Breakdowns, gear failure, outages and different store ground disruptions may end up in massive losses for a corporation. Manufacturing managers are tasked with making certain that factories and different manufacturing traces are getting essentially 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 bettering the efficiency of kit and manufacturing traces.
What’s total gear effectiveness (OEE)?
OEE is a metric used to measure the effectiveness and efficiency of producing processes or any particular person piece of kit. It gives insights into how properly gear is utilized and the way effectively it operates in producing items or delivering companies.
OEE measures the gear effectivity and effectiveness based mostly on three components. 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 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 share of deliberate manufacturing time that’s productive, TEEP measures the share of all time that’s productive.
It’s essential when making these calculations of time to make use of the proper terminology. Listed here are just a few widespread 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 whole period of time {that a} machine is out there 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 working.
OEE primarily focuses on the utilization of obtainable time and identifies losses on account of availability, efficiency and high quality points. It helps establish areas for enchancment and effectivity optimization.
TEEP, however, gives 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 gear or manufacturing line.
OEE is usually used to measure the efficiency of a selected piece of kit 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 kit working collectively. It gives a holistic view of the effectiveness of your complete system. In case you are concerned with 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 may 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 knowledge to assist with this calculation.
Determine bottlenecks: Use OEE knowledge to establish bottlenecks or areas the place gear efficiency is suboptimal. Search for machines with decrease OEE scores and examine the underlying points. This will help you prioritize enchancment efforts and goal particular machines or processes which have essentially the most important influence on total efficiency.
Consider TEEP for your complete line: After you have assessed the OEE for particular person machines, calculate the TEEP to your complete manufacturing line. TEEP takes into 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 achieve 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 will help you perceive the general effectivity and effectiveness of the manufacturing line.
Deal with widespread points: Analyze widespread points recognized by way of OEE and TEEP evaluation and devise methods to handle them. This may occasionally contain bettering machine reliability, procuring new gear, integrating steady enchancment methodologies, decreasing setup or changeover occasions, enhancing product high quality or optimizing upkeep administration. Implementing focused enchancment initiatives will help bridge the efficiency hole and maximize the general gear efficiency.
Monitor progress over time: Constantly monitor and observe each OEE and TEEP metrics over time to evaluate the effectiveness of your enchancment efforts. Often evaluating these metrics permits you to measure the influence of carried out adjustments and establish new areas for optimization.
By combining OEE and TEEP, you’ll be able to conduct a complete evaluation of present gear efficiency at each the individual-machine and production-line ranges. This built-in method gives 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 realize increased throughput and most uptime.
