Demand shuffle - a novel method for multi-level proportional lot sizing and scheduling

Kimms, Alf - 1994

This contribution acquaints the reader with a model for multi-level single-machine proportional lot sizing and scheduling problems (PLSPs) that appear in the scope of short-term production planning. It is one of the first papers that deals with dynamic capacitated multi-level lot sizing and...

Multi-level, single-machine lot sizing and scheduling: With initial inventory

Kimms, Alf - 1993

This paper presents a mixed-integer program for the dynamic lot sizing and scheduling problem in a multi-level, single-machine environment. It turns out that in contrast to single-level problems the integration of initial inventory is a crucial aspect if generality should not be lost. It is...
