Summary form only given. Forecasting is the statement about the unknown results or outputs of events that will occur at a specific time in the future. To enhance the organizational competitive advantage in a constantly fluctuating environment, an organization's management must make the correct decision on a timely basis depending on the information available.

Using sixty periods of simulated data for each time series, forecasts were prepared for the next thirteen periods.
