Lean production and Lean philosophy have been developed, studied and implemented over the world since it was know from Toyota Production System. International manufacturers/OEMs have more or less developed their own Lean production systems. Over the years, arising challenges from new technology and internationalization have force the OEMs to understand and evaluate the design of supply chain to support their lean production system, and to manage the SC and compete as a whole against other supply chains. When apply Lean principles to the level of Supply Chain, coordination is an essential element to success. Today, researches have been done on joint efforts on decision making among supply chain actors, and applying Lean tools such as VSM on an extended level, namely a supply chain. Whereas the methods to improve SC coordination when implementing Lean through SC remain undeveloped. By interviewing Lean supply chain experts, experienced personnel in Supply Chain Management, and Lean experts from various organizations, a methodology to identify and visualize the improvement areas in supply chain coordination was designed. The methodology was then tested in a European OEM’s supply chain. Value Stream Mapping, as the base, was adapted to support identification and visualization of improvement areas in supply chain coordination. Several misalignments in the SC coordination were found in the current state, then visualized in current state map and approved by various SC actors. The methodology was then improved according to the process of testing. The purpose of this thesis is to develop a methodology to identify and visualize the improvement areas in (manufacturing) supply chain coordination within a Lean perspective.

Endimensionell kod ska fasas ut som informationsbärare i dagligvarubranschen och ersättas med tvådimensionell kod, något som anses kunna leda till ett paradigmskifte enligt GS1. Syftet med studien är att analysera den potentiella påverkan ersättandet av endimensionell kod till tvådimensionell kod kommer ha på orderhanteringsprocessen i dagligvarubutiker. Förändringen antas i sin tur påverka andra processer i butik samt den direkta försörjningskedjan. Studien hade en induktiv ansats och information från GS1 har legat till grund för teorivalen. En digital intervju utfördes för att diskutera aktiviteter som sker i en orderhanteringsprocess. Resultatet från studien visade på att QR-koden i sig inte kommer skapa ett paradigmskifte, mycket kommer att bero på hur QR-koden implementeras och på vilket sätt organisationer drar nytta av informationen som blir tillgänglig. QR-kod (typ 3) kommer inte påverka de nuvarande aktiviteterna i orderhanteringsprocessen nämnvärt, men QR-koden har desto större potential att påverka aktiviteter som indirekt har kopplingar till orderhanteringen. Eftersom den tvådimensionella koden har kapacitet för mer information kan det potentiellt bidra till att varuflöden effektiviseras och att samtliga medlemmar i försörjningskedjan får tillgång till information som skapar affärsnyttor för både leverantör, butik och kund. / One-dimensional code will be phased out in the grocery industry and replaced with two-dimensional code, something that is considered to lead to a paradigm shift according to GS1. The purpose of the study is to analyze the potential impact the replacement of one-dimensional code to two-dimensional code will have on the order fulfillment process in grocery stores. The change is in turn assumed to affect other processes in the store as well as the direct supply chain. The study had an inductive approach, information from GS1 has been the basis for the theories chosen. A digital interview was conducted to discuss activities that take place in an order fulfillment process. The results from the study showed that the QR code itself will not create a paradigm shift, much will depend on what way organizations benefit from the information that becomes available. QR code will not significantly affect the current activities in the order fulfillment process, the QR code has greater potential to affect activities that are indirectly linked to order fulfillment. Two-dimensional code has the capacity for more information, it can potentially contribute to streamlining of product flows and contribute to business benefits for the members of the supply chain.

The purpose of this thesis is to design and implement tools for support of a snapshot and a rollback for configuration files on the GNU/Linux distribution. The set of the tools enables an automatic/periodical saving of the configuration files into the selected placement. The creation of backups reacts to file events by watching the changes with kernel subsystem inotify. Tools are enabling to return to the selected backup. The way of the backup actualization is configurable. This tool permits the data comparison from selected backups, to show the differences in configurations and eventually to manage a merge among actual and selected backup. Tools also allows a comparison of a configurations of one client or configurations among clients, and to display the mutual differences, eventually to manage their merge.

Gesellschaftliche Verantwortung (CSR) nimmt für Unternehmen bedingt durch steigenden Druck seitens verschiedener Stakeholder sowie veränderte gesellschaftliche Erwartungshaltungen und politische Rahmenbedingungen eine immer bedeutenderer Rolle im gesamten Wertschöpfungsprozess ein. CSR geht über die Unternehmensgrenzen hinaus und umfasst die mit dem eigenen Unternehmen verbundenen Leistungsersteller. Die Einkaufsfunktion übernimmt mit einem hohen Anteil am Wertschöpfungsprozess die wichtige Aufgabe, Leistungserstellung bei dritten Unternehmen (Lieferanten) einzukaufen. Häufig sind dies Lieferanten in Entwicklungs- und Schwellenländern mit teilweise stark abweichenden Produktionsbedingungen. Um fehlende Gesetze und nicht zertifizierbare Standards zu kompensieren, sind insbesondere große Unternehmen dazu angehalten, ihre Lieferantenbasis hinsichtlich CSR-Kriterien zu überprüfen und ein regelkonformes Verhalten sicherzustellen. Die vorliegende Dissertation verfolgt die Idee, die Notwendigkeit einer Integration von CSR als Bewertungskriterium in bestehende Prozesse zu untersuchen, um geeignete Lieferanten für eine strategische Beziehung bewerten zu können. Hierfür wird zunächst anhand von Experteninterviews die praxisorientierte Messmethode „CSR-IndexSA“ auf Basis einer Selbstauskunft entwickelt. Eine Überprüfung auf Reliabilität dieser Messmethode erfolgt mittels einer empirischen Erhebung bei einer hohen Anzahl von Zulieferunternehmen. Eine umfangreiche statistische Analyse bestehender Bewertungskriterien und -prozesse mit der erhobenen CSR-Performance dieser Lieferanten zeigt als Ergebnis eine notwendige eigenständige Integration von CSR als Bewertungskriterium mit einer nur geringen Auswirkung auf bestehende Prozesse. Anhand der empirischen Erhebung konnten desweiteren CSR-Risikofaktoren, wie Unternehmensgröße und Region bestätigt werden. Die Erkenntnisse der Untersuchung zeigen zudem, dass jene Lieferanten mehr Wert auf eine strategische Kunden-/ Lieferantenbeziehung legen, die auch eine hohe CSR-Performance aufweisen. Neben der Überprüfung und Sicherstellung von CSR rückt vermehrt die Information, Schulung und Weiterbildung zu CSR insbesondere von SMEs als Aufgabe für große Unternehmen in den Mittelpunkt. / Based on increased pressure on the part of different stakeholders, changed expectations on social issues as well as political frameworks, corporate social responsibility (CSR) gains more importance within the whole process of value add. Social responsibility extends the limits of the focal enterprise and includes the whole supply chain. The purchasing function is responsible for the important task (within the value add process) to source goods and services from third parties, the suppliers. Often production partners in emerging countries follow different legal and social standards. In order to compensate missing legal requirements and standardized norms, large MNE need to regularly supervise their supply base and secure CSR by themselves. This doctoral thesis aims to investigate the necessity of the integration of CSR as evaluation criterion in existing processes, with the result to be able to evaluate suitable suppliers for strategic relationships. Therefore based on expert interviews the method „CSR-IndexSA“ is being developed. This CSR-IndexSA allows the suppliers’ evaluation with a self assessment. The method is being proved for its reliability and is being adopted in a large scale empirical study involving numerous suppliers. The broad statistical analysis of existing evaluation criteria and processes with the measured suppliers’ CSR performance shows the need of the integration of CSR as independent criterion within the supplier evaluation process. The effects on existing processes are proven to be minor. Those results point to further relations between the “classical” criteria for evaluation and various CSR dimensions (e.g. environmental management) and give advice for an improved supplier evaluation. Furthermore CSR risk factors such as company size or region can be identified through the empirical survey. Long-term partnerships mean an increasingly important success factor in customer supplier relationships. The survey’s results show also that those suppliers who value a strategic relationship as important also have a high rating regarding CSR performance.

Background: Today most companies strive to offer logistics services in a highly competitive market. In the ecommerce sector a WMS is a crucial element since these systems can handle different amounts of volumes. Implementing such a system can contribute positively to the value creation. By focusing more on value co-creation rather than the value exchanged, companies can create more effective supply chains that benefit all actors involved. Purpose: The study’s purpose is conducted in partnership with Extenda Retail. The aim is to explore the implementation of a warehouse management system (WMS) from a value co-creation perspective. Based on the purpose two research questions have been formulated: What are the challenges associated with implementing a WMS? Which resources enrich value co-creation in the process of a WMS implementation according to a company's perspective? Method: The study is of a case study with Extenda Retail, and the method of data collection was semi-structured interviews, and document analysis. Results and Analysis: Value co-creation has always been a theory of discussion, with many actors and resources involved. The results emphasized knowledge, skills, customer involvement, user training and testing are factors that both contribute and challenge the value co-creation process. Conclusion: The findings show that applying a value co-creation lens has a significant role in effective warehouse management. Where resources from both company and customers are vital for the success of value co-creation. For example customer involvement, as in feedback, and request. Along with knowledge, and skills to manage a WMS, in the form of user training will ensure that the value of the product may be realized. The challenges identified for the study are as follows, balancing cost and quality, unmotivated customers, misinformation, changes and additions made to the scope. Future research: As our study is mainly focused from a company perspective, we suggest investigating the customer’s perspective and their experiences regarding resources integration, value co-creation and their interactions with their supplier.

Zementklinker ist der Hauptbestandteil von Zement und verbraucht zu dessen Herstellung signifikante Mengen von natürlichen Ressourcen und trägt gleichzeitig zu seiner sehr ungünstigen Treibhausgasbilanz bei. In dieser Arbeit wird gezeigt, dass Zementersatzstoffe mit spezifischen Eigenschaften aus Abfallstoffen wie Kieswaschschlämmen, Strassenwaschschlämmen und Gipskartonplatten ohne Leistungseinbußen auf Produktseite, bei geringeren Temperaturen und geringerer CO2 Emission hergestellt werden können. Entsprechend den angestrebten Eigenschaften solcher zum Teil anthropogener Zementbestandteile wurden lokal verfügbare geeignete Abfallstoffe ausgewählt und thermisch aktiviert. Eine industriell anwendbare Methode zur Aktivierung solcher Stoffe bei Temperaturen von 700 °C – 850 °C wurde entwickelt und patentiert. Es basiert auf einem neu entwickelten Trocknungsverfahren und der Kombination von zwei Produktionslinien, um durch die Verknüpfung der Gasströme beider Systeme eine energieeffiziente thermische Behandlung von Abfallstoffen zu ermöglichen sowie auf umweltfreundliche Weise einen Zementersatzstoff herzustellen.:Table of Contents List of Tables List of Figures List of Abbreviations Glossary Chapter 1: Introduction 1.1 Motivation 1.2 Research hypotheses and objectives 1.3 Research methodology 1.4 Thesis outline Chapter 2: State of the art in SCM production 2.1 Supplementary cementitious materials 2.2 Classification of SCMs 2.2.1 Classification according to origin 2.2.2 Classification according to reaction behaviour 2.3 Chemical composition of SCMs 2.4 Formation of hydraulic or pozzolanic minerals in thermal processes 2.4.1 Cement clinker 2.4.2 Burnt oil shale 2.4.3 Fly ash 2.4.4 Calcined clay 2.5 Performance of composite cements 2.6 Calcining technologies 2.6.1 Flash calciner 2.6.2 Rotary calciner 2.7 Comparison of process technologies 2.8 Summary of Chapter 2 Chapter 3: Alternative SCMs and a new method for activation 3.1 Introduction 3.2 Target of alternative SCM 3.3 Waste materials 3.3.1 Aggregate washing sludge 3.3.2 Road cleaning sludge 3.3.3 Deconstruction gypsum 3.4 Producing alternative SCMs 3.5 Thermal activation of alternative SCMs 3.6 Limitations in current calcining technology 3.6.1 Difficult emission control 3.6.1.1 Particulate emission 3.6.1.2 Gaseous emission 3.6.2 Challenging material preparation 3.6.3 Demand for noble fuels 3.6.4 Difficult colour control 3.6.5 Strict temperature control 3.6.6 CO2 footprint of calciners 3.7 Proposed new method of calcination 3.7.1 Feed material handling 3.7.2 Thermal heat-exchange system 3.7.3 Clay calciner design 3.7.4 Grinding 3.8 Summary Chapter 3 Chapter 4: Theoretical Considerations 4.1 Material considerations 4.1.1 Composition of alternative SCM 4.1.2 Anticipated products and characteristics 4.2 Process considerations 4.2.1 System capacity 4.2.2 Material characteristics 4.2.3 Material receiving, crushing and handling 4.2.4 Thermodynamic modelling 4.2.4.1 Mass balance 4.2.4.2 Drying and cooling heat balance 4.2.4.3 Calcination heat balance 4.2.4.4 Gas balance 4.2.4.5 Impact on clinker kiln line 4.2.4.6 Impact of calcite on the gas balance 4.2.5 Calciner design 4.2.6 Colour control 4.2.7 Emission prediction 4.2.7.1 Emission during drying 4.2.7.2 Emission during calcination 4.2.8 CO2 footprint of produced material 4.2.9 Grinding requirements 4.3 Summary of Chapter 4 Chapter 5: Experimental tests and proof of concept 5.1 Introduction 5.2 Sampling and characterization 5.2.1 Kaolinitic AWS from France 5.2.2 Non-kaolinitic AWS from Switzerland 5.2.3 Road cleaning sludges from Switzerland 5.2.4 Deconstruction gypsum from Switzerland 5.2.5 Sample preparation and shipping 5.3 Drying screw conveyor testing 5.4 Calcination testing 5.4.1 Mineralogy of activated products 5.4.1.1 Non-kaolinitic SCM 5.4.1.2 Kaolinitic AWS from France 5.4.2 Colour 5.5 Crushing tests 5.6 Grinding tests 5.7 Mortar compressive strength testing 5.8 Water demand testing 5.9 Summary of Chapter 5 Chapter 6: Experimental results 6.1 Characteristics of activated materials 6.2 Concrete performance and colour 6.2.1 Thermally activated kaolinitic AWS from France 6.2.2 Thermally activated non-kaolinitic alternative SCM from Switzerland 6.3 Equipment dimensioning 6.3.1 Process mass flow 6.3.2 Heat-exchanging screws and thermal oil system 6.3.3 Rotary calciner dimensioning 6.3.4 Ball mill dimensioning 6.4 CO2 reduction 6.5 Summary of Chapter 6 Chapter 7: Conclusion and outlook 7.1 Conclusions 7.2 Outlook.

[pt] A gestão da cadeia de suprimentos envolve múltiplos participantes, inúmeras incertezas e alta complexidade devido a um ambiente de negócios cada vez mais fragmentado e que envolve grandes volumes financeiros. A governança surge então como um caminho para melhorar o desenvolvimento de toda a cadeia de suprimentos, por meio de uma abordagem multidimensional e com foco no desempenho. No contexto da administração pública não é diferente, para as Forças Armadas a questão orçamentária é um desafio constante, nesse escopo, a Marinha do Brasil (MB), tem buscado austeridade nos gastos públicos, a despeito da necessidade de manter seus meios operativos em condição de plena eficiência, diante de um cenário de crescente participação em ações socias e operações que visam, por exemplo, a saúde de populações ribeirinhas e o combate a ilícitos. Dentro deste contexto, esta dissertação tem como objetivo melhorar o processo de compras da MB no escopo da cadeia logística de combustíveis, lubrificantes e graxas à luz dos preceitos e mecanismos de governança. Inicialmente, portanto, foi realizada uma revisão de escopo (RE) da literatura, tendo como resultado uma taxonomia e um framework que articulam os elementos basilares do conceito de governança na cadeia logística e as interações entre eles, corroborando a visão de interdependência entre os agentes da cadeia, seus processos e práticas. Os resultados da RE foram, então, aplicados em um estudo de caso na MB, através da análise inicial das publicações oficiais, da revisão do processo atual à luz dos conceitos que emergiram da RE e por meio de entrevistas com especialistas da MB. Como resultado, este estudo de caso proporcionou um processo de compras mais eficiente para a cadeia logística de combustíveis, lubrificantes e graxas da MB. / [en] Supply chain management involves multiple participants, numerous uncertainties and high complexity due to an increasingly fragmented business environment that involves large financial volumes. Governance thus emerges as a way to improve the development of the entire supply chain, through a multidimensional and performance-focused approach. In the context of public administration, it is no different, for the Armed Forces the budget issue is a constant challenge, in this scope, the Brazilian Navy (MB) has sought austerity in public spending, despite the need to keep its operational means in good condition. of full efficiency, in the face of a scenario of increasing participation in social actions and operations that aim, for example, at the health of riverside populations and the fight against illicit activities. Within this context, this dissertation aims to improve MB s purchasing process in the scope of the fuel, lubricant and grease logistics chain in the light of governance precepts and mechanisms. Initially, therefore, a scoping review (RE) of the literature was carried out, resulting in a taxonomy and a framework that articulate the basic elements of the concept of governance in the logistics chain and the interactions between them, corroborating the vision of interdependence between agents chain, its processes and practices. The results of the RE were then applied in a case study at MB, through the initial analysis of official publications, the review of the current process in the light of the concepts that emerged from the RE and, finally, through interviews with experts from the RE. MB, with the objective of proposing a new purchasing process for MB by enabling more efficient processes aimed at increasing the expected performance in the purchasing process.
