Abstract

In view of emergency supply shortage at beginning of disasters, different disaster sites and constrain of time windows, studies were carried out on supply delivery and vehicle path planning. Then, a path scheme generation model of emergency material delivery was constructed based on constraint of comprehensive time windows, aiming at maximizing time and demand satisfaction while taking principle of fairness during rescue taken into consideration. Secondly, demand satisfaction was calculated by using S. Adams' fair theory, and the model was solved with genetic algorithm. Then, based on real cases, results of different fair distribution methods were compared and analyzed to choose the best allocation plan and identify critical segments along delivery paths to ensure smooth transportation. The results show that this model can not only solve problems of emergency materials distribution and vehicle route generation under shortage of materials, but also effectively identify key transportation roads. © 2019 China Safety Science Journal
