A Method of Parameter Estimation in Flexible Jump Diffusion Process Models for Open Source Maintenance Effort Management

Abstract

We focus on several irregular behavior under jump in the operation performance of open source software (OSS). This paper proposes a flexible jump diffusion process model (JDPM) to several jump processes for maintenance effort in the OSS usage associated with version upgrade. Especially, we discuss a method of parameter estimation based on the flexible JDPM considering the unexpected irregular behavior in major version upgrade transition for the project of OSS. Also, it will be useful for the managers of OSS to measure the status of maintenance effort with OSS major version upgrade in terms of the quality management. Moreover, The actual data is analyzed to present the numerical illustrations based on the proposed parameter estimates considering the characteristics with major version upgrade under OSS operation.
