Multi option in CPM model

Post by laysamina » 1 year ago

I am facing a problem with Gams modeling, and will be very appreciated if someone can help me.
I have a problem. I have a flow shop with 7 activities. It should run with CPM(critical path method) and those 7 activities have multiple options to choose.

predecessor - successor
1 2,3,4
2 5
3 5
4 6
5 7
6 7

1- 3 2 10
2 - 70 90
3 - 42 30 52
4 - 15 25 35
5 - 7 14
6 - 10 20 25
7- 14 20

So I should choose the activity option for each activity to create shortest path according to CPM.

Can someone here help me dealing with this? Thanks!
