  • 简介:尽管关于在组织的知识管理(千米;公里)的实现的许多理论被建议了并且学习,没有合并企业过程,大多数应用趋于独自站。知识的不同范畴提供不同好处并且当一种有效千米;公里方式仍然保持战略上重要,并且还仍然是understudied,怎么把千米;公里的各种各样的范畴集成到一条混合途径。因此,在这糊为新服务开发(NSD)和结果的测量集成主要千米;公里应用程序的一个混合模型金融好处被开发了。建议千米;公里模型合并新闻组,知识论坛,知识财产管理和一个混血儿为沿着二轴分享组织上的知识意味着的知识应用程序进程,明确对含蓄、单个对集体。在台湾的最大的管理咨询公司之一,中国,其过程NSD当模特儿,用千米;公里应用程序独自正在站,为案例研究被选择。一套混合千米;公里进程被开发实现建议千米;公里模型,并且它为把混合千米;公里惯例集成到企业进程与更大的金融好处说明一个应用程序。把确认基于增加的知识价值(KVA),建议千米;公里模型为在一个组织以内分享NSD知识提供一个新操作系统。通过由测量完成的金融结果的案例研究,建议千米;公里模型被发现向一个独占的混合平台提供一个实验进程模型在一个组织以内探讨创新途径和千米;公里的实际的值。

  • 简介:在知识管理系统(KMS)解决这些问题例如信息分享,扩大的能力和re-engineer,和在分布式、异构的环境的遗产系统的可重用的能力。这篇文章基于设计KMS的代理人和本体论介绍一个方法。这个方法由二个机构组成。一个人是有支持知识管理过程的三个代理人的知识机构。其它是有支持知识申请的三个代理人的申请机构。在这个方法,本体论被用来在在代理人之中交换的消息在知识库和内容代表知识。表明这个方法的优点,实验被执行了,结果暗示这个方法为小、中等尺寸的企业有效、有效设计KMS。
