To study the customer behavior by carrying out Customer Relationship Management in enterprises, we use some relative technology and method of decision tree of data mining to propose a kind of UPTree algorithm of data Mining, which is used to mine a great deal of information hidden in customer behavior.

为了解决在企业中实施客户关系管理，CRM系统中客户行为的定量研究问题，利用决策树的数据挖掘相关技术和方法，提出了UPTree数据挖掘算法，并采用UPTree算法对隐藏在大量客户行为中的信息进行挖掘，从而获取了CRM系统中潜在的客户行为规则，并给出这些行为规则的IF-THEN的描述形式，为企业的科学决策提供依据。

Through simulation and computation, some critical values to contral interferences are obtained. These values have directive significance to the design and deployment of WRAN.(4) New methods to measure and analyze spectrum aredevelopedAccording to the shortages of previous spectrum measurements, new methods to measure spectrum occupancy in wide-band and multi-point synchronously is proposed in this dissertation, and the tests last a whole week; the relativities of licensed services are considered when test points are selected. More importantly, data mining and in-depth analysis are carried out with the huge amounts of test data, and a channel analysis method using Channel Vacancy Duration and Service Congestion Rate are proposed. The spectrum relativities of 3-dimension in time, space and frequency are researched also. The correlativity between channel state and history information is discoved, and which will provide the scientific basis to channel modeling, spectrum analysis and decision of CR users.
