Abstract：Earthquakes are a special type of disaster that has been proved difficult to predict exactly while occur with abruptness, and these two attributes make the post-disaster mobilization work become a vital procedure. According to the main distribution of earthquake faults in our country, a facility location-allocation stochastic mixed integer model, which considered the uncertain demands of disaster areas and the special environment in disaster relief, was proposed to determine the facility locations of distribution centers, the initial inventory levels at these established facilities and the overall transportation plans from facilities to disaster areas. Furthermore, a heuristic algorithm based on Lagrangian relaxation idea was also developed according to the special structure of the proposed model. The efficiency of the proposed model and algorithm was validated by a data case that constructed from the simulative situation of the great Wenchuan earthquake.
