标题: 请问下面这个程序怎样改可以使数据容量变化
程序如下： model:sets:!定义集合;
gong/1..50/:n;
qi/1..2/:m,s1,t1;
dong/1..50/:;
links(gong,dong):x;
jia(gong,qi):p,s,c,y;
yong(qi,gong):m1;
endsets
min=cmax;!目标函数;
@for(links

bin(x));!决策变量约束;
@for(yong

bin(m1));!0-1决策变量约束;
@for(gong(i)

sum(dong(k):x(i,k))=1);
@for(dong(k)

sum(gong(i):x(i,k))=1);
@for(qi(j)

sum(gong(i):m1(j,i))=1);

@for(qi(j):c(2,j)>=c(1,j)+@sum(gong(i):x(i,2)*p(i,j)));!第五个约束;
@for(qi(j):c(3,j)>=c(2,j)+@sum(gong(i):x(i,3)*p(i,j)));
@for(qi(j):c(4,j)>=c(3,j)+@sum(gong(i):x(i,4)*p(i,j)));
@for(qi(j):c(5,j)>=c(4,j)+@sum(gong(i):x(i,5)*p(i,j)));
@for(qi(j):c(6,j)>=c(5,j)+@sum(gong(i):x(i,6)*p(i,j)));
@for(qi(j):c(7,j)>=c(6,j)+@sum(gong(i):x(i,7)*p(i,j)));
@for(qi(j):c(8,j)>=c(7,j)+@sum(gong(i):x(i,8)*p(i,j)));
@for(qi(j):c(9,j)>=c(8,j)+@sum(gong(i):x(i,9)*p(i,j)));
@for(qi(j):c(10,j)>=c(9,j)+@sum(gong(i):x(i,10)*p(i,j)));

c(1,1)=@sum(gong(i):x(i,1)*p(i,1));
c(1,2)=c(1,1)+@sum(gong(i):x(i,1)*p(i,2));
c(2,2)=c(2,1)+@sum(gong(i):x(i,2)*p(i,2));
c(3,2)=c(3,1)+@sum(gong(i):x(i,3)*p(i,2));
c(4,2)=c(4,1)+@sum(gong(i):x(i,4)*p(i,2));
c(5,2)=c(5,1)+@sum(gong(i):x(i,5)*p(i,2));
c(6,2)=c(6,1)+@sum(gong(i):x(i,6)*p(i,2));
c(7,2)=c(7,1)+@sum(gong(i):x(i,7)*p(i,2));
c(8,2)=c(8,1)+@sum(gong(i):x(i,8)*p(i,2));
c(9,2)=c(9,1)+@sum(gong(i):x(i,9)*p(i,2));
c(10,2)=c(10,1)+@sum(gong(i):x(i,10)*p(i,2));

y(1,2)=m1(1,1)*(t1(1)-s1(1))+@sum(gong(i):x(i,1)*p(i,1));!第八个约束;

y(2,1)+m1(1,2)*(t1(1)-s1(1))+@sum(gong(i):x(i,2)*p(i,1))=@sum(gong(i):x(i,1)*p(i,2))+y(2,2);!第九个约束;
y(3,1)+m1(1,3)*(t1(1)-s1(1))+@sum(gong(i):x(i,3)*p(i,1))=@sum(gong(i):x(i,2)*p(i,2))+y(3,2);
y(4,1)+m1(1,4)*(t1(1)-s1(1))+@sum(gong(i):x(i,4)*p(i,1))=@sum(gong(i):x(i,3)*p(i,2))+y(4,2);
y(5,1)+m1(1,5)*(t1(1)-s1(1))+@sum(gong(i):x(i,5)*p(i,1))=@sum(gong(i):x(i,4)*p(i,2))+y(5,2);
y(6,1)+m1(1,6)*(t1(1)-s1(1))+@sum(gong(i):x(i,6)*p(i,1))=@sum(gong(i):x(i,5)*p(i,2))+y(6,2);
y(7,1)+m1(1,7)*(t1(1)-s1(1))+@sum(gong(i):x(i,7)*p(i,1))=@sum(gong(i):x(i,6)*p(i,2))+y(7,2);
y(8,1)+m1(1,8)*(t1(1)-s1(1))+@sum(gong(i):x(i,8)*p(i,1))=@sum(gong(i):x(i,7)*p(i,2))+y(8,2);
y(9,1)+m1(1,9)*(t1(1)-s1(1))+@sum(gong(i):x(i,9)*p(i,1))=@sum(gong(i):x(i,8)*p(i,2))+y(9,2);
y(10,1)+m1(1,10)*(t1(1)-s1(1))+@sum(gong(i):x(i,10)*p(i,1))=@sum(gong(i):x(i,9)*p(i,2))+y(10,2);

@for(jia:c>=0);!第10个约束;
@for(jia:cmax>=c);!第12个约束;
t1(1)=9;s1(1)=0;
这是十组数据的，怎么改动可使其变为50组，100组的都可以运行？还望大神赐教

不知道发上去怎么回事，变成了表情符号，

看起来是一个MILP问题，我建议你使用Gurobi，可以说是MILP领域目前的state-of-the-art，申请free academic即可。google一下gurobi，去官网下载，目前最新版是6.5.0，不要用网上所谓的什么破解版，这个不提供建模语言，主要是各种API，建议学习python接口。
