Cleaning In Place batch

The scheduling of a Cleaning in Place (CIP) batch is based on volume, processing time, transition costs, a number of batches, or absolute time.

These are the possible scenarios for CIP modeling:

• The Absolute-time CIP rule can be used to control bacterial pollution. A resource is contaminated from the start of the first process batch after a CIP batch. When the first process batch is finished, bacterial growth continues even without any further processing. You are required to schedule a CIP batch after 48 hours, disregarding the number of batches that have been processed after the first batch that started the contamination.
• A resource can require cleaning after 10000 kg have been processed since the previous CIP batch. You can define a CIP rule for scheduling the CIP batches when the sum of the batches' quantities exceeds 10000 kg.

CIP batches are displayed as non-productive time in the utilization graph.
