Here's a step-by-step guide to these availability calculations. The last step involves computing the availability of the entire system. 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%. 6 0 6 5. hardware availability. The availability, rate of quality product, performance efficiency and the overall equipment effectiveness should each be displayed on their own control chart. 2 7 6 9. Availability (62.5%) x Performance (66.7%) x Quality (75%) = 31.25%. 2. See below 2 methods to calculate your OEE % (Top Line OEE calculation and APQ OEE calculation). Time equals money The second FOM is Total Ownership Cost (TOC) of the system or equipment under consideration. Below the OEE calculator, we discuss the formulas and details of the OEE calculations. These calculations have been based on serial and parallel availability calculation formulas. Use our simple OEE Calculator below to quickly calculate OEE, Availability, Performance, and Quality. Calculating System Availability. When equipment availability is 100 per cent, it is always available during planned production times. 1.3 Availability has various meanings and ways of being computed depending upon its use. What is TEEP? Availability is, in essence, the amount of time that an item of equipment or system is able to be operated when desired. 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. OEE is a closed-loop metric measuring the 3 critical manufacturing components of Availability, Performance and Quality. 5 0 6 4. 6 6 5 0. Using Control Charts to Display the Results. Availability Loss includes Unplanned Stops (such as equipment failures and material shortages), and Planned Stops (such as changeover time). Equipment availability is negatively affected by unplanned equipment downtime, material shortages and the time taken for machine changeover. TOC for purposes of this handbook is equivalent to cost of ownership. To accurately measure system availability, you must monitor all components for outages, then calculate end-to-end availability. 6 5 7 4. Calculating system availability. To calculate a machine’s availability score, divide the operating time by planned production time. 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). 9,000 ÷28,800 = 31.25% OEE. TEEP (Total Effective Equipment Performance) is a performance metric that provides insights as to the true capacity of your manufacturing operation. The input and output transducers have fairly high availability, thus fairly high availability can be achieved even without redundant components. Your OEE score is presented as a %. At the end there were 9,000 bottles that were saleable, so the Overall Equipment Effectiveness was 31.25%. 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. Theoretically we could make 480 x 60 = 28,800 bottles. 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.
