Core Function: Medical Remaining Requirement Determination
Level 3 calculates the remaining requirement for each medical category (e.g., emergency doctor, ambulance, rescue helicopter). All units already suggested by the Area Responsibility (Level 1) or the Equipment Requirements (Level 2) are offset against these requirements.
The Calculation Logic:
Summation of all requirements from active keywords.
Subtraction of units already committed to the operation.
Subtraction of units already suggested by Levels 1 and 2.
Identification and suggestion of remaining capacities based on distance or the fastest route.
Relevant Configuration Fields (Mapping)
The logic compares specific quantity fields in the keyword with the unit categories.
Reference ( | Localization | Target Unit Category ( |
| Amount (Doctor Ground) | Physician
|
| Amount (HEMS) | AIR AMB
|
| Amount (Intensive Care Helo) | AIR ICU AMB
|
| Amount (Ambulance Regular) | AMB Type II, AMB
|
| Amount (Ambulance Urgent) | AMB Type I, AMB
|
| Amount (Ambulance Doctor) | AMB Physician
|
| Amount (Ambulance ICU) | AMB ICU
|
Special Logic: The Physician Component
In addition to vehicle categories, the system evaluates the UnitDoctorOption property.
Requirement "Amount (Doctor)" (
DispatchAmountDoctor): This value requests a medical doctor's qualification, regardless of the vehicle type.Credit: Units configured in the master data with the Doctor Suggestion Option cover this requirement.
Substitution: If Area Responsibility (Level 1) has already suggested a rescue helicopter (RTH), Level 3 recognizes that a doctor is already present. An additional emergency doctor fly-car (NEF) will not be suggested in this case, provided only one doctor was requested.
Selection Process
Level 3 iterates through available EMS resources and checks for matches with remaining requirements:
Filtering: Exclusion of all unavailable units (see article "Availability").
Categorization: Matching whether a unit serves one of the open categories (RTW, NEF, RTH, etc.).
Sorting: Prioritization by distance/travel time.
Filling: The system selects units until all
DispatchAmountcounters of the keywords are at zero or below.
Interaction with Level 1 and 2
Level 3 is highly integrative. It prevents the dispatch of "escort EMS resources" if the tactical units already cover the medical component.
Fire Protection Example: A keyword requests 1x Fire Station (Level 1) and 1x Ambulance (RTW) for crew safety (Level 3). If the Fire Station from Level 1 already includes a vehicle that meets the criteria of an ambulance, Level 3 recognizes this and does not suggest an additional ambulance.
Summary of Priorities
Qualification over Type: Ensuring the medical care level takes precedence.
Avoidance of Redundancy: EMS resources are only added if the tactical dispatch (Fire/Police) does not contain a sufficient medical component.
Geographic Proximity: Within the medically suitable categories, the shortest travel time always decides.
