24/07/1997  The problem addressed is a general batch and continuous process scheduling problem, thus the model leads to a large scale MINLP, which is solved as an iterative sequence of MILPs, based on local linearization of the functions involved. The resource-task network concept is employed under which a mixed production facility is modeled as a collection of facilities performing a variety of tasks ...

Scheduling (production processes) - Wikipedia

Batch production scheduling is the practice of planning and scheduling of batch manufacturing processes. See Batch production. Although scheduling may apply to traditionally continuous processes such as refining, it is especially important for batch processes such as those for pharmaceutical active ingredients, biotechnology processes and many specialty chemical processes. Batch production scheduling shares some concepts and techniques with finite capacity scheduling which has been applied to many manufa

Operating System Scheduling algorithms

Priority Based Scheduling. Priority scheduling is a non-preemptive algorithm and one of the most common scheduling algorithms in batch systems. Each process is assigned a priority. Process with highest priority is to be executed first and so on. Processes with same priority are executed on first come first served basis.
