Abstract:

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. Following the modularization concept resulted in no more 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.
