Hey all,
I am currently working on a model in which there are 3 types of flowitems, each labelled with a different value attached. In the system the items are transported in a very simple way from a queue to a sink via 2 AGVs.
Regarding the current loaded item i want to set up a list which includes information about which AGV is loaded with which item based on the item label.
Is there a way to display the name and labels of the item with the related carrier AGV?
kind regards!

You can build a Statistics Collector to collect/update this data. The general structure of the collector in the attached model is actually based on what FlexSim creates in the background when you add a state chart (or other similar "continuous" chart types) to a dashboard.
On reset, the collector creates a row for each AGV in the "AGVs" group. This is done by returning an array of pointer values to those AGVs in the "Row Values" field.
There are two columns defined under the "Columns" tab. The first just shows which AGV the row refers to. This value is written to the table when the row is first created and not updated anymore after that. (Using the "getID" method to generate a unique ID number for the object and write that to the table is mostly the default way FlexSim charts handle object data. It requires to the set the "Display Format" to "Object". Instead you could also just write the name of the AGV as a string value to the table).
The second column is set to update whenever it is accessed (such as when you are viewing the collector's table or any chart that draws data from it). The expression for the value checks whether the AGV ("rowValue") has any loaded items. If it does, it returns the value of the first loaded item's "LoadType" label, 0 otherwise.
As mentioned above, you can either view the table from the "General" tab or connect the collector to a dashboard chart to display the values there.
There are many ways to do this:
Labels on the AGV: you can create table, array or map and manage those on the load/unload triggers.
Lists: You can have a global list partitioned by AGV with the items pushed to the list or have the list in a process flow to which the AGV is attached again with the items pushed to it.
Tables: You can use Table.query() to select the items and attributes that are subnodes of the AGV.
The key question is from where do you want to access the information, and when - and then where you want it stored.
Hey Jason,
in my case, the specific information about each AGV needs to be accessed by a CP in the model, so that when an AGV is passing through this CP, an array with arrival time, name of the AGV and the type of loaded item is displayed. Also this should be stored in a continous table during the whole timespan till the end of the simulation run.
Then you'll want to use the list option - possibly partitioned by AGV - or you can use a field using the expression value.up to find the item's location (the AGV) . Using the list fields you can set the dynamic flag to ensure they're always updated with live information.
