A modified framework for modelling set-up carryover in the capacitated lotsizing problem

In this note, a modified framework to model set-up carryovers in the capacitated lotsizing problem is presented. The proposed framework allows product dependent set-up times and costs to be incorporated. This is an extension of an earlier published work on modelling set-up carryovers for the constant set-up time scenario. An example to illustrate the modified framework is also provided.
