A Multi-Agent AI System for Governing a Semiconductor Mega-Fab

An interactive demonstration of how five specialized AI agents, an orchestrator, and a human review board could jointly steer a hypothetical Arizona chip-manufacturing facility through the competing pressures of water scarcity, grid reliability, community trust, regulatory risk, and federal funding milestones.

Modern semiconductor fabrication facilities — "fabs" — are extraordinary industrial systems. A single mega-fab consumes more water than a small city, draws hundreds of megawatts of electricity continuously, and produces tens of thousands of tons of CO₂-equivalent emissions per month. It also operates inside a dense web of social and regulatory expectations: federal CHIPS Act funding milestones, state environmental permits, Indigenous water rights, and the trust of the communities living next to it. Decisions made in one domain ripple immediately into all the others. Push wafer production higher, and water demand rises; water demand rising stresses a drought-vulnerable aquifer; aquifer stress fuels community opposition; community opposition raises permit risk; permit risk freezes CHIPS funding. No single human team can balance all of these in real time, and no single optimization rule can either — because the constraints are physical, social, and regulatory all at once.

This capstone investigates whether a multi-agent AI architecture — five domain-specialist agents, one cross-domain orchestrator, and a monthly human-approval gate — can govern such a facility more honestly than a single monolithic optimizer. "Honestly" is the operative word: the goal isn't to make all the indicators look green. The goal is to make the trade-offs visible. When water stress and grid stress spike simultaneously, somebody has to decide which constraint is doing the binding, what gets sacrificed, and who signs off on the sacrifice. This dashboard is the working model of that decision-making process.

What you are looking at, below
1
Controllable Inputs (left). Four sliders represent the parameters fab management can actually adjust: how much water gets recycled, how much electricity comes from renewables, how many wafers get produced per month, and how invested the company is in community engagement. Three additional sliders represent uncontrollable pressures — aquifer recharge, grid spare capacity, and grid carbon intensity — that simulate environmental shocks the fab must respond to but cannot fix.
2
Constraint Network (center, top). Six live-computed indices show how the inputs cascade into operational reality: water stress, grid stress, community resistance, permit risk, federal CHIPS disbursement likelihood, and overall production utilization. Each bar shows a black tick-mark at the threshold beyond which that constraint triggers a state change. This is the quantitative spine of the system.
3
Operational State (center, middle). The facility's current state — Stable, Stressed, Non-Compliant, In Recovery, or Terminal — derived from which guard thresholds have been crossed. A real fab's regulatory posture, disclosure obligations, and economic standing all hinge on which state it is in.
4
Domain Agents (center, bottom). Five AI agents — Water, Energy, Production, Community, and Economic — each watching their own slice of the system. Every panel shows what its agent is reading (live data), what it is proposing (an action with a verb and rationale), and the parameter changes it wants. The agent owning the binding constraint is highlighted; its proposal carries the most weight.
5
Orchestrator (right, top). The cross-domain coordinator. It identifies the binding constraint — the one pressure currently doing the most damage — and integrates the five agent proposals into a single coherent set of parameter changes. It applies Liebig's Law of the Minimum: relieve the worst-bound constraint first, even if that means declining expansion proposals from other agents.
6
Operations Review Board (right, bottom). The human approval gate. AI agents in this architecture do not directly actuate the fab. They produce reasoned proposals that a human board reviews on a monthly cadence. Clicking "Convene" simulates one board meeting: deltas are applied, the simulation steps forward one month, and the decision is recorded in an audit trail.
Three scenarios are provided to let you observe the system across its operating range: Stable Baseline (all indicators healthy — the boring case, which is the point), Summer Stress (simultaneous water and grid pressure, the realistic Arizona-July case), and Recovery from Non-Compliant (the system starts broken, and you can watch the agents propose remediation cycle by cycle). Adjusting any slider also produces live recomputation — you do not need to use a preset.
Built on a four-layer Model-Based Systems Engineering stack (Causal Loop Diagram, State Machine, Parametric Diagram, Multi-Agent System). Calibrated against TSMC's Fab 21 in Phoenix, Arizona. Figures are directional estimates suitable for pedagogical demonstration, not operational decision-making.

Audit Trail
Pedagogical note. This is not a fab control system. It is a demonstration that the multi-agent architecture is internally consistent: agents observe their domain, propose actions, the Orchestrator resolves trade-offs by Liebig's Law of the Minimum, and the Review Board approves before any parameter changes. The math is the Glossary's Section 2; the states are the State Machine document; the agent topology is dust_cloud_ai_agent_scheme.md.
