OEE \u2013 Overall Equipment Effectiveness for High-Performance Industries<\/span><\/h2>

O OEE (Overall Equipment Effectiveness)<\/strong>, or Overall Equipment Effectiveness, is one of the most comprehensive indicators for measuring the real effectiveness of production processes.<\/span>
On analysing Availability<\/strong>, performance<\/strong> e Quality<\/strong>, oh, OEE<\/strong> allows identification of losses, optimisation of resources, and an increase in industrial competitiveness.<\/span><\/p>

This is a critical parameter for organisations seeking reduce operating costs<\/strong>, Improve the quality of the products<\/strong> e ensure deliveries within the agreed deadlines<\/strong>.<\/span>
Measure and monitor OEE<\/strong> consistently translates into more informed decisions and sustained continuous improvement.<\/span><\/p>

OEE stands for Overall Equipment Effectiveness. It is a key performance indicator that measures how well a manufacturing operation is utilized by calculating the percentage of planned production time that is actually productive.\n\nIt is calculated using three factors:\n\n1. **Availability:** This measures the losses due to downtime (planned and unplanned stops).\n * Formula: `Availability = Run Time \/ Planned Production Time`\n * `Run Time = Planned Production Time - Downtime`\n\n2. **Performance:** This measures the losses due to slow cycles or minor stops.\n * Formula: `Performance = (Ideal Cycle Time * Total Count) \/ Run Time`\n * `Total Count = Actual number of pieces produced`\n * `Ideal Cycle Time = Theoretical minimum time to produce one piece`\n\n3. **Quality:** This measures the losses due to defects or rework.\n * Formula: `Quality = Good Count \/ Total Count`\n * `Good Count = Total Count - Defective Parts`\n\nThe OEE is then calculated by multiplying these three factors:\n\n**OEE = Availability \u00d7 Performance \u00d7 Quality**<\/span><\/h3>

The calculation of OEE<\/strong> result of the multiplication of three factors:<\/span><\/p>

  1. Availability<\/strong> \u2013 effective time in which the machine is producing, considering planned and unplanned stoppages.<\/span><\/p><\/li>

  2. Performance<\/strong> \u2013 comparison between actual and ideal production speed.<\/span><\/p><\/li>

  3. Quality<\/strong> Percentage of good units produced relative to the total.<\/span><\/p><\/li><\/ol>

    Practical example:<\/span>
    If a machine has 90% for availability, 95% for performance and 98% for quality, its OEE<\/strong> it will be<\/span><\/p>

    OEE = 0.90 \u00d7 0.95 \u00d7 0.98 = 83,79%<\/strong><\/span><\/p>

    This figure indicates that there is scope to optimise approximately 16% of production capacity.<\/span><\/p>
