环境模型驱动的服务组合方法

Environment Model-Driven Service Composition Method

针对服务组合动态、开放、复杂度高的特点,提出了一种环境模型驱动的服务组合方法.该文用环境模型中服务作用下客体的变化来描述服务功能,用客户期望的环境变化描述客户需求,构建了一种独立于服务实现和具体客户的组合环境;然后以环境模型为基础分解需求和组合服务.实验结果分析表明,该文方法可以有效提高服务组合的效率.

To address the challenge of service composition that are dynamic, open and with a high complexity, the paper presents aservice composition method driven by environment model. In this paper, by projecting service functionalities and the custom re-quirement into the environment model, a closed and simple problem domain is constructed. And then a composition methodthrough decomposing the requirement is proposed. The test results show that this method is effective.
