Abstract
Software reliability is generally a key factor in software quality. Reliability is an essential ingredient in customer satisfaction. In software development process reliability conveys the information to managers to access the testing effort and time at which software release into the market. Large numbers of papers are published in this context. In this paper we proposed a software reliability growth model with generalized modified weibull testing effort. Performance application of proposed model is demonstrated through real datasets. The experimental results shown that the model gives an excellent performance compared to other models. We also discuss the optimal release time based on reliability requirement and cost criteria.

Reliability is one of the key factors in accessing the quality of the software
Software reliability is defined as probability of failure free software over a period of time in a given environmental condition.[Lyu, Xie] .Before a software released into market an extensive test is conducted
Assuming that the error detection rate in software testing is proportional to the current error content and the proportionality depends on the current test effort, a flexible software reliability growth model based on non homogeneous Poisson process is developed and its applications are presented
Summary
Reliability is one of the key factors in accessing the quality of the software. In past many papers are published in accessing the software quality through reliability. The TEF which gives the effort required in testing and CPU time the software for better error tracking. This paper describes the time dependent behavior of testing – effort by a generalized modified weibull curve. Assuming that the error detection rate in software testing is proportional to the current error content and the proportionality depends on the current test effort, a flexible software reliability growth model based on non homogeneous Poisson process is developed and its applications are presented. Section-2 proposed the test-effort function described by generalized modified weibull curve. In Section – 3 a software reliability growth model with the generalized modified weibull test effort function is discussed. Section-6 presents the prediction of optimal release time based on the application of the model to software reliability management
