Processing requires multiple items

[ FlexSim 18.1.1 ]

I am new to FlexSim and trying to model a system with multiple processing arms.

An item arrives into the system approximately every 60 seconds, and is assigned to one of 3 queues (infeed). Each infeed can hold 2 items and items are added to the infeeds in the following sequence 1,1,2,2,3,3,1,1,2,2,3,3 and so on.

Once a queue has 2 items, it passes both of these items to a chamber (process) which takes approx 5 minutes and 30 seconds to complete, upon which the 2 items are then sent onto a combined line for onward processing.

While I can get the infeeds to wait for 2 items, it then only passes 1 onto the chamber for processing.

I could create dual processors for each infeed, but would prefer to do this with a single processor for each feed.

Do I need to use a combiner before the chamber, with a splitter afterwards?

A combiner is a processor. Simply use the combiner as a processor. Try to feed the combiner in the sequence of the items.

I created a model that I believe shows what you are looking for. I wasn't sure if you wanted a separate processing chamber for each feed, or one for all of them. I created a model using just one processor. If you want to use two I can edit it.

The model creates 2 items of each type every 60 seconds and they are processed 2 at a time on the processor before moving on.
