The demand for quality software system is increasing day by day because quality defines the capability of the software systems. Software systems are root of any developing systems. They are always checked on the basis of their quality. The quality characteristics are considered as very important aspects by development of software system. The evaluation of quality also plays important role in this context. Fuzzy logic is the new emerging technology for evaluating the efficiency of various systems. This paper presents various quality models and evaluation of quality models by using fuzzy logic technique. The present study may serve the purpose of reference for investigating evaluation of software quality models with their analytical description.
