Therefore , many researches have been developed to deal with it . the hierarchical fuzzy system , proposed provides a way to deal with this problem . the hierarchical fuzzy system consists of a number of low - dimensional fuzzy systems connected in a hierarchical fashion 对于这个问题，有很多解决方案， “递阶模糊系统” ，顾名思义，就是以递阶的形式表示，将几个低维数模糊系统相连接，从而达到大大减少规则库内规则数量的问题。
In design of the filter rules , it takes the rules as a set of cuboids , and the searching process is transferred to a process of locating a point in these cuboids . with help of reference to some documents in geometry , it gave methods to solve of the problem 在过滤规则库的搜索过程中，本文将规则库视为一个三维空间中有重叠的长方体集合，在规则库中搜索数据包匹配的规则，则转化为在长方体集合中搜索点所处的长方体的问题。
According to the analyzing results upwards , the author completed trajectory plan for the moving platform , analyzed conditions avoiding obstacles when the robot is moving , and completed trajectory plan for the mechanical arm based on joint - space and descartes - space according robot ’ s assignments 机械臂的运动学和动力学分析之后,对全方位轮式移动机构进行了定位分析,建立运动模型和基本动作规则库,并对全方位轮式移动机构进行路径规划。
Then employing neural networks learning techniques , fuzzy logic rules , input - output fuzzy membership functions and weights in networks can be easily tuned . so rule matching is reduced , inference process is accelerated , adaptability of the system is greatly improved 再利用神经网络学习能力便很容易修改规则库中的模糊规则以及隶属函数和网络权值等参数，这样大大减少了规则匹配过程，加快了推理速度，从而极大程度地提高了系统的自适应能力。
According to the characteristic of the local electric net , this paper connects expert system with microsoft vc + + by using oop technique . and it designs the rule - base which is classed and graded . it achieves intelligent setting of the protection based on the reformative expert system 本文结合地方电网的实际特点，利用面向对象的技术将专家系统与vc + +结合，设计了基于对象的分类分级管理的规则库，从而实现了改进专家系统的继电保护智能整定计算。
According to a great deal of knowledge and experience in actual production , and through the analysis and concluding of theory , the model of fuzzy knowledge and rule base of expert system is constructed by applying fuzzy technology and heuristic rule , as well as knowledge learning mechanism 该系统以实际生产中积累的大量知识和经验为依据，通过理论分析和归纳，基于模糊技术和产生式规则建立了专家系统的模糊知识规则库模型，并建立了知识学习机制。
The main subjects of this paper are as follows : ( 1 ) the conditions of map use , characters of map regions and map scale are considered during map generalization . we also build several tools to dynamic sum up and pack up generalization rules and parameters and put them to generalization knowledge library 考虑了影响制图综合的三要素，即地图用途、制图区域地理特点和地图比例尺，并实现了对综合规则、参数的归纳和整理，建成了可动态扩展的规则库和参数库。
