请教下大佬下图的两个约束在lingo中如何编写？
希望有大佬帮忙解答一下！！！感激不尽！！！model:
sets:
a/1/;
b/1..3/;
c/1..7/;
d/1..3/;
links1(b,a):r1,t1,e1;
links2(b,d,c):a2,r2,h2,g2,e2;
endsets
rr=1; !模拟R;
qq=1; !模拟Q;
ss=1; !模拟S;
ee=1; !模拟E;
vv=1; !模拟V;
@sum(c(h):@sum(b(t):@sum(a(j):rr*r1(t,j))))=
@sum(c(h):@sum(b(t):@sum(a(j)|t#le#2:qq*t1(t,j)+ss*r1(t,j)-s*r1(t+1,j)-ee*e1(t,j))));
@sum(c(h):@sum(b(t):@sum(d(j):vv*a2(t,j,h))))=
@sum(b(t):@sum(c(h):(@sum(d(j)|j#eq#1:rr*r2(t,j,h))+@sum(d(j)|j#eq#2:rr*r2(t,j,h))+@sum(d(j)|j#eq#3:rr*r2(t,j,h)))
-h2(t,j,h)-g2(t,j,h)-e2(t,j,h)));
end
你最后一条公式有问题
