Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The testing of complex safety-critical systems, such as railway infrastructure, is challenging due to their distributed logic and interdependent components, leading to manual and time-consuming iterative processes for ensuring adequate test coverage, especially when system logic changes.
Innovation Solution
A computer-implemented method for generating an integration test model that considers communication means, control logic charts, and system configurations to create a reliable and efficient test environment, incorporating test data models and category partition methods to stimulate and verify system responses, thereby reducing the complexity of testing and improving coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual expert knowledge-based testing is used for safety-critical systems, then test coverage can be achieved, but the testing process becomes time-consuming and iterative
Solution Approach 1:
The patent applies preliminary action by automatically generating integration test models from control logic charts before actual testing begins. The system pre-processes the control logic to create executable test models that automatically generate test cases, eliminating the need for manual expert analysis and iterative testing adjustments.
Solution Approach 2:
The patent replaces the manual mechanical process of expert-based test design with an automated computational system. The control logic charts are automatically transformed into integration test models through algorithmic processing, substituting human expert manual work with automated software that generates comprehensive test cases systematically.
2Adaptability or versatility
If system logic changes in complex technical systems, then adaptability is improved, but manual re-testing becomes increasingly time-consuming
Solution Approach 1:
The patent applies dynamics by creating a flexible automated testing system that can dynamically adapt to system logic changes. The integration test model is generated automatically from updated control logic charts, allowing the testing process to dynamically adjust to any system modifications without requiring manual reconfiguration or re-analysis.
3Device complexity
If distributed control logic is used across multiple technical components, then system modularity is improved, but verifying operational characteristics becomes more difficult
Solution Approach 1:
The patent applies segmentation by processing control logic charts from individual technical components separately and then integrating them into a comprehensive test model. Each component's control logic is analyzed independently and automatically transformed into test cases, maintaining modularity while systematically verifying all operational characteristics across the distributed system.
