Relief distribution logistics play a critical role in disaster response, particularly in geographically diverse and disaster-prone regions like Oman. However, the complexity of these logistics systems often hinders the timely and effective delivery of aid. This study aims to identify the key variables influencing modern relief distribution logistics systems during disaster response in Oman through a hybrid content review. Using qualitative content analysis with ATLAS.ti software, we systematically analyze selected top-tier research papers to uncover core factors, including operational challenges, technological advancements, collaboration frameworks, and socio-environmental considerations. By synthesizing findings from diverse sources, the study provides a comprehensive framework of variables critical to optimizing disaster logistics systems. This research not only enhances understanding of the logistical challenges in Oman but also provides actionable insights for policymakers and humanitarian organizations to improve disaster response efficiency. The results contribute to the broader field of disaster management and establish a basis for future empirical studies on logistics systems in developing countries. The findings of the analysis highlights that relief efficiency is heavily influenced by challenges such as infrastructure damage and distribution bottlenecks. Effective information sharing and stakeholder engagement are critical to mitigating bottlenecks and ensuring time-critical deliveries. Technological tools like digital twin simulation play a key role in visualizing supply chain constraints and optimizing logistics. Addressing these factors collectively can significantly reduce lead times and enhance the overall effectiveness of relief distribution efforts.
