Hello all,

I am new to programming in CPLEX and I am trying to solve a problem similar to bin packing problem using constraint programming. 
The items to be added in the bins are linked to each other, e.g. item A needs to be put in a bin before item B can be put in a bin. I believe the scheduling functions such as start_before_start, etc. would be a fit for this constraint, hence I am trying to use interval variables for my tasks and bins but I am unable to do so. 

Any help or ideas on how to use interval variables for bin packing problem are welcome.

Thanks in advance!

P.S @ALEX FLEISCHER Would be helpful if you could provide your inputs on this. Thanks!
