Breakdowns, tools failure, outages and different store flooring disruptions can lead to huge losses for a company. Manufacturing managers are tasked with making certain that factories and different manufacturing traces are getting essentially the most worth out of their tools and programs.
General tools effectiveness (OEE) and whole efficient tools efficiency (TEEP) are two associated KPIs which are utilized in manufacturing and manufacturing environments to assist forestall losses by measuring and enhancing the efficiency of kit and manufacturing traces.
What’s total tools effectiveness (OEE)?
OEE is a metric used to measure the effectiveness and efficiency of producing processes or any particular person piece of kit. It offers insights into how effectively tools is utilized and the way effectively it operates in producing items or delivering companies.
OEE measures the tools effectivity and effectiveness based mostly on three components. The OEE calculation is easy: availability x efficiency x high quality.
What’s whole efficient tools efficiency (TEEP)?
TEEP can be a metric utilized in manufacturing and manufacturing environments to measure the general effectivity and effectiveness of kit or a manufacturing line. It contains all of the potential manufacturing time, together with deliberate and unplanned downtime.
TEEP is calculated by multiplying 4 components: availability x efficiency x high quality x utilization.
How are OEE and TEEP completely different?
The primary distinction between these two metrics is that whereas OEE measures the proportion of deliberate manufacturing time that’s productive, TEEP measures the proportion of all time that’s productive.
It’s necessary when making these calculations of time to make use of the precise terminology. Listed here are a number of frequent methods to measure time inside a manufacturing context:
- Unscheduled time: Time when manufacturing shouldn’t be scheduled to provide something (versus “scheduled time”).
- Calendar time: The period of time spent on a job order as much as its completion.
- Complete operations time: The overall period of time {that a} machine is accessible to fabricate merchandise.
- Ideally suited cycle time: The theoretical quickest attainable time to fabricate one unit.
- Run time: The time when the manufacturing course of is scheduled for manufacturing and operating.
OEE primarily focuses on the utilization of accessible time and identifies losses resulting from availability, efficiency and high quality points. It helps establish areas for enchancment and effectivity optimization.
TEEP, however, offers a broader perspective by contemplating all potential manufacturing time, together with deliberate downtime for preventive upkeep or changeovers. It goals to measure the utmost potential of the tools or manufacturing line.
OEE is usually used to measure the efficiency of a particular piece of kit or a machine. It helps you perceive how successfully tools is being utilized throughout precise manufacturing time. OEE is often used as a benchmarking instrument to trace and enhance tools efficiency over time. It helps establish bottlenecks, areas for optimization and enchancment initiatives.
TEEP is used to measure the general efficiency of a complete manufacturing line or a number of items of kit working collectively. It offers a holistic view of the effectiveness of the complete system. In case you are eager about understanding the utmost potential efficiency of your manufacturing line, together with deliberate downtime for upkeep, changeovers or different scheduled occasions, TEEP is the efficiency metric to make use of. TEEP might be useful in manufacturing capability planning and figuring out the capabilities of your tools or manufacturing line.
How can OEE and TEEP be used collectively?
- Begin with OEE evaluation: Start by calculating the OEE for particular person machines or tools inside your manufacturing line. OEE evaluation helps pinpoint the causes of losses and inefficiencies on the tools stage. A digital asset administration platform can present real-time knowledge to assist with this calculation.
- Determine bottlenecks: Use OEE knowledge to establish bottlenecks or areas the place tools efficiency is suboptimal. Search for machines with decrease OEE scores and examine the underlying points. This can assist you prioritize enchancment efforts and goal particular machines or processes which have essentially the most vital influence on total efficiency.
- Consider TEEP for the complete line: Upon getting assessed the OEE for particular person machines, calculate the TEEP in your whole manufacturing line. TEEP takes under consideration all potential working time—together with deliberate and unplanned downtime—offering a broader perspective on the general efficiency of the road.
- Evaluate OEE and TEEP: Evaluate the OEE and TEEP knowledge to realize insights into the hole between precise efficiency and the utmost potential efficiency of the manufacturing line. Determine the components contributing to the distinction between the 2 metrics, resembling scheduled upkeep, changeovers or different deliberate downtime. This comparability can assist you perceive the general effectivity and effectiveness of the manufacturing line.
- Handle frequent points: Analyze frequent points recognized via OEE and TEEP evaluation and devise methods to deal with them. This will likely contain enhancing machine reliability, procuring new tools, integrating steady enchancment methodologies, lowering setup or changeover occasions, enhancing product high quality or optimizing upkeep administration. Implementing focused enchancment initiatives can assist bridge the efficiency hole and maximize the general tools efficiency.
- Monitor progress over time: Constantly monitor and monitor each OEE and TEEP metrics over time to evaluate the effectiveness of your enchancment efforts. Recurrently evaluating these metrics means that you can measure the influence of carried out modifications and establish new areas for optimization.
By combining OEE and TEEP, you possibly can conduct a complete evaluation of present tools efficiency at each the individual-machine and production-line ranges. This built-in strategy offers a deeper understanding of efficiency components, helps prioritize enchancment efforts, and maximizes the general effectiveness and effectivity of your manufacturing operations, permitting manufacturing managers to attain increased throughput and most uptime.
