Decision-making For Emergency Material Dispatching Based On Multi-Mode Vehicles And Multiclass Materials

In the past few years, disasters broke out all over the world, which generate hugedamage to human beings. It has been a hot issue that how to dispatch emergency materialsto control the influence with a maximum extension and reduce the corresponding costafter disaster’s occurrence. The issue is to manage an effective and scientific method toschedule and distribute emergency materials quickly to the destroyed points with suchnatural constraints. Emergency material dispatching is the vital component of emergencylogistics research and should be its main research branch. More than that, with its focus onreducing the associated loss due to the disasters, research on emergency materialdispatching is definitely worthwhile.After research on the basic knowledge and domestic and foreign relevant research ofemergency logistics and emergency material dispatching, this thesis focuses on theproblem of emergency material dispatching decision-making. Based on the two conditionsof time restriction and non time restriction, this thesis proposes an emergency materialdispatching model based on multi-mode vehicles and multiclass materials with the goal ofminimizing the time accumulation of loss. And this model also considers the constraints oftransport capacity and load-upload capacity. A heuristic algorithm based on the combineddispatching principles is designed to solve this problem. Tow numerical example of theearthquake is used to illustrate the solution of the proposed model and application of thealgorithm. At the end of this thesis, it also carries out the sensitive analysis to illustrate theeffects caused by key parameters and get some valued results.
