Differences between commercial SCs and Humanitarian SCs are: the commercial one is set up and remains unfixed for long time, whereas the latter is a temporary structure that is set up following incidents. The metrics in humanitarian SC may not be computed as cost. Uncertainty is inherent in design of SC.   In order to keep a record of these events, the Centre for Research  on the Epidemology of Disasters (CRED) has developed the  International Disaster Database (EM-DAT) containing information  on the occurrence and impact of more than 18,000 disasters since  1900  Some useful conjunctive points:  The primary difference between commercial and humanitarian supply chains lie in their goal and shape of the demand.
