Abstract This paper focuses on several irregular fluctuation in the operation performance of open source software (OSS). We apply a flexible jump diffusion process model to several noisy cases in the operation of OSS associated with version upgrade. In particular, we propose a method of maintenance effort management based on the flexible jump diffusion process model considering the irregular fluctuation in version upgrade performance for OSS projects. Thereby, it will be helpful for the OSS project managers to understand the effort status with version upgrade of OSS from the standpoint of OSS project management. Moreover, we analyze actual data to show numerical examples of the proposed method considering the characteristics with version upgrade of OSS projects.
