Method and system for handling batch production within ANSI/ISA/95 production scheduling extended with batch production parameter historian

摘要

We add a new entity Production Parameter History to the ISA-95 Production Schedule Model, thereby extending the model. The new entity stores the recent history of the values assumed by a subset of batch parameters most relevant for production control and resource planning, thus without the ERP system being charged with retrieving the historian from a log or from a warehouse in order to schedule the plant production. Putting together the batch information present in the ISA-95 Segment Requirement and the new Production Parameter History, the MES creates and stores a fully Electronic Batch Record close to a real situation found during product manufacturing. The MES system can provide the Electronic Batch Record to the ERP system through the ISA-95 Production Performance model extended thereof, since a production performance report is made up of a set of one or more Production Responses associated with Production Requests.
