Engineering Contradiction Analysis
1Measurement precision
If deterministic models (Factory Physics) are used to model supply chain metrics, then individual metrics like Cycle Time and Throughput can be modeled, but the model does not integrate all key metrics leading to suboptimization
Solution Approach 1:
The patent merges multiple deterministic models into a single stochastic model that simultaneously captures multiple supply chain metrics (cycle time, throughput, work-in-process, inventory levels) and external factors. This integration resolves the suboptimization problem by ensuring all metrics are modeled together rather than separately, allowing for coordinated optimization across the entire supply chain system.
Solution Approach 2:
The stochastic model serves multiple functions simultaneously: it models internal process metrics, incorporates external factors, provides predictive capabilities, and enables optimization across multiple objectives. This multi-functional approach replaces the need for separate specialized models while achieving comprehensive supply chain analysis and optimization.
2Adaptability or versatility
If heuristic approaches (LEAN) are used for supply chain optimization, then certain situations can be addressed effectively, but the heuristics are inappropriate for other situations and do not provide predictions
Solution Approach 1:
The patent changes the fundamental parameters of the modeling approach from fixed heuristics to stochastic models with probability distributions. This allows the system to adapt to different supply chain situations by adjusting model parameters and scenarios while providing quantitative predictions through simulation. The stochastic framework enables both adaptability to various conditions and precise predictive capabilities.
Solution Approach 2:
The system performs preliminary simulations and scenario analysis before making optimization decisions. By pre-modeling various scenarios and their probabilities, the system can proactively identify optimal strategies rather than reacting to situations as they occur. This preliminary action enables both adaptive decision-making and accurate prediction of outcomes.
3Device complexity
If static supply chain models are used, then the model structure remains simple, but the model becomes stale and no longer reflects current business realities
Solution Approach 1:
The patent transforms the static model into a dynamic stochastic model that can adapt to changing business conditions. The model incorporates scenario analysis, probability distributions, and simulation capabilities that allow it to reflect current and future business realities. This dynamic approach maintains model relevance while managing complexity through structured flexibility rather than rigid simplicity.
