E-Book Overview
1991 - 107 pThis report presents the results of the first phase of the ongoing EG&G Idaho, Inc. ,Software Reliability Research Program. The program is studying the existing softwarereliability mc:lels and proposes a state-of-the-art software reliability model that is relevant tothe nuclear reactor control environment.This report consists of three parts: (1) summaries of the literature review of existingsoftware reliability and fault tolerant software reliability models and their related issues, (2)proposed technique for saitware reliability enhancement, and (3) general discussion and futureresearch.The development of this proposed state-of-the-art software reliability model will beperformed in the second phase.
