[求助]求达人帮我修改一下LINGO程序中的不妥之处！！！

模型代码如下：

MODEL:
MIN=Z1+Z2+Z3+Z4;
Z1=@IF(M1#GT#(QI+QP),(M1-QI-QP)*CL0*r,(QI+QP-M1)*CS0)+CI*r*QI+CP*QP;
Z2=@IF(T1#GT#D1,CS1*S1,CL1*L1)+CP1*M1+CT1*T1;
Z3=@IF(T2#GT#D2,CS2*S2,CL2*L2)+CP2*M2+CT2*T2;
Z4=@IF(T3#GT#D3,CS3*S3,CL3*L3)+CP3*M3+CT3*T3;

S1=T1-D1;
L1=D1-T1;
L1<=L1max;
S1<=S1max;
L1max=0.05*D1;
S1max=0.1*D1;
D1-L1max<=T1;
T1<=D1+S1max;

S2=T2-D2;
L2=D2-T2;
L2<=L2max;
S2<=S2max;
L2max=0.05*D2;
S2max=0.1*D2;
D2-L2max<=T2;
T2<=D2+S2max;

S3=T3-D3;
L3=D3-T3;
L3<=L3max;
S3<=S3max;
L3max=0.05*D3;
S3max=0.1*D3;
D3-L3max<=T3;
T3<=D3+S3max;

M3=T3/V3;
M2=(T2+M3)/V2;
M1=(T1+M2)/V1;
V1=0.7;
V2=0.7;
V3=0.7;

CI=490;
r=7.0;
CP=3600;
CP1=175;
CP2=180;
CP3=195;
CT1=360;
CT2=375;
CT3=380;
CS0=500;
CS1=540;
CS2=550;
CS3=565;
CL0=700;
CL1=720;
CL2=750;
CL3=785;

D1=19600;
D2=2744;
D3=480.2;

QI<=16300;
QP<=18700;
END

怎么L1/L2/L3和S1/S2/S3条件都不起作用啊？？

望高人指教啊，急！！！！！！！！！

取

T1=D1;

T2=D2;

T3=D3;

三个条件,满足你给的约束,这就导致S1=S2=S3=0,可能你对题目的理解有误,有疑问的话连题目一起发到tactic2008@qq.com,我看看
