Abstract
The current software development environmenthas been changing into new development paradigms suchas concurrent distributed development environment and theso-called open source project by using network computingtechnologies. Especially, OSS (Open Source Software) systemswhich serve as key components of critical infrastructuresin our society are still ever-expanding now. However,poor handling of quality attainment and customer supportprohibit the progress of OSS. We focus on the problems inlow software quality that prohibit the progress of OSS.In case of considering the effect of the debugging processon an entire system in the development of a method ofreliability assessment for open source project, it is necessaryto grasp the deeply-intertwined factors, such as programmingpath, size of each component, skill of fault reporter,and so on. In order to consider the effect of each softwarecomponent on the reliability of an entire system under suchOSS development, we propose a new approach to softwarereliability assessment by creating a fusion of neural networksand the software reliability growth models. Also, it has beennecessary to manage the software development process interms of reliability, effort, and version-upgrade time. In thispaper, we find the optimal version-upgrade time based onthe total expected software maintenance effort by using oursoftware reliability growth models.
