Breakdowns, gear failure, outages and different store ground disruptions can lead to massive losses for a company. Manufacturing managers are tasked with guaranteeing that factories and different manufacturing strains are getting probably the most worth out of their gear and programs.
Total gear effectiveness (OEE) and whole efficient gear 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 apparatus and manufacturing strains.
What’s general gear effectiveness (OEE)?
OEE is a metric used to measure the effectiveness and efficiency of producing processes or any particular person piece of apparatus. It offers insights into how nicely gear is utilized and the way effectively it operates in producing items or delivering providers.
OEE measures the gear effectivity and effectiveness based mostly on three elements. The OEE calculation is straightforward: availability x efficiency x high quality.
What’s whole efficient gear efficiency (TEEP)?
TEEP can also be a metric utilized in manufacturing and manufacturing environments to measure the general effectivity and effectiveness of apparatus or a manufacturing line. It consists of all of the potential manufacturing time, together with deliberate and unplanned downtime.
TEEP is calculated by multiplying four factors: 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 share of deliberate manufacturing time that’s productive, TEEP measures the share of all time that’s productive.
It’s necessary when making these calculations of time to make use of the suitable terminology. Listed here are just a few frequent methods to measure time inside a manufacturing context:
- Unscheduled time: Time when manufacturing will not be scheduled to provide something (versus “scheduled time”).
- Calendar time: The period of time spent on a job order as much as its completion.
- Whole operations time: The whole period of time {that a} machine is accessible to fabricate merchandise.
- Ideally suited cycle time: The theoretical quickest potential time to fabricate one unit.
- Run time: The time when the manufacturing course of is scheduled for manufacturing and working.
OEE primarily focuses on the utilization of accessible time and identifies losses attributable to availability, efficiency and high quality points. It helps establish areas for enchancment and effectivity optimization.
TEEP, then again, offers a broader perspective by contemplating all potential manufacturing time, together with deliberate downtime for preventive maintenance or changeovers. It goals to measure the utmost potential of the gear or manufacturing line.
OEE is usually used to measure the efficiency of a selected piece of apparatus or a machine. It helps you perceive how successfully gear is being utilized throughout precise manufacturing time. OEE is usually used as a benchmarking instrument to trace and enhance gear 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 apparatus working collectively. It offers a holistic view of the effectiveness of the complete system. In case you are interested by 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 could be useful in manufacturing capability planning and figuring out the capabilities of your gear 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 gear inside your manufacturing line. OEE evaluation helps pinpoint the causes of losses and inefficiencies on the gear stage. A digital asset administration platform can present real-time information to assist with this calculation.
- Determine bottlenecks: Use OEE information to establish bottlenecks or areas the place gear efficiency is suboptimal. Search for machines with decrease OEE scores and examine the underlying points. This might help you prioritize enchancment efforts and goal particular machines or processes which have probably the most vital impression on general efficiency.
- Consider TEEP for the complete line: Upon getting assessed the OEE for particular person machines, calculate the TEEP on your total 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.
- Examine OEE and TEEP: Examine the OEE and TEEP information to realize insights into the hole between precise efficiency and the utmost potential efficiency of the manufacturing line. Determine the elements contributing to the distinction between the 2 metrics, akin to scheduled upkeep, changeovers or different deliberate downtime. This comparability might help you perceive the general effectivity and effectiveness of the manufacturing line.
- Tackle frequent points: Analyze frequent points recognized by means of OEE and TEEP evaluation and devise methods to deal with them. This may increasingly contain enhancing machine reliability, procuring new gear, integrating steady enchancment methodologies, decreasing setup or changeover instances, enhancing product high quality or optimizing upkeep administration. Implementing focused enchancment initiatives might help bridge the efficiency hole and maximize the general gear efficiency.
- Observe progress over time: Constantly monitor and monitor each OEE and TEEP metrics over time to evaluate the effectiveness of your enchancment efforts. Commonly evaluating these metrics means that you can measure the impression of applied modifications and establish new areas for optimization.
By combining OEE and TEEP, you possibly can conduct a complete evaluation of present gear efficiency at each the individual-machine and production-line ranges. This built-in strategy offers a deeper understanding of efficiency elements, helps prioritize enchancment efforts, and maximizes the general effectiveness and effectivity of your manufacturing operations, permitting manufacturing managers to realize larger throughput and most uptime.
