基于动态模糊关系(DFR)的多Agent系统组合模型

多Agent系统面对复杂的、单个Agent难以胜任的问题时需要合作,由哪些Agent参与合作是其中一个关键问题,从Agent之间在合作中形成的关系出发,研究多Agent系统的动态模糊性,在此基础上借助动态模糊关系理论建立多Agent系统组合模型,以此为基础提供一种解决Agent合作问题的途径。     

On the No-arbitrage Principle and Option Pricing in a Fuzzy Market

Discuss the no-arbitrage principle in a fuzzy market and present a model for pricing an option. Get a fuzzy price for the contingent claim in a market involving fuzzy elements, whose level set can be seen as the possible price level interval with given belief degree. Use fuzzy densit） function and fuzzy mean as evidence for such model. Also give an example for comparing the result of the model in this article and that of another pricing method.     

基于模糊理论的人才双向选择问题应用软件

基于模糊集理论开发了一种人才双向选择应用软件，由该理论在［０，１］区间取值及隶属函数等概念，把模糊命题量化，在构造关系矩阵基础上，对其中每一元素用真值、导出置信度、综合真理值进行检验排出无效元素，经排序得出所需结果，实用结果表明，用Ｐｒｏｌｏｇ语言开发的应用软件运作的结果与人为的主观判断一致。     

A Fuzzy Neural Model for Face Recognition

Introduction1 Nowadays, biometric (e.g., face, finger print, iris, palm)identification is becoming more and more important [1] [2] and there are numerous commercial and law enforcement applications. Compared with other biometric identifications, face recognition has attracted more attention for its characteristics ofuser-friendly, intuitionistic and convenient. Much work hasbeen done on face recognition over the last 20 years. Generally speaking, face recognition is composed of three procedure…     

江苏省区域经济发展水平的静态评判

利用模糊数学和信息方法对江苏省区域经济发展水平的静态表现进行了综合评判.苏州、无锡为该省经济增长中心,南京为亚中心,淮阴、宿迁为不发达地区,梯度轴线为从太湖沿京杭大运河指向洪泽湖.     

一种新型的模糊PID控制器

文中将PID控制器在工程整定方法的基础上，对PID参数作归一化处理，然后通过模糊控制规则和模糊推理确定对PID的参数进行调节，提出了一种新型的模糊PID算法，从而使PID控制器具有适应非线性、时变，不确定性等复杂难控对象的能力。最后利用某火力发电厂过热气温为对象对该算法进行了仿真研究。结果表明该算法使用可靠、精度高，而且具有较强的抗干扰能力和鲁棒性。     

模糊问句与超命题逻辑

首先将问句数学化,然后探讨了问句中的模糊性,由此定义了模糊问句,进一步提出了一种超命题逻辑,借以研究模糊问句,获得了问句逻辑的若干数学解释.     

AGGREGATION OF FUZZY OPINIONS UNDER GROUP DECISION-MAKING BASED ON SIMILARITY AND DISTANCE

In this article,a new method for aggregating fuzzy individual opinions into a group consensusopinion is proposed.To obtain the aggregation weights of each individual opinion,a consistency indexof each expert with the other experts is introduced based on similarity and distance.The importance ofeach expert is also taken into consideration in the process of aggregation.Finally.a numerical exampleis presented to illustrate the efficiency of the procedure.     

牙轮钻机垂直振动分析及控制

从理论上分析了垂直振动的产生原因及其与钻进参数的关系。在此基础上，应用模糊控制理论，提出了垂直振动超限时改进的一维模糊控制方法及控制策略，并在牙钻机实验台上进行了控制实验。结果表明，当垂直振动超限时，该控制方法可使其迅速降至设定值附近；当垂直振动小于设定值很多时，钻进参数会自动提高，以保证钻进效率。
