Hi,

I have a model with two parameters: course and lecturer as illustrated in the attachment.

Each lecturer only teach one course, so I wonder if we can have any other ways which is better than the following:

C=1...5;

L=1..5;

The fact that one lecturer can not teach 5 courses, so it will take zero variables.

Very much appreciate your guidance.

Thanks & regards,

Hi,

why don t you simply write the tuples <Course,Lecture> in your xls ?

Course	Lecture
1	1
2	2
3	3
4	4
5	5
