The role of equipment flexibility in Overall Equipment Effectiveness (OEE)-driven process improvement

چکیده
In manufacturing and assembly operations, Overall Equipment Effectiveness (OEE) is a frequently used quantitative metric for measuring the overall productivity of single machine, cell or an integrated system. However, it does neglect typically even penalizes flexibility capabilities. Today’s customer needs highly customized products put these productivity-based measurements more under pressure. Frequent product changes on workstations result in lower availability through set-up, performance losses due to slower cycles learning-forgetting effect operators, start-up defects resulting frequent quality issues. A contradiction arises: modern production this becomes important as enabler mass customization paradigm, but difficult incorporate (or relation to) OEE figure trend conflicts with OEE-driven process improvement strategies. Consequently, can be argued that capabilities should embedded equipment effectiveness calculation. Modern cells have high mobility stable uniform across complete range products. This paper first highlights importance measurement facilitate paradigm try continuously improve towards resilient Next, heuristic framework Flexibility-included (OEEFlex) introduced, based three core indicators: mobility, uniformity range. The factors are introduced described. Links current frameworks made. approach new starts from long list variables possible calculation methods indicator values. Future research describes illustrative simulation scenarios filter short relevant valuable options metric. Followed by expert final selection case in-company validation result.
