Learning Causality Diagram Structure Based on Genetic Algorithm

The Causality Diagram theory,which adopted graphical expression of knowledge and direct causality intensity of causality,overcomes some shortages in Belief Network and has evolved into a mixed causality diagram methodology coped with discrete and continuous variable.But it is difficult that the structure of Causality Diagram given by expert.Because the complexity of causality diagram structure goes up exponentially through the number of the vertex's increasing,it is NP-hard problem to find the most possible structure from a set of data.The authors discuss approaches and present Genetic Algorithm,to find the most possible structure from a set of data.Experiment shows the method is effective.

On the Development of Urban Spatial Structure in the Information Age

Today the information globalization is the trend of society development. The information technology has great influence not only on the mode of life and production, but also on the urban social and economic structure. In order to fit in with the change in this regard, the urban land-use distribution, residential mode, traffic pattern and so on should be changed correspondingly. Therefore, this change will lead to the development and evolution of whole urban spatial structure. In this paper, the development tendency of urban spatial structure in the information age is analyzed and some proposals on city planning and construction are put forward.

基于信息熵的庄浪县土地利用结构变化及其驱动力分析

为研究庄浪县土地利用结构动态变化情况,促进土地资源的合理利用和可持续发展,基于庄浪县1997—2012年土地利用变更数据以及经济社会统计数据,采用信息熵、均衡度和优势度原理,分析庄浪县土地利用结构的动态演变特征,并运用主成分分析方法对影响庄浪县土地利用结构动态演变的驱动力进行分析。结果表明：1997—2012年,庄浪县土地利用结构信息熵总体呈先上升后下降再上升的波浪式趋势变化,表明各区域的土地利用系统仍处于较大程度的开发中。耕地、林地及未利用地面积所占比例的高低,是影响庄浪县土地利用结构信息熵的主要因素。人口经济发展状况、城市化、产业结构是庄浪县土地利用结构变化的主要驱动力。     

基于信息熵的农民信贷需求研究

以信息熵理论为基础,通过构建农民信贷决策的信息熵函数,以华北平原地区农村为例,探求了信息熵对农民家庭收入和支出两方面的影响及其对农民信贷需求的影响。研究发现,信息对农民家庭收支的影响存在差异;由于农村信息传播不畅通,致使农民家庭信贷需求是不完全有效的,并指出建立完善的农村信息传播机制,是提高农民信贷需求有效性的重要途径。

The responsibility of CIO and information center is also discussed. The organization structure presented in this paper is useful to the enterprise in china.     

Model of Information Integrating in CIMS Based on the Object-oriented Method

Information integrating is the most important key to CIMS,which is the base of the function integrating and all others.Because of so many kinds,so complicated structure,so many different sources and uses that the information in CIMS has,it is necessary to build a popular Information Integrating Model. The model of information integrating in the thesis bases on the enterprise model,which is presented by ISO(International Organization for Standardization).According to the object-oriented method,the process of modeling begins with classifying the information,and then describes the definition of the attributes and the structural relation of those objects. By means of the idea of Encapsulation and Inheritance,the destination of information integrating can be arrive and the model of information integrating can be set up. The model which is based on the share information is helpful to finish the function integrating and the whole CIMS' construction. Moreover,the system which is developed following such program can be reused for many times and the developing circle of CIMS can be apparently shortened,too.
