一种网络性能评价指标制定框架

文章针对网络测量中性能指标的定义问题,提出了一种基于协议的性能指标制定框架模型,这种模型下,性能指标的制定不依赖于应用系统。因而它能解决应用多样性给性能指标制定带来的困难,制定少量性能指标就能满足网络性能测量的普遍需求,并且制定的性能指标集合比较稳定。

虚拟企业性能评价指标框架

提出了虚拟企业的性能评价指标框架 ,涉及投入、产出、柔性和敏捷性 4个关键因素。投入评价以虚拟企业生产的产品为中心 ,分别计算供应商、制造企业和分销商的成本 ;产出评价包括最终产品和客户服务 ;柔性评价度量了企业在市场需求量、产品品种、交货日期、新产品开发发生变化时所具有的弹性 ;敏捷性评价给出了企业状态、敏捷性属性和敏捷性属性组之间的联系 ,以及企业敏捷性的计算模型。

在线事务处理系统性能评测框架研究

在线事务处理(online transaction processing,OLTP)系统在不同的应用环境下存在着模型的差异,但是作为典型的数据库应用系统,其在不同应用下的性能评测又存在着一定的共性。针对用户自身应用领域的性能评测环境,提出了一种针对OLTP系统进行性能评测的通用框架,用户可以动态配置数据规模、事务混合比例等测试参数。在框架基础上,以银行中间业务这一典型的OLTP应用为例,实现了面向银行中间业务的OLTP性能评测系统,通过实验验证了评测系统及所提框架的有效性。

Determinants of international joint venture performance measurement： A theoretical framework

International joint ventures （IJVs） have increasingly their role in business world and also in research field of international business. There have been a lot of studies related to determinant factors of IJV performance. However, there are very few studies focusing on the measurement of I Jr performance. Especially, researchers have ignored how foreign parent firms really choose their measures in the evaluation of their IJV performance. This research investigates determinant factors of performance measures of 1JVs. Determinant factors of IJV performance measures include motives for establishment, establishment mode, location of IJVs, distribution of ownership in IJVs, cultural background of parent firms, and trust between partners, IJV life stages, parent firms＇ international experience, and relatedness of the IJVs to their parents. Performance measures are divided into financial measures and non-financial measures. The paper shows how different determinant factors are expected to lead foreign parent firms preferring one kind of measure over the other.
