钢铁企业氧气管网的平衡与调度研究

Balance of the oxygen pipe network and scheduling in iron and steel enterprises

氧气系统是钢铁企业生产不可缺少的组成部分,其工作状况会直接导致能源的浪费或影响用户的正常生产,从而影响企业的经济效益。本文针对氧气系统,分析了钢铁企业氧气发生、储存和使用的特点以及氧气系统数学模型,在此基础上,结合实际生产过程构造了氧气系统调度优化命题。在ILOG CPLEX中建模并优化求解,以该计算结果作为调度优化策略进行了仿真。通过将调度优化策略与依据工厂实际调度指令模拟的结果对比,表明了模型及优化命题的有效性。

The oxygen system is an integral part of the iron and steel production. Its working conditions will directly lead to a waste of energy or affect the user＇s normal production, thus affecting the economic efficiency of enterprises. The oxygen system of iron and steel enterprises is discussed in this paper. The characteristics of produce, storage and use of oxygen, also a mathematical model of the oxygen system are analyzed. Based on the mathematical model, a scheduling optimization is proposed considering the actual production process. Then modeling in the ILOG CPLEX and get an optimization solution, the result used as the scheduling optimization strategy for simulation. It shows the effectiveness of the model and the proposed scheduling optimization by comparing the actual command of factory scheduling with the scheduling optimization strategy.
