Thanks! I am trying to implement a calendar using the house building example in the cplex manual. To define a step function I need to define breaks. In my case, breaks is defined for each operator. So it should be an array of arrays of tuples of two integers. But the software keeps giving me error: Data array unexpected for "Breaks".
I wrote Breaks = { {<int, int>, <int,int>, ...}, {<int,int>,...},...}
Anything wrong ?

Hello,
You should look at intensity functions when defining the intervals associated with these long tasks.
https://www.ibm.com/docs/en/icos/22.1.1?topic=c-interval-variables-in-cp-optimizer
Essentially, CP Optimizer allows tasks to be suspended at certain times. You should make intensity
0 when the work center is closed. Also, these constraints below might be useful depending on what
you want to do.

Hello
If I need to schedule several production orders and their sizes are larger than 3 days. But my work center capacity is 20 hours per day. Can cplex pause the POs automatically when capacity is reached and continue the PO on a different day ? If yes, what function ? If not, there will be no feasible solution. and will the sizes have to be adjusted manually ?
Thanks
Quan
