The accurate evaluation of Overall Equipment Effectiveness (OEE) has to be considered both in system design for a correct estimation and in system management for a correct analysis. It could be critical because the value of OEE for a single machine depends on the system it has been introduced. Moreover OEE for a single machine and for whole system (named Overall Throughput Effectiveness OTE) are mutually influenced by efficiency losses propagation.

A simulation model has been developed to support the theoretical analysis and to show how simulation can facilitate OEE study, losses propagation understanding and the investigation of efficiency improvement opportunities in a real context.

Abstract
The accurate evaluation of Overall Equipment Effectiveness (OEE) has to be considered both in system design for a correct estimation and in system management for a correct analysis. It could be critical because the value of OEE for a single machine depends on the system it has been introduced. Moreover OEE for a single machine and for whole system (named Overall Throughput Effectiveness OTE) are mutually influenced by efficiency losses propagation. This paper aims to understand effects of efficiency losses propagation for correct estimation and analysis of OEE. A simulation model has been developed to support the theoretical analysis and to show how simulation can facilitate OEE study, losses propagation understanding and the investigation of efficiency improvement opportunities in a real context. In particular the paper presents some explanatory situation analyzed through a simulation model that has been developed on a real case of a manufacturing plant for production of electrical cable with a flow-shop process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
