【摘要】 本文从实际出发,首先介绍了钢铁企业氧气合理利用支持系统的设计，并结合某钢铁企业具体设备情况和用户情况，介绍氧气合理利用决策支持系统中供氧系统优化运行模型的创建．及如何利用多库协同机制实现数据分析、模型运算和知识推理的功能集成和决策支持。实践证明，该系统根据生产计划和供氧系统实时运行参数，可对用户的氧、氮、氩需求进行预测，从而合理安排氧气生产、使用和贮存等多个环节，给出安全、有效的专家决策，实现氧气的合理利用。更多还原

【Abstract】 The design of Oxygen rational utilization decision-support system is presented. The optimization model of Oxygen supply system is used as an example to show how to use multi-base coordination mechanism to realize the integration and decision support of data analysis. mathematical model calculation and knowledge inference. According to the production schedule and Oxygen supply system data. the system can forecast the Oxygen, Nitrogen and Argon requirement for coordlnating Oxygen production. utilization. transportation and storage, and thus make the safe and effective expert decision to realize rational utilization of Oxygen.更多还原
