The components of OEE are performance, quality, and availability. OEE stands for Overall Equipment Effectiveness and is a measure of how effectively a manufacturing operation is utilized. Performance refers to the speed at which the equipment is running compared to its maximum speed. Quality measures the number of good units produced compared to the total number of units produced. Availability measures the amount of time that the equipment is available to run compared to the total planned production time.

The correct answer is OEE = AR x PR x QR. OEE stands for Overall Equipment Efficiency, and it is calculated by multiplying the Availability Rate (AR), Performance Rate (PR), and Quality Rate (QR). These three factors represent different aspects of equipment efficiency. The Availability Rate measures the percentage of time that the equipment is available for production, the Performance Rate measures the speed and productivity of the equipment, and the Quality Rate measures the percentage of products that meet the required quality standards. By multiplying these three rates together, we can determine the overall efficiency of the equipment.

The purpose of the OEE (Overall Equipment Efficiency) indicator is to reduce the 6 big losses. OEE is a metric used to measure the effectiveness of a manufacturing process by calculating the percentage of planned production time that is truly productive. The 6 big losses refer to the major factors that contribute to inefficiency in production, including equipment breakdowns, setup and adjustment time, idling and minor stoppages, reduced speed, defects and rework, and startup and yield losses. By focusing on reducing these losses, the OEE indicator helps improve overall efficiency and productivity in the manufacturing process.

OEE stands for Overall Equipment Effectiveness. This metric is used to measure the efficiency and effectiveness of equipment in a manufacturing process. It takes into account three factors: availability, performance, and quality. Availability measures the amount of time the equipment is available for production, performance measures the speed at which the equipment operates, and quality measures the rate of production of good quality products. By calculating OEE, companies can identify areas of improvement and optimize their equipment utilization to maximize productivity.

Each part of OEE (Overall Equipment Effectiveness) cannot be over 1.0 because OEE is calculated by multiplying the availability, performance, and quality factors. Each factor is expressed as a decimal between 0 and 1, representing the percentage of time or efficiency. Therefore, the maximum value for OEE is 1.0, indicating 100% efficiency. If any part of OEE exceeds 1.0, it would imply an efficiency greater than 100%, which is not possible.

Note: AR = Availability Rate, PR = Performance Rate, QR = Quality Rate

The correct answer is QR = Output x 100% / Input. This formula calculates the Quality Ratio (QR) by dividing the output by the input and multiplying it by 100%. It represents the percentage of successful or defect-free output in relation to the input.

The correct answer is PR = Ideal Cycle Time x Output x 100% / Run Time. This formula calculates the Performance Ratio (PR) by multiplying the Ideal Cycle Time, Output, and 100%, and then dividing it by the Run Time. This formula is used to measure the efficiency and productivity of a process or system.

The scheduled downtime is not considered part of OEE because OEE (Overall Equipment Effectiveness) measures the productivity and efficiency of a machine or process during its scheduled production time. Scheduled downtime refers to planned maintenance or other non-production activities that are intentionally scheduled and do not contribute to the overall productivity of the equipment. Therefore, it is not included in the calculation of OEE.

Note: Total downtime = M/C Failure, Material shortage, Change over time
Planned Production Time = All Time - Scheduled Loss
