| Research Abstract |
In this study, we construct several types of mathematical and stochastic model for evaluating reliability of software-based systems in the operation phase considering systemability, which is a novel concept of reliabiilty characteristic and considers the uncertainty and variability factors of the operational envoronment. Furthermore, we introduce the concept of systemability to the method for assessing the software service availability.We derive several stochastic quantities for software reliability and availability assessment as the functions of time and the debugging activities.
