通过分析归纳有关铁路客票的计价文件 ,广泛调查研究铁路客运需要 ,分别给出了铁路客票的普通票、通票、中转票票价的数学表达式 ,并设计了存储票价数学表达式中各因素的基础计价数据与计价参数的组织方案、计价数据复制方案 ,以及计算机计价程序 ,由此构成全国铁路客票计算机联网售票的计价系统。计价数据由铁道部中心数据库统一管理并复制到其它数据库。铁路客运使用情况表明 ,计价系统计算票价正确、运算迅速、具有良好的数据一致性和广泛的适应性、维护方便 ,满足了全国铁路客票计价的各项要求。
By analyzing and summarizing the pricing documents about railway tickets, the paper makes extensive investigations and studies on the needs of railway passenger transportation, and gives the mathematical expressions of ordinary ticket, pass ticket and transit ticket fare of railway ticket respectively, and designs the factors of mathematical expression of stored fare The basis of pricing data and pricing parameters of the organization of programs, pricing data replication programs, and computer pricing procedures, which constitute the national railway ticket computer network ticketing pricing system. Price data from the Ministry of Railways central database unified management and copy to other databases. The use of railway passenger transport shows that the pricing system calculates the fares correctly and operates rapidly with good data consistency and wide adaptability and convenient maintenance, meeting the requirements of national railway ticket pricing.
