The Study on Multi-base Direct Joint Distribution of Emergency Relief Materials in Large-scale Emergencies

Yuanwen Chen

Abstract


After the occurrence of large-scale emergencies, reasonable distribution and efficient delivery of emergency relief supplies determines the success of a rescue operation, which is of vital importance to people’s life and their property safety. Based on the problem of direct distribution of various relief materials to several demand points in the affected areas, by using multiple means of transportation delivering materials from the supply points, considering road condition, numbers, volume and load capacity of carriers, this article sets up a mathematical model which aims at spending the shortest time and using the least number of carriers. This article solves the model by adopting hybrid programming of MATLAB and GAMS. The test proves that this model is correct, the solution speed is fast and the result is reliable.
