Rack Varying Dwell Times

In a rack Flexsim has a minimum dwell time function.

An item goes into the rack and stays for a period of time based on the minimum dwell time function.

If a model runs for a year and the time period is in minutes. (525600 minutes in a year) If a bin in the rack has 12 items. I want to release 3 items from the specific bin each quarter.

Release quantity of 3 at 131400 minutes
Release quantity of 3 at 262800 minutes
Release quantity of 3 at 394200 minutes
Release quantity of 3 at 525600 minutes

How do I do this???

There is an option in the pull down menu in the Minimum Dwell Time option of the rack that is "By Global Table Lookup". I assign a different itemtype to each item release "set" (see Source). Then I created a global table "Release Times" that I put the release time (dwell time) in for each item type. Then it's just a matter of filling in the global table name in the Minimum Dwell Time field and you're done. See the attached sample model for this solution.
