Determining the Potential to Improve Schedule Compliance

High schedule compliance is very important but rarely achieved in make-to-order productions. Especially when orders are released too late (e. g. due to missing raw material) it is challenging to identify how many orders can still be produced in time. This paper shows how companies can identify their potential to increase schedule compliance by earliest operation due-date sequencing. The simple model shows that five parameters determine the potential to increase schedule compliance through sequencing: the input sequence deviation, the WIP level, the number of operations, planned sequence interchanges in the order throughput, and the number of parallel machines.
