The overall equipment effectiveness rate as a measure for process improvement

Abstract

Una forma sistemática de controlar el uso de los recursos productivos es el indicador de Efectividad Global de los Equipos (OEE). La ventaja del OEE es que mide todos los parámetros de la producción industrial: disponibilidad, productividad y calidad en un solo indicador. De acuerdo a la tasa que utiliza dicha fábrica para el cálculo de la disponibilidad y la productividad de las líneas (Tasa de Rendimiento Sintético, TRS) se propone, como aportación del trabajo, mejorar la métrica del OEE.

A systematic way to monitor the use of productive resources is the indicator Overall Equipment Effectiveness (OEE). The advantage of OEE is that it measures in a single indicator all parameters of industrial production: availability, performance and quality. The contribution of this study is to identify factors that cause the deviation of these both rates respect the target previously set by corporate management. A logistic regression model has been formulated. As a practical contribution of this paper, a series of recommendations within the program of continuous improvement of the plant is proposed, promoting the effort to involve employees in this "learning process".
