【摘要】 一个大型钢铁企业编制计划时，面临市场需求、生产能力、产品结构、原材料及能源等资源、经济效益之间既困难又错综复杂的平衡和优化问题。本系统采用线性规划技术和大型计算机的计算能力密切结合的方法很好地解决了这个问题。系统设计时注重标准化、规范化，采用两级生成线性规划数学模型，充分利用已有资源将系统划分为三个层次等，对系统的成功开发都是至关重要的，类似系统开发都可借鉴。更多还原

【Abstract】 When making out a production plan of a large iron and sted comples, the difficult and complicated problems of balance.and optimization are md with, Such as the balance balance among market requirement, production capacity,economic benefit, product structure and various resources including raw materials and energies. The linear programing techniques,combined with the computing capability of large scale xomputer,are ed in this article to solve there problems and bring out very good results. Focusing on the standardization and normalization, adopting two-step strategies to generate the mathematical models for linear programing and dividing the system into three lavers are of great importance to the system development. It can Offer valuable methodologies and tools for other similar systems.更多还原
