On Hazard Rate Modeling with Change-Point for Software Reliability Assessment
Shinji Inoue, Shiho Hayashida, Shigeru Yamada (Tottori Univ.) R2012-8
Abstract (in Japanese) (See Japanese page) 
(in English) A software hazard rate model is known as one of the important and useful mathematical model for describing the software failure-occurrence phenomenon and conducting quantitative software reliability assessment. In this paper, we discuss software hazard rate modeling with actual testing-environment, in which the testing-environment changes at change-point. Taking into consideration of the effect of change-point in software reliability growth modeling might be expected to conduct more accurate software reliability assessment because such approach enables us to reflect actual testing-environment. Especially in our discussion, we develop an exponential software hazard rate model with the effect of change-point as one of the examples of our modeling approach. Finally, we show numerical examples for our model and a result of model comparison by using actual data.
