Abstract: The service scheduling is analyzed firstly.Based on the result of analysis，the service scheduling is discussed.The composition of the dynamic scheduling system，the system architecture and the implementation technology in grid service are investigated.The service scheduling named G-Sched is designed and implemented which can accomplish the need managing in serving of the net lattice.Lastly，an analog network virtue fabrication is applied as an example.The example proves that the proposed methods in this paper are available and effective.

Key words: grid scheduler, grid service, open grid service architecture, service scheduler

摘要： 针对当前网格调度体制的研究仅从功能需求、执行过程方面进行描述，尚未对调度过程中的接口和交互协议进行定义，缺乏对语义支持的现状。结合语义Web服务技术，从实现角度讨论服务网格环境下的调度机制。从分析服务调度过程入手，讨论服务网格中动态调度系统的组成、系统架构及实现技术，初步设计和实现能够完成服务网格中调度需求的服务调度组件——G-Sched，并以模拟网络化虚拟制造作为应用示例来验证所提出方法的可行性和有效性。
