Abstract

We consider the problem of minimizing makespan in a no-wait flowshop with an arbitrary number of machines. A lot consists of many identical items of the same product. Lot streaming (lot sizing) is the process of creating sublots to move the completed portion of a production sublot to downstream machines so that operations will be overlapped. We consider the number of sublots as given. We sho how, for any given machine (unit) processing times, we can (polynomially) compute the optimal lots sizes which minimize makespan.
