Item Restricted A Comparative Analysis of Circular Economy Practices in Saudi Arabia with Leading Countries(Cranfield University, 2024-09) Alsaud, Khalid; Assad, FadiAs a result of the increase in urbanisation and resource consumption, the need for sustainable economic models has become noticeable. The linear economy model, established globally, consumes non-renewable resources, exceeding the earth's capacity which exhibits significant shortcomings that limit sustainability, requiring a shift towards CE as a sustainable conception. Saudi Arabia, one of the largest global economies, is striving to adopt this transformation due to significant environmental and economic challenges. Saudi Arabia has no specific strategy for the circular economy. This hinders the ability to find solutions of the challenges waste management and excessive consumption issues. The country is lacking a comprehensive framework that compares its policies with leading countries. A framework was developed to analyse and compare circular economy initiatives, strategies and policies between Saudi Arabia and China, Japan, and Europe. Collected data were examined and policies and strategies were analysed using thematic analysis. This approach allows for the identification of commonalities and differences between the countries. The study highlighted differences in policies and practices, identifying best practices that Saudi Arabia could adopt to enhance the sustainability. The findings emphasise the need of adopting global best practices and developing local strategies to KSA. Policymakers and researchers in Saudi Arabia can leverage these results to contribute to more effective shift to the CE. This work can by developed by implementing this study on quantitative study approach where indicators and metrics are compared, which leads to greater impact.19 0Item Restricted An Integrated Methodology for Non-Destructive Reliability Assessment of Remanufactured Components(The University of New South Wales, 2024-10) Aloqaibi, Yasser Owaitiq; Kara, Sami; Wang, ChunReliability assessment is a quality measure that has been used in industry for a long time. It is used as a quantified indicator to determine the probability of a component performing its function properly for a given period. Assessing the reliability of a remanufactured component becomes a key factor in determining the success of remanufacturing industry. The aim of this research was to provide a data-driven and integrated methodology to evaluate the reliability of a remanufactured component in a non-destructive way. To achieve this research objective, a methodology was presented for an accurate and empirical reliability assessment of remanufactured components. The proposed methodology was constructed using available historical data collected during the initial life cycle of a given component. From these collected data sets, a degradation model of the component was built to represent the inevitable deterioration of the component’s performance. One of the significant modules of the methodology was estimating the outcomes of a proposed remanufacturing process. A mathematical and digital simulation approach provided an integrated method to estimate the outcomes of the proposed remanufacturing process. To develop the robustness of the proposed methodology, a statistical model development scheme was implemented to provide a mean value and predicted interval analysis. This model provided a distribution-based estimation for the component’s failure characteristics. Ultimately, the reliability assessment of remanufactured components can be calculated properly using empirical and actual parameters. This methodology was validated by conducting two case studies with different remanufacturing processes. The conclusion of this study represented a promising approach to predicting the reliability of remanufactured components in a non-destructive way. This methodology could be also capable of incorporating other remanufacturing processes and supporting the decision-making process. Furthermore, it was able to facilitate the technical decisions of conducting a specific process parameter to improve the result of the remanufacturing process. The advantage of remanufactured components was measured by assessing their reliability.24 0Item Restricted A Truly Circular Supply Chain Project (Optimizing The Use Of Cardboard Material By Simulating The Warehouse Operations)(Cardiff University, 2023-12-01) Alasmari, Loloah; Packianather, Michael; Tuthill, PeterThe imperative of environmental responsibility extends across all sectors, prompting companies to initiate projects aimed at minimising their environmental impact. This project's core objective is a comprehensive assessment of DSV's company warehouse, with the aim of transforming it into a circular supply chain aligning it with sustainable and efficient practices. The main question is it applicable to simulate such an operation and find a solution to eliminate the waste of material in the warehouse? And which factors are more important to control while applying CE concept. To achieve this transformation, this thesis incorporates lean manufacturing principles. The VSM concept is applied, and the 6R concept is considered while developing the model. Also, proposed solutions for closing the supply chain loop are offered to ensure the robustness of the results. The simulation model is constructed using WITNESS software, validated for accuracy, and subsequently subjected to twelve distinct scenarios. These scenarios simulate various situations the warehouse may encounter, allowing an in-depth examination of the model's flexibility. Six scenarios pertain to off-peak seasons, characterised by an average of 7,000 packages per day, while the remaining six scenarios represent peak seasons, with an average of 10,000 packages per day. Each scenario is run independently, with the results meticulously documented and analysed. A comparative evaluation is conducted to assess the effectiveness of each alternative. The key parameters used for performance comparison are the level of blockage within the system, categorised as low, moderate, or high, and the utilisation rate of the processes represented as a percentage. These factors serve as pivotal indicators to assess the efficiency and effectiveness of the model. It is observed that the models not considering the recycling process exhibit greater flexibility than their counterparts. This result is important due to the significant difference they can make to the warehouse operation by increasing the efficiency of the operation, saving cost, and aligning with contributing to making their operations greener. Furthermore, suggestions for future improvements are presented in this thesis, ensuring that any on-site actions are grounded in a simulation that faithfully reflects reality.24 0Item Restricted Applied Business Project(ABP)(Saudi Digital Library, 2023-12-01) Mrair, Yahya Musawi; Osti, LindaApplied Business Project (ABP) Business Planning Circular Economy International Business Leadership in rapidly changing environments.33 0
