Question

lingo11编的程序,运行说29号错误,我实在不知道为什么错了,请教各位高手：

Answer 1

你在init段写的began的数据量不对 自己改

model:

sets:

workgroup/1,2,3,4,5,6,7/:start,began,cost,last;

second(workgroup,workgroup):c;

endsets

data:

start=2,5,4,0,0,8,9;

cost=5,6,8,4,2,4,2;

last=10,21,15,10,5,15,22;

enddata

init:

!began=4,9,15,0,23,25,29,31;

endinit

min=@sum(workgroup(i):1/7*(cost(i)+began(i)-start(i)));

@for(workgroup(i):began(i)>start(i));

@for(workgroup:@gin(began));

@for(workgroup(i):@bnd(0,began(i),50));

@for(second(i,j)|j#ne#i:c(i,j)=@if(began(j)#gt#began(i),began(j)-began(i)-cost(i),began(i)-began(j)-cost(j)));

@for(second(i,j)|j#eq#i:c(i,j)=1);

end
