Material-flow Modeling Technology and Its Application in Manufacturing Execution Systems of Petrochemical Industry

材料流动的管理和控制形成在石油化学工业生产执行系统(MES ) 的核心。在 MES 的申请的瓶颈是与生产过程匹配材料流动模型的能力。一个动态材料流动模型在石油化学工业在生产过程的材料流动特征的分析以后在这篇论文被建议。主要材料流动事件被描述，包括运动，存储，变，再循环，并且材料的消除。材料流动事件的空间、时间的人物被描述，并且材料流动模型被构造。此处介绍的动态材料流动模型是在 MES 的另外的分系统的基础。另外，它是有在 MES 的最少的规模的分系统。材料流动的动态建模的方法在 SinoMES 模型的发展被使用了。从测量，存储，运动，和材料的留下的平衡的方面管理与坦克和设备有关的全部流动信息帮助石油化学工厂。作为结果，它由错误消除和数据和解匹配生产进程。另外，它便于申请模块的集成进 MES 并且在未来应用保证 SinoMES 的潜在的发展。

The management and control of material flow forms the core of manufacturing execution systems （MES） in the petrochemical industry. The bottleneck in the application of MES is the ability to match the material-flow model with the production processes. A dynamic material-flow model is proposed in this paper after an analysis of the material-flow characteristics of the production process in a petrochemical industry. The main material-flow events are described, including the movement, storage, shifting, recycling, and elimination of the materials. The spatial and temporal characters of the material-flow events are described, and the material-flow model is constructed. The dynamic material-flow model introduced herein is the basis for other subsystems in the MES. In addition, it is the subsystem with the least scale in MES. The dynamic-modeling method of material flow has been applied in the development of the SinoMES model. It helps the petrochemical plant to manage the entire flow information related to tanks and equipments from the aspects of measurement, storage, movement, and the remaining balance of the material. As a result, it matches the production process by error elimination and data reconciliation. In addition, it facilitates the integration of application modules into the MES and guarantees the potential development of SinoMES in future applications.
