中文摘要：

在网络制造环境下,动态时间性能是分布式测量系统的重要指标.针对基于公共对象请求代理结构和尺寸测量接口规范的分布式测量系统,根据多用户非抢占优先排队网络静态性能模型,提出基于无穷小摄动分析的分布式测量系统动态性能评价算法.算法以分布式测量系统时间性能指标的在线变化为输入,动态调整排队网络系统服务台的窗口数量,从而实现对系统时间性能的动态调整.最后,在某制造工厂中进行了应用实验,证明了算法的有效性.

英文摘要：

Dynamic time performance was one of the key factors for Distributed Measurement System （DMS） in networked manufacturing environments. Based on no-preemptive priority queuing network model, new infinitesimal perturbation analysis schemes were presented to estimate the dynamic time performance of DMS based on Common Ojbect Request Broker Architecture （CORBA） and Dimensional Measurement Interface Standard （DMIS）. By inputting on-line changes of DMS time performance parameters, the schemes adjusted the number of service windows in queuing network system to regulate dynamic time performance. Application experiments in a factory demonstrated the effectiveness of the new schemes.
