Tiivistelmä
The purpose of this Master’s Thesis was to examine the material flow of a car contract manufacturer’s new body welding process. The company is planning a new body shop for a new car model coming into production. The goal is to evaluate if the new body welding process is sufficient and to find solutions to reach target values.
The research methods used in this Master’s Thesis were familiarization with the production system, simulation study, open survey and getting acquainted with process documents. The study also examined previous written literature and articles and researches that were dealing with the subjects covered in this thesis. Research methods used were deemed sufficient to solve the research problems.
The thesis was commenced by getting acquainted with the overall production process. This was done by participating in work activities in the planning phase of the new body shop. The familiarization took part throughout the entire research and with it also open survey was used to gather material for the current state analysis and simulation study.
Simulation study was used to evaluate the new body welding process. Improvement areas were found and this study proposes solutions for these areas. The most important improvement proposal was building another finishing line.
All the proposed options and solutions were evaluated by using simulation study. The results were partly negative but the mostly positive. With the proposed solutions the new body welding process output was on target.
