Framework for Aggregating Interactive Multi-Criteria for Web-Based Applications Using Fuzzy Measure and 2-Additive Choquet Integral

Web-based Application (WBA) quality is hard to evaluate because it consists of multiple criteria to be measured. Researchers have developed software quality models that were intended to be comprehensive and applicable to all software development. However, most of the works that focus on the quality...
