Before i start doing anything on the problem, i made a literature survey and found these 2 papers. Introduction scheduling is broadly defined as the process of assigning a set of tasks to resources over a period of. This video shows how to solve a flow shop scheduling problem using johnsons algorithm. Scheduling task the scheduling problem, under consideration, is called flowshop scheduling where given a set of parts to be processed jobs and a set of machines for processing. Two types of arrival patterns static n jobs arrive at an idle shop and must be scheduled for work. The flow shop scheduling problem with bypass consideration can be interpreted as a generalization of the classical flow shop model which is more realistic and assumes at least one job does not visit one machine. So, unfortunately 1 its very difficult to schedule a custom job shop.
