This demo displays the front-end for the OEEE online calculator.

Presently, pure economic efficiency metrics guides the optimisation of vehicle manufacturing. However, manufacturing is a major consumer of energy. In order to support sustainability and facilitate interactions between actors in the supply chain, we have defined a new, total optimisation metrics by adding energy to the OEE index, thus creating a new key index, the OEEE Overall Equipment and Energy Efficiency index, with the following four components.

The OEEE index breaks the total performance of equipment into four separate and measurable components: Availability, Performance, Quality and Energy Efficiency:

• Availability looks at the downtime loss, which is the time the production is stopped, compared to the planned production time. Availability is a function of equipment failures, material shortages, and changeover time.
• The Performance component is also a function of downtime, changeover time and speed loss, i.e., factors that result in the process operating at less than maximum speed due to machine wear, misfeeds, and operator inefficiency.
• The Quality component depends on the amount of produced items that fails to meet quality standards and thus will have to be either rejected or reworked.
• The Energy component is a function of the actual energy efficiency of the real production process, i.e., how much energy is wasted compared to the most efficient process.

The diagram below illustrates how the new OEEE is determined:

Use the slides below to calculate the OEEE. First slide is for the availability index, next slide for the efficiency index, third slide for the quality indes and the bottom slide for the energy index. At the bottom the OEEE index is calculated.



In the real ebbits demonstrator, the data are automatically collected from the production line and the OEEE is dynamically calculated.
