Abstract
This paper aims to evaluate the solution behaviour of the “Overall Equipment Effectiveness” to determine the performance in innovative manufacturing environments. OEE literature categorizes six major losses: “Equipment failures and breakdowns”, “Setup/Adjustments”, “Idling and minor Stops”, “Reduced Speed Losses”, “Reduced Yields and Quality Defects and Rework”. The technical implementation method used by the authors to achieve their scope has been described using a hybrid of software development programs such as: SAP MII, SAP PCo and SAP ME in relation to the theoretical existing principles. The results presented conclude that losses in practice can occur at both high rates and low rates and therefore, an innovative manufacturing concept must be further enhanced. In terms of performance related to equipment utilization, the specific stoppages and downtimes need to be taken in consideration and adjust the OEE results accordingly. The actual situation in a real–life environment has increased in efficiency, but as technology improves, opportunities for further development appear at a high rate.

This paper aims to evaluate the solution behaviour of the “Overall Equipment Effectiveness” to determine the performance in innovative manufacturing environments
An important layer of the methodology is described with the product from SAP named “Plant Connectivity” (PCo)
The software is used in this case study as a set of tools that will exchange the data between the OEE system and the actual physical system represented by the equipment and machines. The implementation using this type of software relies on the fact that the equipment sends the data as a source system towards the PCo system, which will be connected to the OEE system
Summary
OEE (“Overall Equipment Effectiveness”) has been defined in literature as being the tool used to measure the equipment performance in the manufacturing industry. Performance indicates the speed at which the physical machines is producing parts in a daily shift This is defined as being a quantitative indicator of which takes in consideration the actual amount of parts produced compared to the capacity of the equipment in an ideal environment. Quality refers to the actual accepted quantity of finished goods produces from the total amount of raw material in the actual machine time shift of the day. This topic can be further elaborated with new and improved sophisticated solutions and error-inspection steps that can present the quality performance in the actual machine. OEE defines the production time of quality accepted pieces of finished goods divided by the shift time
