基于粗糙集理论的纸币清分机配置规则获取方法研究

摘要

纸币清分机是一种光机电一体化的金融机具。针对不同的客户要求，对纸币清分机属性配置流程进行了概要分析。提出了一种基于粗糙集理论的纸币清分机配置规则的获取方法，实现了对决策系统的约简，使销售人员和客户可以尽快熟悉相应的配置规则。基于粗糙集理论进行知识模型的发现，设定条件属性和决策属性，最终根据实例数据形成配置决策表，利用Skowron 差别矩阵进行属性约简及核的提取。配置结果验证了所提方法的可行性和有效性。%Currency sorter is an optical,mechanical and electrical financial equipment.For different needs of customers,the workflow of currency sorter configuration is analyzed.On the basis of rough set theory,an acquirement method of currency sorter configuration rules is proposed.Through the reduction of decision-making system, marketing engineers and customers are familiar with the configuration rules as soon as possible.The rough set theory is used to realize the knowledge model discovery, the condition attributes and decision attributes extraction,eventually forming the configuration decision table according to the sample data.The Skowron difference matrix is used to obtain the attributes reduction and cores calculation.The configuration results demonstrate the feasibility and effectiveness of the proposed method.
