A truly uplifting experience. An executable can be found in the folder executable where the necessary executable hall_request_assigner lies.

The code is separated into four major blocks; a cost module, networking module, singleElevator module and a syncModule.

• The singleElevator controls the movements of the elevator, sets its lights, reads buttons and so on. It sends information to the syncModule regarding its state.
• The cost module gets information about all elevators on the network and assigns a workload to the connected elevator. It also transmitts information about Hall Orders to set the correct panel lights.
• The syncModule is a core part which contains a state machine that ensures redundancy of all orders. It shares state information to other elevators through the networking module. A list of orders which can be assigned to all elevators is sent to the cost module for filtering.
• The network sends and recieves orders to other elevator nodes on an udp network. These are depicted below.
