Flow shop scheduling with lot streaming. (English) Zbl 0682.90051
Summary: Lot streaming is the process of splitting a job into sublots so that its operations can be overlapped. This paper deals with the problem of minimizing the length of a flow shop schedule when lot streaming is invoked. We show when it is sufficient in the one-job model to use the same sublot sizes for all machines, and we analyze the use of equal-sized sublots as a heuristic procedure. Finally, we demonstrate some of the difficulties involved in the n-job problem.
