Abstract

To analysis the influence of application of design patterns to software safety, we carry out a case study on bridge pattern with SFTA (software fault tree analysis). The result shows that the application of bridge pattern will make the safety reduce 50%, but the introduction of the pattern can decouple the software modules and redundancy design can be added. Double redundancy will improve software safety by 2 orders of magnitude. The conclusion is valuable for object-oriented design of safety-critical software and the method can also be used to analyze safety of other design patterns.
