第二个“抓狂的脸”是：Q

同学们帮帮忙吧，在线等ing

作者: 赵飞鸽 时间: 2012-11-27 10:17
怎么没人回复我啊。。。

作者: sorjor 时间: 2012-11-27 11:02
我运行了下，运行时报错为：63，说明模型不正确。这个的话得看你的题目了。还有我不知道我改的对不对，你最好把那些表情处理下。然后把你的题目说下。不然光看程序很费劲的。

怎么处理表情符号啊。。。

作者: madio 时间: 2012-11-27 11:55
以后发帖子的时候要选择右边的禁用表情！

作者: sorjor 时间: 2012-11-27 14:16
我把你的程序改了改，求不到可行解，但是程序能运行。
你要的话我待会儿发上来：

中间空出来的那一行有错误，你的条件约束可能太多了，lingo找不到可行解。

像这样的模型，已经不能指望有什么好的结果了，很多时候，我们一点都不注意建模过程，只会罗列一大堆好像不用花钱的约束一样，剩下的就交给lingo求解不管了，这是要不得的。
