Emergency Materials Dispatch Based On Road Restorability

In recent years, with the focus on emergency, a great many of research interests have been shown on Emergency Material Dispatch (including transportation optimization scheduling, routing selection, emergency center plan, a save point selection and so on), which is the key to effective completion of emergency rescue work. However, during the operation of the Emergency Material Dispatch, there is the phenomenon of incompatible materials distribution, disaster point demand satisfaction rate imbalances and emergency material waste. Therefore, we should further study the key factors in Emergency Material Dispatch in order to realize dynamic scheduling for emergency material and further improve the level of emergency material dispatch.After analyzing the relevant examples of emergency material dispatch, we find out the inappropriate problems and propose some improved scheme from both theories and scheduling model. Firstly, by analyzing low satisfaction of emergency material dispatch caused by information asymmetry and combining with emergency material dispatch features and information tools, we plan the process of emergency material dispatch from material requirements identification, material collection, material scheduling and materials recovery. Secondly, road restorability has an important impact on the dispatch of relief materials, so we calculate the urgency of the disaster point by it. Thirdly, emergency material dispatch is usually lagging behind. We divide into different stages by the change of state and change the urgency of the disaster point in accordance with the properties of real-time. At last, we design a dynamic scheduling model of emergency material, which maximize the material requirement satisfaction of the disaster point as the objective function.In the end, in order to verify the effectiveness of the model, we carry out a large number of simulation experiments. Through the comparative analysis, we can find that the requirement satisfaction of the disaster point based on the traffic capacity is higher than which doesn't contain this factors. This provides a new solution for study of the emergency material dispatch which is worth using for reference. At the same time the thesis predicts the emergency material dispatch and gives some directions of future research.
