Overall Equipment Effectiveness (OEE) provides an overall measure of performance for a process. The formula is Availability x Performance x Quality: Availability is a measure of how much the process is available vs how much time it was supposed to be available (actual uptime)/(scheduled run time). Performance measures how fast the process runs (pieces produced per unit time)/(standard rate for process). Quality measures the quality of the process, it is typically measured as first pass yield: (Good pcs on 1st try – no rework)/(totl pcs input to process).
The app provides a performance overview for manufacturing, provide diagnostic capabilities in order to improve performance over time to understand the current level of performance: What is it getting better or worse? Why is my performance at its current level? What are the drivers behind the performance? By machine, By cell, By time period? What resources do I invest where to have the biggest impact?
