Production management system and associated warning process

Production management system for a production unit for which a schedule of tasks (EQ) to be accomplished is set up and stored in memory in a central management device (36),

• comprising individual electronic devices (12) each associated with an operator (6), control stations (22, 24) comprising inputting and display means and a network (10) linking these individual electronic devices (12) and control stations (22, 24) to a central management device (36),
• in which each individual electronic device (12) includes on the one hand means for inputting tasks performed and problems that may be encountered during the implementation of these tasks by the operator (6) and on the other hand, transmission means for data input to the central management device (36) and
• in which the central management device (36) includes means for comparing between information received from the various individual electronic devices (12) and the schedule of tasks (EQ) to be accomplished stored in memory;
• characterized by the fact that the central management device (36) also includes means to generate a warning when the comparison means have detected a gap between the information received and the schedule of tasks (EQ) to be accomplished that exceed a predetermined and memorized threshold, as well as the transmission means of such a warning towards the individual electronic devices (12, 14) and the control stations (22, 24), and
• by the fact that at least a part of the individual electronic devices (12) and control stations (22, 24) include display means (12, 22) permitting the display of warning signals involving not only the operator (6) associated with the individual electronic device or the control station but also other operators and other control stations.
