Abstract

Abstract : Depuis de nombreuses années, le concept du Lean Six Sigma s’est largement implanté dans l’industrie mondiale. Les mécanismes proposés par cette doctrine ont fait l’objet de nombreux travaux scientifiques et de recherche. Dans le cadre de ce travail de fin d’étude, je propose à mes lecteurs d’aborder la question sous un angle différent, à savoir : « comment appliquer les outils du Lean Six Sigma afin de fluidifier un processus supply chain ? ». 
L’analyse s’effectue par le biais de la réalisation d’un projet Green Belt au sein de la société Safran Aero Boosters (anciennement Techspace Aero) appartenant au groupe Safran. Au moyen d’actions et de réflexions effectuées en équipe et au travers de l’approche structurée DMAIC , nous avons fluidifié la procédure de livraison directe d’un fournisseur 1 vers un fournisseur 2 pour un composant précis, assez basique pour servir de modèle à d’autres développements futurs. 
La rigueur, la rapidité, la souplesse, la pugnacité, l’implication des agents opérationnels concernés et de l’encadrement, l’esprit de groupe et le réel intérêt porté au cas pointé sont les principaux adjuvants mis en avant par cette étude. Ceux-ci témoignent de l’intérêt pour le Lean Six Sigma d’être vu non pas seulement comme un outil mais comme une méthode de travail efficace à appliquer au quotidien.

Abstract

In this project-thesis, we study the material overconsumption from Shur-Lok International, a subsidiary company from the PCC group. We use the DMAIC (Define, Measure, Analyse, Improve and Control) project management technique combined to the 7 basic quality tools for processes improvement in order to conduct our approach. Quickly, the company’s poor data quality prevents us from going further. As a result, we decide to take a step back from the original project in order to improve the data quality.
Thus, we represent the company’s processes using flowcharts in order to identify the steps at which the data quality is corrupted. Afterwards, we use the FMEA (Failure Mode Effects Analysis) technique to get a priority list from the failure mode’s risk priority number. 
Once the failure modes with a risk priority number above the acceptable threshold are identified, we define guidelines to prevent the failure modes to occur. The guidelines are built in association with the manufacturing workforce in order to come up with practical solutions. We had the opportunity to implement some of these guidelines and, as planned, they appear to improve the company’s data quality concerning the material overconsumption.
Afterwards, we explain how the material overconsumption study should be resumed once the company will obtain reliable data. Finally, we present our beliefs regarding the impact of the data quality improvement on the analysis and we explain why it is important for the company to carry on these improvements and the study of material overconsumption.

Abstract

Customer satisfaction has become a norm: product quality, on-time delivery and competitive prices are prerequisites for long-term business relationships.
The projects exposed in this thesis aim to advance the issue of non-compliance with deadlines identified in an aeronautical company, Britte-Mustad, by improving its production processes through the DMAIC methodology. 
The first project intends to improve the transmission of information on the arrival of workpieces in the various sectors of the workshop. The suggested solution to achieve this goal is the implementation of a table inspired by the Kanban method of the Lean production system. This thesis studies the implementation as well as the problems encountered such as resistance and change management as well as how to deal with them. 
The second project aims to improve the protection and identification of workpieces in order to reduce the risk of alteration during the manufacturing process. The considered solution consists in the acquisition of new packaging for the internal transport of workpieces. This thesis presents a comparative study of the solutions proposed by suppliers and describes the steps followed to lead to decision-making.
For the company, both studies must be the beginning of a series of projects following the same approach to achieve concrete results.

Abstract

After multiple fruitless attempts at creating performance management tools allowing to assess its
performance towards major corporate objectives, Brunswick Marine in EMEA, regional
headquarters of the American firm Mercury Marine, decided to get an external perspective on the
topic.
This project thesis report is the result of a project aiming at improving Brunswick Marine in
EMEA’s Strategic Performance Management System. The aim of the project was to define a
process for strategic performance management in the company, while making use of Business
Intelligence tools for effective reporting and automation.
Indeed, its previous tools were abandoned relatively rapidly due to their lack of integration in the
company’s standard performance review processes and their complex maintenance.
Following a Lean Six Sigma project management approach, a standard theoretical process for
Strategic Performance Management was first defined. This process was then used as a reference
to both identify the root causes of the previous models’ failures and prioritize our solutions.
Based on this analysis, strategy communication models were built to allow the company to cascade
its strategy into objectives that would rationalize the choice of Key Performance Indicators. Some
of the identified metrics were then implemented in Microsoft Power BI to showcase the benefits
offered by the tool to the whole process.
The resulting process from the proof of concept developed during the project would help the
organization have a transversal perspective on business performance and turn data into knowledge,
fostering decision-making.

Abstract

This book is intended to be a textbook for advanced undergraduate students, graduate students in engineering, and mid-career engineering professionals. It can also be a reference book, or be used to prepare for the Six Sigma Green Belt and Black Belt certifications by organizations such as American Society for Quality. The book focuses on the introduction of the basic concepts, processes, and tools used in Lean Six Sigma. A unique feature of this book is the detailed discussion on Design for Six Sigma aided by computer modeling and simulation. The authors present several sample projects in which Lean Six Sigma and Design for Six Sigma were used to solve engineering problems or improve processes based on their own research and development experiences in engineering design and analysis.

Abstract

Most real-world search and optimization problems naturally involve multiple criteria as objectives. Generally, symmetry, asymmetry, and anti-symmetry are basic characteristics of binary relationships used when modeling optimization problems. Moreover, the notion of symmetry has appeared in many articles about uncertainty theories that are employed in multi-criteria problems. Different solutions may produce trade-offs (conflicting scenarios) among different objectives. A better solution with respect to one objective may compromise other objectives. There are various factors that need to be considered to address the problems in multidisciplinary research, which is critical for the overall sustainability of human development and activity. In this regard, in recent decades, decision-making theory has been the subject of intense research activities due to its wide applications in different areas. The decision-making theory approach has become an important means to provide real-time solutions to uncertainty problems. Theories such as probability theory, fuzzy set theory, type-2 fuzzy set theory, rough set, and uncertainty theory, available in the existing literature, deal with such uncertainties. Nevertheless, the uncertain multi-criteria characteristics in such problems have not yet been explored in depth, and there is much left to be achieved in this direction. Hence, different mathematical models of real-life multi-criteria optimization problems can be developed in various uncertain frameworks with special emphasis on optimization problems.
