D. Tang, H. Hecht, M. Hecht, "A Methodology and Tool for Measurement-Based Dependability
Evaluation of Digital Systems in Critical Applications", IEEE Transactions on Nuclear
Science, August, 1996
This paper presents an overview of a measurement-based methodology for dependability
evaluation of critical digital systems and describes a software tool under development
for it. The approach is based on measurements of operational systems and on dependability
models to provide quantitative reliability and availability assessments with stated
confidence levels. The methodology is described, and some of the lessons learned
in its early use are discussed. The design of a software tool to implement the methodology
is outlined and the current experience in applying the methodology is summarized.
