The economic nature of many products manufactured in batch and continuous processes require highly efficient operation due to thin margins. The competing factor in process control is that products must meet certain specifications in order for them to be acceptable. Process Control is the active changing of the process based on the results of process monitoring. Once the process monitoring tools have identified an out-of-control situation, the person responsible for the process must act accordingly in order to bring the process back to control.

Two types of intervention are possible: one is based on engineering judgment and the other is automated. Out-of-control Action Plans detail the action to be taken once an out-of-control situation is detected. A specific flowchart, which leads the process engineer through the corrective procedure may be provided for each unique process.

Advanced Process Control Loops are automated changes to the process that are programmed to correct for the size of the out-of-control measurement. The objective of ADRESS is to study the dynamic performance and controllability of (Bio) sustainable intensified processes.
