MES manufacturing execution system includes electronic batch records, process management, plan management, order management, material management, weighing management, quality management, audit trail and other modules. Through the automatic generation of the process to trace information, the strengthening of the existing process error prevention system, the strengthening of the integration of control and production, pre-prevention, in-process control and post-event analysis can be achieved achieved. Through real-time task flow, precise feeding and operation control for key processes, automatic data collection/calculation/early warning, the process cycle can be shortened, the comprehensive manufacturing cost can be reduced, and product quality can be improved. The various information and cost information of the manufacturing process are fed back to the manager in real time, and the indicators are summarized and compared in multiple dimensions to achieve transparent and efficient management. It can realize the quality monitoring and traceability of the whole process of drug production, and meet the data integrity regulations of regulatory authorities.
