Extended Mediation Analysis for Complex DAGs
Our proposed method extends traditional mediation analysis to handle complex causal graphs, providing a generalized framework for quantifying indirect effects. It addresses the limitations of single-mediator models by accommodating multiple treatments and mediators in high-dimensional DAGs.
The framework leverages do-calculus and counterfactuals to decompose total effects into natural direct and indirect effects, ensuring causal interpretability even in scenarios with intricate interdependencies and non-controllable factors.
Real-World Impact in Logistics and Cloud Operations
The framework's practical utility is demonstrated through case studies in fulfillment center logistics. It quantifies how interventions propagate through complex systems, enabling operational teams to intervene more effectively and identify specific intervention points.
For instance, in cloud infrastructure monitoring, it attributes performance degradation to specific combinations of configuration changes and system metrics, even when multiple causal pathways overlap, supporting real-time decision-making.
Algorithmic Innovations for Enterprise-Scale RCA
To ensure scalability, the framework incorporates algorithmic innovations such as recursive factorization, parallel computation, and structure learning. It addresses challenges like high-dimensional DAGs with both controllable and non-controllable factors.
Robustness is enhanced through techniques for handling unmeasured confounding and model misspecification, including instrumental variable approaches and sensitivity analysis. This ensures reliable causal inference in dynamic, data-rich environments.

Late Deliveries
A simplified view of how driver experience influences late deliveries in fulfillment center logistics, highlighting key causal pathways through mediators.
| Mediator | Driver Experience NIE [late deliveries] |
|---|---|
| Route Affinity | -72 |
| Arrival Time | -965 |
| Loading Time | -730 |
The analysis revealed negative NIEs across all mediators, indicating that increased driver experience reduces late deliveries through multiple pathways. |
