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。
Oxygen system is an indispensable part of the production of iron and steel enterprises, their working conditions will directly lead to energy waste or affect the normal production of users, thus affecting the economic efficiency of enterprises. In this paper, the characteristics of oxygen generation, storage and use in oxygen enterprises and oxygen system mathematical models are analyzed for the oxygen system. On the basis of this, the optimal proposition of oxygen system scheduling is constructed according to the actual production process. Model and optimize the solution in ILOG CPLEX to simulate this calculation as a scheduling optimization strategy. The effectiveness of the model and the optimization propositions are demonstrated by comparing the scheduling optimization strategy with the simulation based on actual plant scheduling instructions.
