Abstract

To forecast the non-stationary data is quite di±cult when compared with the stationary data time series. Because their variances are not constant and not stable like the second data type. This paper presents the implementation of fuzzy time series (FTS) into the non-stationary time series data forecasting, such as, the electricity load demand, the exchange rates, the enrollment university and others. These data forecasts are derived by implementing of the weightage and linguistic out-sample methods. The result shows that the FTS can be applied in improving the accuracy and e±ciency of these non-stationary data forecasting opportunities. Keywords: Fuzzy time series; non-stationary data; electricity load; exchange rates; enrollment
