Sammanfattning
This thesis presents a case study conducted at Paulig, a food production company in
Gothenburg, Sweden, with the purpose of examining how productivity and the
availability factor in the Overall Equipment Effectiveness (OEE) metrics can be
increased when focusing on setup times. The examined research questions are “How
can the availability factor in OEE measurements be increased when focusing on
downtimes?”, “How can setup times be reduced?”, and “How can standardized setup
processes be attained?”
Six setup cases were identified and extensively analyzed, improved, and standardized
using spaghetti diagrams, work classification, Single Minute Exchange of Die (SMED),
and work instructions. Collaboration with operators and informal interviews with both
operators and the management team played a crucial role in the improvement process.
The first research question aimed to determine how the availability factor could be
increased by focusing on downtimes. The answer revealed that reducing setup time
could effectively minimize planned production downtimes. The answer to the second
research question is that Spaghetti diagrams, work classification, and SMED analyses
can together be used to reduce setup times. The third research question focused on how
standardized setup processes can be attained. The result showed that providing clear
instructions to operators can contribute to the standardization of setup processes. In
conclusion, this thesis highlights that spaghetti diagrams, work classification, SMED
analyses, and work instructions can be combined to increase productivity and the
availability factor at a production line.
