| 摘 要： | 由于装置加工成本和加工量之间的函数关系是非线性的，因此炼油和石油化工生产计划优化模型也变成非线性规划模型，不能直接用线性规划求解。本文提出了将非线性成本函数分段线性化，再用δ方法建立线性混合整数规划数学模型，并用此软件进行求解。还介绍了无混合整数规划软件可用时，用线性规划软件进行求解的案例分析法。

| Abstract: | As operating cost is a non-linear function of throughput, the plan optimization model in petroleum refining and petrochemical production becomes a non-linear model and can not be solved directly by linear programming.Sectional linearization of the function with subsequent solution of the problem by using the delta method of mixed integer programming is suggested. When mixed integer programming software is not available,solution by using linear programming software can be considered,as the case study analysis presented. |
