Problem involves scheduling a series of products of type A, then incurring downtime, then switching over to schedule products of type B.

I have successfully modeled the time needed to make the changeover with a tuple and noOverlap function. I am currently trying to model the resource consumption. Once the resource of A gets used up, it should change over to product B. Then once it switches back to product A, the resource should be replenished. I can use the cumulFunction to model the initial depletion, but how do I get it to reset once a changover has occured?

Thanks

Hello Patrick,

I'm not sure to understand your question.
Did you consider to use stepAtStar/stepAtEnd?
I suggest you to have a look at CP Optimizer User's Manual>Designing scheduling models>Modeling classical finite capacity resources

Feel free to come back and to give us your model if you need more help.

Regards,

Chris.

Hi Chris,

Thanks for the reply. I read the link you provided and would classify my problem as a renewable resource type. I have figured out the problem I was having earlier, but have come across something that should be relatively straight forward...

I'm getting an error on the "and". I'm trying to say that I have a sequence of tasks, with optional maintenance tasks. What syntax do I need to cram multiple interval names into one sequence?

Found it! it's append.
