A threshold-based control policy for scrap reduction of perishable in-process inventories

Sustainability has become a key factor for competitiveness. Sustainable production strategies aim at the scrap reduction of in-process inventory. In some sectors such as food or pharmaceutical sector, in-process inventories must be scrapped after a certain time due to perishability. Therefore, local policies are usually applied to machines in order to mitigate the impact of disruptive events leading to scrap.
