Abstract
A method for testing a technical system. The method includes: tests are carried out with the aid of a simulation of the system, the tests are evaluated with respect to a fulfillment measure of a quantitative requirement on the system and an error measure of the simulation, on the basis of the fulfillment measure and error measure, a classification of the tests as either reliable or unreliable is carried out, and a test database is improved on the basis of the classification.
Claims9
A method for testing a technical system, comprising the following steps:
- carrying out tests using a simulation of the system;
- evaluating the tests with respect to a fulfillment measure of a quantitative requirement on the system and an error measure of the simulation;
- based on the fulfillment measure and the error measure, carrying out a classification of the tests as either reliable or unreliable;
- and
- improving a test database based on the classification;
- wherein:
- the classification is carried out by a classifier based on a feature vector;
- the fulfillment measure and the error measure form components of the feature vector;
- the classifier maps the feature vector on one of multiple classes;
- the classification takes place within predefined decision limits between the classes;
- in a preparation phase, the simulation is confirmed by an experimental measurement on the system;
- and
- the decision limits are drawn so that the fulfillment measure taken in the simulation and in the measurement minimally deviates.
A non-transitory machine-readable storage medium on which is stored a computer program for testing a technical system, the computer program, when executed by a computer, causing the computer to perform the following steps:
- carrying out tests using a simulation of the system;
- evaluating the tests with respect to a fulfillment measure of a quantitative requirement on the system and an error measure of the simulation;
- based on the fulfillment measure and the error measure, carrying out a classification of the tests as either reliable or unreliable;
- and
- improving a test database based on the classification;
- wherein:
- the classification is carried out by a classifier based on a feature vector;
- the fulfillment measure and the error measure form components of the feature vector;
- the classifier maps the feature vector on one of multiple classes;
- the classification takes place within predefined decision limits between the classes;
- in a preparation phase, the simulation is confirmed by an experimental measurement on the system;
- and
- the decision limits are drawn so that the fulfillment measure taken in the simulation and in the measurement minimally deviates.
