Disaster logistics, or humanitarian supply chain management, has attracted research attention in recent years. This paper develops an estimation model to estimate the types and quantities of emergency goods necessary to support earthquake relief operations. It is crucial that the buffer stock for earthquake relief be well defined and ready to deliver to disaster areas when an earthquake occurs. This paper therefore serves as a guide to disaster logistics, especially how to estimate the emergency goods needed for earthquake relief operations. It not only reviews the literature to describe current practices and research trends in disaster logistics but also provides a model framework to estimate the emergency goods necessary in this regard.
