Sound familiar?

Where plants lose money to bad forecasts, and where sktime helps.

A plant commits to many things long before they happen: shifts, purchases, spare parts, and power. These four decisions depend most on a good look ahead.

Production planning

Next quarter's orders decide today's shifts and purchases.

Orders swing more the further they travel up the supply chain, a pattern known as the bullwhip effect. sktime forecasts demand per product and per week, with a likely range, so you plan with more than last year's numbers.

MIT Sloan Management Review

Materials

One missing part, and the line waits.

At the peak of the supply crisis, more than three quarters of German industrial firms reported material shortages. Before 2020 the average was 5.2%. sktime forecasts how much of each material you will need and when, so purchasing orders earlier and sees gaps before they reach the line.

ifo Institute, 2024

Spare parts

A part is used twice a year, and then it is needed tomorrow.

Many spare parts are ordered rarely and irregularly. A literature review reports that in some industrial sectors up to 60% of spare parts show this pattern. sktime includes forecasting methods built for irregular demand, so you stock the right parts without tying up cash in the wrong ones.

Bandeira et al., 2026

Plant energy

Power is a large cost, and its price has moved a lot.

For German industrial customers buying 2,000 to 20,000 MWh a year, the electricity price without taxes and levies rose from 7.3 cents per kWh in early 2021 to 18.1 cents in late 2024. A forecast of your plant's load helps you buy closer to what you use and see peaks coming.

Catch it early

Machines often show it before they fail.

A bearing, a pump, or a motor usually starts to behave a little differently before it stops: in vibration, temperature, or power draw. Your sensors already record this. Nobody can watch every signal around the clock, and a person sees the change only once it is large. sktime watches all signals together and reports when they leave their normal pattern. Published cases report warnings several days ahead for a bearing and two weeks to two months ahead for wind turbine parts.

  1. 01

    Learn what normal looks like

    sktime studies the sensor history from healthy operation. You do not need examples of failures. Failures are rare, so most plants have few records of them.

  2. 02

    Watch every signal, all the time

    Live readings from all sensors of a machine are compared with that normal pattern. sktime reports the point where the behaviour starts to drift.

  3. 03

    Warn while there is time to act

    Maintenance receives an alert with the machine and the moment the change began. The team decides whether to order the part, plan the swap for the next stop, or take a closer look.

A real test: a bearing run until it failed

A bearing on a research test rig at the University of Cincinnati ran for about seven days until it failed. Its vibration was recorded every 10 minutes. The recordings of all four bearings went to sktime's detector, and we compared its warning with a simple alarm limit.

Who it is for

Two roles, one plant to keep running.

Managing directors and plant managers

You carry the cost of every stop and every late delivery.

Better forecasts show what the plant has to deliver and what it needs to do so. Early warnings turn some unplanned stops into planned ones. You see the risk before it reaches the shop floor.

Maintenance, planning, and purchasing leads

You decide which part to stock and when to open the machine.

You get one list of machines that need a closer look and a forecast of the parts and materials the next weeks will use. That lets you order earlier and schedule work in planned stops.

What the numbers say

What is at stake in manufacturing.

Surveys and reports show what unplanned stops cost, what predictive maintenance can save, and how early most manufacturers still are with AI. sktime offers many forecasting and detection methods in one open-source toolkit, so you can use them without building everything from scratch.

$125,000

lost per hour of unplanned downtime at a typical industrial business

ABB surveyed 3,215 plant maintenance decision makers in 2023. Over two thirds of the businesses had an unplanned outage at least once a month, and 21% still repair machines only after they fail. Costs differ a lot by sector: Siemens reports $36,000 per hour in consumer goods and $2.3 million in automotive, in large plants.

8-12%

lower maintenance cost with predictive maintenance than with scheduled servicing alone

The US Department of Energy's maintenance guide cites studies of 8% to 12% savings over a program of preventive maintenance alone, and more for facilities that mostly repair after a failure. Deloitte reports 5% to 15% less downtime from its client projects.

24%

of German manufacturers used any AI technology in 2025 (EU: 17%)

That leaves about three in four manufacturers with 10 or more employees at the start. Eurostat counts any AI use, including text and image recognition, so the share for forecasting is likely lower.

These figures come from surveys and reports by vendors, consultancies, and statistical offices, not from sktime projects. Results depend on your plant, your data, and how you maintain today. We work out what is realistic for your business in a first conversation.

sktime is open source: no license fees per user or site.

Your numbers

What could earlier warnings be worth for your plant?

A back-of-the-envelope estimate. Enter what an hour of unplanned downtime costs you and how many hours you lose per year, and see a rough range in euros. The rest are our cautious assumptions, based on public reports.

Not included: savings from better forecasts of demand, materials, and energy, and the cost of setup and support. After a first conversation we give you a fixed price for a trial project.

How we calculate this

Three steps. The hours and the cost per hour come from you. The percentages are fixed assumptions, based on the sources below.

1. What unplanned downtime costs you

hours of unplanned downtime × cost per hour

You set both values. For scale: ABB found a typical cost close to $125,000 per hour in a 2023 survey of 3,215 plants. Siemens reports $36,000 per hour in consumer goods and $2.3 million in automotive, in large plants. At the start values of 150 hours and €50,000, this is €7.5 million a year.

2. What earlier warnings avoid

cost of downtime × 5 to 15% less

Deloitte reports 5% to 15% less facility downtime, based on its client work. At the Italian rail operator Trenitalia, downtime fell by an estimated 5% to 8%. We use 5% (cautious) to 15% (optimistic) as the range.

3. Annual savings

cost of downtime × the percentage from step 2

The expected value is the midpoint of the cautious and the optimistic case.

Annual savings = step 3.

Simplifications: we apply the percentages to all unplanned downtime, although not every failure gives a warning, and every hour costs the same.

This is an illustration, and we do not promise these results. The reduction rates are based on reports on other companies, not on sktime projects. Downtime costs vary a lot between sectors and plants. In the call we will explore options for your own use case.

Before you ask

Questions manufacturers often ask.

We don't use any AI yet. Is it too early for us?
No. In 2025 only about one in four German manufacturers used any AI technology, so you are in good company. Forecasting and machine monitoring are good first projects because you can measure the result: forecast error, spare parts on the shelf, hours of unplanned downtime. A pilot on one product group or one machine shows the effect before you roll it out across the plant.
We have almost no records of failures. Can this still work?
Yes. The early warning learns from normal operation, so you do not need examples of failures. If you do keep records of past failures, sktime can learn from them as well, for example to tell different failure types apart.
We already have sensors and a monitoring system. Does this replace them?
No. sktime works with the data your systems already collect, for example from your control systems, a data historian, or your ERP. Your existing alarms stay in place. sktime adds forecasts and an early warning on top.
How do we avoid false alarms?
Every plant is different, so we set alert thresholds together with your maintenance team, on your own history. Your technicians review each alert before anyone acts. In the pilot we count alerts against real events, so you see how many were useful before you rely on them.
Is our data good enough?
Usually, yes. For forecasts, weekly or daily figures from the last two to three years are enough to start. For machine monitoring, sensor readings from a period of normal operation are the starting point, and we check together whether your data covers it. In early pilots, data preparation and cleaning may be needed. We aim to make the results reusable and, ideally, to improve data quality and governance across the company.
Does our data stay with us, and will it work with our systems?
sktime is designed to run on your own servers or in your own cloud, so your production data does not have to leave the company. Forecasts and alerts go to your planning or maintenance system as files or through an interface. Because sktime is open source and developed by a broad community, you can check what it does at any time and are not tied to a single vendor. The core framework has a permissive license forever, with no license fees and no subscription requirement.
Are we in control of the software in our own system?
Yes. The core framework is open source with a permissive license forever, guaranteed by the non-profit GC.OS. Custom code built for you does not run on proprietary systems elsewhere, and you are not locked out of it. You choose the maintenance model, and we always discuss it with you in advance: either the code is handed over to your team completely, or you pay for continued maintenance.
Who do we sign with, and what if a developer leaves?
Depending on the type of engagement, your contract partner is the German Center for Open Source AI (a non-profit) or sktime Enterprise Solutions GmbH in Ulm, Germany, which provides services and software around sktime. For support after setup, we offer service level agreements (SLA). The non-profit setup keeps maintenance of the framework layer secure in the long term. An SLA is a legally enforceable guarantee that enough developers are always available to help maintain your infrastructure, even if someone leaves.Meet the team
Do we need to hire new people?
No. But we believe in the sovereignty of our users, and that means helping you build a competent team instead of locking you into endless consulting contracts. Our work usually comes with training for your internal teams, for example on AI, forecasting, or Python, so you can operate the system yourselves quickly. If you prefer, we can also handle most requests with our own staff, forward deployed engineers, or freelancers. Your team then carries a minimal load, and your engineers and planners never have to write code.
What does it cost?
The sktime core framework is free, with no license fees per user or site, now or later, and it is governed by a non-profit. You pay for the setup and support you order. Pilots have a fixed price, always agreed in advance. Larger projects have defined deliverables, and we estimate and cap the price in a scoping phase before they start. Custom software or models that we maintain for you may incur costs through an SLA or licensing. We always discuss the contract and billing model with you in advance.

How we start

Three steps to forecasts and warnings you can trust.

  1. 01

    First conversation and scoping

    We look at your data and at where bad forecasts or unplanned stops cost you the most today. From that, we set the scope and a fixed price for the pilot.

  2. 02

    Pilot on your data

    Over two to six months, we build a first system on your own data, for example a demand forecast or an early warning for one machine type, and compare it with how you work today. You get benchmarks, all the code, and a report, and decide from there how to continue.

  3. 03

    Use in daily operations

    Forecasts and alerts go into your daily planning and maintenance routines. Under a service agreement, sktime Enterprise Solutions maintains the system and stays your contact when questions come up.
