6 6 5 0. The last step involves computing the availability of the entire system. 6 5 7 4. The second FOM is Total Ownership Cost (TOC) of the system or equipment under consideration. When equipment availability is 100 per cent, it is always available during planned production times. These calculations have been based on serial and parallel availability calculation formulas. It takes account both Equipment Losses (as measured by OEE) and Schedule Losses (as measured by Utilization).. TEEP is calculated by multiplying four factors: Availability, Performance, Quality, and Utilization. 9,000 ÷28,800 = 31.25% OEE. Your OEE score is presented as a %. Availability (62.5%) x Performance (66.7%) x Quality (75%) = 31.25%. OEE is a closed-loop metric measuring the 3 critical manufacturing components of Availability, Performance and Quality. Below the OEE calculator, we discuss the formulas and details of the OEE calculations. Availability. System availability (also known as equipment availability or asset availability) is a metric that measures the probability that a system is not failed or undergoing a repair action when it needs to be used. 2 7 6 9. Using Control Charts to Display the Results. What is TEEP? Equipment availability is negatively affected by unplanned equipment downtime, material shortages and the time taken for machine changeover. The input and output transducers have fairly high availability, thus fairly high availability can be achieved even without redundant components. Equipment Availability Report Generated for: March 2012 Running Time 471:17:29 Down Time 272:42:31 System Availability 63.35 % Equipment Type: Line 2 Monthly Operating Availability For 0.000 10.00 20.00 30.00 40.00 50.00 60.00 70.00 80.00 90.00 100.0 Weekly Availability Weekly Availability 6 2. At the end there were 9,000 bottles that were saleable, so the Overall Equipment Effectiveness was 31.25%. To calculate a machine’s availability score, divide the operating time by planned production time. Calculating System Availability. hardware availability. Availability is, in essence, the amount of time that an item of equipment or system is able to be operated when desired. TOC for purposes of this handbook is equivalent to cost of ownership. Availability Loss includes Unplanned Stops (such as equipment failures and material shortages), and Planned Stops (such as changeover time). Use our simple OEE Calculator below to quickly calculate OEE, Availability, Performance, and Quality. Availability takes into account Availability Loss, which includes all events that stop planned production for an appreciable length of time (typically several minutes or longer). TEEP (Total Effective Equipment Performance) is a performance metric that provides insights as to the true capacity of your manufacturing operation. To accurately measure system availability, you must monitor all components for outages, then calculate end-to-end availability. Theoretically we could make 480 x 60 = 28,800 bottles. It is most often expressed as a percentage, using the following calculation: Availability = 100 x (Available Time (hours) / Total Time (hours)) 6 0 6 5. The availability, rate of quality product, performance efficiency and the overall equipment effectiveness should each be displayed on their own control chart. Here's a step-by-step guide to these availability calculations. So, for our example, the overall equipment efficiency is given by: Overall Equipment Efficiency = 0.90 x 0.989 x 0.945 = 0.841 or 84.1%. See below 2 methods to calculate your OEE % (Top Line OEE calculation and APQ OEE calculation).
