Assessing Pareto Software Reliability Using SPC


Satya Prasad R, Sita Kumari K and Sridevi G

Software reliability is one of the most important characteristics of software quality and is very much essential for producing reliable software systems. The reliability of software can be monitored efficiently using Statistical Process Control (SPC). It helps to identify when the failure takes place during the software development process. In this paper we proposed a control mechanism based on the cumulative observations of the time domain data using the mean value function of Pareto type II distribution, which is based on Non-Homogeneous Poisson Process (NHPP). To estimate the unknown parameters of the model, maximum likelihood estimation method is used. The failure data is analyzed with the proposed mechanism and the results are exhibited through control charts.

Keywords: Control Charts, Mean Value Function, NHPP, Pareto type II distribution, Statistical Process Control, Time domain data.
