I created the model that allow TS to transfer the item to TE. However, I want to insert more activities for the TS before delivering the item to TE.
As you can see in the picture;
1. I want TS to travel to Queue1 and pick up the item
2. TS unloads the item down to Rack1
3. TS will pick up the item again and travel to the network node in the blue mark
4. TS will push the item to TE
5. TE will travel to sink and release the item, while TS will do the process 1-2 while waiting for TE to come
6. The process flow will run the same as a loop
