摘要： 面向软件服务在其完整生命周期中长期持续优化运行的需求,从环境建模的角度提出一种支持软件服务持续优化运行的服务环境模型.基于Pareto占优原则直接面向多维质量指标自底向上筛选服务,形成支持软件服务所有实例优化运行的最优服务环境,并通过随服务空间变化动态更新最优服务环境实现对软件服务优化运行的持续支持.给出了服务环境模型的定义及最优服务环境的初始构建和动态更新机制,实验验证了所提出的服务环境模型对软件服务持续优化运行的支持效果.

Abstract: From the point of view for environment modeling, a service environment model was proposed to meet the continuous optimization execution of software services in their life cycle. On the basis of Pareto dominance, services were selected by their multiple quality criteria from bottom to top to form a minimal exhaustive service set (optimal service environment) for all executing instances. The continuous support of optimization execution of software services was realized by dynamically updating the optimal service environment with service changing. The definition of service environment model was given, and so were the methods for initially constructing and dynamically updating the optimal service environment. Experimental results indicated the validity of the proposed service environment model.
