A CONCEPT FOR MODELING BATCH PLANT-OPERATION

A model for describing batch plant operations based on three basic com ponents is proposed. The three parts represents different views on the problem. The batch objects follow the batch units moving through the plant. The resource objects document relevant features of each process unit. Finally, the control objects include production plans and recip es. We discuss a rationale for this partitioning and argue that our co ncept gives a complete view of the process for plant operation purpose s. The novel feature of the concept is the integration of essential pe rspectives to the operation of a pharmaceutical batch plant into one s tructured information model. This model takes a broader view than just process control and might be used as an agent to integrate and coordi nate operation tasks to improve plant efficiency.
