The Research On Emergency Supplies Transportation Scheduling In The Emergency Logistics

Despite the rapid advancement in technology in today's world, the forecasting of natural disasters has been developed to a considerable level, but local, regional, regional and even national scope of natural disasters, public health emergencies occur from time to time, to causing significant human and even a devastating blow to the survival of human and social development constitutes a major threat. Sudden major natural disasters and public health caused by such giants of casualties and property losses, will inevitably require a large amount of emergency supplies to address the victim assistance, health and epidemic prevention, the deceased was buried, the post-disaster reconstruction, the restoration of production and so on, unless the affected area, personnel, property damage will be expanded, disaster may evolve into a disaster.The need for disaster relief emergency supplies a large number of wounded, resettlement of the victims, people in disaster relief when faced with an important issue is how to effectively use the limited means of transport to the disaster-stricken region a large number of timely transport relief goods to the greatest degree of disaster mitigation, reduce the loss of the victims. Therefore, when the people in the face of disaster relief as an important issue is how quickly and efficiently to the affected areas from the surrounding regional transport a large number of disaster relief supplies, such as medicines, medical equipment, life-saving equipment, food, clothing, tents and so on.In this paper, emergency supplies transportation scheduling features are analyzed, emergency supplies the framework of transport scheduling system are set up, the basic content of scheduling transportation introduced and analyzed transport emergency supplies in the scheduling system to address several key issues.Finally, a reasonable assumption based on a random time transportation scheduling model transport emergency supplies, through the rational organization of the transport vehicle tasks, so that the affected area as a result of unmet demand for transportation of materials caused by the smallest loss. In the model, consider the constraint conditions are:the number of restricted materials, vehicle flow and vehicle load balance constraint bound. Designed to transport emergency supplies for solving the genetic algorithm scheduling model, from the encoding method, fitness function, genetic operators and other aspects of the traditional genetic algorithm is improved. An example, given the system output data, an analysis of punishment coefficient model algorithm control parameters and the experimental results proved the validity of models and algorithm.The research above can provide scientific foundation for the government getting a reasonable vehicle schedule when disaster happens.
