Abstract
We investigate the production planning and detailed scheduling of multiple-stage flexible flow shops, making products that require different production cycles. The production process can be configured in several ways, involving both different processing phases and times, depending on specific treatments required by the processed job. Jobs require operations on a unique raw material item and its quality features can require specific processing phases as well as lead to different processing times. We investigate, through the succession of a MILP and a CP model, the impact of quality-related aspects on processing times and hence on the overall planning and scheduling problem. An actual case from a leather tannery industry derived from the M2H - Machine To Human" (project code CBYX592), INNONETWORK 2017, Regione Puglia is investigated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
