Dear Alex Fleischer,

I am sorry if this topic is already discussed in this group, I am new to the CPLEX platform.

I would like to use a set of sets for the following purpose, 

I have a time horizon, T= 1..40; in hours,

I need to split them into five shifts, ( S = 1..5; )
each containing 8 hours. 
so that, 
s[1] should be 1..8;
s[2] should be 9..16;
s[3] should be 17..24;
and so on till s[5] be 33..40;

Could you please suggest me a method to proceed with this?

Thanks and regards,

Bharath
