OEE productivity and overall efficiency
Measures OEE productivity and overall machine and operator efficiency with OEE indicators of overall production efficiency.
The OEE doeet (Overall Equipment Effectiveness) system collects all the data of the indicators of OEE productivity of your production lines and perform the necessary calculations to obtain the OEE values. OEE, availability, performance and quality, their deviation from their target value and their evolution over time.
- Analyze with the productivity indicators any incident occurred during the manufacturing process.
- Know at a glance the OEE, availability, performance and quality of your production in real time.
- Filter all data by line, reference, order or shift to know the causes of productivity decrease.
Know your OEE productivity indicators
The OEE is the average of the productivity, availability, performance and quality indicators of the production lines. The OEE graphs reflect any major issues that occurred during manufacturing.
The OEE doeet system allows you to specify a target value for OEE productivity indicators for each line, shift or reference. Targets are taken as a reference to measure the deviation of an indicator with respect to the expected value. The doeet system uses this information to provide informative and visual indications when OEE productivity indicators deviate from their targets.
Analyze the evolution of your OEE productivity KPIs
Know exactly which of the OEE global productivity indicators is affecting your company’s production efficiency and when it occurs.
Analyze the actual evolution of the OEE global productivity indicators calculated by doeet from the data captured by the in-plant MES system and the availability, performance and quality indicators, and compare them with the targets configured in the doeet system.
In this way we can quickly find out whether the drop in overall productivity is due to availability, performance or quality problems.
Your OEE productivity by line, by shift or by reference
doeet can filter the information collected by lines, references, production orders, shifts, in order to delve deeper into the causes of the productivity drop. We can also customize the time period of the data collected in the Report: today, yesterday, current week, previous week, month.
This analysis allows us to quickly determine whether a drop in the OEE productivity indicator is a global production problem or a specific problem in one of our lines. This information is important for the analysis of our production efficiency.
But what is OEE?
OEE (Overall Equipment Effectiveness) is a percentage ratio used to measure the overall efficiency and productivity of industrial machinery and gives us the keys on how to calculate productivity.
OEE productivity indicators are an international standard recognized by major industries around the world.
The advantage of OEE is that it encompasses the fundamental parameters of industrial production in a single indicator. By analyzing these three parameters, we can determine whether what is missing to reach 100% productivity is due to availability, performance or quality.
Learn how to calculate overall productivity using OEE in this article.
Availability
Machine and operator availability is calculated by dividing the time the machine has been producing(operating time) by the time the machine could have been producing and did not.
The time that the machine could have been producing(planned production time) is obtained by subtracting from the total production time the periods in which it was not planned to produce.
Performance
The yield or production efficiency is obtained by dividing the number of parts actually produced by the number of parts that could have been produced.
The number of parts that could have been produced is obtained by multiplying the production time by the production capacity or speed of the machine.
Quality
The production quality is obtained by subtracting the defective parts discarded in the quality controls from all the parts manufactured. Quality losses involve both the cost of energy and raw materials and the loss of production time, the time taken to manufacture the defective units.
They may also include reprocessing time or the cost of disposing of or recycling defective units.
Availability losses (B)
Machines are idle for too long: product changeover, breakdowns, no work order, no raw material.
Yield losses (D)
Machines do not run at the desired speed: Low speeds due to problems with raw material, snagging, micro stoppages, lack of machine adjustment.
Quality losses (F)
Too many defective parts are manufactured: defective raw material, poor machine adjustment, lack of Quality Control.
