An embedded OSS known as one of OSS’s has since been gaining a lot of attention in embedded system area such as Android, BusyBox, etc. However, the poor handling of quality and customer support prohibit the progress of embedded OSS. In this paper, we propose a method of software reliability assessment based on a flexible hazard rate model considering the influence of installer application. Also, we derive several reliability assessment measures. In particular, we show several numerical examples of reliability assessment based on our hazard rate model. Moreover, we formulate a total expected software cost model considering the environment for the usage of mobile device. Then, we discuss about the determination of optimum software release times minimizing the total expected software cost.
