Question

我目前正在攻读文学博士学位，因此我一生第一次被迫与GMPL合作。我正面临“文字集中的语法错误”，实际上不知道如何解决此问题。它在目标函数内的第45行中。非常感谢您的帮助！

我知道还有很多其他错误，但是我计划在我的学术顾问的额外帮助下逐一解决它们。请注意，我完全不熟悉编码，并且在我的教育范围内大多绕过编码课程。

我在数据部分中剪切了部分代码，以使文章简短。

编辑：这可能会有所帮助，它是原始模型： enter image description here

#Set of Sets exisitert in GMPL nicht, wie ma mb und mc lösen?
#Kann eig. nicht richtig sein, dass man die Anzahl der Streifen vor Start des Modells festlegen muss

由于目标函数大而导致GMPL语法错误
