Scheduling model for multi-stage flow lines with zero lead times

摘要

Mathematical programming models for lot-sizing and scheduling to provide customers with practically useful due dates and reduce throughput times with minimum costs. In a multi-period multi-stage model with fixed led time can lead to unnecessarily planned lead times. This paper presents a model which works without a positive lead time offset while resulting in a feasible material flow throughout the planning horizon minimizing the setup, holding, and backordering costs. This model is suitable for consumer goods or pharmaceutical industry where the material between successive production-stages is delinked because of inventories of products at intermediate stages.
