Non-specialists might have the feeling that building statistics on businesses is a very simple task: it seems one just has to \"add facts\". But for survey statisticians, business statistics are extremely complex: great heterogeneity of the universe, definition of the statistical units, difficulty of classifying businesses, quality of the register, variety of accounting standards, sample co-ordination, or reduction of survey burden. This paper argues that the issues raised by business survey methodology are conceptual and not only practical. It describes different aspects of statistical processing and tries to analyse the special features of business statistics. 相似文献

网络在国民生产和生活中的逐步渗透对信息安全提出了严峻的挑战,应对此挑战的方法也只能通过对网络信息资源的监控来实现。本文将数据挖掘技术应用于网络信息安全监控,设计出一套基于网络数据挖掘的信息安全监控体系的概念模型。该体系通过多种方法对海量的网络数据进行收集,经过预处理后形成信息安全数据仓库,在此基础上进行数据挖掘,最终生成信息安全监控对象的特征信息和监控对象之间的关联信息,以达到对信息进行安全监控的目的。 相似文献

Input-output (IO) updating research indicates substantial improvements in the forecasts when some of the coefficients have been exogenously estimated and included in the updating process. Several methods for identifying the appropriate subsets have been proposed. The present paper attempts to assess the relative performances of two such approaches: 'the largest coefficients' and 'the most important parameters' criteria. Utilizing these criteria, a set of coefficients from the 1966 IO table of the former Soviet Union were selected and exogenously determined. The remaining coefficients were updated to 1972 by means of naive, RAS, and Lagrangian techniques. Comparison of the results with the 1972 benchmark table provided the desired answers. 相似文献

Under the structure of multiple business entities, supply chain management (SCM) offers the external and internal integration
of business processes in enterprises. The most important objective of SCM is to enhance the supply chain performance such
as reinforcing the service level and increasing profit as well as reducing order cycle time and inventory. In recent years,
due to the advancement of information technology, enterprises can manage the product flow and the information flow via economical
and efficient mechanisms. The well-organized information sharing can enhance the supply chain performance and allow enterprises
to refine their strategies of supply chain in order to maximize their profits. The previous studies pointed out the positive
effect of information sharing on the efficiency of supply chain. However, relatively little literature focuses on the performance
analysis for multi-echelon supply chain with various information sharing scenarios. By using the simulation technique, this
paper models different scenarios of information sharing, and further analyzes the impacts of information quality on multi-echelon
supply chain performance. In addition, this paper employs Data Envelopment Analysis (DEA) to integrate multiple performance
measures to ensure the information sharing scenarios with enhanced performance. 相似文献
