lingo语句求解析
sets:
demand/1..6/:a,b,d;
supply/1..2/:x,y,e;
link(demand,supply):c;
endsets
data:
a=1.25,8.75,0.5,5.75,3,7.25;
b=1.25,0.75,4.75,5,6.5,7.75;
d=3,5,4,7,6,11;
e=20,20;
enddata
init:
x,y=5,1,2,7;
endinit
[obj]min=@sum(link(i,j):c(i,j)*(((x(j)-a(i)))^2+(y(j)-b(i))^2)^(1/2));
@for(demand(i):@sum(supply(j):c(i,j))=d(i));
@for(supply(j):@sum(demand(i):c(i,j))

你最好找个教程看看 @for的基本格式就是
@for(集名(下标): 约束条件); 具体哪个是哪个你自己对应一下我想应该能知道吧 基本格式的问题而已
