Welcome toTake Five with Automation World. I’m David Greenfield, Director of Content, and today we’re going to explain why the overall equipment effectiveness metric, typically referred to as OEE, still matters to industry. One of the reasons for a discussion on why OEE still matters is that there are some in industry who are questioning the value of OEE and referencing it as some archaic metric with little value to today’s manufacturing operations.
To start, I’ll note that what most OEE detractors point to is the fact that OEE can’t tell you how to fix an equipment issue. But it does show you where problems exist and is often an important metric for other technologies that can direct you in fixing specific problems. With that said, it’s important to realize what OEE is, as it’s never really been positioned—on its own—as a cure-all to equipment downtime.
取而代之的是，这是一个基于三个因素的设备操作指标：设备可用性，这是设备运行时按计划的生产时间分配的特定资产；性能，这是资产乘以总产品或部分计数除以资产运行时间的理想周期时间；和质量，这是良好的部分或产品数量除以总数。因此，OEE的主要目标是突出潜在设备问题的领域，以帮助提高效率，降低停机时间和运营费用并最大程度地减少浪费。它仍然是核心制造指标，因为它能够将复杂的生产问题归结为相对简单的术语以推动连续改进。
According toLNS Analytics对制造商,OEE仍是三大指标, with more than half of manufacturing analytics leaders saying they track OEE, which puts OEE behind only net profit margin tracking and on-time delivery tracking as a key manufacturing business metric.
Hunter Industries, a manufacturer of irrigation and outdoor lighting equipment, has long monitored OEE, starting with spreadsheets before moving to theInductive Automation’sIgnition software platform in 2013. The company fuels its OEE calculations with real-time data from PLCs using a mix of automated and manual methods. The results are regularly served up to employees via visual dashboards on the plant floor, enabling them to monitor issues and make adjustments as needed.
Saint Gobain Sekurit, a manufacturer of glass glazing systems, is another strong proponent of OEE to measure and compare performance across its global factories, as well as for capacity planning. OEE is reported per shift and once daily drawing from the company’s MES system, along with some manual data entry. The company recently advanced its OEE reporting using石声s自动化数据收集和数据平台边缘allow remote access to OEE data about the performance of key manufacturing lines. These OEE metrics are not only used by plant floor personnel, they’re also accessible to managers in logistics, supply chain, and maintenance operations to help them focus on continuous improvement, whether that involves adjustments to spare parts inventory or addressing equipment reliability issues.
ForGlidewell牙科，a manufacturer of restorative dental devices, OEE is part of an end-to-end automation initiative. Glidewell calculates OEE with the support ofBeckhoff Automation的工业PC和TWINCAT3自动化平台。使用这些技术，Glidewell每15分钟在机器级别计算OEE，以推断整个生产线的数据。这些OEE计算有助于评估是否拒绝了多少零件，因为它产生了太多零件或以太高的校准运行。
At加拿大级联, a paper and pulp processor, OEE calculations are regularly performed at the individual machine and line level, but the metric is also used at the plant level to drive continuous improvement and keep its multiple sites focused on the same business goals. Cascades manages OEE through mostly manual processes with individual operators using a homegrown system to capture data from a variety of legacy platforms and an SAP ERP system to calculate scores. More recently, its OEE efforts are being enhanced by a project to holistically improve asset health across its 70 plants using Emerson Automation Solutions’ condition monitoring technologies.
