PDM在客车制造业ERP中的地位和作用

通过对PDM功能的理解及PDM与ERP相互关系的阐述。明确PDM和ERP在汽车制造业领域中既是两个相对独立的系统,同时又是密不可分的一个整体,它们在功能的相似性、重复性、关联性,完全可以就是一个系统、一个数据库．PDM实际上就是ERP功能扩展。ERP与PDM一体化集成是当前汽车行业发展的一个大趋势。     

基于JMS和Web Services的企业应用集成系统的设计与实现

自从企业应用系统被广泛使用以来,企业应用集成技术就随着应用技术的不断发展而产生变化。从最初的使用简单文件进行数据交换发展到RPCs、分布式对象、事务监视器,再到最近被广泛使用的消息系统和网络服务技术。从另一方面看,企业集成的角度也从单一向多层次的趋势发展。文中主要介绍如何基于JMS和Web Services技术设计和实现企业应用集成系统,通过这两种技术可以轻松解决其它EAI技术在使用中遇到的难题。

Critical success factors of supply chain integration in container shipping: an application of resource-based view theory

ABSTRACT

The container shipping industry is receiving growing attention in driving the performance of global supply chains. This phenomenon has accelerated supply chain integration (SCI) within the industry. Although SCI could offer numerous benefits, it is often quoted to be implemented easier in theory than in practice. The high failure rate that is associated with SCI is often not addressed in the literature. Grounded on resource-based view (RBV) theory, this paper is aimed at identifying the critical success factors (CSFs) and examining their influence on SCI and supply chain performance (SCP). Survey questionnaires were administered on 164 container shipping firms. The constructs were validated empirically using confirmatory factor analysis and were subsequently analysed using structural equation modelling. The proposed CSFs in this study are found to be positively corelated with SCI, which, in turn, is positively correlated with SCP. This paper has contributed to both theory and practice by applying RBV theory to identify the key resources and capabilities that are necessary for SCI in the container shipping industry.     

农村公路建设的社会经济效益分析

农村公路的社会经济效益是评价项目实施效果的重要依据。在分析了农村公路社会经济效益的产生机理的基础上,建立了一套较完善的农村公路社会经济效益评价指标体系。以浙江省"乡村康庄工程"项目为例,对本文建立的体系进行了检验,取得了较好的使用效果。     

基于结构可靠度的在役桥梁剩余价值分析

在BOT的交通基础设施建设模式下，转交政府相关部门后的基础设施从会计学的角度而言已经摊销完毕，但是从经济学角度而言。这些公共基础项目仍然发挥作用．产生着经济效益。对在役桥梁进行剩余价值分析，对于路政部门加强桥梁维护维修、加固甚至新建等决策管理都有实际意义。基于可靠度理论提出了一种折旧方法并用其进行剩余价值计算，为公共项目建设宏观经济的成本分析提供一种量化的工具。

公路建设项目经济评价概率分析

公路建设项目经济评价概率分析是研究不确定因素变化发生可能性的大小，以及在这种可能性下对评价指标的影响程度及项目获得收益的概率。运用离散性系统仿真原理，建立各风险因素概率模型，通过计算机产生(0，1)均匀分布随机数、各概率分布的随机变量，量化各因素对评价指标的影响程度，计算评价指标的风险概率。     

Effects of economic disincentives on private car use

A field experiment was conducted to investigate the effects of economic disincentives on private car use. Eighty two-adult households who were owners of at least one car were randomly assigned to three experimental groups and one control group. Both experimental and control groups logged their car trips during one week before, one week during, and one week after treatment. The treatment consisted of charging two of the experimental groups approximately 100% of normal cost per kilometer of driving during 2 weeks, and charging the third experimental group this amount per kilometer of driving during 4 weeks. With the purpose of investigating whether deliberate planning increases the effect of economic disincentives, the households in one of the former and in the latter group were asked to fill out a prospective car log for the following week. The control group was not charged or requested to fill out a prospective car log but was in other respects treated in the same way. Analyses of the car logs and odometer readings during and at the end of treatment showed a weak reduction of car use due to the economic disincentives that however were almost completely dependent on planning.
