针对某火电厂配煤方案的要求，通过引入0-1型整数变量，实现了对混煤中单煤数目的限制，并且在分析现有单煤与混煤煤质关系的基础上，设计了基于配煤成本最低且单煤资源受限的0-1混合整数规划模型.为了获得更低的配煤成本，结合企业自身技术改造和设备升级等方法，在允许混煤煤质参数溢出给定边界值的情况下，通过在目标函数中加入相应的罚函数，修正了上述模型.最后经 CPLEX 求解，获得了成本更低的配煤方案：标煤单价下降了3.6%，而混煤煤质参数的变化不超过给定边界值的0.4%.
針對某火電廠配煤方案的要求，通過引入0-1型整數變量，實現瞭對混煤中單煤數目的限製，併且在分析現有單煤與混煤煤質關繫的基礎上，設計瞭基于配煤成本最低且單煤資源受限的0-1混閤整數規劃模型.為瞭穫得更低的配煤成本，結閤企業自身技術改造和設備升級等方法，在允許混煤煤質參數溢齣給定邊界值的情況下，通過在目標函數中加入相應的罰函數，脩正瞭上述模型.最後經 CPLEX 求解，穫得瞭成本更低的配煤方案：標煤單價下降瞭3.6%，而混煤煤質參數的變化不超過給定邊界值的0.4%.

According to the blending scheme and the relation between single coal and blended coal used in the factory,0-1 mixed integer variables were introduced to limit the number of single coals in blend,and a resource-constrained 0-1 mixed integer programming model based on the minimum blending cost as the objective was established.By combining technical transformation and equipment upgrading and permitting the coal's quality indicators in blend overflow the given boundary values,the corresponding penalty functions were added in objective functions,and the model was revised to obtain a lower unit price of the standard coal.The solution solved by CPLEX is reasonable that the unit price of the standard coal declines 3.6%,but the change of the coal's quality indicators in blend is no more than 0.4%.
