Item Restricted EVALUATING THE IMPACT OF GREEN LOGISTICS PRACTICES ON SUPPLY CHAIN PERFORMANCE: A CASE STUDY OF IKEA(University of Sussex, 2024-09-18) Alshahrani, Mamdouh Mohammed; Kondic, AdelaThis dissertation explores the influence of green logistics practices on IKEA’s supply chain performance with a focus on operational efficiency and economic outcomes. Quantitative research design was employeed and data was gathered through a structured questionnaire distributed to IKEA employees engaged in logistics and supply chain roles. The findings reveal a high level of awareness and adoption of green logistics practices at IKEA. However, the perceived impact on operational efficiency and economic performance is moderate. The study identifies key areas for enhancement particularly in the cost-effectiveness and strategic integration of these practices with IKEA's broader sustainability objectives. Overall, IKEA demonstrates considerable progress in implementing green logistics but the research underscores the need for ongoing refinement to maximize their benefits.15 0Item Restricted IMPACT DE LA FABRICATION ADDITIVE SUR LA PERFORMANCE DE LA SUPPLY CHAIN(Université de Bordeaux, 2023-11-29) Noorwali, Albraa; Ducq, YvesAdditive Manufacturing (AM), often referred to as 3D printing, is a technology that allows for the direct creation of 3D products from digital models, offering industries new possibilities for design, customization, and rapid prototyping. Its impact spans industries such as aerospace, healthcare, and automotive, promising cost-effective production and innovative solutions. However, the quality of AM-produced products depends on the post-processing operation, and some non-quality issues are often encountered. Despite the extensive literature comparing AM to conventional manufacturing (CM), there is still a need for empirical evidence and comprehensive cost analyses to guide companies in adopting AM, especially by considering the non-quality issues. This thesis addresses this gap by (1) empirically investigating the impacts of AM across all supply chain processes by using collected data from a sample of 51 companies, (2) evaluating, by means of a simulation study and data from an oil and gas company, the practicality and cost-effectiveness of shifting from CM to in-house AM production while considering investment costs and different quality levels, and (3) exploring the advantages of integrating AM within a dual sourcing framework to assess cost implications and resilience benefits. The empirical investigation shows two major benefits of AM, namely: the ability to produce complex parts in low volumes and good design and the prototyping capability. Moreover, the simulation study provides evidence on the limits of AM when there is a low-quality level generated by postprocessing. The thesis enables as well to show the benefits of using AM within a dual sourcing context.21 0Item Restricted Exploring Challenges and Solutions in Supply Chain Management of Construction Companies(University of Warwick, 2023-12-06) Alqarni, Ahmed; Adeyemi, OlabisiThis project examined the challenges and solutions in the supply chains of construction companies in the United Kingdom. With events such as the COVID-19 pandemic, many construction companies faced numerous operating challenges that affected their efficiency. Some significant issues included supply chain disruptions because of the border closures characterised by critical supply chain disruptions. In an accurately functioning design construction system, providing services must be characterised by accessibility, coordination, efficiency, comprehensiveness, quality, customer-centeredness, and accountability. Thus, this project sought to identify some of the challenges that trigger the inefficiency of construction company supply chains and how to solve them. The objectives included explaining the key construction company supply chain processes, identifying issues and challenges in the construction company supply chain processes, investigating how to optimise the supply chain, and identifying critical solutions for improving construction company supply chain performance. A mixed study design was used using an exploratory approach. Quantitative and qualitative data were used, where the analysis focused on twenty previous literatures, including expert opinion, five case studies, and five construction company reports. The quantitative data was used in analysing and explaining the qualitative data in succession. Purposive non-probability sampling was used to select the 30 sources. Thematic analysis was used to organise the articles in a way that helped identify key patterns aligning with the sample narrative. This study focused on five UK construction companies: Skanska UK, Mace, ISG, Willmott Dixon Interiors Limited, and Laing O'Rourke. An analysis of five case studies and five company reports helped identify some of the construction supply chain challenges. Five major themes were identified after a thematic analysis of twenty sources: supply chain complexity, internal HR supply chain management, sustainability, supply chain interruption, and external economic outlook. These themes were classified as the key construction supply chain challenges. For sustainability, the solutions included supply chain collaboration and integrated supply chain competing value, for external economic outlook solutions included supply chain integration and resilience and for supply chain interruption the solutions were supply chain resilience and integrated supply chain competing. For complexity, the solutions were increasing visibility and eliminating redundancies, while for internal HR supply chain management, the solutions were HR collaboration and increased supply chain networks. With these findings, it is accurate to argue that construction supply chains are complex and need to be managed from points of view that support the alignment of key operations.29 0
