Resource Flow & System Accounting

← Back to Domain-Specific Families

Abstractions about tracking flows of material, credit, or physical assets through systems, covering material and resource accounting (material flow analysis, non-renewable resource classification), feedback-based system modeling (system dynamics, credit channel), and lifecycle management practices like terotechnology and coprecipitation.

6 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Coprecipitation — In chemistry, coprecipitation (CPT) or co-precipitation is the carrying down by a precipitate of substances normally soluble under the conditions employed.
• Credit channel — Explain how monetary-policy impulses are amplified when financial frictions change borrowers' external-finance premiums or banks' supply of intermediated credit, altering spending beyond the conventional interest-rate channel.
• Material Flow Analysis — A system-boundary accounting method that quantifies stocks and flows of selected materials through processes over a defined period and reconciles them by mass balance to diagnose accumulation, losses, circularity, and data gaps.
• Non-renewable resource — Classify a natural-resource stock as non-renewable when replenishment on the relevant human decision horizon is negligible relative to extraction or consumption, making depletion and stock accounting constitutive.
• System dynamics — A simulation methodology that represents complex systems through accumulations, rates, feedback loops and delays to explain nonlinear behavior over time.
• Terotechnology — Coordinate managerial, financial, engineering, building, and maintenance practices across a physical asset's life cycle to pursue economical whole-life performance through feedback from operation and cost.
