La chaîne d’approvisionnement des entreprises industrielles (Supply Chain (SC) en anglais) devient de plus en plus complexe de par le nombre d’interactions et interdépendances entre les différentes entités, acteurs, processus et ressources qui la composent. Ainsi, les entreprises s’intéressent de plus en plus à l’étude de leurs systèmes de performances pour aider à piloter et améliorer leurs processus. Les diverses approches existantes traitent essentiellement de la mesure et de l’évaluation de la performance des processus internes de l’entreprise. Notre approche, par la systémique, nous permet de prendre en compte toutes les parties prenantes intervenantes dans les chaines de valeurs globales, allant du besoin à la satisfaction du besoin. Dans le cas spécifique du secteur aéronautique (européen), le défi est d’autant plus important qu’il a été identifié que 70 à 80% de la valeur ajoutée (VA) est produite chez les fournisseurs de rang 1 et 2. C’est la raison pour laquelle nous nous intéressons dans cette thèse au périmètre de la sous-traitance de la production.Nos travaux de recherche sont organisés en trois parties :1) Une modélisation systémique au sein de la SC afin de considérer son système de performance dans sa globalité partant des objectives stratégiques (en termes d’indicateurs globaux) jusqu’à la re-conception des processus créateurs de valeurs internes. Cette modélisation permet d’identifier un sous-systèmeà étudier, les acteurs concernés et les attentes traduites par des indicateurs de performances qui sont mesurés à travers les processus internes. Nous identifions des indicateurs à prioriser et à améliorer en consensus avec les experts industriels.2) Un traitement de l’indicateur priorisé : « la Livraison à temps des fournisseurs (Supplier On Time Delivery) ». Dans un premier temps, nous analysons la mesure de cet indicateur, ses variables et ses paramètres qui l’impactent et nous approfondissons l’étude en se concentrant sur les dysfonctionnements (destructeurs de valeurs) qui empêchent d’atteindre les objectifs stratégiques fixés. Après cette phase d’analyse, nous proposons une simulation des impacts de dysfonctionnements sur l’indicateur et menons ensuite des analyses de sensibilité sur les variables identifiées afin de quantifier ces impacts et leur évolution.3) Une méthodologie d’établissement de plan d’actions d’amélioration à appliquer dans le périmètre étudié. Nous proposons une analyse qualitative sur l’implémentation des leviers et leur efficacité afin d’améliorer la performance.Des conclusions et limites de notre approche sont discutées et nous donnons des perspectives de recherche sur la re-conception et l’amélioration des performances de systèmes au sein de la chaîne d’approvisionnement. / The Supply Chain of industrial companies is becoming more complex due to the high number of interactions and interdependencies between different entities, actors, processes and resources belonging to the supply process. Thus, companies are increasingly interested in the study of their performance systems to help managing and improving their processes. The various existing approaches deal mainly with the measurement and the evaluation of the performance of internal business processes. Our work, based on the systemic approach, allows us to take into account all stakeholders involved in the global value chain, from the need to the fulfillment of it. In the specific case of the aeronautics (European), the challenge is even more important in as much as it was identified that 70 to 80% of value added (VA) occurred with the first and second-tier suppliers. This is why we focus our work within the scope of the outsourcing of aircraft production.Our research is organized in three parts:1) A systemic modeling within the SC is realized to consider the performance of the overall system, starting from the strategic objectives (in terms of global indicators) to the re-design of theinternal processes creating values. This model identifies asubsystem to be studied, stakeholders involved, and their expectations reflected by the performance indicators measured through internal processes. We identify indicators to be prioritized and improved by consensus with industrial experts.2) A treatment of the prioritized indicator "Supplier On Time Delivery" is proposed: first, we analyze the measurement of this indicator, its variables and parameters that impact it, and we go into the study in depth focusing on the dysfunctions (destroying values) that prevent achieving the strategic goals. After this phase of analysis, we propose a simulation of the dysfunctions’ impacts on the indicator and we then conduct sensitivity analysis of the identified variables of interest in order to quantify these impacts and their evolution.3) A methodology leading to an establishment of an improvement actions plan is presented in the perimeter studied. We provide a qualitative analysis on the implementation and effectiveness of the levers improving the performances.Conclusions and limitations of our approach are discussed and we provide research perspectives on the re-design and the improvement of the system’s performance within the supply chain.

M. Tech. (Department of Logistics Management, Faculty of Management Sciences), Vaal University of Technology. / In South Africa, the beverage industry is perceived to be a major contributor to the economy. Internal and external stakeholders in this industry are engaged in environmental collaboration with each other to achieve better environmental and supply chain performance. The aim of this study was to investigate the influence of green supply chain management practices on environmental performance and supply chain performance in the beverage industry of South Africa. It considers four of these practices, namely, internal environment management, investment recovery, eco-design and green purchasing. A quantitative approach was adopted, with the use of a survey questionnaire to collect information from 373 supply chain management professionals from beverage companies in South Africa. The study used a probability simple random sampling method. The data gathered was analysed using the Statistical Package for the Social Sciences (SPSS) version 25.0 and Analysis of a Moment Structures (AMOS) version 25.0. A Confirmatory Factor Analysis (CFA) was used to validate the measurement scales while Structural Equation Modelling (SEM) was applied to test the relations between constructs. The results revealed that internal environment management, investment recovery, eco-design and green purchasing positively and significantly influence environmental performance. Moreover, the results also revealed that environmental performance exerted a strong, significant and positive influence on supply chain performance. Recommendations and implications for further research were made based on these results. The study presents supply chain management professionals, internal and external stakeholders within the beverage industry with useful insights on key factors that ought to be addressed in order to improve their organisational strategies. Therefore, the study is essential to internal and external stakeholders in the beverage industry who wish to improve environmental and supply chain performance.

Ph. D. (Department of Business Administration, Faculty of Management Sciences), Vaal University of Technology. / The Small and Medium Enterprise (SME) sector has been receiving increased global attention from governments, researchers and management practitioners in both developed and developing nations as a vehicle for economic growth. The Zimbabwean SME sector has been on record as minimising the impact of the economic challenges on the economy thus proving the strategic role played by the SME sector in improving economic growth. Therefore, the Zimbabwean government has high hopes of resuscitating the economy through empowering the SME sector. However, the sector is inundated by challenges that have retarded its effectiveness in achieving the government’s expectations. Some key limitations and challenges include short life span of the SMEs, entrenchment of archaic business practices, lack of financial capitalisation and the failure to adopt a supply chain perspective of business. Although several solutions to the problem have been proposed and implemented, one solution that has not been fully tested relates to how people-centred knowledge management systems (KMSs) can be harnessed to improve the performance of SME supply chains in Zimbabwe. Therefore, the purpose of this study was to investigate the relationships between people-centred KMSs, knowledge sharing and supply chain performance (SCP) in the Zimbabwean SME sector. The study adopted a quantitative research method in which a survey design was implemented in collecting the data that were used to test the relationships on people-centred KMSs (i.e. communities of practice (CoPs), innovation management, organisational culture and social capital); knowledge sharing and SCP (i.e. time-related performance (TRP), cost-related performance (CRP), responsiveness-related performance (RRP) and operation quality-related performance (OQRP). A structured survey questionnaire was designed using measurement scales adapted from extant literature and it was administered to a sample of 580 SME owners, managers and employees who had some prior understanding of knowledge management, information technology and supply chain management. The collected data were analysed using the Statistical Packages for Social Sciences (SPSS) Version 25.0 and the Analysis of Moment Structures (AMOS) Version 25.0 statistical software. The data were analysed using both descriptive and inferential statistics. The statistical techniques used included measures of central tendency, cross-tabulations, factor analysis, multiple linear regression analysis, path analysis and structural equation modelling. The results of the study showed that SME employer qualifications (Kendall-tau = 0.88; p=.000), work experience (Kendall-tau = 0.86; p=.001) and nationality (Kendall-tau = 0.79; p=.010) as well as SME business sector (Kendall-tau = 0.89; p=.000) can be used to predict SME life span in the Zimbabwe SME sector. The results also showed significant relationships between three people-centred KMSs, namely, CoP (β=0.639, t=9.656, p=0.000), innovation management (β =-0.337, t=-8.578, p=0.000) and organisational culture (β=-0.261, t=-4.083, p=0.000) and knowledge sharing. The relationship between social capital and knowledge sharing was insignificant (β=-0.076, t=0.177, p=0.859). Significant relationships were also realised on knowledge sharing and three process-based SCP sub- factors, namely, TRP (β=0.231, t=4.717, p=0.000), CRP (β=-0.082, t=-2.015, p=0.044) and RRP (β=-0.177, t=-3.621, p=0.000). No relationship was found between knowledge sharing and OQRP (β=-0.076, t=0.049, p=0.254). Moreover, knowledge sharing was found to have a full mediation effect on people-centred KMSs and process-based SCP while no mediation effect was found with network-based SCP. The study makes substantial contributions to the existing body of knowledge. Theoretically, it provides in-depth insights of people-centred KMSs in SME SCP for developing countries such as Zimbabwe, which is an under researched area, thus expanding extant literature on the subject. From a knowledge management perspective, the study proposes the utilisation of SMEs’ socio-demographic factors to predict SMEs’ continued existence, thereby enabling financial institutions to offer financial assistance to such businesses with confidence. For governments in developing countries, the study suggests that specific attention should be directed to knowledge-based supply chains that adopt people-centred KMSs and process-based SCP to consider them as a possible alternative in addressing performance challenges in SME sectors.

M. Tech. (Department of Logistics Management, Faculty of Management Sciences), Vaal University of Technology. / The food retail industry is an important contributor to the economy. Buyers and suppliers in this industry work in collaboration with each other to achieve superior supply chain performance. To achieve this, they have to find ways and methods to improve it. The purpose of this study was to investigate the drivers of supply chain performance in the food retail industry in the Gauteng province. This study considers three of these drivers, namely buyer-supplier trust, buyer-supplier commitment and supply chain relationship longevity. A quantitative approach was adopted in which a survey questionnaire was used to collect data from 429 managers and staff members from food retailing firms in the Gauteng province. The study used a non-probability convenience sampling technique to select respondents. Data were analysed with the aid of two software packages, namely the Statistical Package for the Social Sciences (SPSS version 24.0) and the Analysis of Moment Structures (AMOS version 24.0). A confirmatory factor analysis was applied in examining and testing the relationships between observed constructs and their causal latent constructs while structural equation modelling was used to test the hypothesised relationships between constructs. The results of the research revealed that buyer-supplier trust, buyer-supplier commitment and supply chain relationship longevity positively and significantly influence supply chain performance. Buyer-supplier trust exerted a positive and significant influence on both buyersupplier commitment and relationship longevity. Also, the results showed that buyer-supplier commitment has a positive and significant influence on relationship longevity. The study concludes that to achieve greater supply chain performance, food retailers should expedite the levels of trust, commitment and length of relationships with their suppliers. The results of this study provide useful insights on how businesses in the food retail industry could benefit from trust, commitment and relationship longevity as well as on how to improve supply chain performance. The results of this study contribute to the existing body of knowledge by generating new information on buyer-supplier relationships. Therefore, the study is useful to buyers and suppliers in the food retail industry who wish to enhance supply chain performance and develop better relationships.

Analysis of the supply chain is necessary to improve performance. For this reason, supply chain management (SCM) has received a lot of attention recently and supply chain design (SCD) is a concept that forms an integral part of the adoption and implementation of SCM. Effective SCD contributes towards better supply chain integration (SCI) which, in turn, contributes towards improved supply chain performance. The focus of this study is on the analysis of SCD practices. Designing the supply chain structure is a complex and demanding undertaking that needs to be aligned with the needs of the supply chain’s end customers, because their needs ultimately have to be satisfied. This study proposes a conceptual framework that has been developed from literature to assist organisations in the analysis of their SCD practices, with the aim of improving supply chain performance. The conceptual framework was exploratively tested by means of empirical research to determine whether it can be used as an assessment tool to assess the SCD practices of organisations. The study concluded that the conceptual framework that was developed in this study can be used as an assessment tool with which organisations can analyse their SCD practices. / Business Management / D.

As this study focus on a private brand project of the company, it has applied some knowledge sharing methodologies such as e-commerce and online communities, it would be worth to explore and implications of supply chain management. This study examines the impact of supply chain integration on supply chain performance. In the literature review, the facets of supply chain integration are divided into three aspects: suppliers, customers, and internal integration combined with the supply chain management mentioned in the literature and linked to the performance evaluation indicators in the SCOR model. The above review brings out the supply chain integration method which will be discussed in this study. This study uses a qualitative case interview method to investigate the embedded brand company's own brand product line, and explores the positive effect of supply chain integration on the supply chain performance in project management scope. This study finds that in the project management, in addition to the supply chain integration mentioned in the research framework, the supply chain integration in practice guided by each functional unit has a positive impact on performance. In the conclusion, the study focused on three different supply chain integration facets, collated the direct and indirect impacts of SCOR performance indicators in the supply chain integration method, and providing the corresponding suggestion in the conclusions.

Le supply chain management fait l'objet d'une attention particulière de la part des entreprises et des chercheurs notamment en sciences de gestion. Il s'articule autour de la mutualisation de ressources et des compétences de chaque membre de la supply chain et la synergie qui subsiste entre eux afin de créer collectivement une valeur supérieure à la somme des valeurs créées séparément par chacun. Cette alliance, qui nécessite la coopération collective dans la création et le partage équitable de la valeur, est caractérisée par des comportements opportunistes qui entraînent des défaillances comme l'effet Bullwhip. Ainsi, notre objectif est d'analyser ces comportements afin de comprendre leur dynamique au sein de la supply chain. A cet égard, nous nous appuyons sur la perspective des dilemmes sociaux pour proposer deux mécanismes : un mécanisme motivationnel (partage de l'identité de la supply chain) et un mécanisme structurel (investissement dans les ressources relationnelles) pour à la fois réduire et décourager l'opportunisme. Afin d'appuyer notre raisonnement, ces mécanismes sont articulés pour créer un capital social qui, en facilitant le supply chain management, permet d'améliorer la performance de la supply chain. Cela a donné lieu à la conception d'un modèle intégrateur de la dynamique sociale de la supply chain. Celui-ci a été validé auprès d'un échantillon de 130 répondants (Responsables supply chain, directeurs logistiques, etc.). Les données collectées ont été analysées tout d'abord par une analyse univariée, suivie d'une analyse en composantes principales afin d'épurer nos échelle de mesure. En second lieu, nous avons fait appel aux modèles d'équations structurelles PLS-PM (régressions aux moindres carrées partiels), pour estimer d'une part, la validité convergente ainsi que la validité discriminante des échelles de mesures, et d'autre part, valider nos hypothèses de recherche relatives aux antécédents et aux conséquences du capital social de la supply chain. Les résultats d'analyse nous ont permis de valider toutes les hypothèses selon lesquelles les deux mécanismes de résolution du dilemme social permettent de développer un capital social au sein de la supply chain qui, en agissant comme un lubrificateur des relations inter-organisationnelle, permet d'améliorer la performance de la supply chain. / Supply chain management is subject of particular interest to professionals and researchers especially in management science. It revolves around the sharing of resources and expertise between supply chain members, and the synergy that exists between them to collectively create value that is more than the sum of the values created separately by each member. This alliance, which requires collective cooperation in the creation and the equitable sharing of the value, is characterized by opportunistic behaviors that lead to failure, as illustrated by the Bullwhip effect. Thus, our objective is to analyze these behaviors in an attempt to understand their dynamics within the supply chain. In this regard, we rely on the perspective of social dilemmas to propose two mechanisms: a motivational mechanism (sharing the identity of the supply chain) and a structural mechanism (investment in relational resources) to discourage and reduce opportunism. To support our reasoning, these mechanisms are articulated to create social capital, facilitating supply chain management, in turn improving supply chain performance. This leads to the design of an integrative model of supply chain social dynamics. This was validated with a sample of 130 respondents (supply chain heads, logistics managers, etc.). The collected data were analyzed first by univariate analysis followed by principal component analysis to refine our scale. Second, we used PLS-PM (partial least squares regression) structural equation models to estimate, on one hand, the convergent and the discriminant validity of the measurement scales validity, and on the other hand, validate our research hypotheses on the antecedents and the consequences of social capital in the supply chain. The results of these analyses have allowed us to validate all the assumptions that the two mechanisms for resolving social dilemma help develop social capital within the supply chain, and act to lubricate inter-organizational relations, allowing improved supply chain performance.

Dans le contexte économique actuel, les entreprises cherchent à développer de nouvelles stratégies de distribution pour leurs performances logistique. Dans cette quête de performances, les entreprises doivent adapter les stratégies de distribution misent en place avec les typologies de leurs produits. Plusieurs stratégies de distribution existent dans la chaîne logistique de grande distribution. Ces stratégies sont choisies sur la base des caractéristiques des produits, et /ou l'impact sur les performances logistiques. Dans cette thèse, nous étudions l'impact de trois stratégies de distribution, à savoir: stockage traditionnel, cross-docking pick by line et le cross-docking pick by store, sur trois performances de la logistiques, à savoir: le niveau de service, les coûts et le bullwhip effect. En outre, nous analysons l'impact des caractéristiques des produits sur les performances des stratégies de distribution et enfin proposer un cadre pour le choix de la stratégie la plus adaptée pour chaque produit. La chaîne logistique étudiée est composée de trois échelons: Centre de distribution du fournisseur, Centre de distribution du distributeur et les magasins. Basé sur un cas réel, nous effectuons une modélisation des processus, qui nous permet de développer un modèle déterministe de coût Macro et un modèle de simulation. Le modèle de coût macro permet d'évaluer l'impact des stratégies de distribution sur des coûts de la chaîne logistique. Après l'analyse macro des coûts, nous développons un modèle de simulation où nous intégrons les données relatives aux produits (la demande, le volume, etc.). Ce modèle permet une simulation dynamique du système la stratégie la plus adaptée pour chaque produit en fonction de ses caractéristiques et de l'impact sur les performances. A la fin de cette recherche, nous présentons une matrice de choix pour la segmentation des produits et choix de la stratégie de distribution. / Nowadays companies must look to develop new distribution strategies in order to achieve the required performance from their supply chain. In this quest, companies wonder about the consistency of their distribution strategies with the products they are selling. Several types of distribution strategies exist in the retail supply chain. These strategies are chosen based on the products characteristics, and/or the impact on the supply chain performances. In this research, we study the impact of three distribution strategies, namely: traditional warehousing, cross-docking pick by line and cross-docking pick by store, on three supply chain performances, namely: service level, cost and bullwhip effect. In addition, we analyse the impact of the products characteristics on the performances of the distribution strategies and propose a framework for choosing the right strategy for each product. The supply chain studied is composed of three echelons: Supplier Distribution Centre, Retailer Distribution Centre and Stores. Based a real business case, we perform a process modelling, that allows us to develop a deterministic Macro cost model and a simulation model. The macro cost model allows to evaluate the impact of the distribution strategies on the supply chain cost performance. After the macro cost analysis, we develop a simulation model where we integrate the data related to the products (demand, volume, ordering quantities etc.) in the model. This model allows a more dynamic simulation of the system in a large time period and determines the right strategy to select for each product depending on its characteristics and the impact on the performances. At the end of this research, we present a framework for product segmentation and distribution strategy selection.
