For batch processes, which are predominant in the manufacture of specialty chemicals, Chapter 12 provides an introduction to the methods of optimizing the design and scheduling of these processes. Individual process units, combinations of reactors and separators, and multiproduct plants are considered. 

Puigjaner and co-workers in Chapter D2 explore the interactions between the various decisions levels linked to the batch control system. The work is motivated by the increasing shift in chemical industry to higher added value products that are usually produced batch-wise (Ref 1). Optimal design, analysis, and scheduling of batch processes lead to hierarchical and interconnected decision levels that require a holistic approach. A comprehensive overview of the requirements and standards for automatic batch control systems provides the basis for the... 

However, the designer should not loose sight of the fact that, whilst schedule planning and optimization provides the basis for the design of batch processes, production schedules are often disrupted once production has commenced. For example, what happens if a key item of equipment breaks down and needs to be repaired What happens if...
