Efficient manufacturing is crucial for saving companies time, money, and energy. Overall Equipment Effectiveness (OEE) measures efficiency as a percentage, aiming for perfect quality, high speed, and always-running machinery. By tracking OEE over time, manufacturers can identify bottlenecks, improve maintenance, and optimize processes. Availability measures the frequency of machine downtime, Performance assesses real-world manufacturing speed compared to ideal speeds, and Quality evaluates product defect rates. Calculating OEE requires handling large volumes of time series data from sensors on equipment, and companies must manage this data strategically to gain meaningful insights into their efficiency.
