中文摘要：
针对现有服务工作流性能评价模型的兼容性和可扩展性问题,设计并实现一种面向用户需求并支持QoS调度的服务工作流性能评价系统SWES（Service workflow evaluation system）。该系统采用组件技术及面向对象编程方法设计,各个组成部分通过标准的SOAP协议通信,使得各模块的组织及建立能独立实现,同时连接网络中UDDI对服务资源进行整合,使系统具有较强的可扩展能力。该系统既提供了用户个性化定制的功能,又能对传统调度算法的QoS指标及扩展QoS指标进行性能评测。实验结果表明,该系统具有较强的兼容性和可用性。
英文摘要：
Based on the deficiency of compatibility and expansibility for service workflow performance estimation modules, a novel service workflow evaluation system （SWES）, which was to meet the user＇s demand and support QoS scheduling, was designed and implemented. The technologies of component structure and OOD were adopted in the system, and every module was organized and constituted independently. The standard SOAP protocol was used for the communication between its components, and the service resource in the internet was integrated by UDDI. SWES can make the users customize individuation workflows, and estimate QoS performance of the traditional scheduling algorithms and the extend QoS performance. The experimental results show that the SWET is compatible and applicable.
