Hazard Rate Model Considering the Change of Requirements Specification for the Porting Phase of an Embedded OSS

Abstract (in Japanese) (See Japanese page) 
(in English) The successful experience of adopting the distributed development model in such open source projects includes GNU/Linux operating system, Apache HTTP server, etc. Especially, an embedded OSS (Open Source Software) known as one of OSS has been gaining a lot of attention in the embedded system area, i.e., Android, BusyBox, TRON, etc, because of the cost reduction, quick delivery, work saving. However, the poor handling of quality problem and customer support prohibit the progress of embedded OSS. Therefore, many companies have been hesitant to innovate the embedded OSS, because an OSS includes several software versions. Also, it is difficult for developers to assess reliability and portability of the porting-phase in case of installing the embedded OSS on a single-board computer. In this paper, we propose a method of software reliability/portability assessment based on a hazard rate model for the embedded OSS. Especially, we analyze actual software failure-occurrence time-interval data to show numerical examples of software reliability/portability assessment considering the change of requirements specification. Moreover, we show that our model may assist quality improvement for embedded OSS systems development.
