Engineering Contradiction Analysis
1Reliability
If numerous simulation runs are carried out to cover a large parameter space, then the reliability of testing complex traffic scenarios is improved, but the resource consumption and time required increase significantly
Solution Approach 1:
The system performs preliminary analysis of error descriptions from simulation runs to identify problematic parameter combinations before executing additional simulations. By pre-processing error data and identifying patterns, the system avoids unnecessary simulation runs that would waste computational resources and time while still ensuring comprehensive testing coverage.
Solution Approach 2:
The system implements a feedback mechanism where error descriptions from simulation runs are continuously analyzed and used to modify subsequent simulation executions. The parameter modifications are based on feedback from previous errors, allowing the system to adaptively avoid repeating the same mistakes and focus on unexplored parameter spaces, thereby improving testing efficiency.
2Reliability
If numerous simulation runs are carried out to cover a large parameter space, then the reliability of testing complex traffic scenarios is improved, but the resource consumption increases significantly
Solution Approach 1:
The system performs preliminary analysis of error descriptions to identify problematic parameter combinations before executing additional simulations. This pre-processing step reduces the number of required simulation runs, thereby decreasing computational resource consumption and energy usage while maintaining testing reliability.
Solution Approach 2:
The system uses feedback from error descriptions to adaptively modify simulation parameters and avoid redundant simulations. This feedback-driven approach ensures that computational resources are focused on exploring untested parameter spaces rather than repeatedly executing simulations with known problematic parameters, reducing overall resource consumption.
3Productivity
If error descriptions are analyzed and parameter modifications are made based on previous errors, then the number of necessary simulation runs is reduced, but the complexity of the simulation system increases
Solution Approach 1:
The system introduces an intermediary error analysis component that processes error descriptions and generates parameter modifications. This intermediary layer acts as a mediator between simulation execution and parameter configuration, automatically analyzing errors and suggesting modifications without requiring complex manual intervention, thereby improving efficiency while managing system complexity through modular design.
Solution Approach 2:
The system implements self-service functionality where the error analysis automatically identifies problematic parameters and generates modification suggestions without external intervention. The system serves itself by autonomously learning from previous errors and adapting simulation parameters, reducing the need for complex external control mechanisms and improving productivity.

AI summary
A computer-implemented method for generating a modification suggestion for at least one simulation run of a simulation comprising a plurality of simulation runs. An error description of a simulation run of a first simulation is received, whereby the simulation run whose error description is received is based on a first parameter set comprising a plurality of parameter values. A not yet completed simulation runs of the first simulation or a second simulation with a parameter set that matches the first parameter set in at least one parameter value is identified. The modification suggestion for the identified simulation runs, taking into account the received error description, is generated. A data processing device to carry out the above method, a computer program product, and a corresponding computer-readable data carrier are also provided.
