Software Evolution Method Considering Software Historical Behavior

The goal of software evolution research is to use the history of a software system to analyze its present state and to predict its future development, which made people can better use and management software In this paper, a process of changing normal software into autonomic software is described, which add autonomic attribute in software. Relationship and operation of components for software evolution is defined and the process of software evolution mechanism is depicted in this paper. A software evolution method considering software historical behavior is proposed for maintaining the dependability of software in a stable and non-reduced level. The simulated results produced by the designed experiment show that the method is validity in maintaining and increasing the dependability of software.
