At present, the project success rate is generally far from satisfaction in China and overseas, in the meanwhile, the losses and wastes of projects are serious. One of the reasons for them is that knowledge management is not applied or improperly applied in the project management. In this paper, the different classifications of knowledge and expression patterns in project management were reviewed so that the useful knowledge could be extracted from the project database and be reused in other projects. After the analysis about various models of Knowledge Discovery in Database (KDD), the model of KDD based on Multiple Criteria Linear Programming (MCLP) was established, to which Text Mining and Data Mining were applied. With the application of this model, the required patterns of project knowledge were discovered from the project databases, which could be reused in the current project. Finally, the problems of the application of the model were discussed in detail.
目前,国内外项目成功率普遍不理想,同时项目损失和浪费严重。其原因之一是在项目管理中没有应用知识管理或应用不当。本文综述了项目管理中知识的不同分类和表达方式,以便从项目数据库中提取有用的知识,并在其他项目中重用。在分析各种数据库知识发现模型的基础上,建立了基于多准则线性规划(MCLP)的数据库知识发现模型,并将文本挖掘和数据挖掘技术应用到该模型中。通过该模型的应用,可以从项目数据库中发现项目知识所需的模式,这些模式可以在当前项目中重用。最后,对模型应用中存在的问题进行了详细讨论。

Through incorporating the effect of the distributed endeavor on demand and return ratio into the three-stage perishable product's supply chain, the game models linking the buyer's return and manufacturer and distributor's reclaim are established under uncertain environment. The paper points out the supply chain can't coordinate under the contract not being concluded among manufacturer, distributor and retailer, but the supply chain can coordinate through reclaim the return and remnant products based on rebate and penalty policy.
通过将分布式努力对需求和退货率的影响纳入到三期易腐产品供应链中,建立了不确定环境下买方退货与制造商和分销商退货的博弈模型。指出在制造商、分销商和零售商之间没有签订合同的情况下,供应链无法协调,而在回扣和惩罚政策的基础上,供应链可以通过回收退货和剩余产品来协调。

Based on a review of indicators for compiling the existing city planning guidelines in China, this study proposes the concept of people-oriented residential environment can be evaluated by indices of livability in a quantitative way. The study adopts theories and methods of grey system, and tentatively establishes a model for such quantification. Data obtained from real cases are used to test the model, with results showing this method has advantages of simple calculation, high resolution, and cost-effective by using large amount of existing indicators of city planning guidelines. Compared to the existing mechanism which is largely based on experiences, this method is more objective and reliable.

Rural human capital engineering: theoretical basis, conceptual models and policy direction for the “ARF” problems in China 农村人力资本工程:中国“ARF”问题的理论基础、概念模型与政策方向
Pub Date : 2007-11-01 DOI: 10.1109/GSIS.2007.4443512

This paper analyzes the necessity of implementing rural human capital engineering from the perspective of practical demands firstly. Then it points out the theory vacancy of this area by going through the literatures, and the theoretical basis of the topic is therefore located. In this way, the topic of rural human capital engineering is brought forth from both perspectives of practical necessity and theory evolution. After that, it illustrates the logic and conceptual framework for solving the problems of "ARF" (agriculture, rural land, farmers) in China. In the light of this framework, we come to the conclusion that the key to the "ARF" (agriculture, rural land, farmers) problems is improving the farmers' diathesis (i.e. the reserve and flux of rural human capital), and implementing rural human capital engineering. Using system engineering theory and strategy management theory, this paper finally formulates a four-dimensional systematic model to resolve the "ARF" problems. This paper holds that it is a systematic circle including strategy selection, strategy planning (formulation), strategy implementation, strategy control, strategy assessment, and strategy feedback. It establishes the rural human capital engineering system comprehensively from the following four sub-systems: rural human capital investment system, rural human capital financing system, the transfer and flowage of rural labors, and rural education investment & social security system.
本文首先从现实需求的角度分析了实施农村人力资本工程的必要性。然后通过对文献的梳理,指出了该领域的理论空白,从而定位了课题的理论基础。这样,农村人力资本工程这一课题就从实践的必要性和理论的演进两个角度提出了。然后,阐述了解决中国“农业、农村土地、农民”问题的逻辑和概念框架。在此框架下,我们认为解决“三农”问题的关键在于提高农民素质(即农村人力资本的储备和流动),实施农村人力资本工程。运用系统工程理论和战略管理理论,构建了解决“ARF”问题的四维系统模型。本文认为战略选择、战略规划(制定)、战略实施、战略控制、战略评估、战略反馈是一个系统的循环。从农村人力资本投资体系、农村人力资本融资体系、农村劳动力转移与流动体系、农村教育投资与社会保障体系四个子系统全面构建农村人力资本工程体系。

The analysis object of this paper is the six provinces and one municipality in East China, and the research method which is adopted is grey relational analysis. The research result shows that for the influence of scientific and technical output indexes, the greatest is both "expenditures for scientific and technological activities" and "R&D expenditures". The next is "scientists and engineers," and the lowest is "persons engaged in scientific and technological activities." The two indexes of less influence belong to the input of financial resources, and the two indexes of more affection are part of the input of manpower. Through the grey appraisement of sixteen and four indexes, we can find out the same conclusion: the regional scientific and technical productive efficiency of Shanghai is the highest; Jiangsu is the second; Fujian is the third; Zhejiang is the 4th; Anhui is the 5th; Shandong is the 6th; and the final one is Jiangxi. Further research suggests that when carrying on the analysis of scientific and technical efficiency, compared with sixteen indexes, the selected four indexes may be enough.
本文的分析对象为华东六省一市,研究方法为灰色关联分析。研究结果表明,对科技产出指标的影响最大的是“科技活动支出”和“研发支出”。其次是“科学家和工程师”,最低的是“从事科学技术活动的人”。影响力较小的两个指标属于财力投入,影响力较大的两个指标属于人力投入。通过对16项指标和4项指标的灰色评价,可以得出相同的结论:上海的区域科技生产效率最高;江苏第二;福建位居第三;浙江排名第四;安徽第五;山东排名第六;最后一个是江西。进一步的研究表明,在进行科技效率分析时,与16个指标相比,选取的4个指标可能是足够的。

The irreversibility effect of evacuation decision is considered during emergency response. The evacuation decision process can be divided into several periods. The time attribute of grey situation decision is discussed. A framework for a multiple periods of flood disaster evacuation grey decision model is presented. This model approaches the evacuation decision problem by grey decision method and takes into account of the potential flood damage, rate of fatalities and evacuation effect index. The optimal decision (evacuation, no evacuation) is based on minimization of the total expected costs, minimizes the rate of fatalities. The model is tested for evacuation decision of river floods in Netherlands 1995, and the conclusion is in accordance with the result of probabilistic evacuation decision model put forward by Brian Frieser.
在应急响应中考虑了疏散决策的不可逆性。疏散决策过程可分为几个阶段。讨论了灰色态势决策的时间属性。提出了一种多时期洪水灾害疏散灰色决策模型的框架。该模型采用灰色决策方法,综合考虑潜在洪涝灾害、死亡率和疏散效果指标,对疏散决策问题进行求解。最优决策(疏散,不疏散)是基于总预期成本的最小化,使死亡率最小化。通过对荷兰1995年河流洪水疏散决策的检验,所得结论与Brian Frieser提出的概率疏散决策模型的结果一致。
