关于优化工具中约束条件的表达

fchsmu

EXTEND中的优化工具中的约束条件如果是含有>=或者<=的数学式子，该如何表示？

个人想法：
5 @- s1 Z# @6 D1 V( a8 D! M# `, {约束条件是在上面的Table里面直接输入最大最小值吧。
Minimum Limit: Table Column 5: The minimum value that this variable can be set to by the Optimizer block. If it is entered without a decimal point, it can only assume integer values. Do not enter limits for variables that are used as results from the model (i.e. Exited from an Exit block).
4 O9 g) @: P  {+ b9 y! B
# M" y/ D2 H8 J" V: |5 z+ kMaximum Limit: Table Column 6: The maximum value that this variable can be set to by the Optimizer block. If it is entered without a decimal point, it can only assume integer values. Do not enter limits for variables that are used as results from the model (i.e. Exited from an Exit block).
; Z" E8 n) n* m" z  y下面的Equation栏里面应该写入目标函数吧。
. o3 f1 z0 M( u6 XMaxProfit （MiniCost）= Var0 + Var1 + Var2;

哦，搞错了，抱歉
2 R" H# N6 w4 [不等式都是在条件里面如
) @  U3 H" `+ S* U( l; eif (DelTankSize >= 6000 && DeliveryTimes < 60）
; s# o& `- ]- mReject = TRUE;  //  你的意思是这个地方是不等式的情况吗？手册里好像没有这样的说明。
