Research on building trustworthy software system by self-adaptation

Abstract

The execution context of today's software systems changes continually, which makes systems have to cope with changing environments while at the same time facing high non-functional requirements such as flexibility and dependability. Runtime adaptation technology can modify behaviors and structures in response to changes in the system itself or in its environment and thus improve dependability at run time. This leads to a more flexible and effective way to build dependable software system. However, current works address adaptation often remain a neglected gap between the architecture model and the system state. To solve this problem, we present a systematic process that covers requirements modeling, architecture and system modeling of trustworthy software based on a runtime self-adaptation perspective.
