Set-up Continuity in Tactical Planning of Semi-Continuous Industrial Processes
In most of production planning models developed in a hierarchical context at the tactical level setup changes are not explicitly considered. Its consideration includes decisions about the allocation and lot sizing of production, known as CLSLP problem. However the CLSLP problem does not account for set-up continuity, specially relevant in contexts with lengthy set-ups and where product families minimum run length are almost are similar to planning periods. In this work, a MILP model which accounts for this set-up continuity inclusion is modelled, solved and validated over a simplified real-case example.
