In environments of operating efficiency, metrics to measure the Overall Efficiency of Equipment (OEE) and production lines is used. This is a metric developed in environments that integrate Total Productive Maintenance (TPM) availability, and the efficiency and quality obtained in the equipment. This indicator that is strategic, and if used in the right way can be very robust for planning and making decisions, in general is not used properly, because Bonly Key Performance Indicators (KPI) are calculated as reference, without going into further analysis of its behavior.
This document presents a stochastic model proposed for the OEE, which allows you to change the paradigm of its analysis; given the fact that the OEE has a random behavior because it is affected by many uncertain factors occurring within the operation of a machine or production line. From the proposed model, several practical considerations regarding its use and implementation are made. The main reflection is related to how important it is to analyze the variability of OEE, since it is very relevant for the ultimate goal of operational efficiency and decision-making.
