Build a software-defined operating system for modern metal mills designed to compress lead times, increase flexibility, and improve margins.
Objective:
Re-architect scrap-to-metal manufacturing around AI-driven planning, real-time execution, and energy-aware optimization — enabling mills to operate faster, more flexibly, and more profitably.
This is not traditional MES or ERP software.
It is infrastructure for building next-generation American mills.
Core vision:
Most mills optimize for tonnage and furnace utilization.
Modern mills should optimize for:
- Lead time
- Margin per run
- Flexibility for short and custom orders
- Energy efficiency
- Setup-time elimination
The platform should enable mills to move from 8–30 week lead times toward compressed, software-optimized production cycles.
Core system architecture:
1. AI-Driven Production Planning Engine
- Demand-aware scheduling that prioritizes speed and margin, not just tonnage
- Dynamic melt and rolling plans based on order mix
- Short-run optimization to treat small batches as profitable opportunities
- Changeover minimization modeling
- Real-time schedule adaptation when disruptions occur
The system must continuously re-plan as conditions change.
2. Scrap Intelligence and Alloy Optimization
- Scrap batch registration with composition metadata
- Predictive alloy blending to maximize yield and reduce waste
- Dynamic recipe adjustment based on scrap availability and cost
- Margin simulation per recipe before furnace charge
Optimize for yield and profitability, not just spec compliance.
3. Energy-Aware Operations Layer
- Energy cost per ton modeling in real time
- Load-shifting recommendations based on power pricing
- Integration hooks for on-site generation and storage
- Simulation of alternative energy sourcing strategies
- Alerts for energy inefficiency events
Energy must become a controllable production variable.
4. Real-Time Execution and Traceability
- Lot-level event timeline from scrap intake to shipment
- Automated deviation detection during melt, cast, roll, or finishing
- Exception alerts for out-of-spec chemistry
- Automated hold gates for QC anomalies
- Full traceability for compliance and customer transparency
Every ton should be digitally traceable end-to-end.
5. Throughput and Setup-Time Compression
- Changeover tracking and bottleneck analysis
- Setup-time reduction insights
- Equipment utilization heatmaps
- Predictive maintenance signals tied to downtime events
- Simulation of process improvements before deployment
Goal: eliminate variability and tribal knowledge dependence.
6. Order-to-Ship Optimization
- Direct mill quoting capability
- Margin-aware order acceptance logic
- Inventory forecasting tied to demand variability
- Short lead-time commitments backed by real-time production modeling
- On-time shipment probability scoring
Mills should become responsive manufacturers, not backlog managers.
7. Workforce Augmentation Layer
- Operator-friendly interface for desktop and tablet
- AI copilot for operations managers
- Guided override workflows with role-based approvals
- Contextual recommendations during production runs
- Institutional knowledge capture to reduce reliance on tribal expertise
Roles:
- plant-admin
- operations-manager
- procurement-lead
- quality-engineer
- logistics-coordinator
8. Industrial Data Architecture
Data model:
- suppliers
- scrap-batches
- furnace-runs
- alloy-recipes
- production-lots
- qc-tests
- customer-orders
- shipments
- equipment
- downtime-events
- energy-metrics
- schedule-models
- audit-logs
System requirements:
- Event-sourced traceability for every lot
- Exception alerts for spec and schedule deviations
- Role-based approvals for recipe overrides and shipment release
- IoT/SCADA-ready integration architecture
- Deterministic replay of production decisions
- High reliability suitable for industrial environments
Dashboards:
- Lead time compression trend
- Yield by recipe
- Scrap utilization rate
- Energy cost per ton
- Margin per production run
- On-time shipment rate
- Defect trends
- Setup-time reduction over time
Positioning summary:
This is not incremental mill software.
It is the operating system for modern, software-defined metal manufacturing.
It enables:
- Faster lead times
- Profitable short runs
- Energy-optimized production
- Reduced setup time
- Improved margins
- Fully traceable, flexible manufacturing
The goal is to transform legacy mills into modern industrial systems capable of rebuilding domestic metal production at lower cost and higher speed.
Create a modern startup design inspired by Y Combinator (YC) companies.
Choose one bright primary color and build a clean, minimal color scheme around it.
The design should feel bold, simple, and product-focused with strong typography, generous whitespace, and clear hierarchy.
