Research And Implementation Of Task-Driven Self-adaptive Component Model

With the rapid development of information technology, Internet has graduallybecome a mainstream software environment. And open, dynamic and unruly are themost significant features of Internet. User requirement and computing environment tendto change much more frequently due to the open and dynamic characters of the networkwhich leads to the fact that the variation and complexity of software are furtherreinforced and the need of software robustness is also enhanced. How to better adapt tosuch network environment for computer software is a critical problem to be solvedpresently. And it has brought forward a series of challenges to traditional softwaredevelopment theory, method and technology. In order to go with this trend, people hasbegan to study it from different aspects. Moreover, most of them focus on “softwareself-adaptation” which makes self-adaptation become an indispensable ability ofsoftware and a core support technology of many applications.Based on the theories and techniques of self-adaptation and Agent and relying on acertain information processing platform, this paper mainly studies a basic computingand processing unit called task-driven self-adaptation component model which residesunder that platform. The model learns primarily from the ideas and conceptions oforganization and sociology and integrates Agent intelligence into its own to deal withrequirement variability. Firstly, this paper introduces a kind of task-orientedself-adaptation system development method. Then the formalization definition of theself-adaptation component model is presented, and describe the model from staticstructure and dynamic behavior angles separately, including its inner organizationstructure, dynamic binding mechanism and self-adaptation strategy. The related designand implementations are also illustrated. Finally, a typical application and a group ofexperiments are conducted to verify the feasibility and adaptability of the modelproposed in this paper, and an analysis has been made on the experimental results.
