运筹学课设：快餐店用功问题求解？（lingo程序怎么写）？

根据开始时间分类就行了

model:

sets:

time/1..11/:d;

temp/1..8/:n1;

full/1..3/:n2;

endsets

data:

d=9 9 9 3 3 3 6 12 12 7 7;

enddata

min=@sum(temp:n1);

@sum(full:n2)=4;

@for(temp:@gin(n1));

@for(full:@gin(n2));

@for(time(i):@sum(temp(j)|jgt(i-4) and jlei:n1(j))+@sum(full(k)|kgt(i-9) andkne(i-4) and klei:n2(k))>=d(i));

end
