Abstract:This research has been executed in response to the high inventory losses the company experienced. One of the root causes that is uncovered and what will be focused on during this research is the interplay between minimum batch sizes and demand volumes. It appears that products that were often affected by their batch size restrictions due to low demand volumes in comparison to their minimum brewing volumes, relatively encountered much more obsolescence. For this reason it is hypothesized that part of the obsolescence of these products could have been avoided by applying early disposal of semi-finished beer to these products. The model that is developed to tackle the earlier mentioned root cause is two-fold: a monitoring dashboard measures the expected obsolescence of products, where after the impact of early disposal of semi-finished beer on obsolescence is examined by an optimization tool. Besides early disposal, also a redivision of semi-finished beer over multiple end products is considered. In this way, the model aims to support decision-making regarding product obsolescence.
