A QoS-based fuzzy model for evaluation service quality parameters in service-oriented architecture

Nowadays, service-oriented architecture is developed as a flexible architecture for developing dynamic systems. In consider to the importance of quality of service (QoS), measured parameters in this architectural services such as security, reliability and ... has a special place. Uncertainty of parameters affect service quality is considered as a key challenge in such environments. This requiring measurement of these parameters reveals a consistent and efficient manner. Since fuzzy logic is able to express the relative value of the credit in real-world concepts, this article proposes an approach on fuzzy logic to deal with these challenges and evaluation of quality of service.
