Jump Diffusion Process Model for OSS Reliability Analysis

Many open source software (OSS) projects continues to increase around the world. Many OSS are operated under the irregular status of component-collision. In particular, several components of OSS will be made a change according to the progress of OSS development as time passes. Also, OSS include several versions such as bug-fix version, minor version, and major version, etc. Considering the characteristics of OSS projects, the operation performance of OSS development will take an irregular fluctuation during the operation, because several OSS components are updated by the OSS version-upgrade. In particular, the characteristics of OSS changes with the replacement of several components according to the numbers of several version upgrade. Several research works in terms of the reliability of OSS have been proposed by several researchers [1–3]. In the past, the methods of software reliability assessment based on the SRGM’s have been proposed by several researchers [4, 5].
