for A Nuclear Power Safety System", IEEE Transactions on Nuclear Science
Although there are several measurement and model based approaches to assessing the
compliance of critical computing systems with reliability requirements, applying
these approaches requires sophisticated data analysis and mathematical skills so
that reliability engineers often hesitate to perform such a task. The need to develop
cost effective, credible, and easy-to-use tools to reduce difficulties in performing
such tasks has thus been apparent. This paper presents a tool of this kind:
MEADEP.
MEADEP integrates techniques in graphical
user interface programming, database engineering,
dependability modeling, and statistical/numerical analysis, and provides a user-
friendly interface for non-expert users. Use of MEADEP
on failure data from measurements produces quantitative evaluations of dependability for
critical systems, while greatly reducing requirements for specialized skills in data
processing, statistical analysis, dependability modeling and model solution from the user.
The application of MEADEP
on safety systems is demonstrated by modeling dependability for
a nuclear power plant safety system based on the Eagle 21 architecture and its early field
failure reports.
