关于价值系数参数规划的目标函数的SAS求法

在关于价值系数规划的计算中，由于最优基随参数的改变ψ变化，所以当价值系数的参数妒改变时，其目标函数应该是ψ的一次函数。在一般的手工计算中，规模较大的线型规划计算起来比较复杂。在此根据目标函数Z（ψ）是一次函数的特征，应用SAS／or模块的LP过程分析出Z（ψ）的表达式。

SAS or LP Procedure in Solving the Price Parameter Linear Program

In the calculation of parameter linear programming, the optimal base and objective functions change when the parameters change, indicating that the objective function is a simple equation. In handwork calculation, due to a large amount of decisive variables or constraints need to be considered, the calculation tend to become more and more complicated. SAS or LP procedure proves to be the shortest and most effective way to get the objective function.
