I've ran into the following problem with a combiner: I'm using it to model a load zone where taxis arrive to the parent node, passengers arrive to the member node, and the number of passengers boarding each vehicle is set by a random.discrete distribution (so that for instance 50% of the taxis have 1 passenger, 30% over 2, and 20% have three). This all works great. But now, instead of having my passengers queue at the input node, I was hoping to make them queue at another upstream node, connected to the member input node by a path and every time a taxi arrives, I would like to send to the combiner only the number of passengers that will be batched with the taxi. I tried using Combiner.BatchQuantity but without success so far. From what I've seen by looking at a display showing Combiner.BatchQuantify, it seems it's continuously going through its possibilities, whether a taxi is at the parent input node or not. Then I thought that maybe the number picked to batch passengers with taxis, was selected from that continuously changing value when a taxi entered the parent node, so I tried using the event ParentInput@Combiner1.Exited (as well as ParentInput@Combiner1.Entered) to extract the batchquantify assigned to that taxi but the value did not match the actual batching. So I guess my question is: is there a way to access the value that is picked by the batching process to use it to send the right number of members to the combiner? Thank you very much for your help.

Hi! I want to model the loading of containers at a terminal. On each terminal there is a queue with containers. Each container has different properties, like the size in TEU (is equal to 1 or 2) and their destination. I want to batch a vehicle (parent entity) to a group of containers (member entities). When the capacity of the vehicle is for instance 10 TEUs, you have to batch an amount of containers to that vehicle. The problem is that I cannot express the Batch Quantity in containers, but only in TEUs. Per container the size in TEUs is known and the containers (member entities) must all have the same destination. What should be the expression for the Batch Quantity? It is the most optimal when the vehicle with a capacity of 10 TEUs will be loaded fully. So, when the first number of containers in the list that will be loaded on the vehicle has a common size of 9 TEUs, the last spot can only be occupied by a 1 TEU container. When the first container waiting is 2 TEUs, this one must wait, but the first 1 TEU container waiting in the queue can be taken by the vehicle. How to model this? Does someone has an idea to model this problem? Thanks!
