Wykorzystanie modeli wyrównywania wykładniczego w prognozowaniu zmiennych o wysokiej częstotliwości w warunkach braku pełnej informacji

Abstract: Streszczenie: W pracy przedstawione zostaną wyniki wykorzystanie modeli wyrównywania wykładniczego (Browna, Holta i Holta-Wintersa) w postaci addytywnej i multiplikatywnej w prognozowaniu interpolacyjnym i ekstrapolacyjnym zapotrzebowania na moc energetyczną w okresach godzinnych w aglomeracji A na podstawie szeregu z lukami systematycznymi. Podstawą budowy prognoz będą szeregi czasowe, z których wyeliminowano wahania o cyklach: dwunastomiesięcznym, tygodniowym lub także dwudziestoczterogodzinnym. Przeprowadzo… Show more

“…The benefit of these models is that they give the models under investigation a considerable deal of flexibility; nevertheless, the drawback is that they demand more advanced research skills from the researcher than, for instance, the regression analysis [34]. The linearity of the ARIMA model is another drawback [20].…”

“…The aforementioned information leads to the conclusion that not all procedures utilized in the situation under review are successful. To determine the best forecasting method, the value of mean absolute percentage error MAPE (20) was used for which the analyzed value was the smallest. The best forecasting techniques for each road were determined to be the following:…”
