Augmented reality system for aiding engineering design process of machinery systems

The paper presents the application of augmented reality for aiding product design and development of machinery systems.Augmented reality technology integrates an interactive computer-generated word with an interactive real word in such a way that they appear as one environment.AR technology can enhance a user's perception of the real world with information that is not actually part of the scene but is relevant to the user's present activity.Presented in the AR system is a mode for changing views of data-...     

基于知识的银行贷款分类系统

文章主要探讨了基于知识的专家系统 ( KBS)在银行贷款分类方面的应用 ,银行信贷人员藉此可以决定在何种情况下批准贷款 ,从而定性地分析了影响贷款的风险程度 ,它与财务分析相互印证、相互补充 ,为贷款分类结果提供充分和必要的依据。文章还讨论了基于知识专家系统的知识库、数据库、推理机、解释器及知识获取 5个组成部分     

基于信息熵的ID3分类算法的研究

ID3分类算法无法处理连续性数据并且在选择分裂属性时明显倾向于取值多的属性，无法产生准确的规则。基于信息熵的连续数据离散化预处理技术有效地拓展了ID3算法的应用领域，并提出了基于信息增益率的分裂属性选择方法，样例数据测试结果分析表明：该分类算法改正了在选择分裂属性时明显倾向于取值多的属性的缺陷，提高了分类的精度。

基于前景理论的决策模型研究

现有的决策模型大都建立在预期效用理论的基础上,这是一种纯粹理性的决策方式.但人并不总是完全理性的.采用前景理论代替期望效用理论作为决策模型,它更符合人类实际的决策模式,尤其是在战场这种急剧复杂和动态的环境中.首先对前景理论的提出进行了介绍,并与预期效用理论进行了对比,然后结合一个案例对前景理论在决策行为建模中的应用方式进行了研究.最后对前景理论应用于作战决策研究时的特点和过程进行了说明.

Systemic Thinking in China: A Meta-Decision-Making Bridge to Western Concepts

We use a meta-decision-making approach to show that parallels can be drawn between an Oriental systems methodology, wuli, shili, renli (WSR), and the adjusting, convincing, and committing dimensions in nomology, a generic metamodel that is based in decision science. We then use the match between them to propose a metalinguistic bridge between China and the West that could aid in the communication and sharing of systems experiences. We use the bridge to consider some of the interpretations of Chinese systems experiences in terms of Western models in a special issue of Systemic Practice and Action Research (Vol. 13, No. 1, 2000) on systemic thinking in China. We show how WSR could help to relate these interpretations in terms of Chinese concepts. We explore proposals in a paper in the special issue by Midgley et al. (2000) about how to operationalize human relations in Chinese systems practice. We show that these correspond to a suggestion that developing commitment within a systems project should be done in a convincing manner. Hence, in WSR terms, we would say that their advice could be interpreted as meaning that shili should be used to operationalize renli. Finally, we propose as a research agenda that the bridge be used to explore how Chinese insights could help to illuminate Western systems experience.
