Structured batch logic

Usually the critical part of structuring batch logic is the definition of the phases. There are two ways to approach this ... 

Especially for flexible batch applications, the batch logic must be properly structured in order to oe implemented and maintained in a reasonable manner. An underlying requirement is that the batch process equipment be properly structured. The following structure is appropriate for most batch production facilities. 

The primaiy oojective of the structured approach is to separate cleanly the following two aspects of the batch logic ... 

In structuring the logic for a flexible batch apphcation, the following organization permits produc t technology to be cleanly separated from process technology ... 

Flexible batch applications must be pursued by using a structured approach to batch logic. In such applications, the same processing equipment is used to make a variety of products. In most facilities, little or no proprietary technology is associated with the equipment itself the proprietary technology is how this equipment is used to produce each of the products.
