Visualisering av produktionseffektivitet : Utveckling av ett verktyg för övervakningav avbrott och presentation av TAK

Sammanfattning: Many companies do not register all the stops that occur in a production plant, it often takes longer to report than to fix the problem. If no problems are registered, you cannot trace where the problems arise. This master thesis was performed at AcobiaFLUX and they have noticed an increased demand from their customers to trace problems raised in their processes. The aim of the thesis was to find out how a tool to monitor a process best could be developed. Then the most essential from the theoretical base was developed into a useful tool for operators. For the operators to know if the process utilizes the full capacity of a process, the tool presents a measure of the Overall Equipment Efficiency, OEE. OEE is calculated by  ultiplying availability, performance and quality. Availability indicates how much time the  quipment is used for production. Performance indicates how efficient production is in terms of production speed. Quality indicates how many products that have been approved. In order for a tool that monitors processes and present production efficiency to be helpful it must be easy and intuitive for the user. To make an easy and intuitive tool for operators some Human-Computer-Interaction guidelines where used. The tool is not the primary  orkspace for an operator and therefore the use of the tool need to be minimized so it will not steal the operator’s time. To become a tool for tracing problems in processes, all operators need to participate and use the tool properly, otherwise you cannot compare if the production efficiency has been improved.
