Comparison between smart phones on the basis of their reliability factors

These days smart phones has become very important part of our day to day life. So it is necessary that these smart phones should be more reliable. In this study, we are doing comparison between four smart phones of same company named Samsung on the basis of their reliability factors using Multi Criterion Decision Making (MCDM) Technique-Analytic Hierarchy Process (AHP). In first step we find out the reliability factors of the smart phones and then using AHP we find which reliability factor is most important criterion and which is least important criterion. Through this we find which is the best alternative among the given alternatives. Another method used in this study was a survey. A survey was conducted, in which questions on the basis of reliability of smart phones were asked. And then it was decided which smart phone is better.
