This paper presents a comparative analysis of advanced manufacturing control systems using simulation. In particular, three PULL production philosophies have been analysed: a Just In Time (JIT), a CONstant Work In Process (CONWIP) and a hybrid system environments. These different production control philosophies have been applied to flow shop systems with four, six and eight machines, evaluating the manufacturing system performance (i.e. Service Rate, WIP, finished Goods, Time in System, Maximum Queue Size). The performances have been analysed both in an ideal case (machines efficiency equal to 100%) and in a real case (machines efficiency lower than 100%), so as to consider machine breakdowns. To overcome the limit of low performance in presence of a machine failure, two further solutions have been proposed, taking into account the introduction of kanban-break cards together with a re-allocation of workers during a machine downtime towards the upstream work centres.

Abstract
This paper presents a comparative analysis of advanced manufacturing control systems using simulation. In particular, three PULL production philosophies have been analysed: a Just In Time (JIT), a CONstant Work In Process (CONWIP) and a hybrid system environments. These different production control philosophies have been applied to flow shop systems with four, six and eight machines, evaluating the manufacturing system performance (i.e. Service Rate, WIP, finished Goods, Time in System, Maximum Queue Size). The performances have been analysed both in an ideal case (machines efficiency equal to 100%) and in a real case (machines efficiency lower than 100%), so as to consider machine breakdowns. To overcome the limit of low performance in presence of a machine failure, two further solutions have been proposed, taking into account the introduction of kanban-break cards together with a re-allocation of workers during a machine downtime towards the upstream work centres.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
