孙凯  冯晓川 《中国科技信息》2011,(12):139-141

数字电视整体转换给广电运营商带来前所未有的历史机遇,＂三网融合＂政策为广电综合业务的开展拓展了更宽阔的途径。通过技术和政策的推动,广电运营商彻底改变了以往业务单一、经营粗放的困境。运营支撑系统由于其自身的灵活性和可扩展性,作为广电整体转换后,所有业务统一接入和管理的综合平台,在广电实际运营过程中扮演着越来越重要的角色。本文通过介绍现代广电运营支撑系统的基础＂eTOM模型＂和一个实际建设的案例,说明在实际运营中,系统所起到的重要作用。  相似文献

Reliability modelling and analysis of a two unit continuous casting plant     

A.G. Mathew  S.M. Rizwan 《Journal of The Franklin Institute》2011,348(7):1488-1505

The aim of this paper is to present a reliability modeling and analysis of a two-unit system of a continuous casting (CC) plant. Real maintenance data of a steel production plant have been used for the purpose. Three types of failures were noted: repairable, replaceable and reconditioning/reinstallation. The two-unit system is operating in parallel, on full-reduced installed capacity. Upon the unit failure, an inspection is carried out to decide the type of maintenance task to be performed. Optimized reliability indices of the plant such as mean time to system failure, availability, expected busy periods of the repairman for various maintenance tasks, expected number of visits by the repairman, expected number of repairs, replacements and reconditioning/reinstallation are obtained. Semi-Markov processes and regenerative point techniques are used for the analysis. Profit incurred to the CC plant is also evaluated and related graphs are plotted to demonstrate the results.  相似文献   

Enterprise Information Portals in support of business process, design teams and collaborative commerce performance     

Hsin Hsin Chang^{Author Vitae}  I. Chen WangAuthor Vitae 《International Journal of Information Management》2011,31(2):171-182

Enterprise Information Portals (EIPs) have been widely adopted as platforms for the integration of knowledge management and information technology (IT). This study has been conducted from the knowledge management perspective in order to examine the influence of EIPs on collaborative commerce in the automobile industry. This study explores the integration of internal and external business processes and the coordination of collaborative design teams. An initial qualitative investigation explores the practical applications of an EIP in an automobile company. A research model is then formulated and tested using a questionnaire survey of the R&D department of a motor company in Taiwan. The results of the data analysis reveal that presence of EIPs can help a company realize the benefits of c-commerce. EIPs also can improve collaborative commerce performance by promoting the degree of integration of the enterprise process and by strengthening the process innovation and communication of collaborative design teams. The results suggest that managers should reinforce important factors, including knowledge management tools, process integration, and the quality of design teams, in order to achieve success in collaborative commerce.  相似文献   

Analyzing the impact of knowledge management on CRM success: The mediating effects of organizational factors   总被引：1，自引：0，他引：1  

Aurora Garrido-Moreno^{Author Vitae}  Antonio Padilla-MeléndezAuthor Vitae 《International Journal of Information Management》2011,31(5):437-444

Customer relationship management (CRM) and knowledge management (KM) have become key strategic tool for all companies, especially in the current competitive environment. Moreover, customer knowledge is an important issue for CRM implementation. Reviewing the literature, we found many studies that analyze the crucial role played by KM initiatives as determinants of the success of CRM. Moreover, we found also diverse studies that show high rates of failure when implementing that strategy, so there is still no integrated conceptual framework to guide companies to their successful implementation. In this paper, with data of 153 Spanish hotels, we examine the relationships between KM and CRM success using a structural equation model. The main contribution is that having knowledge management capabilities is not sufficient for the success of CRM, but there are other factors to consider. In particular, organizational factors indeed impact CRM success and they appear to be intermediaries of the impact of other factors (KM capabilities/technological/customer orientation factors) in the success of CRM (in financial and marketing terms).  相似文献

企业影响政府/行业的能力与新产品绩效关系研究   总被引：3，自引：2，他引：1       下载免费PDF全文

赵文红  原长弘 《科学学研究》2011,29(6):906-913

 转型时期的中国,高度不确定的环境往往是因为政府政策和干预行为的连续变化以及高度的行业竞争带来的。基于动态能力的资源观点,企业影响政府的能力和影响行业的能力是企业适应外部环境的动态能力之一,这两种能力可以降低政治环境和市场环境的不确定性,从而提高新产品开发绩效;并且政府干预对两种能力与新产品绩效的关系具有一定的调节作用。应用分层多元回归模型,对陕西省178家企业的问卷调研数据进行分析。研究结果表明,这两种能力对新产品绩效都有积极的促进作用,且两者的交互也将促进新产品绩效;政府干预对两种能力与新产品绩效关系的调节是倒U型的,即适量的政府干预可以促进两种能力与绩效之间的积极关系,而当干预过多,则降低了企业的柔性,削弱了企业对环境的敏感度,从而对两种能力与新产品绩效之间的积极关系产生消极作用。  相似文献
