Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Software requires change throughout its lifetime which has been found to be a particular problem in terms of schedule, budget, and quality. The problems are most extreme important for critical software that needs to be validated if the changed requirements will affect safety. Therefore, the change impact analysis is so important in safety-critical system. This paper proposes a method to analyze the change impact analysis in a quantitative way with risk probability. First, a complete safety assessment model and a reliable model to trace the change are proposed based on probabilistic assessment. A case study on well-known systems, such as pressure systems, is analyzed. Then the application of our proposed traceability method is discussed which proves the applicability of our approach in change impact analysis.
