Estimation of Reliability and Cost Relationship for Architecture-based Software

In this paper,we propose a new method to estimate the relationship between software reliability and software development cost taking into account the complexity for developing the software system and the size of software intended to develop during the implementation phase of the software development life cycle.On the basis of estimated relationship,a set of empirical data has been used to validate the correctness of the proposed model by comparing the result with the other existing models.The outcome of this work shows that the method proposed here is a relatively straightforward one in formulating the relationship between reliability and cost during implementation phase.
