查询词典 fuzzy theory

Based on grey system theory and fuzzy theory, uncertain decision making problems and several relative articles were studied, then points out the advantage and shortage of them when dealing with grey fuzzy set were pointed out. In this paper, using optimization theory and the maximum entropy formulism, a method for multi attribute group decision making based on the theory of grey fuzzy relation is established.

引言不确定型决策问题在社会、经济、环境和管理等各个领域中普遍存在，并且是一项复杂的系统工程，由于人的参与使相关数据与信息系统中的不确定性更加显著，不确定性通常分为 2类，一个是所谓"主观"不确定性，即人的思维模糊性，另一个是信息不完全、不充分所造成的客观不确定性，即灰性。

Fuzzy theory has been widely applied to AI. For example, fuzzy inference is based on fuzzy theory.

模糊理论在AI中的应用也是很广泛的，模糊推理就是基于模糊理论而实现的。

By using the technigue of pointwise representation, this paper goes somewhat deeper into the theory of fuzzy subspaces. It has mainly studied the structure of generated fuzzy subspaces, and various relations between a fuzzy set and its generated fuzzy subspace are given. Furthermore, a pointwise representation theorem for fuzzy subspaces is presented.

本文利用点态表示方法进一步探讨了Fuzzy子空间理论，着重研究了生成Fuzzy子空间的结构，给出了Fuzzy集与其生成Fuzzy子空间之间的各种关系，进而，文章还给出了Fuzzy子空间的一个点态表示定理。

The aim of this research was to propose an operating mechanism based on fuzzy theory to integrate scores of multiple assessments. The character of fuzzy theory was to process information vaguely, imprecisely, and uncertainly.

本研究旨在利用模糊理论符合人类语意描述与思考逻辑之特性，舍弃线性且绝对性的传统分数处理方式，改以非线性的模糊逻辑推理方式，发展一个整合多元评量分数的运算机制，经由该机制所运算所得的结果研究者称其为"模糊复合分数(fuzzy composite score，FCS)"，而该机制则称其为"FCS评分架构"。

The present study applied fuzzy theory and Fuzzy MCDM to build a strategy which utilizes Fuzzy MCDM for accessory negotiation. This strategy calculated every accessory's fuzzy evaluation and negotiation insistency for selection and negotiation. At last, a shopping website with the function of accessory negotiation was built on the Internet in the expectation that it can make progress in both buyers' satisfaction and sellers' earnings.

因此本研究运用模糊理论与Fuzzy MCDM的机制与方法，建立Fuzzy MCDM为附属品的协商机制之策略，计算出各附属品的模糊评估值与协商坚持度，以为遴选之依据与协商之准则；最后在网路上实作建置一个具有协商附属品功能的购物网站，藉由系统的建立期能获取消费者满意度且成就商家的营业收入之双重利基。

The semigroup algebra theory,which has a huge development under interior and exterior double Mathematical conditions form 1950"s to 1960"s,is a new branch of algebra theory.In 1990,R.Biswas gave definition of anti-fuzzy subgroup.In 1995,Shen gave definitions of anti-fuzzy subgroup and normal anti-fiizzy subgroup of group.

半群的代数理论是在数学内部和外部双重条件下，从20世纪50年代到60年代发展起来的一个崭新的代数分支。1990年，Biswas R提出了反Fuzzy子群的定义；1995年沈正维提出了一个群的反Fuzzy子群和正规反Fuzzy子群的定义。

On account of the traffic flow with the high complexity and randomicity, we could adopt fuzzy theory and fuzzy control technology without setting up an accurate math model, which can avoid the unideal control effect, brought by inaccurate math model, and also can adapt the real-time control. Therefore, this paper applies the fuzzy theory and fuzzy control technology to research and discuss traffic control.

因为，交叉路口交通流的运行具有高度复杂性和随机性的特点，采用模糊理论和模糊控制技术，可以不需要建立精确的数学模型，这样既可以避免由于被控对象数学模型建立的不准确而导致控制效果不理想，又能够适应交叉路口的实时控制要求。

Fuzzy sets and rough sets are means handling on fuzzy and indetermination. Today, fuzzy set theory, and rough set theory are combined in mathematics, and the combination is been adverted more and more by international academy.

二者是处理Fuzzy性和不确定性的数学工具，将二者结合起来研究，近年来越来越受到国际学术界的关注。

Meanwhile, there exists quite a number of information that is fuzzy but can not be expressed and processed by fuzzy sets theory in the real world. To settle the shortage of Fuzzy Sets theory, W.L.

与此同时，现实世界中，相当一部分具有模糊性的信息是Fuzzy集理论无法表示和处理的，台湾学者W.L。

The Fuzzy-PID controller of fin stabilizer was designed based on fuzzy control and PID control theory. The controller of Fin Stabilizer is designed which uses roll angle and angular velocity of roll angel as input and fin angel as output. The model of ship is built based on Conolly theory. The controller is simulated using MATLAB. Results shows that compared with conventional PID controller, the FUZZY-PID controller has better effect.

设计了基于模糊控制和PID控制理论的FUZZY-PID复合控制减摇鳍控制系统，以横摇角和横摇角速度为输入量，鳍角为输出量，基于Conolly理论建立了船舶模型，利用MATLAB针对不同海情对控制器进行了仿真，结果表明减摇鳍模糊控制器动态响应性能和稳态控制精度均十分理想，能够满足减摇鳍控制系统的控制要求。
