Production planning and optimization
SMEs manufacturing chemical products often have to deal with fluctuations in overall demand from customers as well as the type of product. This leads to higher inventory costs, waste material due to change-overs and loss of productive capacity due to change-overs.
The reader will learn about typical challenges in production planning and key features of planning the production of different chemical products in a fixed facility. The reader will learn how to optimize production scheduling, sequencing and levelling of inventory in order to reduce waste and improve overall plant utilization.

Key Messages
- SMEs manufacturing chemical products often have to deal with fluctuations in overall demand from customers as well as the type of product. This leads to higher inventory costs, waste material due to change-overs and loss of productive capacity due to change-overs.
- Causes of chemical inflexibility include chemical contamination and unintended chemical conversions.
- Consequences of waste include waste material, loss of productive capacity, extra costs related to cleaning and changeover activities
- The product wheel is a management technique to minimize waste resulting from chemical transitions by production planning and scheduling (optimization).
