Object-oriented Bayesian networks for complex quality management problems


  • Flaminia Musella


  • Paola Vicard



Quality management and customer satisfaction evaluation can be difficult tasks to perform when processes involve multiple production lines or provide multichannel services. As a consequence, the top management needs to analyse the problem from different perspectives, to evaluate possible improvement strategies at several levels and to take appropriate decisions. To this aim, we propose to use object-oriented Bayesian networks by which different quality aspects and evaluations can be integrated in a unique framework allowing to analyse improvement strategies in real time. We show, by an application to an internal-customer satisfaction survey, how to combine the perceived quality of different production areas and how to evaluate the impact on the global quality of improvement actions developed in one or more areas.
