【摘要】 针对应用线性规划求解炼油和石油化工生产计划优化模型中经常发生的不可行解问题，提出了用罚函数技术建立线性规划诊断模型，再从诊断模型解寻找造成不可行解原因的方法，此方法有效地解决了多年来困扰工厂计划人员使用线性规划中遇到的难题。文中还例举了该方法的应用实例。更多还原

【Abstract】 For infeasible solution in solving refinery and petrochemical planning models using linear programming,a method is introduced to find the source of infeasibility of LP result.The main point of the method is to create a diagnostic model using penalty function technique.This method can efficiently overcome the difficulty in using LP which the planners met with for a long time.Some application examples are illustrated in the paper.更多还原
