| Abstract | ||
| This paper deals with evaluating the performance of method (Holt-Winter) in the development of forecasts for periods 1,2,3,4,5,6. Future parameters of optimal and non-optimal pave compared with Holt-Winter Road) (normal (classic) known constants optimal and non-optimal and also in the case of time-series of seasonal nonstationary any that occur in the pattern of permanent changes temporary or infrastructure to ask him to use the style simulation Toledhzh chains In addition to preparing special programs in a way (Holt-Winter) adaptive and normal language (Quick Basic). Has been reached that the way adaptive placed Find her a slight advantage on the way normal in the development of forecasts for a period of one (L = 1) that the performance of the two methods symmetric in the development of Altenbaat6-2 future periods, and so for the time series of seasonal stationary parameters of optimal boot, either Balnsphllslasl Time Seasonal nonstationary way, the performance of the adaptive parameters of optimal and non-optimal ahead significantly in the development of forecasts (6-1) periods, compared with the usual way. | ||
