasonal fluctuation —> moving average forecasting, or first-order exponential smoothing, with seasonality
