Therefore, rational allocation of human resources can minimize the total loss of the relief, then make the process of disaster relief efficient and feasible. Through analysis of the three actual situations, transfer of relief materials, on condition that human resources are in a limited circumstance, we can establish a model relationship between the total losses to plete this task and the allocation of human resources with the tools of calculus. That’s to say the plex issue, the allocation of huma
