Image:LorryRoutingSystem v6.zip

This model simulates a lorry routing system at the UK border where lorries have to go through several checks. For the first hour the site exit is blocked (perhaps due to an accident). It can be observed how the spaces between sheds (queues) are filling up. Each shed has only a small queue capacity except the entrance sheds where we modelled a big parking space for 200 lorries. After one hour the obstruction is removed and it can be observed how the system slowly recovers.
