Ambulance.process_patient(patient_ID: int, patient_location_ID: int, hospital_location_ID: int, simulation_times: dict[str, numpy.ndarray], charging_stations_hospitals: dict[str, list[simpy.resources.resource.Resource | float]], to_hospital_bool: ndarray, SIMULATION_PARAMETERS: dict[str, Any], SIMULATION_DATA: dict[str, Any])#

Processes a patient.

The ambulance first drives to the patient, then performs on-site treatment. If the patient needs to be transported to the hospital, the ambulance drives to the hospital and then drops the patient off.

Parameters:

  • patient_ID (int) – The patient ID.

  • patient_location_ID (int) – The arrival location of the patient.

  • hospital_location_ID (int) – The assigned hospital (in case the patient needs to be transported).

  • simulation_times (dict[str, np.ndarray]) – Contains the interarrival times, the on-site aid times and the drop-off times.

  • charging_stations_hospitals (dict[str, list[sp.resources.resource.Resource | float]]) – The charging stations resources at all hospitals together with their charging speeds.

  • to_hospital_bool (np.ndarray) – Specifies for each patient whether transportation to the hospital is required or not.

  • SIMULATION_PARAMETERS (dict[str, Any]) – The simulation parameters. The parameter PRINT is at least necessary. Note that methods that are called within this method may require more parameters. See main.py for parameter explanations.

  • SIMULATION_DATA (dict[str, Any]) – The simulation data. output_patient is at least necessary. See main.py and the input data section on the ELASPY website for explanations. Note that methods that are called within this method may require more data.

Raises:

Exception –

  1. If an ambulance is already helping a patient. 2. If more than one patient was assigned to the ambulance.
