Emergency Logistics and Distribution Modeling and Methods

With the frequent occurrence of all kinds of emergencies, the importance of emergency logistics distribution has become increasingly prominent. This thesis focuses on the field of emergency logistics distribution, aiming to analyze distribution models and methods to improve the efficiency and effectiveness of emergency material distribution. First, the characteristics and needs of emergency logistics distribution are analyzed in depth, including time urgency, uncertainty and multi-targeting. Then, for the two key aspects of cost and benefit, cost components such as transportation cost, warehousing cost, labor cost, loss and damage cost, and benefit indicators such as rescue effect, economic benefit and social benefit are elaborated in detail. It also explains that factors such as material response time, transportation speed, completion rate and accuracy should be considered. Meanwhile, in the cost and benefit analysis, methods such as cost-benefit ratio (CBA), cost-efficiency analysis (CEA) and benefit assessment are illustrated, and finally recommendations covering various aspects are put forward to improve the emergency logistics and distribution system.
