Styrkan i OEE som arbetsmetod
The E-department at GETRAG All Wheel Drive in Köping have problems with the efficiency on parts of their production equipment. The equipment with the most significant efficiency problems are four automated multifunctional production cells that produces housing for rear drive units. The major part of the problem is the large amount of small stops that causes the low efficiency.The department already worked with logging of interruptions and efficiency calculations before this project started. However this work was not done to the extent considered necessary for a systematic follow-up of the interruptions.The aim of this paper is to point out a more effective and systematic way to work with logging of interruptions and the follow-up. In addition the equipment were studied with a method for efficiency calculation that ? if used properly- is a more powerful and a visually better method than the one used by the company today.As the initial current state analysis of the equipment was made a lack of documented knowledge about the equipment was discovered. In addition the efficiency appeared to be lower than the companies previously presented figures.With the help of new methods for logging of interruptions and a deeper failure analysis the production equipment were studied for ten weeks. These studies showed that the department have big opportunities to a more effective and more profitable production. This can be done by reducing the chronicle interruptions through a more systematic work with continuous improvements.On the basis of the performed studies and the theoretical references a new working method that is based on the commitment of all employees is presented. This method can be used by the E-department to work with continuous improvements in a more systematic way than today.
