Forecasting with Weighted Fuzzy Time Series (WTFS) is a method that developing of Fuzzy Time Series (FTS) method. WFTS method is developing of FTS method, with added a step, that is weighting when calculate forecast. In this thesis used Cheng’s method for data analysis. Previously used Chen’s and Yu’s method for data analysis to get minimum MAPE, that used in Cheng’s method. The different from third algorithm is weighting and forecasting.
