Virtual reality (VR) and augmented reality (AR) technologies provide immersive and interactive experiences for workers, significantly improving training, design, and maintenance in smart factories.

Due to its growing popularity in manufacturing, the virtual reality market is set to grow from $31.4 billion to $50.42 billion by 2031.VR simulates realistic environments, enabling trainees to practice challenging tasks in a safe and controlled setting, as well as supporting virtual walkthroughs and design visualization.

On the other hand, augmented reality (AR), often in the form of smart glasses and mobile devices, overlays digital information onto the physical world. This provides real-time guidance and data visualization for tasks like assembly, maintenance, and quality control. In fact, augmented reality has been shown to increase productivity by 32% and decrease the time it takes to complete tasks by an impressive 42%.

Big Data

According to IBM, 53% of manufacturers utilize big data to gain a competitive advantage. Through big data analytics, manufacturers can extract valuable insights about their operations and uncover hidden trends, patterns, and correlations to make strategic decisions. 

For example, Tesla collects vast amounts of data from sensors placed on different machinery and production lines throughout their facilities. By leveraging this data, they are better able to better predict equipment failures, optimize maintenance schedules, and improve product quality.

Four Levels of Smart Factory Evolution

1. Basic Data Availability

The first level of smart factory evolution is basic data availability. At this stage, you can start collecting a wide range of information from sensors, machinery, and other connected devices. This often includes metrics like production rates, machine uptime, and energy consumption, which in later levels allow you to better understand how your operations are performing.

2. Proactive Data Analysis

Level two involves harnessing advanced analytics tools and techniques to anticipate trends, identify patterns, and uncover insights from data gathered in level one. This means you can detect anomalies, such as deviations in product quality, predict equipment failures, and optimize workflows. In doing so, organizations can typically reduce downtime, increase cost savings, and boost safety.  

3. Active Data

At this level, the data is not only analyzed, but you can also analyze data in real-time to make data-driven decisions and adjust operations. This could include anything as minor as adjusting machine parameters to anything as major as adjusting entire production schedules. By using artificial intelligence and machine learning to analyze incoming data, manufacturing facilities can better respond to changing conditions.

4. Action-Oriented Data

The last and most advanced level of smart factory evolution is action-oriented data implementation, where you can use real-time analytics to not only inform decision-making but also trigger automated actions. At this stage, manufacturing systems can autonomously adjust production parameters, schedule maintenance tasks, and optimize resource allocation based on incoming data.

Six Principles of Smart Manufacturing

Let’s explore the six principles that define smart manufacturing and are essential for manufacturers to follow in order to transform their traditional industrial practices. 

1. Proactive

This first principle involves anticipating and addressing issues, such as equipment malfunctions, before they become problems. This is typically done through proactive data analysis, which involves taking preemptive measures, to optimize operations and maintain seamless production flows. 

2. Resilient

Manufacturing systems must be designed to withstand and quickly recover from disruptions, including supply chain issues, equipment failures, or other unforeseen events. By using predictive analytics and real-time monitoring to anticipate and mitigate potential threats, manufacturers can minimize downtime and maintain productivity even in the face of unexpected challenges.

3. Interoperable

Interoperability underscores the necessity for seamless communication and integration between different systems, machines, and software within the manufacturing environment. By ensuring that all components are effectively exchanging data and working together in real-time, smart factories can achieve greater flexibility, efficiency, and scalability within their ecosystems. 

4. Sustainable

This fourth principle involves minimizing waste and energy consumption. This can be done through efficient resource utilization and eco-friendly practices, which may include investing in energy-efficient technologies. By doing so, organizations can achieve not only cost savings, but also long-term environmental responsibility. 

5. Scalable

Scalability emphasizes the ability of manufacturing systems to easily adapt and expand to changes in production demands without significant overhauls. Scalable systems can accommodate growth without serious disruptions or additional investments, ensuring flexibility and agility in operations. 

6. Secure

Lastly, the security principle focuses on the importance of protecting critical assets and proprietary data from cyber threats and unauthorized access. This includes implementing robust cybersecurity measures, such as authentication protocols, encryptions, and access controls, so that smart factories can ensure the integrity and confidentiality of their sensitive information. 

Smart Manufacturing Challenges

1. Transition from Legacy Processes

Transitioning from legacy processes to modern digital systems can be difficult for manufacturers. This transition can require large up front costs in new equipment, technology, and downtime due to installations and employee training.

However, investments in new technology, such as automation, can reduce labor costs associated with repetitive tasks as well as fill any workforce gaps a facility might be experiencing. For instance, at Cyngn, we offer on-demand service, no infrastructure changes, and we work with vehicles you already use, so that organizations can experience a seamless transition from legacy processes.

However, despite potential upfront costs, this technology can help reduce costs by minimizing high hidden costs related to labor, productivity, and safety. In fact, our studies have shown that it is 50% more expensive to delay your investment in automation. By adopting smart manufacturing technologies organizations can instead combat worker shortages, boost output, and reduce downtime. 

3. Changing Labor Demands

According to a study conducted by Descartes, 76% of today’s supply chain operations are being impacted by labor shortages. On top of this, labor costs for manufacturers have increased 20% since 2010. Rising labor costs coupled with unfilled positions are causing manufacturers to turn to advanced solutions, like automation, to help ease the effects of changing labor demands. 

With automation, for instance, companies can increase their production with fewer workers and at the same time assign their employees to more important and valuable tasks. 

In fact, studies have estimated that automation can free up 30-50% of a skilled worker’s time. This not only allows workers to focus on more valuable tasks, but it also allows organizations to get more work done without incurring extra labor costs to address  labor gaps.

4. Cybersecurity

In 2022, the manufacturing sector constituted 24.8% of all cybersecurity attacks within the industrial world. Cybersecurity threats can jeopardize data integrity, operations, and reputation. 

As outlined by the secure principle, smart manufacturing technology can actually help enhance cybersecurity by implementing real-time monitoring, access controls, and proactive vulnerability management. These capabilities mitigate risks by detecting threats early and protecting sensitive data.
