Abstract: A method for testing compatibility between application software and a mobile working machine. The method includes: operating data that are captured during operation of the mobile working machine are aggregated in a cloud, with the aid of the operating data, the mobile working machine is modeled by a digital twin, and the compatibility of the application software is tested in the cloud with the aid of the digital twin.

Abstract: A method for managing accesses of multiple software components to software interfaces. In the method, a temporal allocation of the software components to the software interfaces is calculated statically based on requirements of the software components with respect to the software interfaces. The allocation is optimized continuously in light of an observed runtime behavior of the software components.

Abstract: A method for determining a value of a variable quantity. A processing unit temporally consecutively receives multiple values of the variable quantity including respective associated detection points in time. Based on at least one of the multiple values and the respective associated detection points in time, the processing unit determines pieces of calculation information, which characterize a calculation rule used for determining a value of the variable quantity at a desired point in time. The pieces of calculation information are transferred from the processing unit together with at least one of the detection points in time to another processing unit, so that the calculation rule is determined there based on the received pieces of calculation information and the received detection points in time, and thus a value of the variable quantity may be determined at a desired point in time.

Abstract: A system for the exchange of messages through an application software. The system includes an abstraction layer for abstracting the messages and an interface library connected to the abstraction layer via a message broker.
