深入认识钢铁制造流程的动态运行特征是实现流程动态-有序、协同-连续运行状态管控的基础。基于对钢铁生产流程特征的分析,阐述了“流、流程网络与运行程序”作为钢铁制造流程动态运行3大要素的特征及其数学描述,明确了运行程序是进行物质流、能量流在以流程网络为基础的网络空间中运行优化的调控手段,以及构建铁素物质流及能量流在流程网络上的动态运行优化模型是实现钢铁制造流程高效优质低耗低成本运行的有效途径。对于钢铁制造企业,提出了以生产计划调度优化模型为核心的运行程序优化技术,通过优化模型形成的生产计划调度指令可引导制造流程运行状态的整体优化,实现生产资源的合理优化配置和能源利用效率提升。
Abstract
In-depth understanding of the dynamic operating characteristics of the steel manufacturing process is an important basis for realizing dynamic-orderly, collaborative-continuous operating status. Based on the characteristics analysis of steel production process, the characteristics and mathematical descriptions of "flow, flow network, operating program", which are the three major elements of the dynamic operation of the steel manufacturing process, are elaborated. It is clarified that the operating program is the control measure for the operation optimization of material flow and energy flow in the network space based on the flow network. The construction of the dynamic operation optimization model of the ferrite material flow and energy flow on the flow network is an effective way to realize the high-efficiency, high-quality, low-consumption and low-cost operation of the steel manufacturing process. For steel manufacturing enterprises, an operating program optimization technology centered on the production planning and scheduling optimization model is proposed. The production planning and scheduling instructions formed by the optimization model can guide the overall optimization of the operating state of manufacturing process, and realize the reasonable optimization allocation of production resources and the improvement of energy utilization efficiency.
