In this thesis report the pertinence of the models (Neural Network model and Hellinger Net model) for better software reliability prediction considering the parameters and software metrics affecting the software design in a real environment is described. And a method of software defect detection and software reliability assessment using NN model and Intelligent Water Drop (IWD) Technique is presented. Built on a Neural Network (NN), two models are developed which predicts the software reliability in a more accurate manner. There are two kinds of hybrid models developed. One uses IWD with NN and another is IWD with Spiking Neural Network (SNN).
For both, the modelling feature selection technique and learning algorithm is implemented and the data representation methods and some metrics associated with software reliability models are discussed. Various datasets containing metrics values with software failures are applied to the proposed models. These datasets are acquired from variety of software projects.

Excerpt from the Book
1.1 INTRODUCTION
The use of software is expanding all the time, from simple home appliances to research and high-end scientific applications. With the advancement in electronic objects and digital computers our day-to-day life is fully reliant on such gadgets. As a result, there is a greater trust on software, requiring noteworthy advances in software reliability and its test procedures. The topic of utmost significance now is reliability of such software systems (Lyu,1996). This system can be divided into subsystems and components that are interlinked together. Hence the overall reliability of whole system is a combined effect of its components reliability and system-functions in which these components may not work individually or independently. The system is composed of various factors like hardware, software and human, but from an operations perspective, software is the main cause of system reliability. Hence Software Reliability is the main factor for system reliability.
The field of science and technology is always in demand of well reliable hardware and software. Increased software demands have caused changes in way of design, and maintenance of high-quality software. Despite the fact that hardware reliability is also a major concern, there is a clear link between software design techniques and reliability. The primary distinction between software and other engineering artefacts is that software is created rather than produced. In this created software faults in the design results into unreliability. And to overcome this there is trend of development of defect free software by making exhaustive testing and debugging techniques. The quality assurance teams and project management teams are always looking for ways towards the growth of software reliability from time to time during the development process. So as to make whole process cost effective and within the time span. Therefore, there is a requirement of comprehensive engineering approach which establishes the significance of Software Engineering which can give a systematic discipline methodology for the development of software.
