Disadvantages of Forecasting

Inaccurate Forecasts: Forecasts are not always accurate.
Unreliable Information: Forecasting methodologies can be unreliable.

Using Forecasting For 3 Period Weighted Moving Average

Calculate forecasting using a weighted average of the previous 3 periods with weights as follows:
- Period 1: 3
- Period 2: 2
- Period 3: 1
Use the following steps:
- First Year Calculation: (3 * Period 1 Demand) + (2 * Period 2 Demand) + (1 * Period 3 Demand) / (Total Weights)
- Second Year Calculation: (3 * Period 2 Demand) + (2 * Period 3 Demand) + (1 * Period 4 Demand) / (Total Weights)
- Continue the same pattern for subsequent years.

Using Exponential Smoothing for Forecasting

The formula for exponential smoothing is:
- Forecast for the next period = (Alpha * Actual demand for the previous period) + [(1 - Alpha) * Forecast for the previous period]
Use the following steps:
- Start with a forecast for the initial period (e.g. the first year).
- **Apply the formula to calculate subsequent forecasts. **
- The alpha factor represents the smoothing constant, which ranges between 0 and 1.
- Higher alpha values give more weight to recent data.

Using Moving Average for Forecasting

Calculates forecasts based on the average of recent demand data.
Types of moving average:
- 2-year moving average: Uses the average of the past two years' data.
- 5-year moving average: Uses the average of the past five years' data.
Use the following steps:
- **Start by calculating the average values for the defined period. **
- Calculate the forecast for the subsequent year using the average.
- Continue the same pattern.

Calculating Forecasting Error

Forecasting Error = (Actual Demand - Forecast)
Mean Squared Error (MSE):
- Calculate the squared difference between the actual demand and forecast.
- Sum the squared errors.
- Divide the sum by the number of periods.
