Create transfer framework

[benn02]

It should be possible to transfer patients and vehicles.

Acceptance criteria

• There is a TransferPatientsInSpecificVehicleRequestEvent
  • It contains one or more patient UUID(s)
  • It contains a vehicle UUID
  • It contains a transfer destination that may be a transfer point or a hospital
• There is a TransferSpecificVehicleRequestEvent
  • It contains a vehicle UUID
  • It contains a transfer destination that may be a transfer point or a hospital
• There is a TransferVehiclesRequestEvent
  • It contains a VehicleResourceDescription
  • It contains a transfer destination that may be a transfer point or hospital
  • It contains an optional key that identifies the request
• There is a TransferPatientsRequestEvent
  • It contains a VehilceType string
  • It contains a transfer destination that may be a transfer point or hospital
• There is a RequestReceivedEvent
  • It contains a VehicleResourceDescription specifying what part of the request can be satisfied
  • It contains a key that identifies the request
• There is a StartTransferEvent
  • It contains a vehicle UUID
  • It contains a transfer destination that may be a transfer point or a hospital
  • It contains an optional key identifying the request that caused this event
• There is a LoadVehicleActivity
  • It receives zero or more patient UUID(s), a vehicle UUID, a delay and a destination
  • Additionally, it receives a time span (how long loading should take)
  • It optionally receives a key identifying the request that caused this activity
  • It sends patient, personnel, material and removed events for the affected elements
  • It loads the patient(s) and all the vehicles personnel/material into the vehicle and then waits for the specified time (so that personnel and material are already blocked during the loading time)
  • After waiting, it puts the vehicle in transfer by sending a StartTransferEvent (including vehicle UUID, destination and key (optional)) and changing the vehicles occupation to a intermediate occupation, that will last for one tick.
• The existing TransferVehicleActivity is deleted
  • The AnswerRequestBehavior and AutomaticDistributionBehavior send TransferVehicleTypesRequestEvent instead
• There is a new TransferVehicleActivity
  • It receives all values that are part of a StartTransferEvent
  • If the destination can't be reached, it...
    • ...sends a missing transfer connection radiogram
    • ...sends a TransferConnectionMissingEvent with the request key if a key was specified
    • ...terminates
  • If the vehicle is not completely loaded (personnel and material, patients do not matter), it terminates
  • It starts the transfer of the specified vehicle to the specified destination
  • It sends a TransferSuccessfulEvent with the request key if a key was specified
• There is a LoadOccupation that does not include any further properties
• There is a WaitForTransferOccupation that does not include any further properties
• There is a TransferBehavior
  • It can be configured with the loading time per patient, loading time for personnel and delay between sending vehicles
  • It handles TransferPatientsRequestEvents, TransferPatientsInSpecificVehicleRequestEvent, and TransferSpecificVehicleRequestEvents
    • If the requested vehicle is not occupied, it creates a corresponding LoadVehicleActivity
    • The delay for the activity is computed as max(num_patients × delay_per_patient, delay_for_personnel_and_material)
    • If the requested vehicle is already occupied, it ignores the event
  • It handles TransferVehiclesRequestEvents
    • It creates LoadVehicleActivities as long as there are enough vehicles that are not occupied
    • It sends a RequestReceivedEvent with the same key specifying the amount of available vehicles
    • It sends a VehiclesSentEvent trough a DelayEventActivity to inform the destination about the number of granted vehicles
  • When creating a LoadVehicleActivity, it sets the vehicles occupation to a LoadOccupation
  • It handles StartTransferEvent and adds them to a list of buffered actions. Vehicles get the WaitForTransferOccupation assigned
  • It handles TickEvents and starts a TransferVehicleActivity for the next action from the buffer if the delay between sending is exceeded
  • It shows a list of currently running load vehicle activities
  • It shows a list of currently waiting/buffered transfers
  • It has a user interface that allows the creation of new TransferPatientsInSpecificVehicleRequestEvents
  • It has a user interface that allows the creation of new TransferSpecificVehicleRequestEvents

Depends on

• Create events for removal of elements from a simulated region #884
• Add current occupation property to vehicles #888
