An improved reliability prediction model based on BP network

Software reliability is a very important and active research field in software engineering. There have been one hundred of prediction model since the first prediction model published. Halstead model needn't test data and can be used before software test. But the model lost sight of many factors affecting software reliability. We aimed to improve prediction precision of Halstead model. So we improved the model which considered over software process factors affecting reliability and make use of BP network to calculate the weight.
