摘要
面向特征的领域分析方法可为网构软件中资源的有序化提供有效支持.从领域工程的角度出发,提出一种特征模型驱动的网构软件组装与优化方法,该方法以iJackson图描述网构软件的特征模型,结合软件体系结构特点,分析了将特征模型转换为面向业务构件、基于工作流图技术的组合模型的机制,通过应用图论方法,将组合模型建模为以领域特征簇为中心的构件组装结构图,围绕面向多目标需求的QoS模型,建立了Internet环境下网构软件构件组装问题的数学模型,提出了一种基于蚁群优化算法的全局优化方法.最后,以网上书店系统为例,介绍了仿真实验过程,并说明了方法的有效性和可行性.
The method of featureoriented domain analysis can support efficiently ordering resources for Internetware. In terms of do- main engineering, a feature model-driven method of component composition and optimization was proposed, in which the i-Jackson graph was used to describe the feature model of Intemetware, and a transformation mechanism from feature model to business compo- nent-oriented composition model based on workflow graph was presented. By employing graph theory, the component composition structure graph centering on domain feature cluster was put forward on the basis of composition model. A multi-objective QoS model was defined, and the mathematical model of component composition was established for lntemetware in Internet environment, and ant colony optimization algorism was introduced to solve the global optimization problem. Finally, prototype and related experiments proved that this method was feasible and effective.
