Combined HW/SW Reliability Models.
Abstract
A general methodology is developed for combining hardware and software reliability. Based on this general methodology, a baseline combined HW/SW reliability was developed incorporating and unifying the SW reliability theory of Jelinski-Moranda, Goel-Okumoto with traditional HW reliability theory. The baseline model is computerized and includes various HW/SW failure and repair characteristics, allowance for imperfect SW debugs and modes of HW/SW interaction. Finally a HW/SW tradeoff procedure is developed using a combined HW/SW availability measure. Examples are provided to illustrate the general theory and tradeoff procedure. (Author)
