编组站有列车工厂之称,其作业效率影响因素众多,然而在对编组站作业效率的分析研究中,并非用到的效率属性越多对其分析效果就越好,因为不同效率属性可能存在重复和冗余。本文针对编组站效率目前研究的局限性,基于粗糙集知识约简的理论,根据编组站效率评价问题的特点,给出了相应的决策信息系统,并运用正域约简的方法,用MATLAB与MuPAD实现了粗糙集理论在编组站作业效率评价研究中的应用,证明了方法的可行性和适用性。
The marshalling yard has the name of a train factory, and its operation efficiency has many influencing factors. However, in the analysis and study of marshalling yard operation efficiency, the more unused efficiency attributes are better for the analysis effect because different efficiency attributes may repeat And redundancy. Based on the theory of rough set knowledge reduction, according to the characteristics of Marshalling Station efficiency evaluation, this paper presents the corresponding decision-making information system and uses the method of positive domain reduction, using MATLAB and MuPAD realizes the application of rough set theory in marshalling station operation efficiency evaluation and proves the feasibility and applicability of the method.
