本文认为,为有效保证系统正常工作,实现给定功能,必须提高系统可靠性,而容错设计是提高系统可靠性的重要途径。物流系统容错技术能够自动、适时监测并诊断系统故障,然后采取相应的故障控制或处理方法自动修复或在线修复故障。文章提出,物流系统容错技术包括系统容错设计和系统故障诊断与检测等内容。容错设计的主要方法是系统冗余,应针对机械系统故障、软件系统故障、信息和控制系统故障等不同故障形式分别采用不同的冗余方法进行容错设计;应用测试技术进行故障检测与诊断能够在系统内发生故障时自动发现故障,确定故障部位和类型,并自动采取保护措施,常用的方法主要包括参数法、表决法、振动法及智能化专家系统等。  相似文献

区域经济系统演化的自组织机制研究   总被引:6,自引:0,他引:6  
区域经济因其内部众多要素之间的复杂关系,难以用传统的线性思维方式和数理方法研究其整体发展。系统论为更科学地考察区域经济发展规律提供了理论基础。文章通过对区域经济系统自组织演化的分析,深入研究区域经济系统演化的自组织条件、内在动力和源泉,认为:区域经济系统的自组织过程不具有稳定性,竞争与协作共同决定着区域经济系统的发展演化;地方决策机构应对区域经济自组织进行控制,把系统引向决策者所希望的有序结构。  相似文献

基于耗散结构的公司内部治理机制演化研究   总被引:1,自引:0,他引:1  
公司内部治理机制运行状态具备形成耗散结构的条件。基于耗散结构理论,分析了影响内部治理机制发展的内外部因素,并且制定了公司内部治理机制的耗散结构模型,使对系统演化方向的分析从定性转化到定量成为可能,借助模型得出系统在各因素的作用下三种可能发展方向及演进规律,为定量判断系统所处的发展方向、动态把握公司治理的实践奠定了基础。  相似文献

生态合作关系的建立与良性运转能够有效调动各方资源解决行业发展困境、共同互助提升。基于社会资本理论,研究探索了平台企业与合作伙伴如何识别不同阶段发展瓶颈、应对措施、产生结果等生态合作演化过程。以菜鸟平台作为案例研究对象,解锁了生态合作不同阶段的动态合作演化路径与规律。研究发现:(1)平台企业与合作伙伴共经历基于需求与供给的绑定、基于价值获取与能力提升、基于共生共赢的合作三个阶段;(2)三阶段分别着重于建立伙伴间连接与信任、提升伙伴能力与协同配合、增强伙伴责任共担、贡献自身的意识;(3)各阶段均形成以“瓶颈—策略—结果”为内在逻辑的合作演化路径,最终建立生态合作演化整合模型。研究通过拓展对社会资本理论的认知,深化了对平台生态系统领域内合作演化过程的理解。  相似文献

业态演化对零售商行为作用的理论模型与推论   总被引:2,自引:1,他引:1  
通过文献研究发现,有关渠道关系的研究十分广泛,但将零售业态作为渠道行为系统的外部影响因素,与渠道行为之间的相关性研究却是理论研究的空白.文章提出一个零售业态演化对零售商作用机理的概念模型,并作如此推论:渠道权力与渠道信任是零售业态演化作用于渠道行为的中介变量,在供零关系中起着基础的作用;同时随着零售业态的演化,供应商渠道权力作用会下降,而零售商信任的作用将提高,进而导致供零的冲突下降、零售商关系承诺、沟通与合作水平增加,而投机行为受到抑制,零售商的满意度随之提高.  相似文献

Similar to what the Christmas Day means for the westerners,the Spring Festival is the most important celebration for Chinese people.This big event according to Chinese traditional lunar calendar relaxes and pleases the whole country as the happiest gathering time of the year.National-wide crusade for going back home,too-difficult-to-get train tickets,generous family-going-out shopping,Miaohui laundering,New Year Eve reunion dinner,visiting friends and relatives,watching annual TV gala......each piece of clue reminds us of the smell of Chinese Spring Festival.  相似文献

FDI(Foreign Direct Investment),a component of a country's national financlal accounts,is investment of foreign assets into domestic structures,equipment,and organizations.It does not include foreign investment into the stock markets,concession and subcontract.FDI iS thought to be more useful to a country than investments in the equity of its companies because equity investments are potentially "hot money"which can leave at the first sign of trouble,whereas FDI is durable and generally useful whether things go well or badly.  相似文献
