What production forecasting method would be used if an assumption was made that actual occurrences follow an identifiable pattern over time?

• A. Exponential smoothing
• B. Moving average
• C. Linear regression
• D. A and B

Answer: (D)

When actual occurrences show a recognizable pattern over time, forecasting relies on methods that extract and extend that pattern from historical data. Moving average does this by averaging a set number of recent periods, smoothing out random fluctuations so the underlying trend or pattern becomes clearer and can be projected forward. Exponential smoothing takes a similar idea but gives more weight to the most recent observations, allowing the forecast to adapt if the pattern is changing over time while still dampening noise. Because the assumption centers on a time-driven pattern, both approaches are appropriate tools. They provide simple, pragmatic ways to reveal and extend the pattern without requiring external predictors. Linear regression can model broad trends by using time as a predictor, but it isn’t a smoothing method that directly captures the pattern in the same way; in this context, the smoothing methods are the more direct fit, and using both offers complementary ways to detect and forecast the pattern.
