DESICION SUPPORT SYSTEM USING TOPSIS METHOD FOR SMARTPHONE SELECTION
Keywords:
TOPSIS, positive ideal distance solution, negative ideal distance solution weighted normalized decision matrixAbstract
Nowadays smartphone has developed rapidly, within days and months, they will build many smartphones and with so many differences feature such as more powerful processors, wider screen, more powerful front and back camera etc. Sometimes buyer has difficulties in determining which smartphone that most suitable with their needs. In this research, we implement TOPSIS method to support buyer in choosing the most appropriate smartphone, based on its feature and brands. TOPSIS, stand for Technique for Order of Preference by Similarity to Ideal Solution, is one of Decision support method based on calculation of positive ideal distance solution and negative ideal distance solution. Final output of TOPSIS calculation is order of priority of recommended smartphone’s brand. TOPSIS was also applied in Decision Support System, where the output of this application was compared with the result of manual TOPSIS calculation.
