帮看一下用lingo程序的这个程序错吗?错在哪里
model:
sets:
myset/@file(f:\myfile.ldt)/:@file(f:\myfile.ldt);
endsets
min=@sum(myset(i):ordered(i)*cost(i));
@for(myset(i):
[con1] ordered(i)>need(i));
[con2] ordered(i)
model:
sets:
myset/@file(f:\myfile.ldt)/:@file(f:\myfile.ldt);
endsets
min=@sum(myset(i):ordered(i)*cost(i));
@for(myset(i):
[con1] ordered(i)>need(i));
[con2] ordered(i)
你把具体的ldt文件都给我
再问： seattle,detroit,chicage,denver~ cost,need,supply,ordered~ 12,28,15,20~ 1600,1800,1200,1000~ 1700,1900,1300,1100 求教育
再答： 括号位置错了 model: sets: myset/@file(f:\myfile.ldt)/:@file(f:\myfile.ldt); endsets min=@sum(myset(i):ordered(i)*cost(i)); @for(myset(i): [con1] ordered(i)>need(i); [con2] ordered(i)
再问： seattle,detroit,chicage,denver~ cost,need,supply,ordered~ 12,28,15,20~ 1600,1800,1200,1000~ 1700,1900,1300,1100 求教育
再答： 括号位置错了 model: sets: myset/@file(f:\myfile.ldt)/:@file(f:\myfile.ldt); endsets min=@sum(myset(i):ordered(i)*cost(i)); @for(myset(i): [con1] ordered(i)>need(i); [con2] ordered(i)
