Which of the following is a key AI solution in the manufacturing sector?

Proactive machine maintenance is a pivotal AI solution in the manufacturing sector as it leverages predictive analytics to forecast when machinery is likely to fail or require servicing. This approach allows manufacturers to schedule maintenance activities in advance, minimizing downtime and reducing operational costs. By using AI algorithms that analyze historical data from machines, manufacturers can identify patterns that suggest when wear and tear are likely to occur, thus enabling timely interventions before issues lead to equipment failures.

In contrast, the other options—social media marketing, customer service automation, and market analysis—are more relevant to consumer-facing businesses. Social media marketing focuses on enhancing brand presence and engagement online, while customer service automation improves efficiency in client interactions. Market analysis can provide insights into trends and customer needs, but these applications do not directly address the specific operational improvements sought in manufacturing environments. Therefore, proactive machine maintenance stands out as a critical AI application that directly enhances productivity and efficiency within the manufacturing sector.
