Then, based on an updating literature review and evaluation of ongoing studies, concludes with main findings and gaps, and suggestions about future research directions. The article serves as an update on previous literature reviews in humanitarian logistics. Our analysis shows that there are still considerable gaps in practical applications; in the incorporation of vulnerability and safety aspects of relief item distribution such as robbery and despoliation; in the effects of dynamic road availability updates; in multi- period, multi-level, and multi-objective relief item distribution; in the considerations of social costs; in the incorporation of human behavior; and in the needs of cross-services. Keywords: Relief item distribution management; Disaster management; Humanitarian supply chain; Disaster-relief supply chain; Humanitarian logistics; Uncertainty in disaster management.  Corresponding Author.
