在实例研究中，针对制定客运专线和既有线综合运用方案的要求，进行了旅客需求调查，对调查数据做了深入的分析与挖掘，并提出了很多有价值的建议，特别是通过调查旅客支付意愿，为客运专线定价提供了参考。

This paper presents a N-R method of acquiring multi-level reasoning production rules automatically based on NN, so as to resolve the bottle neckproblem in building a knowledge - based system-knowledge acquisition. This methodadopts a characteristic NN structure model and corresponding learning algorithm, so thatN -R method can fix the number of hidden nodes dynamically and form new conceptswhich are not defined in the sample set in the course of learning. Having been trained, NNis transforme...

本文为解决知识系统构造过程中的瓶颈问题──知识获取，提出了一种基于神经网络NN的自动获取多级推理产生式规则的N－R方法，该方法采用了特有的NN结构模型和相应的学习算法，使得NN在学习过程中动态确定隐层节点数的同时，也产生了样例集中没有定义的新概念，学习后的NN能用本文提出的转换算法转换成推理网络，最终方便地得到产生式规则集

The performance capability of DOCSIS compliant architectures is dependent upon the headend scheduling algorithms which are not specified in the specifications. Therefore, it is important to establish a set of reference performance characteristics for the most simple of scheduling algorithms against which more complex algorithms can be compared. A prioritized FCFS scheduling algorithm is adopted in this paper.

即使对于严格要求的实时CBR业务的延时性能，采用抢占优先级的服务策略所能提供的性能也大大好于业务所要求的性能，这就为进一步提高非实时数据业务的延时性能提供了机会，有可能采用适当的调度策略在满足实时CBR业务的延时性能的基础上，提高非实时数据业务的延时性能。

To avoid the collision accidents of ships at sea, with the universalizing and application of computer, and the development and maturity of the technology of Expert System and Artificial Intelligent, this paper developed an intelligent collision avoidance expert system for navigation. The main research work centers on several aspects, which will be represented as below:By the navigation rules" understanding and analyzing, and by the navigation experience and navigation samples" collecting and trimming, we put forth and build a multi-unit and layering KB systematic structure, and implement the KBM. According to features of different knowledge, we adopt multifarious KR, such as: frame KR, production rule KR, procedure KR. We also build a multi-inference system, which based on analog inference, forward illation inference, conversion inference and meta-rule inference. At the same time, we develop each reasoning algorithm. For some problems in collision avoidance region during the building of the expert system, we put forth and build a set of models to solve them using neural network technology.
