炼焦配合煤的最佳配比问题

用多种不同变质程度的单种煤按一定的比例组成配合煤进行炼焦,是合理利用有限的煤资源,扩大炼焦原料煤范围,提高焦炭质量并增加经济效益的重要方法。但是,如何确定多种煤的合理配比,目前还处于经验估算阶段。本文介绍了作者与上海焦化厂为解决此问题,利用计算机辅助技术寻求最佳配此的初步研究成果,模型的核心分线性规划与线性联立方程组二部分。用Fortran语言编写的程序采用人一机对话,功能选择的方式以方便使用为原则。用今年二月份实际数据进行模拟运算结果,可全月增加销售收入5万多元。按十一月份的最佳配比,预测经济效益可达11万元,目前该模型正在试运行中。

Optimisation of Coke-making Coal Blending Problem

Blending several kinds of simple coal with different metamorphism in a special ratio is an important method for coke-making. It can effectively utilize the limited coal resources, expand the range of coals as raw materials for coke-making, improve the quality of coke and increase the economic benefit.People used to determine the blending ratio of coal by experience.The author used a computer-aided technique to obtain the optimized ratio. The core of the model is made up of two parts: linear programming and a set of linear equations. The program was witten in Fortran with man-machine interactive mode. The model has been used in calculating the blending ration in Nov. It is estimated that an economic benefit of $ 110,000 might be obtained.
