PFIs involving multiple public partners: a case study from the Italian healthcare sector

The financial crisis experienced by many countries since 2008 has given new importance to private finance initiatives (PFIs) for providing public services. This paper analyses the relationships between multiple public and private sector actors participating in a PFI in the healthcare sector in order to better understand the motives and behaviour of public and private sector partners. High levels of trust and the active participation of a regulatory body were found to be significant factors in terms of creating a partnership that benefits all sides.     

基于Virtual.Lab的某电动车平顺性研究

针对某低速电动车动力学系统建模的问题,采用Virtual.Lab软件的Motion模块,建立整车动力学模型.该模型考虑车身和刚性较弱的主要承重部件的变形,进行刚柔耦合分析,保证整车动力学模型与实车一致.为保证性能的准确评判及考虑实际路面激励,建立低频平顺性和高频平顺性两种平顺性评价工况,基于ISO 2631-1标准,提出每个工况下的评价指标和10个评价位置点.为明确平顺性优化方向,建立整车参数化分析方法,对底盘参数进行灵敏度分析,确定每个参数的影响特性,确定优化对象,为整车平顺性能研究提供一种清晰的分析思路.     

航材供应链管理研究

传统的航材保障中的信息共享和信息技术水平较低,供应链的思想和技术是解决这一问题的途径。航材供应链对传统的航材保障进行一定的业务重组、信息化改造,提高了信息流管理的及时性、准确性,降低了航材经费。利用数据仓库和数据挖掘技术将航材供应链管理信息系统升级为基于数据仓库的决策支持系统,可以满足当前航材预测、辅助决策的需要。     

集体建设用地使用权流转的博弈行为分析

大量研究表明,尽管国家在政策和法律上采取诸多限制,集体建设用地使用权或明或暗的流转仍然大量发生.从流转主体间的利益博弈过程分析入手,论证集体建设用地使用权流转的客观必然性,为国家逐步放开限制和规范流转提供理论参考.通过重点构建集体建设用地使用权流转的利益博弈模型,求解表明:集体建设用地使用权流转是转出者、转入者和地方政府三方重复利益博弈的必然结果,因为无论何种条件下,流转都将有助干增加流转各方的预期收益.面对流转的大势,变堵为疏,采取有效措施规范和促进集体建设用地使用权的合理有序流转,避免土地收益流失和市场混乱等问题,是未来我国土地管理制度改革的一项重要内容.     

国际金融危机背景下我国利用外资的思考

2008年10月以来,我国吸收外商直接投资数已连续9个月呈下降趋势,形势比较严峻。尽管我国经济率先复苏的信号渐趋明朗,国际资金流出现回稳态势,预计未来FDI降幅会继续收窄。但我们面临的内外部环境仍存在较大不确定性。我国应及时调整政策,采取有效措施：统一外资立法,健全外资并购的法律制度;增强FDI对中国市场环境的信心,改善投资软环境;优化外商投资产业结构;加大服务业招商引资力度,创造良性发展的服务业引资环境等。这样,才可能化“危”为“机”,继续发挥外资在我国经济中的积极作用。     

应用轨迹灵敏度计算临界切除时间的新方法研究

文章提出了一种可以描述故障后系统稳定程度的灵敏度指标,根据系统稳定性逐渐恶化指标趋于零的特点,计算了系统部分参数的临界值;根据稳定指标与故障切除时间在一定范围内的良好线性关系,估算了系统故障临界切除时间;并在单机无穷大系统与10机典型新英格兰系统下进行验证,证明了该方法的正确性。     

农业灌溉投资与灌溉用水的替代弹性分析

本文基于CES生产函数,利用我国12个省份2003-2005年的面板数据,实证分析了农业灌溉用水量与农田灌溉水利投入之间的关系.结果表明,亩均灌溉用水量与灌溉投资之间有较大的替代弹性,存在着很强的替代关系,这说明在给定的产出水平下,政府部门可调动多种投资主体的积极性,提高灌溉投资水平,达到对灌溉用水的替代,实现节约农田灌溉用水的目的.     

New Approaches to Business Process Redesign: A Case Study of Collaborative Group Technology and Service Mapping

Whether it is called reengineering, quality function deployment, quality circles, continuous improvement or total quality management, business process redesign (BPR) is occurring in many organizations. In the broadest sense, BPR includes nearly any kind of systematic effort by companies to realign their business processes so that they are more competitive. Successful business process redesign can lead to dramatic improvements in productivity and quality. But BPR typically requires vast amounts of time and money to implement, since extensive employee input is necessary during the redesign process. Group Decision Support Software (GDSS) provides a viable alternative to the traditional BPR approach. GDSS is defined as computer-based information systems used to support intelligent, collaborative work.This technology allows multiple users to meet and discuss topics simultaneously via a computer network, thus increasing employee commitment while decreasing time and cost.This paper describes a business process redesign project that was conducted for a division within a large government agency fall of 1993. The BPR was done using a type of Group Decision Support Software called Group Systems V. A services marketing tool called service mapping was also used to identify customer needs and interfaces. Data were collected throughout the project to measure employee attitudes about the redesign process and the GroupSystems technology. Time to complete tasks was also recorded. The results of the study showed that the business process redesign was accomplished more effectively in a shorter period of time than with traditional BPR methods previously used. Participants also indicated that the service mapping tool provided a perspective that is missing from many BPR approaches: an understanding of the service from the customer's perspective.
