1.前言 本科研工作从1982年末开始,利用鞍钢1981年度各类统计资料并结合现场调研,采集处理了近百万个数据,于1983年6月试编了第一张“1981年度鞍钢109种产品能源投入产出表”,并在当年四季度进行了该表的校核验算工作。利用该表的数据并设置相应变量,建立了鞍钢能源投入产出——线性规划模型,运用计算机求解,得到了在确保利润条件下的1985年鞍钢合理能源结构方案。在该表的基础上进行了鞍钢能源系统的投入产出分析工作,并预测了鞍钢1990年的能源需求。
1. Foreword This research work started from the end of 1982 and used all types of statistical data of Ansteel in 1981 in combination with on-site investigation to collect and process nearly one million data. In June 1983, the first “ Product energy input-output table ”, and in the fourth quarter of the year of the checking and verification work of the table. Using the data of the table and setting the corresponding variables, the input-output-output linear programming model of Ansteel was established. By means of computer simulation, Ansteel rational energy structure plan was obtained under the condition of ensuring profits. Based on the table, the input-output analysis of Angang’s energy system was carried out and the energy demand of Ansteel in 1990 was predicted.
