Production scheduling, solved mathematically.
makespan converts weekly order volumes into production schedules using mathematical programming, then tracks actual vs. planned output in real time.
168h
Full-week coverage
Real-time
Deviation tracking
Live System View
Your entire production flow, mapped and managed.
makespan models every path in your facility — silos, blending, processing, filling. When a disruption hits, re-run the solver from the current position — completed work is locked in.
Features
Schedule, track, and review — all in one place.
From schedule generation to post-week analysis — everything in a single workflow.
Automated Scheduling
Upload your weekly order volumes. makespan generates a full production schedule across all lines, accounting for changeover times, cleaning constraints, and line capacities.
- MILP solver (HiGHS/PuLP)
- Changeover & CIP constraints
- Split-order handling
- Manual override support
AI-assisted scheduling
Describe a scheduling preference in plain text — "use line 3 less this week" or "run product 12345 on line 2 if possible". The AI translates your request into solver constraints, re-runs the optimization, and shows how the result compares to the base schedule.
- Describe preferences in plain text
- See the impact on makespan and per-line hours before committing
- Compare the adjusted result against the original plan side by side
Your request
“Use line 3 less — it's been overloaded lately”
Result vs. baseline
Live Operations
Log actual production against the schedule in real time. Deviations surface immediately — no end-of-week reconciliation.
Results & Analysis
Compare planned vs. actual output week by week. Measure line utilisation, changeover frequency, and makespan trends.
Disruption Re-planning
When a machine goes down or an order changes, re-plan the remaining week from the current position. Completed work is locked in — the solver only touches what's left.

Impact
What teams measure after deployment
makespan generates a production schedule from your order file and tracks actual output against the plan each week.
Less
Manual scheduling work
Planners review and adjust the generated schedule rather than building one from scratch each week.
Real-time
Deviation visibility
Actual vs. planned output tracked per line, per shift — not at end of week.
100%
Order coverage
The MILP solver only produces schedules that satisfy all order volumes and constraints.
Workflow
How it works
Three steps that work with what you already do.
Upload your order file
Export weekly production volumes from your ERP as an Excel file and upload it to makespan.
Review the schedule
makespan generates a full-week schedule. Review it, adjust individual tasks, split orders, or add manual entries.
Track and measure
Log actual production as shifts complete. Compare against the plan and carry findings into the following week.
Built for
Process manufacturers with repetitive, high-volume production
Food & Beverage
Multi-line filling and packaging with varied product mixes and changeover times.
Dairy & Alternatives
Products requiring CIP between runs and hygiene-interval enforcement across lines.
Pharmaceuticals
Strict batch sequencing and product separation enforced as hard solver constraints.
Consumer Goods
High-SKU operations where changeover costs are a significant share of capacity.
