Abstract
Abstract

Increasing competition due to market globalization, product diversity and technological
breakthroughs stimulates independent automotive companies to collaborate in a supply
chain that allows them to gain mutual benefits. Especially the events of the past years
have shell-shocked even the most ardent industry participants – a crisis and the
following hard recovery. Not only the critical challenges in implementing process lean
with low cost and high quality, also critical to success is the ability to efficiently meet
stricter emissions and fuel economy standards escalating in most jurisdictions.

With all the factors working beneath the waves, supply chain management becomes the
core source of a company’s competitive advantages and even the trump of the entire
automotive industry’s success. A proper supply chain strategy provides financial returns
and other key factors superior to the old concepts which brought profits before but no
longer up to date now. Correctly design and effectively evaluate the supply chains, and
improve the supply chain structure dynamically over time, are the key methods for an
automotive company to survive and succeed in the volatile and critical automobile
industrial environment.

In this research work, based on the real case study in the automotive door system supply,
different supply chain scenarios are designed and corresponding performance
evaluations are made by applying different methods, namely the conventional model and
the integrated model with their corresponding algorithms.

With conventional model, the evaluation is done from different aspects, where the
chosen perspectives such as costs, flexibility, stability, and reliability are assessed
respectively for the multi-stage international supply chains. The data applied in this
model comes from real-case door module supply, and the evaluation results helps in the
decision making in localization process of that certain project.

To be able to evaluate more complicated supply chain scenarios in a more accurate and
efficient way, an integrated model is designed for the comprehensive performance
evaluation. Based on the fuzzy theory, a MDFIE (Multilevel Dynamic Fuzzy Integrated
Evaluation) algorithm is developed to assess the automotive supply chain performance.
With the real case of vehicle door system supply, a detailed index system is designed
based on a profound understanding of the automotive door supply chain. And with this
new method, supply chain scenarios with different outsource degree and integration
degree are evaluated and analyzed, a positive solution of deeper integration and
downstream task shifting in the automotive supply structure is concluded in the end.

In addition to the use in this research work, the integrated model, especially the index
system can be flexibly adjusted for other automotive supply chains under their special
interest and requirements. And with the MDFIE algorithm or other possible methods, the
model can also be further developed into user-friendly software or system for the normal
application. This software development is suggested for the further research.

Based on the researches done in this work, a new tier structure is proposed as well. A
mega system supplier which is defined as the new Tier 0,5 and other outsourced service
companies which are playing as the half tiers (tier 1,5/ 2,5…) are discussed in this work.
With all the theoretical researches and practical investigations, this new structure which Abstract

occupies the niche positions of supply chain is supposed to be benefiting the entire
automotive supply chain in many critical aspects, like the long lasting over capacity
problem and the coming E-mobility trend. Some other suggestions like the application of
RFID technology are also proposed for increasing the productivity and strengthen the
information flow along supply chain. In general, improving the entire automotive supply
chain performance, is the ultimate goal of supply chain management, which means
balancing all participators’ maximum profits and offering the highest market service
level. The realization of the proposals and concepts, is also supposed to be studied in the
further research.

Acknowledgements

The completion of this dissertation would have not been possible without the generous
help and valuable advices from many people.

First I would like to express my sincere gratitude to Prof. Dr.-Ing. Bernd Noche for his
guidance, expertise, time and patience throughout the course of my studies. His supports
helped me tremendously in every stage of the research work.

I am specially grateful to my family – my parents Tian Tiansheng and Deng Chun’e, and
my younger brother Tian Shen, whose love and encouragements give me a constant
source of inspiration and strength. For years they have been sharing my tears and
laughter, and giving me the most loving support in my life, and help me out whenever I
felt overwhelmed. Their love and understanding always inspire me to keep going.

I would also like to thank all the researchers, who have done so much amazing work,
from which I learnt so much in the field of supply chain and automotive industry.

My deep appreciation is also extended to company “Brose Fahrzeugteile GmbH Co.
Kommanditgesellschaft” and “Kirchhoff Automotive GmbH”, who have offered me the
valuable chance of working in the team and collecting industry practical experiences.
Thanks to the free access to all kinds of data, I am able to complete the dissertation with
the real case study. Special thanks to Mr. Hilmar Dohles from Brose, Mr. Arndt
Kirchhoff and Mr. Ludger Engels from Kirchhoff, and all my other team colleagues.

I also want to thank my faculty colleagues who spent a lot of precious time with me, and
helped me in the literature searching, software studying, and made their efforts in every
possible aspect. Special thanks to Mr. Zhu Taobo, Mr. Sun Yongxin and Mr. Weng
Weibing, their supports helped me avoiding a lot of mistakes and detours.

Last but not least, I would like to express my great thanks to my dear friends, who have
been all the time encouraging me during the long time in Germany. To Mr. Liu Yan,
Mrs. Yang Hui, and all my dear friends, I would like to say a sincere Thank You.
