  • Publication number: 20130173038
    Abstract: The embodiments herein provide a system and method for managing life cycle of a batch in a production control system in real time. The system comprises of an enterprise management system, manufacturing execution system (MES), task execution assistance (TEA) system and a production control system. The TEA system is interfaced between the MES and the production control system for executing the production request. The batch production request generated by the enterprise management system is received by the MES wherein the MES forwards the batch production request to the TEA system. The TEA system obtains information required to execute the batch production request from the production control system. Upon obtaining the information the TEA system instructs an operator to create the batch in the production control system. The production control system confirms the creation of the batch and updates real time status of the batch to the TEA system.
