The following assignment needs to be solved:
Taskexecuter (operators) travel on a network and are not able to overtake each other.
The operators pick items from a rack and bring them to a sink.
At the end virtual path should be used for the path at the rack. Than if an operator picks from e.g. Bay 3 the other operators should wait at the network node for Bay 2.
Scenario_01
Result: No overtaking so it seems to work, beside that no virtual path is used.
Scenario_02
Virtual Path for the rack.
Result: Orange operator overtakes yellow operator.
Scenario_03
Include some more network nodes which are Virtual Path.
Result: First look it seemed to work, but it is not because the operators go back to the second network node (virtual path).
I tried to make connections from the rack to every network node, but it was the same result as in Scenario_03.
Scenario_04
Include more racks and the connections. Change the logic that it is send to the right rack and always to the Bay 1.
Result: No overtaking in the virtual path section, but the orange operator is overtaking when he gets to the rack, because his target is behind the yellow operator.
Scenario_05
Set the operators to do not travel offsets and block space on networks.
Result: No overtaking, but the operators don’t do travel offset. To model a time for the travel offset could be done by give them a load and/or unload time.
Scenario_06
Include a control for the network node edges to prevent overtaking.
Result: No overtaking so it seems to work.
Attention:
Do not delete or rename the object Logo_FlexsimD, because otherwise the model will not work correctly. Also do not rename, delete or rerank other objects.
