知识管理是指通过对知识资源进行开发和有效利用,运用集体的智力知识提高社会的应变和创造能力,进而产生广泛效益的管理活动.知识可分为显性知识和隐性知识.显性知识是一种形式化的知识,经过编码后可以通过语言、文字、图表等形式表达出来,并可以方便地通过计算机进行整理和存储;隐性知识是一种难以形式化的知识,是个人经验的结晶,存储于个人的脑海里,难以交流和掌握. 相似文献

海军水下无人作战系统因其造价低廉、隐蔽性强、避免人员伤亡等诸多优点而得到大力发展,美国等国已制定各类水下无人作战系统发展规划并开发出便携型、轻型、重型和巨型等多种水下无人作战系统,并向着提高智能化、模块化和标准化程度、拓展多平台搭载使用能力等方向发展。为了应对威胁,我国也应从顶层规划水下无人作战体系发展路线,开发多样化的水下无人作战系统。 相似文献

Fleet deployment optimization models.Part 2 总被引:1,自引:0,他引:1
The fleet deployment problem for the one origin,one destination fixed-price contract requiring the transport of a given total amount of cargo within a given period is formulated and solved for the case that one or more cost components are given staircase functions of time. A computer program has been developed to implement the solution of this problem. The fleet deployment problem with one or more costs being random variables with known probability density functions is also formulated. Analytical expressions for hte basic probabilistic quantities, i.e the probability density function,the mean and the variance of the total operating cost, are presented. Finally, sample results are presented and discussed and some extensions for further research are suggested. 相似文献

10CrNi3MoV船用钢热成形的力学行为与性能研究 总被引:2,自引:2,他引:0
高强度船用钢热成形时,由于加热与淬火的交互作用,形成渐变微观结构。研究表明,渐变微观结构使得材料的硬度、强度从里到表依次降低,延展性依次增加,较平缓的冲击力水平及材料的逐层失效使结构保持较高的吸能能力;具有较小的变形抗力、塑性好、成形极限高,而且成形零件的精度和强度较高。渐变微观结构综合了各单相材料的优秀性能,适合用于承受冲击吸能的构件。 相似文献

Despite the prevalence of its use, very little is understood about the role of electronic commerce (EC) practice on the strategic management of container shipping companies. Four case studies were undertaken to assess the main uses, motivations, barriers and strategic relevance of EC in the container shipping industry between 1992 and 2002. The cases studies included one large, one medium and one small deep-sea container line, and one medium-sized feeder line. The research found that despite pressing technical and managerial barriers, the need to improve internal economies provided the most fertile grounds for EC use in 1992 and EC was seen as a tactical tool to achieve these goals. By 2002, customer-oriented motivations became critical to the increased relevance of EC and to its perception as a business necessity. 相似文献
