How we work / Line study

Find the bottleneck

We measure your line, build a model of it and test fixes on the computer first. Then we build the one that pays.

  1. 42 s/unitCut59% busy
  2. 44 s/unitWeld62% busy
  3. 71 s/unitPaint100% busy
  4. 45 s/unitPack63% busy
Example line, not client data. Output follows the slowest station. Work piles up in front of it, and the stations after it wait.

Two versions

Both end with a ranked list of fixes and what each one earns.

  • Line you run today

    Line study

    Output is below what the machines should do, and nobody agrees why. We measure the line, then test fixes on a model of it.

  • Line you are about to build

    Expansion study

    There is nothing to measure yet. We start from your current line and the machine makers' data, and size the new one: stations, buffers, robots.

How a study works

  1. 1 day
    1

    Walk the line

    Scope and fixed price. We map stations, buffers and changeovers with your supervisors, and agree what to improve.

    You get: written scope, fixed price

  2. 2–3 weeks
    2

    Measure

    Real cycle times. We read run state from your machines, or log it with clamps and counters, across a full run with changeovers.

    You get: cycle times, stops and reasons

  3. 1–2 weeks
    3

    Model

    Checked against your week. We build a computer model of the line and compare it to your measured output before we trust it.

    You get: a model that matches your numbers

  4. 1 week
    4

    Test the fixes

    On the model first. A buffer, an operator, a camera, a robot, a new layout. We try each and rank them by payback.

    You get: ranked fixes, with payback

When it pays

And when it doesn't. We tell you on the plant walk.

  • New line or expansion

    Size it before you buy it

    How many stations, how much buffer, how many operators. Cheaper to find out on the model than on the floor.

  • Many products, one line

    Changeovers eat the week

    We test run order and batch sizes before you change the schedule.

  • Mobile robots

    How many robots, not how fast

    Fleet size depends on routes, charging and peak demand. We test your layout before you buy vehicles.

  • Layout change

    Move a cell on paper first

    See what a new layout does to flow and wait times before anyone moves a machine.

  • Output stuck

    Stops nobody writes down

    Measurement shows which stoppage costs the most output. It is often not the loudest one.

  • When it doesn't pay

    The answer is already clear

    One machine is plainly the limit, or there is no way to measure. We say so and go straight to the fix.

A typical study

One line, five to ten stationsExample scope, not a client case study
Problem
Output is below the rated speed, and nobody agrees which station sets it.
We do
Measure every station for two to three weeks, build and check the model, then test the fixes your team suggests and ours.
Timeline
4–6 weeks
Typical range
$10k–15k
How you'll know it worked
The model matches your measured output within a tolerance we agree up front. Each fix has output gained and payback in months.
If you go ahead
The study fee is credited toward the fix. If you stop at the report, that is all you pay.

What you get

  • Measured data

    Cycle times, stops and stop reasons, in a spreadsheet you keep.

  • The model, in your name

    Handed over with its assumptions, so your team can rerun it.

  • Ranked fixes

    Each fix tested on the model, with output gained and payback.

  • A written report

    Findings, assumptions and what we would do first. Short enough to read in one sitting.

  • An honest "not worth it"

    If the model says a fix won't pay, the report says so.

  • A fixed-price fix

    If you want us to build it, the study fee comes off the price. Or take the report to anyone.

Questions plants ask

Why not just buy simulation software?

Packages exist. They need clean data and someone who can build and check a model. We supply both, and we then build the fix.

What does it cost?

Most single-line studies are $10k to $15k at a fixed price, agreed after the plant walk. An expansion study is scoped after the walk. If you buy the fix from us, the fee comes off.

We don't have data. Can you still do it?

Yes, that is the first step. We read run state from your PLCs, read-only, or log it with current clamps and counters. If we can't measure a station, we say so rather than guess.

What if the bottleneck is obvious?

Then skip the study. A day on the floor and a few hours of downtime data answer a lot. We will say so on the plant walk.

How accurate is a model?

As accurate as the data behind it. We check it against your measured output and show you where it does not match.

Is this the same as connectivity?

No. Connectivity is a live downtime board that stays on your floor. A study is a one-off answer. The same links can stay on afterwards and become the board.

Will you push us to buy your fix?

No. The report lists fixes anyone can build, including doing nothing. You can take it to another integrator.

Who builds the model?

Andrew Nash, who created Aurrigo's airport simulator, millions of times faster than real time. Frank Walsh handles the machine signals and the fixes that need hardware.

Can funding help?

Maybe. Programs differ on whether a study is an eligible cost, and most won't cover costs from before you apply. Ask the program first. See tariff relief
