A Reliability Analysis Framework for Domain Software Based on Degree Model

摘要

For the reliability analysis of domain software researching to present a comprehensive reliability analysis method of domain software based on evidence, and to establish the working framework. To form reliability evidence through analyzing and measuring the evidence that collecting from the software lifecycle, and to build up a evaluation mode to expression the reliability requirements; to define reliability degree and mapping method based on evaluation mode, and to describe software reliability by reliability degree; to analysis modeling the reliability based on formal methods, as well as to verification and validation models. The method combined of informal evaluation and formal analysis modeling has good maneuverability and good practicability. It can describe the reliability of domain software clearly, and provide support for constructing complete formal high reliability software.
