The relationship between object oriented metrics and software maintainability is complex and ***,there is considerable research interest in development and application of sophisticated techniques which can be used to build models for predicting software ***,when predicting maintainability not only product quality measurements are surrounded with imprecision and uncertainty,but also the relationships between the external and internal quality attributes suffer from imprecision and *** reason behind that,there are at least two important sources of information for building the prediction model: historical data and human ***,in this paper an attempt has been made to utilize the capability of fuzzy logic in handling imprecision and uncertainty to come up with an efficient maintainability prediction *** proposed model is constructed using object-oriented metrics data in Li and Henry's datasets collected from two different object-oriented systems.
