Cross-Industry Applications
Supply Chain & Logistics
Discover demand propagation equations, inventory oscillation laws, and disruption cascade mechanisms from supply chain data.
One of 34 industries across 8 sectors served by CDE — the Causal Dynamics Engine for Science and Engineering.
The Challenge
Why Supply Chain & Logistics teams still struggle to explain what is happening
Supply chain systems exhibit complex, multi-echelon dynamics: demand propagation through distribution networks, inventory oscillations amplified by ordering policies, production lead-time effects creating delayed feedback loops, and disruption cascades across interconnected suppliers. Modern supply chains generate rich operational data (point-of-sale transactions, inventory levels, shipment tracking, production schedules, supplier performance metrics) but extracting governing dynamics from this data remains a challenge.
Economic Order Quantity formulations, safety stock calculations based on normal demand assumptions, and linear programming for logistics optimization impose structural assumptions about demand distributions and cost structures. These models work under stable conditions but fail during disruptions, demand shifts, or structural changes. The bullwhip effect is well-documented but poorly characterized in specific networks. Current analytics identify correlations but cannot distinguish root causes from correlated symptoms when multiple disruption sources interact.
The CDE Approach
How CDE closes the explanation gap in supply chain & logistics
CDE takes supply chain operational data (demand time-series, inventory histories, lead-time measurements, supplier performance records, logistics costs) and discovers governing dynamics of supply chain behavior. Its discovery modes identify demand propagation equations, inventory oscillation laws, and disruption cascade mechanisms, capturing nonlinear feedback loops, lead-time effects, and multi-echelon interactions that simplified models cannot represent.
Causal mode identifies pathways of supply chain disruptions, separating demand shocks from supply constraints from logistics constraints from policy-induced oscillations, producing causal graphs for targeted resilience strategies. Regime classification detects structural transitions (demand pattern shifts, supplier reliability changes, capacity constraints) enabling proactive management. Every discovery is reproducible and auditable for cross-organizational coordination.
Discovery Engine
How CDE applies here
Causal mode maps pathways through multi-echelon supply networks, identifying where disruptions originate and how they propagate, enabling targeted interventions rather than system-wide responses. Symbolic mode discovers closed-form demand propagation equations, inventory dynamics laws, and lead-time relationships for direct implementation in optimization systems. Regime classification enables dynamic policy adjustment across changing market conditions.
Causal Graphs
Discovers directed causal structure from observational data — identifiable causal graphs, regime classifications, and intervention predictions.
Governing Equations
Extracts compact governing laws grounded in the causal structure — interpretable equations your team can read, verify, and compare against known theory.
Intervention Design
Proposes targeted experiments to resolve ambiguous causal edges — maximizing information gain where the causal structure is still uncertain.
Causal Validation
Negative controls, falsification tests, and identifiability analysis applied to every causal claim before promotion to the evidence ledger.
Typed Scientific Claims
What CDE discovers
Every discovery CDE produces is a typed scientific claim — not a black-box prediction, but a governed, reproducible, auditable piece of scientific knowledge with full provenance.
- Demand propagation equations
- Inventory dynamics models
- Lead time governing laws
- Disruption cascade mechanisms
- Logistics optimization dynamics
Governed Discovery
Make the finding reviewable
Every discovery CDE produces carries the review context around it: a Truth Dial setting, an evidence entry with replay context, and control results including bootstrap stability, out-of-distribution testing, and feature-shuffle validation.
For supply chain & logistics, that means teams can compare runs, justify decisions, and decide whether a finding is ready for internal use, external review, or regulated submission.
