This master thesis has been carried

This master thesis has been carried out at Volvo Trucks in order to answer the question “how
will line balance efficiency change when following a modularization concept with fishbone
layout instead of doing lots of different tasks in the main assembly line?” Currently a lot of
different tasks are made in the main assembly line which due to the high product variety
causes line balance efficiency losses. In order to do this study, a concept of modularization in
production with a fishbone layout has been studied. This concept has been modeled with
discrete event simulation in order to find the balance efficiency in the final assembly. The
current final assembly has also been modeled in order to find out the line balance efficiency in
production today.
The result of the DES-models of modularization concept shows high task variation in each
fishbone. This model considers different scenarios and layouts for managing the fish bones
e.g. average balancing, maximum balancing, serial line layout and parallel station layout in
each fishbone. Based on the results of this study, following the modularization concept caused
no increase on line balance efficiency losses. However, the improvement in line balance
efficiency depends on the considered scenario. The result of each scenario differs from each
other which led to the conclusion that the line balance efficiency in this modularization
concept is highly dependent to the way each fishbone is organized and managed. The given
possibility from the modularization concept to manage each fishbone separately and in
different ways is concluded as the most important finding from this study.
