    • Abstract:
      En este trabajo se efectúa un desarrollo teórico para realizar control de calidad para variables cualitativas mediante Medias Móviles Ponderadas Exponencialmente (Mempe). El control de calidad para este tipo de variables ha sido ampliamente desarrollado utilizando la metodología clásica de Shewhart. La propuesta considera la definición de estadísticos para realizar este tipo de control, mediante simulación tipo Monte Carlo se obtienen longitudes de ráfaga media, LRM, y los parámetros para su aplicación. Se realiza una comparación del comportamiento que presenta la metodología tradicional con la metodología propuesta, lo que permite deducir que esta propuesta es más eficiente. El método Mempe permite controlar variables cualitativas, con la ventaja de que al realizar el control en un proceso productivo, si este se sale fuera de control, este método entrega una alerta temprana, avisando que la variable en estudio se ha salido de control.

    • Abstract:
      In this work, a theoretical development is carried out to carry out Quality Control for qualitative variables using Exponentially Weighted Moving Averages, MEMPE. Quality control for this type of variables has been widely developed using the classic Shewhart methodology. The proposal considers the definition of statistics to carry out this type of control, through Monte Carlo simulation, average burst lengths, LRM, and the parameters for their application are obtained. A comparison is made of the behavior presented by the traditional methodology with the proposed methodology, which allows us to deduce that this proposal is more efficient. The MEMPE method allows controlling qualitative variables, with the advantage that when controlling a production process, if it goes out of control, this method provides an early warning that the variable under study has gone out of control.
