Abstract—Owing to the low cost, high profit and disasterfree, the reliability-oriented evolution method is proposed in this paper. The method improves the reliability of software architecture by analysis contribution degree of component. Because the various components will play different roles in the reliability-oriented evolution of software architecture, the contribution degree of component is first put forward. It will be used for the reliability-oriented evolution in this paper. At the same time, the reliability-oriented evolution method of software architecture based on contribution degree of component is applied to an ATM system. The evolution process is illustrated by the method, and it shows that which component is playing an important or crucial role in the process of reliability-oriented evolution of software architecture. The reliability of software architecture will can be improved effectively and fleetly by the result.
