<p>The present invention provides a system (2) and a method (S1 to S6) for controlling the operations of a manufacturing facility; comprising:
a) a number of production resources (12 to 24) that execute a production process according to a production schedule;
b) a manufacturing execution system (MES) comprising at engineering level a production modeler (PM) to model the production resources (12 to 24) and their production dependencies and/or constraints and a production scheduler (PS) to schedule the production process according to the production orders to be executed thereby using the data model of the production modeler (PM);
c) at least one man machine interface (MMI) and/or graphical user interface (GUI) enabling the user to enter production orders and/or production scheduling data into the manufacturing execution system (MES) and to present all data records being relevant for the user when scheduling the production process in order to get his production order scheduled and executed accordingly;
d) a production scheduler database (DB) that stores all production orders and/or production scheduling data and provides predefined data stored in the database (DB) to the man machine interface (MMI) and/or graphical user interface (GUI) for the user in charge of scheduling; wherein the predefined data is determined sensitive data and/or sensitive class of data out of the data stored in the database (DB); said sensitive data and/or sensitive class of data being required for a real-time scheduling;
e) a data server process (SP) that updates the sensitive data and/or sensitive class of data for the users when a user modified at least part of the sensitive data and/or sensitive class of data; wherein the data server process is enabled to execute an event list queue (ELQ); said event list queue (ELQ) comprising the data modification events launched by the database (DB); said data server process (SP) being further enabled to:
i) periodically check the event list queue (ELQ) for data modification events covering the sensitive data and/or sensitive class of data,
ii) read from the database (DB) only the modified data of the sensitive data and/or the sensitive class of data, and
iii)merge the modified data with the existing data wherein the updated data is accessible by all users.</p> |
