Source - Inter-Arrival Time - Batch Processing Bug?

In the following model I set Batch Processing as Inter-Arrival time option in the Source object. Both the Batch Size and Cycle time are referenced from a cell of a Global Table as FlexScript data.

When running the model, even with Arrival at time 0 option unchecked the Source is creating one Flowitem. If I check Arrival at time 0 the Source creates two at time 0. Is this a bug? I realized this doesn't happen if the Batch Size is not set as a distribution.

Source_BatchProcessing.fsm
Thanks!

You only posted a video and not a model. If your table cell's data type is String, then Table("GlobalTable1")[1][1] is going to return the string "duniform(75,250)" which will be 0 when cast to a number. If your table cell's data type is FlexScript, then Table("GlobalTable1")[1][1] will evaluate the string and return a random value between 75 and 250.

Without the model, we can't tell how your table data is formatted, but my guess is that it is assigned String data instead of FlexScript data. If not, please post a model demonstrating the issue instead of a video.

Here it is: Source_BatchProcessing.fsm

I assigned FlexScript data for the distribution in the Table.

Thank you!

Your cycle time distribution is returning a negative number: 1650558931472.png

The cycle time needs to return a positive value for the logic of the picklist option to work the way you expect.
