扩展Tropos目标模型驱动的软件自适应方法研究

Extended Tropos Goal Model Driven Software Adaptive Techniques

传统模型驱动自适应方法通常使用软件设计阶段的体系结构模型引导软件运行时自适应行为,导致自适应策略模型复杂度较高。为此,论文将抽象级更高的需求阶段目标模型用作软件自适应过程中的策略模型,提出一种目标模型驱动的软件自适应方法。与体系结构模型驱动方法相比,由于该方法可忽略不必要的细节,因而能够降低策略模型复杂度,有利于自适应策略的维护、扩展和重用。

Traditional model-driven adaptive techniques usually use design phase architecture model to direct software runtime adaption behavior,which leads to the high complexity of the adaptive policy model.Therefore,this paper uses the higher abstract level requirement phase goal model as a strategy model of the software adaption process,and proposes goal model-driven software adaptive method.Compared with the architecture model-driven method,the method can reduce the complexity of the strategy model,which is beneficial to the maintenance,extension and reuse of the adaptive strategy.
