How to "schedule" flow items based off of model completion?

source-arrival-schedule.fsmI'm having difficult trying to explain this in words so bear with me. In the model attached, I'm trying to create an arrival "schedule" based off a per-week demand. I'm creating "lots", which are four flowitems from separate sources, each source/flowitem is an ingredient that makes up one "Lot". We have three sizes of Lots, 1 mg, 2 mg, and 3 mg.

My goal is to have my model represent different amounts of lots in a scenario that may frequently changed based off of our demand. An example would be, in a two week period, (3 shifts, 8 hours/shift) I need to make 3 lots of the 1 mg, then one lot of the 2 mg ,then back to three 1 mg lots and finish with 1, 2 mg lot. Then, in the third week, make 3 lots of 1 mg, and 1 lot of 3mg.

I know how to create schedules based on model time, or specific hours in the day etc. Again, sorry for the wordiness and confusing request.

Here's an example to schedule everything, I made some additions to your model. I added a table called "LotTable" where you can enter the amount of each ingredient it takes for each Lot. In process flow I added a DateTime source where you specify when each of these orders come in. The Create Object activities are each linked to a queue and creates the amount of ingredients per lot specified in the "LotTable" table.14182-source-arrival-schedule.fsm

@Joshua S Thanks for the model. It's on track to what i'm looking for. I guess to simplify the question, I want my source arrivals to be based off "cases" rather that model times. It seems that most cases are based off model times or dates the users wants, but I'm looking for the cases to work per processor cases. For example, I want a source to create 4 boxes. Once those four boxes are ran through a processor, I'd like two boxes created, so on so on by values I input. I've tried open and close ports but I can't get the batches to work.

@Kevin Megee You say values you input, where would these values be inputted and read from?
