West Friendship, MD · poissonconsulting.com
Named for the Poisson process — the mathematics of uncertainty, arrival rates, and the stochastic behavior of real supply chains.
Supply chain jams, bureaucratic congestion, and compliance failures are not “culture” problems — they are physics problems. We apply the laws of thermodynamics, fluid dynamics, and constraint theory to diagnose structural friction that conventional management frameworks miss.
Our working papers on SSRN — and our peer-reviewed academic publication — emerge from the same problems we solve for clients. Twenty-eight years of global supply chain execution informs every framework. We formalize what practitioners know intuitively but rarely prove.
Poisson Consulting is an exclusively referral-based practice. Engagements are taken selectively, with a small number of active clients at any given time.
Research
Poisson Consulting's research program applies the mathematics of physical systems — thermodynamics, fluid dynamics, game theory, information theory — to problems that practitioners encounter daily but rarely formalize. Each paper addresses a different scale of the same fundamental question: what happens when we stop treating organizations as purely social systems and start treating them as physical ones? Our methodology, which we call Knowledge Arbitrage, strips business problems of their domain-specific language, identifies structural matches in the hard sciences, and translates the physics back into management interventions.

The Cognitive Bridge: How AI Expands the Adjacent Possible for Cross-Domain Synthesis
Corporate AI strategy is overwhelmingly focused on automation and augmentation. Neither captures the most valuable thing AI enables. This paper argues that large language models have changed the binding constraint on cross-domain innovation by compressing the cost of acquiring structural fluency in a distant domain from years to weeks. The result is a new category of human-AI collaboration — cognitive expansion — distinct from both automation and augmentation, where the scarce resource is no longer knowledge but the cognitive disposition to see structural correspondence across fields.

The Trust Tax: From Ceremonial Verification to Physical Anchoring in Deep-Tier Supply Chains
Global supply chain compliance is experiencing a materiality crisis: the administrative layer of trade — the "Map" — has decoupled from physical reality, the "Territory." Drawing on game theory, information economics, and the 2025 UFLPA enforcement record (77% shipment denial rate), this paper defines the Trust Tax as the aggregate deadweight loss of ceremonial verification that fails to alter the underlying incentive for fraud. We propose the Automated Trust Stack — integrating physical anchoring (isotopic triangulation, PUFs, synthetic DNA), performance-locked smart contract escrow, and decentralized integrity staking pools — as a Shared Destiny Architecture that makes supplier stewardship the economically dominant strategy.

The Entropic Firm: Bureaucracy as a Thermodynamic Necessity
Standard theory attributes the Coasean Ceiling to agency costs. We argue it is a structural necessity derived from information entropy. Modeling the firm as Maxwell's Demon, we show that management is isomorphic to information erasure — an irreducible energy cost per bit of ambiguity resolved. We introduce the Thermodynamic Solvency Ratio and analyze Generative AI as a potential topological escape from this limit, subject to a binding fidelity constraint.

Cavitation-Induced Hysteresis in Economic Networks: A Hydrodynamic Phase Transition Model of Operational Solvency
Standard models of supply chain dynamics treat the Bullwhip Effect as harmonic oscillation in elastic media — assuming capacity is continuous and perturbations reversible. This paper argues that linear approximation holds only within laminar flow regimes and fails to account for topological phase transitions under high-amplitude volatility. Using a hydrodynamic isomorphism, we model the firm as a fluid conduit subject to thermodynamic constraints, deriving a critical threshold where local liquidity drops below fixed solvency requirements. Below this threshold, the node undergoes a discrete phase transition from operational to insolvent state, introducing structural hysteresis and rendering the system non-ergodic over the recovery horizon. We introduce the Net Positive Solvency Head (NPSH) metric and validate empirically against 2021 semiconductor supply data.

Capitalizing Environmental Maintenance Obligations: A Measurement Protocol for Industrial Natural Capital Accounting
National accounts do not capitalize mandatory environmental maintenance costs as a stock-equivalent obligation. We propose a protocol that capitalizes observed defensive expenditures into environmental-economic satellite accounts, applying it to U.S. Manufacturing using Census Bureau PACE data (~20,000 establishments). Adjusting for environmental services price growth, we find a capitalized obligation of $971 billion to $1,309 billion at social discount rates. Three high-entropy sectors whose core processes involve irreversible chemical or thermal transformation carry 54% of the total on 27% of sector revenue. The protocol frames this as a reclassification within satellite accounts and provides a measurement tool for firms facing transition risk.

Digital Dark Matter: The Measurement Crisis of Deflationary Wealth
The Solow Paradox is not a failure of technology — it's a failure of the instrument. This paper demonstrates that the System of National Accounts falls into a "Zero-Price Trap" in the digital economy, where technological efficiency drives marginal prices toward zero, causing recorded GDP to contract even as aggregate utility expands. With the rapid scaling of AI, this measurement gap is widening at an unprecedented rate. We construct the Equivalent Service Model and propose a Digital Solvency Ratio to correct the denominator error in sovereign debt analysis.

Bruce Rishel is the founder and principal of Poisson Consulting, LLC. Since 1998, he has directed large-scale supply chain transformations for organizations including Walmart, Lululemon, Boeing, Novelis, and W.R. Grace — from enterprise SAP rollouts and greenfield distribution automation to full PMO buildouts and integrated business planning programs at nine-figure scale. He has led nine-figure programs including North America's largest AutoStore installation (550 robots, 250,000 bins).
His engineering career began at PricewaterhouseCoopers, where he worked on large-scale ERP implementations and supply chain redesign. He was a supply chain leader at Perot Systems (later acquired by Dell), before founding Poisson Consulting in 2016.
Rishel is a published researcher and author. His peer-reviewed work appears in the Journal of Ancient Philosophy (2020), with additional papers under review at practitioner and academic journals. His working papers on SSRN apply the principles of physical systems — thermodynamics, fluid dynamics, game theory — to the organizational and supply chain problems he has spent three decades solving. A frequent speaker at industry conferences including SAP SAPPHIRE, he co-developed the Warehouse, Inventory and Logistics (WIL) certificate for the Association for Supply Chain Management (ASCM) and the National Retail Federation (NRF) Foundation's RISE Up program.
