Description: 本分析了单一模型和混合颤测模型的原理及
建模思想，将混合预测模型弓I入财务困境问题的研究，并通过筛选选取r 20个
财务指标构建预警模型。由于前人研究使用的“配比，’样本选择具有较强的主观
性，作者尝试性的采用随机选取方式在我国2007年深沪两市的1413家上市公司
中抽取了三组样本，分别用于训练和检验。最后对单一模型和三组混合模型进行
了比较分析，结果显示组合预测模型的精确性、稳健性等方面优于其他模型，有
着更好的预测效果。-This analysis of a single model and the hybrid model of VF measurement theory and modeling of thought, I bow to hybrid prediction model study into the issue of financial distress and, through the filter select r 20 sets of financial indicators to build early warning models. Because previous studies using the " proportion, ' sample selection has a strong subjective, the authors try to approach of using randomly selected cities of Shenzhen and Shanghai in China in 2007 listed companies in 1413 to extract the three groups of samples, respectively in the training and testing. Finally, a single model and the three groups carried out a comparative analysis of mixed model showed that combination forecasting model accuracy, robustness, etc. is superior to other models, has a better prediction.

Description: 网络服务正在更新换代并且可扩展设备被设计成可提供在元计算环境中动态资源行为预测。这篇文章里，我们描述了预测产生的的设计和预测行为的细节。当预测方式为普通方式时，我们关注与他对TCP/IP端到端吞吐量能力的预测和在不同地点使用不同系统会带来的延迟量。因为在元计算软件的基础上网络预测需要计划的支持和质量服务保证的提高。-The Network Weather Service is a generalizable and extensible facility designed to provide dynamic resource performance forecasts
in metacomputing environments.In this paper,we outline its design and detail the predictive performance of the forecasts it generates.
While the forecasting methods are general,we focus on their ability to predict the TCP/IP end-to-end throughput and latency that is
attainable by an application using systems located at differentsites.Such network forecasts are needed both to support scheduling
(Bermanetal.,1996)and,by the metacomputing software infrastructure,to develop quality-of-service guarantees(DeFantietal.,to
appear Grimshawetal.,1994).
