Abstract

This work proposes a new Shewhart‐type control chart of the Weibull percentile (i.e. the reliable life) as a practical example of a product attained following the Data Technology (DT) approach. DT is briefly introduced as a new discipline defined apart from Information Technology (IT). Following this approach, some specific Bayes estimators are selected from literature and then used to build the above new chart. These estimators allow to improve the control making use of any available kind of data (statistical and non‐statistical). The operative steps of DT approach are fully explained. The results are illustrated by means of a real applicative example. Ce travail illustre une nouvelle carte de contrôle de un percentile (la vie fiable) avec la distribution de Weibull, par un exemple pratique de un nouveau produit à la suite de l'approche nommée Technologie de les Données (DT). La DT est présentée comme une nouvelle discipline à part de la Technologie de l'Information (IT). A' la suite de ce approche, le travail démontre la choix et l'utilisation des estimateurs bayesian connues sous le nom “Estimateurs Bayesian Pratiques”, qui sont appliquées pour développer la nouvelle carte. Ces estimateurs donne plus d'efficacité au processus d'évaluation statistique sans abîmer aucunes informations et aidant l'amélioration de l'estimation et le contrôle de la fiabilité. Un exemple concret montre les résultats de l'application pratique de la Technologie de les Données (DT).
