OPTIMIZATION OF PRODUCTION PLAN OF LARGE-SCALE COAL ENTERPRISES

Being subject to market demand,the coal enterprices have to adjust their production structure,reduce operation cost,improve quality of their products to ensure their existence and development.Based on prediction of production cost,coal sale price and coal output by means of methods such grey system theory,time sequence analysis,breakeven point analysis and regression analysis,a mathematic model of linear programming has been established taking the maximum profit of coal production as target.The model has solved the problems such as production coordination.Besides,sensibility analysis has been done on the model to ensure its reliability and practicability.
