Study of the Emergency Logistics Based on GERT

Abstract:

Disaster, emergency and epidemic diseases occur often bring huge losses, these losses in large part due to the loss of emergency logistics after disaster. So how to schedule schemes within shortest time in unpredictable situations, sent emergency resources to emergency locations within the shortest time is the key. According to the principle, GERT function, moment generating function, flow chart of theory and mason formula, then, combined with examples, construct an emergency distribution model. By calculating, distribution probability of success for each line and risk probability, the distribution of time and variance were achieved, then, analyze the defects in the model and areas in which need of improvement, and finally according to the defects put forward the improved solution.
