Usability Evaluation of Software Systems using Fuzzy Multi- Criteria Approach

Over the past few decades, Usability has emerged as an extremely important quality factor. Many methods have so far been proposed for usability evaluation but they lack in one way or another. This paper proposes a method for software usability quantification using the fuzzy multiple criteria weighted average approach. This approach has been chosen due to the highly unpredictable nature of the attributes on which usability depends. A case study is presented to prove the feasibility of the quantification technique.
