In response to the challenges posed by the Qatar blockade, this proposal aims to address the critical gaps in retail supply chain resilience, particularly focusing on supplier diversification strategies amidst various supply chain disruptions. The blockade significantly impeded the ability of prominent retail establishments to meet customer demands due to disruptions in conventional import channels, underscoring the vulnerability of relying on a single supplier. The research will implement a mixed-integer linear programming (MILP) approach to minimize supplier dependencies while maximizing market coverage, thus mitigating buyer risk and enhancing operational resilience. By employing a centralized aggregate sourcing strategy with fewer suppliers, the methodology seeks to improve control over purchasing processes, maintain stringent quality standards, and achieve cost efficiencies through economies of scale. Anticipated outcomes include enhanced operational efficiency, simplified decision-making processes, and a more resilient supply chain capable of withstanding future disruptions, thereby contributing to the broader discourse on supply chain resilience in volatile environments.
