            FER  will  surely  be  a  great  assist  for  the  government  in  preparing  for  the
            instability of the exchange rate as such. Furthermore, as it’s a major player in
            forecasting of exchange rates, Bank Negara Malaysia (BNM) will also obtain
            the benefit of this research. In the near future, the use of forecasting exchange
            rates will surely be made better.
                Based on the prior study, a new FTS model was proposed by Yu (2005)
            during the creation of FTS model to modify the intervals length. As shown by
            the outcome, appropriate fuzzy relationships can be improved the forecasting
            values. Another study by Arumugam et al. (2013) was conducted in order to
            predict Taiwan export trade using FTS model and ARIMA model. The final
            results indicate that, FTS model beat ARIMA model with smallest average error
            and its ability to forecast the Taiwan export trade. A viable practice to forecast
            correctly and successfully future exchange were needed by the government
            in dealing with foreign exchange rate as it can affect the country currency.
            Even  though  lots  of  forecasting  method  were  used  to  predict  the  foreign
            exchange  rate,  still  there  are  no  way  to  show which  are  the  most  reliable
            forecasting  method.  As  stated  by  Applanaidu  et  al.  (2011),  the  selection
            methods should take into account several aspects, such as statistical data,
            financing, level of accuracy and its significance. Nonetheless, these models are
            quite expensive, need a great degree of expertise and numerous types of data
            which may not always be obtainable.
                Fuzzy rule-based systems (FRBS) deliver impulsive technique of reasoning
            based on linguistic models (Dubois and Prade, 2001). Often reasoning based
            on fuzzy models contribute an option to handle all kinds of unspecific data,
            which presented the way people think and make decisions.  (Rasmani and
            Shen, 2006). In fuzzy forecasting, the determination of fuzzy rules is one of the
            aspect  to  reflect  on.  The  FTS  rises  the  precision  of  the  results  made  in
            predicting  situations  that  involve  subjective,  ambiguous  and  inaccurate
            information by implementing these rules. So, in conjunction with this research,
            Weighted  Subsethood-Based  Algorithm  (WSBA)  is  suitable  for  generating
            fuzzy rules for two reasons, which are easiness of the method and possible to
            produce  higher  degree  of  accuracy  indirectly  minimize  rules  compared  to
            other methods (Chen and Tsai, 2008). The development of WSBA includes a
            modification of the Subsethood-Based Algorithm (SBA) and the use of fuzzy
            general rules and SBA values as weight.

            2.  Methodology
               This section explained and discussed in detail four parts that have been
            carried out in the research. The detailed are as follows.
            A.  Part 1: Compilation and Processing Data
                    Foreign Exchange Rate (FER) data is collected by referring to the to the
               secondary data of monthly FER for five years’ data from year 2010 to 2015.

                                                                80 | I S I   W S C   2 0 1 9
