The logic of Manufacturing Resource Planning (MRP II) is usually implemented in production planning and control systems and therefore has a major impact on the performance of many real production systems. Much of what practitioners complain about, i.e. long lead times, high work-in-process, and...

The discrete lotsizing and scheduling problem for one machine with sequence-dependent setup times and setup costs is solved as a single machine scheduling problem, which we term the batch sequencing problem. The relationship between the lotsizing problem and the batch sequencing problem is...

The logic of Manufacturing Resource Planning (MRP II) which is implemented in most modern production planning and control systems does not provide any satisfying solutions for multi-level lot sizing, especially not, when capacity is scare. Moreover, lot size and sequence decisions are usually...
