Process optimization
By deploying AI models on the edge, manufacturers can continuously monitor and analyze various aspects of their manufacturing processes such as resource utilization, energy consumption, and production bottlenecks, empowering them to make data-driven decisions and optimize resource allocation in real-time.

Energy optimization
Because of its ability to analyze real-time data from various sources, edge AI algorithms can identify inefficiencies and recommend actions to optimize energy usage, leading to significant cost savings and reduced environmental footprint.

Flexibility and agility
Edge AI enables the rapid reconfiguration and adaptation of production lines to accommodate changing customer demands, new product introductions, or shifts in market conditions. By processing data locally and making real-time decisions, edge AI empowers manufacturers to respond swiftly to dynamic market forces, providing a competitive edge.

Manufacturing Trends and Challenges Shaping the Future

According to Deloitte’s 2024 Manufacturing Industry Outlook report, manufacturers should continue to embrace digital transformation to contribute to a competitive, resilient future, and to help tackle ongoing manufacturing challenges. Some of the key trends identified in the report include:

Navigating the talent shortage
Labor market tightness is expected to continue into 2024. In a survey conducted by the National Association of Manufacturers (NAM), more than 75% of surveyed manufacturing executives feel that attracting and retaining a quality workforce is their primary business challenge.

In the US, the gap is predicted to reach 2.1 million roles by 2030, says Industry Today. In fact, manufacturers cite a deficit of talent and skills as their toughest challenge in scaling AI use cases. The closer use cases get to production, the harder the deficit bites, according to MIT Technology Review’s Taking AI to the Next Level in Manufacturing report.

Supply chain resilience and agility
The COVID pandemic underscored the vulnerabilities of traditional supply chain models and the importance of resilience and agility. Now and in the future, manufacturers will need to focus on diversifying their supply chains, implement real-time visibility, and explore nearshoring and reshoring strategies to mitigate risk and maintain business continuity. 

Smart factories (powered by edge AI)
Smart factories are rapidly becoming the new standard in the manufacturing sector’s digital transformation. This latest innovation leverages advanced technologies such as the Internet of Things (IoT), artificial intelligence (AI), robotics, and big data analytics to create interconnected systems that stream-line production, minimize downtime, and improve product quality. 

Sustainable and circular manufacturing
With growing concerns over climate change, sustainability has become a top priority for manufacturers. We can expect to see greater emphasis on circular manufacturing practices, which involve designing products for longevity, reuse, and recycling. Additionally, the adoption of renewable energy sources and energy-efficient technologies will become more prevalent.
