From supply chain disruptions, via skilled worker shortages, to rising energy and material costs, manufacturers face a multitude of complex issues that impact their daily business, and these are only a few of them. These are not issues that affect only a few manufacturers, these are global issues that affect the entirety of the manufacturing industry, and overcoming one, two or all three of them becomes a competitive differentiator.

According to a Gartner report, while businesses are eager to reap the advantages of smart manufacturing, they often underestimate the complexities involved, leading to difficulties in making progress. This highlights the critical path ahead for standardizing modern manufacturing and emphasizes the demand for specialized firms to assist manufacturers on this journey.

The Evolution of Smart Factories

From the industrial revolution, to Ford’s assembly line, to today’s smart factories: the manufacturing industry has seen quite the transformation over the last two centuries and depicts a tale of technological evolution and innovation.

The previous three industrial revolutions were each catalyzed by groundbreaking technologies that revolutionized work and production: specifically, steam power, mass production via assembly lines, and computerization. This evolution of the manufacturing industry sets the stage for the smart factories we know today. In the present era, the driving forces behind the fourth revolution, or Industry 4.0, are digital transformation and advanced automation.

Industry 4.0 is a transformative phase in manufacturing, that refers to the use of cutting-edge smart technologies within the manufacturing industry. These technologies include Internet of Things (IoT), Artificial Intelligence (AI), digital twins, cloud computing, Machine Learning (ML) and robotics, among others, where data and connectivity are at the core of all technologies. It creates a more interconnected and efficient industrial environment. The ultimate aim of Industry 4.0 is to establish "smart factories," which are designed to be more resilient, efficient, sustainable, and autonomous.

Today, we speak about smart factories, but what makes these factories “smart” and at what point is a factory “smart”? According to Forbes and TWI-Global, among others, there are four levels to a smart factory.  

Starting with the first level: “Basic Data Availability”. The first level of a smart factory is fundamentally anchored in the availability and connectivity of data and sets the basis of all future stages. In this first stage, the factory needs to become connected to be able to gather relevant insights from its machines and processes down the line. Not only that, but this data also needs to come together in a single place, to merge into a single source of truth. At this stage, data is only available, but not easily accessible or readable.

The shift to easily accessible data takes place in the second stage, the “Proactive Data Analysis” stage. This is when data availability shifts to data analysis, where a significant amount of data is centrally organized and is presented in a more coherent and structured format. Visualization tools and displays aid in data interpretation, enabling proactive analysis. However, some level of effort is still required for in-depth insights.

At the third level, the “Active Data” level, machine learning (ML) and artificial intelligence (AI) are integrated. These technologies significantly enhance the system’s capabilities, facilitating a more autonomous data analysis, generating insights with reduced human intervention. The automation at this stage is notably more advanced than what is found at the second level, offering predictive analytics that can proactively flag potential issues or anomalies. This predictive capability not only elevates operational efficiency but also acts as a safeguard, allowing for preemptive measures to avert potential failures.

The fourth level, or the “Action-Oriented Data Stage”, transcends the reactive and predictive capabilities of the “Active Data” level in that it proactively devises and implements solutions to issues. At this level, data is not just collected and analyzed for potential problems, but solutions are also formulated and executed automatically whenever feasible. This pinnacle of automation showcases a leap in operational efficiency and process optimization, as it allows for real-time adjustments without human oversight.

The evolution from traditional to smart factories is a layered journey, culminating in fully autonomous systems. Next, we'll explore the business case for smart factories, as well as the challenges and solutions that come with them.
