Research on Interaction Effect of Whole Life Cycle Cost Elements of Rail Transit System Based on FP-growth Algorithm

轨道交通系统全生命周期投资大、建设周期长、成本要素众多且关联关系复杂。文章以安全域为边界,对轨道交通系统全生命周期总成本基于安全域、性能域、环境域进行分类,设计了一种改进的FP-growth算法,对各域成本要素之间的关联关系展开研究分析,通过带入实际数据,利用基于FP-growth算法的轨道交通系统全生命周期多域成本要素交互影响研究模型,来分析各域之间的交互影响规律。

The rail transit system has a large life cycle investment,a long construction period,numerous cost factors and complex relationship.This paper classified the total life cycle cost of rail transit system based on security domain,security domain,performance domain and environment domain.An improved FP-growth algorithm was designed to analyze the relationship between cost components in each domain.By introducing the actual data,the FP-growth algorithm-based rail transit system full life cycle multi-domain cost element interaction research model was used to analyze the interaction law between domains.
