由路局计统处、上海铁路科技开发公司共同开发的“货运精密统计数据共享系统”采用符合国际通用的标准和规范,采用了先进的网络技术、数据库技术和全信息的数据采集手段。系统具有闭环自审计技术,能自动验证系统程序和数据的正确性。首创了径路描述语言和稀疏尾链追踪经由算法及利用数学模型完成违流数据的清洗、过滤和调整, The “Freight Precision Statistical Data Sharing System” jointly developed by the Bureau of Railway Administration and the Shanghai Railway Science and Technology Development Company adopts internationally accepted standards and norms and adopts advanced network technology, database technology and all-information data collection means. The system has closed-loop self-audit technology, which can automatically verify the correctness of system programs and data. Pioneered the path description language and sparse trailing tracking through the algorithm and the use of mathematical models to complete the data flow of cleaning, filtering and adjustment,
