OSS Project Stability Assessment Support Tool Considering EVM Based on Wiener Process Models

摘要

The method of earned value management is traditionally applied to the progress assessmentof actual software projects in many IT companies. Also, Open Source Software (OSS) are used underthe various situations because of cost reduction, standardization, and quick delivery. In particular,many OSS are developed and managed by using fault big data recorded on the bug tracking systems.Several research papers in terms of OSS reliability assessment have been published in the past.The fault is caused by the poor handling of effort control. Therefore, we can make a stable and safetyoperation for OSS system if the OSS project is appropriately managed by using the software effort.The OSS effort estimation model by using a conventional stochastic differential equation model isdiscussed in this paper. Then, we propose the optimal maintenance problem based on the earnedvalue requirement. In particular, we develop the OSS project stability support tool. Furthermore,several performance illustrations of the developed software tool are shown by using the effort dataunder actual OSS project.
