元数据在煤矿机械加工时间定额计算中的应用研究

Applied Research on Metadata Used for Machining Time-quota Calculation of Coal Mine Machinery

通过研究煤矿机械生产中的加工时间定额算法,提出采用元数据描述时间定额算法的方案,实现了各加工步骤时间定额的自动计算。元数据以XML格式保存,其中包含加工步骤、加工方法、计算公式及参数值表的定义。用户可以在不编程的情况下通过元数据来使用和管理定额算法。

By researching the algorithm of machining time-quota in producing coal mine machinery, bring forward a way to describe the algorithm by metadata, achieve the purpose of calculating machining time-quota in each processing steps. The metadata is saved in XML format, and the definition of processing steps, processing methods, formulas, list of parameter values contains in it. Users can use and manage the algorithm of machining time-quota through metadata instead of programming.
