OPTIMAL DESIGN AND OPERATION OF BATCH PROCESSES:

This paper discusses the formulation of the problem for the optimal design and operation of batch processes. The batch problem differs from the continuous one in a number of important ways. First, batch plants do not operate at steady state. There are important trade-offs between the processing time and the severity (intensity) of processing in ...

Batch processing - Wikipedia

History. The term "batch processing" originates in the traditional classification of methods of production as job production (one-off production), batch production (production of a "batch" of multiple items at once, one stage at a time), and flow production (mass production, all stages in process at once).. Early history. Early computers were capable of running only one program at a time.
