摘要: 为支持在用户主导、虚拟组织形态的问题求解环境中,透明访问分布、异构的Web服务资源,提出一种支持业务需求变化性的服务虚拟化机制。基于业务需求变化性的描述方法,给出了蕴含变化性的虚拟服务的描述模型,并基于服务匹配、变换以及特征的求解方法,提出了支持需求变化性的虚拟服务与Web服务之间的虚拟化和具体化操作。分析和实验表明,该机制在支持用户需求变化性的同时,提高了用户使用服务的效率。

Abstract: To enable users to access heterogeneous Web services transparently in problem solving environments based on virtual organization mechanisms, a service virtualization mechanism supporting the variability of business requirements was proposed. A virtual service model was proposed based on the description model of business requirements variability, which could support various requirements. Operations for virtualization and concretion were also defined base on the proposed approaches to service matching, transformation, etc. The analysis and experiments show the proposed mechanism can improve the efficiency for handling services.

Key words: service virtualization, concretion, semantic, requirement variability
