铁路局运输指标灵巧统计的研究

Study on smart statistics of transport indexes in railway administrations

分析一般铁路局装车指标统计系统在灵活性方面的不足,需要引进灵巧统计概念。介绍灵巧统计索引文件、装车站集合、统计指标集合及统计结果输出等实现方法,在此基础上实现灵巧统计算法,并给出实例。得到结论是:对于临时性的统计要求,仅需修改column(.)函数及维护灵巧统计索引文件便可实现上述要求,极大减少新编程序量。

It was analyzed the disadvantage of Ordinary Statistics System for railway administration loading indexes, introduced the concept of smart statistics. It was concentrated on the realization of smart statistics index file, loading station set, statistics index set and the output of statistics results. On the above basis, the smart statistic algorithm was introduced, and an example was also available in the paper. Finally it was come to a conclusion that for a temporary statistics requirement, you had to only modify function column（.） and maintain the smart statistics index file to meet the requirement, thus it was greatly reduced the amount of new program necessary.
