Method For Selecting Multiple Program Functions, Method For Selecting One Program Function, Associated Apparatuses And Associated Vehicle, Ship Or Aircraft

A method for selecting a program function for providing a multiple instances of an implemented function, thereby providing a redundantly implemented function, in a vehicle, a ship, or an aircraft, the method comprising:

• Recording dependencies between single performance values for functional units used for performing the program function and total performance values been stipulated for a redundantly implemented function,
• determining current single performance values of the functional units,
• determining a total performance value for the functional units based on the determined single performance values and the recorded dependencies,
• selecting the program function or another program function for providing the redundantly implemented function based on the total performance value or at least one value determined from the total performance value.

An apparatus for selecting at least one program function for providing a redundantly implemented function in a vehicle, a ship, or an aircraft, the apparatus comprising:

• a memory unit storing:
• recorded first dependencies between single performance values for functional units used for performing a first program function and total performance values been stipulated for redundantly implemented functions, and
• recorded second dependencies between single performance values for functional units used for performing a second program function and the stipulated total performance values,
• a first determination unit that configured to:
• determine current first single performance values of the functional units of the first program function, and
• determine current second single performance values of the functional units of the second program function,
• a second determination unit configured to:
• determine a first total performance value based on the determined first single performance values and the recorded first dependencies, and
• determine a second total performance value based on the ascertained second single performance values and the recorded second dependencies,
• a third determination unit configured to determine a cluster performance value based on the first total performance value and from the second total performance value, and
• a selection unit configured to select the first program function and the second program function or other program functions for providing the redundantly implemented functions based on the cluster performance value or at least one value determined from the cluster performance value.

An apparatus for selecting at least one program function for providing a redundantly implemented function in a vehicle, a ship, or an aircraft, the apparatus comprising:

• a memory unit storing:
• recorded dependencies between single performance values for functional units used for performing a program function and total performance values stipulated for a redundantly implemented function,
• a first determination unit that determines current single performance values of the functional units,
• a second determination unit that determines a total performance value based on the determined single performance values and the recorded dependencies, and
• a selection unit that selects the program function or another program function for providing the redundantly implemented function based on the current total performance value or at least one value determined from the current total performance value.
