A computer-implemented method that evaluates a logistics network by calculating impact metrics for potential node failures, identifies substitute suppliers, and creates digital copies to minimize transit time or cost, enabling proactive replacement in case of node failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the logistics network uses existing suppliers and routes, then operational simplicity is maintained, but reliability decreases when node failures occur
Solution Approach 1:
The system performs preliminary actions by proactively identifying critical nodes and pre-planning alternative routes before failures occur. The method calculates impact metrics for potential node failures and pre-identifies substitute suppliers, enabling the logistics network to respond quickly and reliably when actual failures happen, thus improving reliability without requiring complex real-time decision-making.
Solution Approach 2:
The system creates a virtual copy of the logistics network to simulate and evaluate the impact of potential node failures. By modeling the network structure and calculating transit times in this virtual environment, the system can assess reliability risks and identify critical nodes without disrupting actual operations, maintaining operational simplicity while improving reliability assessment capabilities.
2Reliability
If the system evaluates all possible node failures to identify critical nodes, then reliability improves through better preparation, but computational time and complexity increase
Solution Approach 1:
The system applies local quality by focusing evaluation efforts on specific critical nodes and edges rather than uniformly analyzing the entire network. By calculating impact metrics for individual nodes and identifying those with the highest vulnerability, the system achieves reliable failure preparedness while reducing computational time by concentrating resources on the most important areas.
Solution Approach 2:
The system changes parameters by using impact metrics that quantify the effect of node failures on transit time and network reliability. By transforming the complex problem of evaluating all possible failures into a parameter-based assessment, the system can efficiently identify critical nodes and prepare appropriate responses without requiring exhaustive computational analysis of every scenario.
3Adaptability or versatility
If the logistics network maintains multiple substitute suppliers, then adaptability improves for handling failures, but device complexity and management overhead increase
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring network conditions, calculating impact metrics, and updating the identification of critical nodes and substitute suppliers. This feedback loop enables the system to adapt to changing network conditions and maintain appropriate substitute supplier relationships without requiring manual intervention or complex management processes.
Solution Approach 2:
The system performs self-service by automatically identifying critical nodes, calculating impact metrics, and determining appropriate substitute suppliers without requiring manual analysis or intervention. The automated process reduces management overhead while maintaining adaptability, as the system continuously monitors and updates its own knowledge of network vulnerabilities and alternatives.

AI summary
A computer-implemented method includes receiving information of a logistics network representing a factory and associated suppliers of parts, evaluating a first transit time required to receive parts across the logistics network, for each supplier of the associated suppliers creating a digital copy of the logistics network in which a node connecting the supplier to the factory is removed from the digital copy of the logistics network, evaluating a second transit time required to receive parts, for a supplier of the associated suppliers having an impact metric above a threshold identifying a substitute supplier that ships to the factory in the logistics network, and in an event of failure of a given node in the logistics network, replacing in the logistics network a given supplier that uses the given node to ship to the factory and that has an associated impact metric above the threshold with the substitute supplier.
