Optimization for automotive manufacturing
Keep high-mix assembly lines running on schedule while demand, suppliers, and model mix keep changing. Harumi applies operations research and AI to sequencing, capacity, and material decisions across your plants.

How Harumi Delivers Results
Turning automotive planning constraints into optimized decisions
We combine operations research specialists, AI, and a proprietary platform to model the rules of your body, paint, and assembly operations and turn them into plans your team can run.
Expert-Led Assessment
We map your lines, takt times, option content, supplier windows, and inventory policies to find where optimization pays back fastest.
Models built on your plant’s rules
Option spacing rules, paint batching, shift calendars, and just-in-time deliveries become the constraints and objectives of a model built for your operation.
Platform for Continuous Decision-Making
Planners rerun the plan when a supplier is late, a station goes down, or the mix changes, and compare scenarios before committing.
Automotive decisions
From body shop to final assembly: the decisions we optimize
Each of these is a classic operations research problem in automotive manufacturing. Harumi solves them together, so one decision doesn’t break the next.
Define the order of vehicles on the line so labor-intensive options are spaced out, workstations aren’t overloaded, and component consumption stays level.
Smoother workload per station


Group vehicles by color to cut purges and changeovers in the paint shop, then restore the assembly sequence through the painted body buffer.
Less paint and solvent waste
Balance volumes across plants, lines, and shifts, and assign tasks to stations as takt time and model mix change.
Balanced station workloads


Synchronize supplier call-offs, inbound deliveries, and line-side inventory with the build sequence, keeping stock lean without risking a line stop.
Leaner component inventory
Test the impact of a new model launch, a volume shift, a supplier disruption, or an extra shift before changing the plan.
Quantify cost and delivery impact

Expected results
Operational improvements driven by optimization, measured against your current planning baseline.
Fewer line stoppages
Sequences and material plans that anticipate shortages and overloaded stations before they reach the line.
Lower changeover and labor costs
Less paint purge, fewer setups, and less overtime caused by unbalanced workloads.
Better schedule adherence
Build what was planned, in the planned order, and keep just-in-time deliveries on schedule.
Faster replanning
Regenerate a feasible plan when demand, supply, or capacity changes, instead of patching spreadsheets.
Where it applies
Built for the whole automotive value chain
From vehicle assembly plants to the suppliers that feed them, wherever sequencing, capacity, and material decisions are tightly coupled.
Vehicle assembly
Body & stamping
Paint shops
Powertrain & engines
Tier 1 system suppliers
Tier 2 component makers
Plastics & injection molding
Tires & rubber
EV batteries & electronics
Trucks, buses & machinery
Why Harumi
Thousands of option combinations, synchronized suppliers, and little buffer to absorb mistakes. Harumi is designed for planning under those conditions.
Your rules, not generic heuristics
Spacing rules, takt times, tooling limits, and supplier windows are modeled as they exist in your plant.
Optimization planners can trust
We don’t replace planners. Every plan comes with an explanation of its trade-offs, so your team stays in control.
Decisions that stay connected
Sequencing, capacity, and materials are solved together, so a better sequence never creates a shortage downstream.
Connected to your ERP and MES
Harumi connects to the systems you already use for orders, bills of material, and inventory.
Maintained as your plants change
New models, lines, and suppliers are added to the model by our team, so the solution keeps matching reality.
