Application of modeling and decision tree in railway system

摘要

Constructing access and operating model on train ticket data is an important task for China Railway Train Ticket System (CRTTS). This paper proposes a new fundamental structure for the data lifecycle so that assembly sharable information model for concurrent design, and access process can be built. It includes a concept data model that establish feature mapping multiple relations for design domain, and a scalable, dynamic algorithm based on decision tree for characteristic expression. Applications suggest that the techniques combination can make the analysis on train ticket data perfect efficiency.
