中文摘要：
为了更好地测评石化企业生产执行系统（MES）软件的物料平衡模块数据校正功能,提出了一种基于仿真的数据校正结果的测评方法。该方法通过搭建仿真模型产生全厂物流过程的真值,并应用动态数据驱动方法进行模型参数的修正,即通过向仿真真值添加测量误差生成误差可配置的测量值,模拟现场真实的测量网络;应用物料平衡系统及其内嵌数据协调算法对测量值进行数据校正得到校正值,将校正值分别与仿真真值、测量值进行对比,定量评估数据协调算法的性能。相对于仅比较校正值和测量值的原评定方法,该方法能更加精确、全面地测评数据校正算法的效果,并在某石化企业的案例中得到验证。
英文摘要：
In order to better evalute the results of data correction function of material balance module of MES software in petrochemical enterprises, the evaluation method based on simulation for data correction results is proposed. The true values of the material processes in the whole plant are generated through establishing simulation model, and the correction of model parameters is conducted by applying dynamic driving method. Specifically, through adding measurement error on simulation true value to generate measurement with configurable error, the on-site true measurement network is emulated, by using material balance system and its embedded data coordinate algorithm, the data correction is implemented to obtain corrected value. The corrected value and emulated true value, and measurement are respectively compared to evalute the performance of data coordinate algorithm quantitatively. This method is more accurate than original evaluating method; it evaluates the effects of data correction algorithm comprehensively, and is verified in cases of certain petrochemical enterprise.
