A performance-based approach for assessing the quality of group buying websites

Abstract

This research work demonstrates a performance-based approach to evaluate the quality performance of group buying websites under uncertainty. Linguistic variables are assigned with values using triangular fuzzy numbers approach for effectively modeling the vagueness and imprecision of the decision making process. An effective algorithm grounded on the deviation degree and absolute area of a fuzzy number is developed for generating a general performance index for each alternative. This would help companies understand the performance quality level of their group buying websites. A group buying website quality performance evaluation example demonstrates how performance based approach can be used to assess the quality.
