A*Star warehouse picker travel node data

We are working on a warehouse model using A*star and needed to get the information of the following:

a) the path each picker has travelled.

b) congestion in any area at any point of time.


Reviewing the post on forum we noted that information may be extracted from "AStarNavigator>stats/extraData" treenode (https://answers.flexsim.com/questions/54528/heat-map-gradient.html). However, the totalTraversal does not suits our need. We have noted data of our interest is in node "AStarNavigator>variables/travelmembers/Operator7" treenode. It has a list of travelpath and allocations. We have a sample model created attempting to get the allocations but it seems that it only records partial of the information. Is the way attempted in the model is not right?


The sample model has flowitems created into racks and assigned operator/forklift to pick it and send to a floorstorage. As A*StarCalculatePath event happens we will attempt to call getAllocations() and travelPath from the AStar.Traveler object. In this sample a token at time 10.86 sec the A*StarCalculatePath event happened, it is noted that allocations recorded does not include the later nodes beyond time 12.27, though the node "AStarNavigator>variables/travelmembers/Operator7" has the information.
