Depending on the model such restricted conditions as the top and bottom limitations of variables, the price of iron and steel charge and the demand for the total quantity were analyzed. And also the Excel program- ming solution tool was put into use. Then with the help of the Excel VBA the foreground applica- tion interface was developed. The cost of iron charge for the converter was reduced by 4.4 yuan RMB per tone steel after the model was put into use.
