Below are forecasting techniques often used in Operations Research.
For series without trend and seasonality.
Model:  where:
 is independent and 
Moving Average

Where




= an estimate of M made at time t


N
= observations (given equal weight)



= new observation



Single Exponential Smoothing
Include all past data and give greater weight to more recent observations.


Where St = exponentially smoothed average at time [...]<p><a href="http://math-help.info/2009/05/forecasting-techniques/">Forecasting Techniques</a> is a post from: <a href="http://math-help.info">Math Help</a></p>
