SFTA Based Saftey Analysis for Bridge Pattern

摘要：

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 objectoriented design of safety-critical software and the method can also be used to analyze safety of other design patterns.
