Traditionally, maintenance schedules have been reactive and are either based on estimates of a machine’s lifetime or based on recommendations from the original equipment manufacturer. Integrating AI in predictive maintenance allows your enterprise to leverage data-driven insights on how equipment or assets are performing and when they will break down.

Manufacturers seek to integrate AI into predictive maintenance strategies to enhance the efficiency and quality of their production lines and significantly improve system reliability. With sophisticated AI-based algorithms, models, and expertise, a predictive maintenance system makes manufacturing operations more reliable and efficient. AI-based predictive maintenance helps promptly identify inefficiencies in equipment and machinery functions, triggering alerts for necessary maintenance. This reduces the probability of failure, increases mean-time-to-failure (MTTF), and mean time between failure (MTBF), and eliminates unnecessary maintenance operations, leading to reduced downtime.
