求助！Lingo程序报错index variables may not share names with other variable

xiangxiu

求大神帮忙看看，运行到目标函数下一行的时候报错 可是看的头大了也没发现有重名的变量名和索引 。

model:

sets:

plant/1..3/PCap,Pprod;

warehouse/1..2/:WCap,Hw, WInitialInv;

retailer/1..4/:RCap,Hr, RInitialInv;

transport/1..3/:TWAR;

endsets

!Formulation;

!Totalcost obj func;

[totalcost]min=@sum(period(t):@sum(plant(i):X(i,t)*Pprod(i)))+@sum(plwaper(i,j,t):Tij*y(i,j,t))

       +@sum(waper(j,t):phi(j,t)*Hw(j))+@sum(reper(k,t):RInv(k,t)*Hr(k))

   

@for(plper(i,t):X(i,t)<PCap(i));

@for(plper(i,t):X(i,t)=@sum(warehouse(j):y(i,j,t)));

@for(waper(j,t):phi(j,t)<WCap(j));

@for(reper(k,t):RInv(k,t)<RCap(k));

求大神给看看

先帮你改写成了一个能用的模型，主要是目标函数删除了一部分有错误东西，你看看是不是有用，如果有用明确写出来是什么，再帮你
