Multi-dimensional object oriented approach for automatic generation of control recipes

The chemical acid biochemical industries face intense pressure to improve efficiency, product quality, and human safety, whilst reducing the environmental impact of their operations. Under these circumstances, batch processing is becoming increasingly important. In the batch process operation, the plant information has to be reconfigured dynamically so that it corresponds to the current operation status. This requires the management of plant information reconfiguration as well as the separate handling of process management and unit management, One of the most important tasks of batch process operation management is a management of recipe that is a set of information that defines the production requirements. The current way of manual configuration of production level recipes is tedious and prone to error. In this research, an automatic generation of production level recipes (control recipes) has been proposed. Once a scheduling is carried out, simple transformation rules can generate the control recipe from the master recipe using the plant structure information. It makes the maintenance of control recipes easy. Because the transformation procedure of the master recipe to the control recipe is completely transparent, it is easy to backtrack the rationale of each operation. (C) 2000 Elsevier Science Ltd.
