Research Abstract |
In this study, we construct several types of mathematical and stochastic model for evaluating the novel reliability characteristic, called "service availability" of software-based systems, considering the usage characteristics of the end-users. We define the software service availability as the probability that the software-based systems can satisfactorily complete the services the end-users require, and then derive several stochastic quantities for software service availability assessment as the functions of time and the debugging activities.
