企业集群成本协同管理效应研究 [PDF]

open access: yes, 2009
本文旨在突破交易成本理论的约束,应用企业网络理论并结合企业集群协同创造价值的特点,来揭示企业集群上下游的成本协同管理需要考虑的问题。依据所揭示的问题和已有的研究成果,我们提出了集群成本协同管理的协同效应假设,应用问卷调查收集数据和统计分析方法证实了所提出的假设,得到如下的结论:在企业集群中,成本协同管理的认同度和上游企业的配合程度越高,核心企业的作用越大,集群成本协同管理效应就越大;同时,研究也支持了企业网络理论的协同管理机制可保障增加协同效应 ...

AVEVA异地协同技术在海洋石油工程三维设计中的应用

open access: yesHaiyang gongcheng zhuangbei yu jishu, 2016
介绍了AVEVA异地协同技术的原理。针对AVEVA异地协同技术的缺陷,开发了PDMS后台管理程序。部署了两种方案,对AVEVA异地协同技术在单个项目中的应用以及基于PDMS后台管理程序的多项目中的应用进行了研究。结果表明,AVEVA异地协同技术可以有效实现不同设计中心在同一个三维模型中实时同步设计的目标;开发的PDMS后台管理程序有效地解决了AVEVA异地协同技术的缺陷,在稳定实现多项目实时同步更新设计数据的同时节省了软件资源,创造了良好的经济效益。
