在分析一种非线性数据处理新方法的核心概念基础上‚研究了基于一类分类方法的多类分类基本原理‚提出了应用于多类分类的可信度函数‚使聚类与分类的结果更具有可信度．最后‚以某企业对供应商关系的调查数据为例‚将这种方法应用于企业商业关系网络分析中．结果表明了该方法的有效性．

 Relationship management is the key to the success of a modern firm．As a new method to process the nonlinear data‚the Kernel method provides a feasible scheme to analyze the complex relationship networks in firms．In this paper‚based on the analysis of the core concepts in the Kernel method‚the basic principles of the multiclass classification based on the one-class classification were studied‚and the reliability function applied to the multiclass classification was put forward‚which makes the classification results more reliable．Finally‚the method was applied to the data analysis of the relationships between a firm and its suppliers．The results reveal the validity of the proposed classification method．
