Our vision of Industry 4.0 and the 4 stages of maturity

Our vision of Industry 4.0. Discover how Warp 10 can manage data and processes in industrial context.

Our vision of Industry 4.0

Big data, predictive maintenance, machine learning, Artificial Intelligence, how Warp 10 can help Industry 4.0.

Strong of hundreds of meetings with customers and tens of trade shows, we are able to build a fairly clear vision of what data can bring to Industry 4.0 and how our solution fits in. This vision encompasses many different sectors of the industry: agribusiness, manufacturing, heavy industry, cosmetics, etc.

Your needs

Even if industry is diverse, there are several goals which we found as being recurrent:

  • Production supervision: ability to observe and quantify current manufacturing processes. The idea is to have a vision of the existing based on factual metrics. Many companies rely on individual subjective experience to know the state of the industrial tool.
  • Quality supervision: mass production requires reproducibility of the process and thus to control the quality of what is produced. The so-called "good at first time". The idea is to reduce the number of non-compliant products and reduce the variation in quality.
  • Predictive and proactive maintenance: be able to act on the maintenance of the industrial tool before a breakdown that would affect productivity. This maintenance is predictive when we can have an approximation of when an element will wear or break. And it is proactive when we can plan the replacement when the impact on the production is the smallest. In other words, how to change an element of a machine without slowing the rate of production.
  • Process Optimization: Improved productivity and quality to lower operating, maintenance and production costs while improving manufacturing lead times.

Typical profiles

At this stage, we have observed 4 typical profiles corresponding to different stages of evolution or maturity as to the status of the use of data in Industry 4.0. By no means these profiles are meant to be pejorative. We are not in the judgment but in the factual report.

These stages are

  • At first Homo Subjectis, the one who has a subjective view of the existing,
  • Homo Observabilis, the one who has a factual vision of the existing, which has its indicators
  • Homo Causalis, who finds causation between data sources
  • And then Homo Intelligensis, the one who oversees his industrial tool with machine learning software and artificial intelligence.

As with any evolutionary process, the criteria of the previous stages should be fulfilled before considering the next stage. To be clear, you will not be able to go from Subjectis to Intelligensis directly without having passed the necessary steps.

These stages will allow you to locate yourself on this scale and target the stage you want to reach.

Homo Subjectis

Homo Subjectis
Homo Subjectis

This is the first stage of evolution towards Industry 4.0. It is based on empirical knowledge and subjective observations. It is, for example, the maintenance manager who knows his fleet of machines. He knows, from the noise produced or according to manufacturing deviations observed, he will have to replace a ball bearing. It is, for example, the line manager who, depending on the color of the product or its texture, knows if his line is well adjusted or not. He knows what setting to apply if necessary.

What kind of issues?

Homo Subjectis is often confronted with the following issues:

  • How to capture information when production systems (such as machine tools), are not connected or connectable or have no sensors
  • When these systems are closed or depend on proprietary software and formats
  • When data sources (sensors, machine metrics, etc ...) are in formats and from heterogeneous sources.

Faced with these difficulties, the simplest is to rely on empirical knowledge, the gains of experience. But what happens when the expert is on sick leave or is retiring?

Companies need to have a factual and clear vision of the existing, what is called the observability of the industrial tool.

These observational data are so-called time series. That is, sequences of values ​​that are contextualized and timestamped. This is a very specific typology of data highlighted by the IoT in particular, requiring adapted tools.

Depending on the size of the industrial site and the frequency of measurements, these data can quickly represent large volumes. Traditional tools for storing and manipulating data are not suitable. It is necessary to have the right tool to meet this need.

Similarly, the tools for data analysis, when there is a collection of data, are often rudimentary: the sheet of paper with handwritten notes, Excel sheet and in the best case, Python or Matlab. Unfortunately, these tools are not suitable for manipulating and analyzing time series.

Again, you need the right tools.

Without the right tools, Homo Subjectis risks being deaf, dumb and blind about its production tool.

Homo Observabilis

At this stage, you have an objective, factual vision of your production tool. These observations are made by automated measurements.

The first step is to connect the raw data sources to a centralized system. To do this, it is necessary to set gateways, which transfer the data collected by the PLCs, to convert them to a unified "pivot" format corresponding to your business and your company. It can be data from an ERP or files. The idea is not to twist your model to meet any standard but to adapt tools and gateways to your context.

First stage of Industry 4.0: data collection
First stage of data collection

Once these raw data are collected and centralized, you will be able to create dashboards and alerts. This is the first level of analysis.

Collect data

This is not because today you do not know what to do with data that you will not use tomorrow. Collect as much information as you can, even if you do not see the immediate use. You may regret in 5 years not to have 5 years of history on some indicators.

Once this is in place, you can easily initiate a process of continuous improvement. Indeed, as your production tool is instrumented, your decision-making based on observations will be automatically measured in near real-time. You will observe the effects of your settings. You finally make a step into the predictive maintenance.

Plan, Do, Check Act: Continuous improvement

The dashboard and alerts are just the tip of the iceberg and the simplest part to put in place. The most important thing is the collection and centralization of data. Without this vital element, your dashboards will remain empty of data or meaningless. Do not underestimate this part at the risk of having useless indicators.

At this stage, you will not only have a factual and precise supervision of your production but you will be able to optimize your processes. You will have a digital twin on hand.

Homo Causalis

He is the one who tries to find correlations between various data sources.

To do this, it is important to capture exogenous data to your production tool, such as the hygrometry or the ambient temperature of your factory. These factors outside your production lines can affect the quality of your products or the operation of your tools.

In theory, you already capture endogenous data from your industrial tool.

Finally, add contextual data, such as team schedules, teams rotation statuses, stocks, purchases, etc. A night shift team may have lower productivity or affect the health of your production lines according to the fatigue or the expertise of the operators.

Once these data are ingested, you will be able, with the right tool of analysis, to find correlations between them. For example, a degradation of the texture of your product depending on the degree of hygrometry and the expansion of an element of your machine in connection with the outside temperature. It will enrich your dashboards and alerts.

The benefits

Not only will you have more relevant short-term analysis results, but depending on your depth of history, you will be able to perform long-term analyzes and discover seasonality or perform predictive analysis on your indicators.

Your continuous improvement process will be improved and become more focused.

Once this step is achieved, you will be able to fully benefit from predictive and proactive maintenance. You will find the right time to perform a maintenance operation before a failure by impacting the production line as little as possible or even trigger the action automatically following a warning.

According to us, here you are in Industry 4.0.

This is the last step, considering the state of the art. This is to connect this centralized data source to machine learning tools and/or artificial intelligence. Before on-boarding on this type of project, keep in mind that you will need a sufficient depth of history and a data manipulation tool powerful enough to clean, resynchronize, aggregate data upstream and recover and process downstream results.

With this set of tools, you can virtualize part of the business by automatically anticipating parts orders, anticipating customer orders, etc.

You will be able to automatically identify areas for improvement in your processes, possibly in directions that you do not suspect for now.

Machine Learning / IA

Your maintenance may be partially automated by automatically controlling the setting of some PLCs for example, or by automatically triggering the order of spare parts or interventions of the manufacturer.

You will have reached a high degree of maturity in predictive and proactive maintenance. You can now say that you are in Industry 4.0.
