Abstract

Locality unexpected natural disasters or sudden public health incidents in recent years have occurred to the human cause significant and even devastating blow to constitute a major threat to human survival and development. In this context, in order to prevent emergencies under the expansion of the disaster, to reduce the affected area and the loss of life and property, and to restore the production and living order, resulting in a huge demand for temporary emergency logistics. The implementation of the emergency logistics, protection of emergency supplies core areas, emergency supplies is the premise and foundation of all other emergency work, the ultimate purpose of the other work is sent emergency supplies to the victims. Inventory levels of emergency supplies directly related to the ability to effectively curb the further disasters occur. Therefore, to study and explore effective countermeasures, emergency supplies inventory management and logistics system to improve emergency response capacity, to improve the level of emergency logistics, and has a good theoretical significance and value in use. The article first reviews the status of emergency logistics and emergency supplies inventory management, and introduces the concept of emergency logistics and emergency supplies, emergency supplies classification, characteristics, pointed out that the knowledge of inventory management of emergency supplies management processes and requirements, as well as emergency supplies. Followed by a brief classification of emergency supplies inventory and inventory control model, emergency supplies inventory management is divided into two sub-problems: emergency supplies inventory classification and reserves determined on this basis. Then use the Fuzzy Analytic Hierarchy Process Category: inventory of emergency supplies to build emergency supplies evaluation index system, using AHP to determine the weight of each index membership degree matrix determined by questionnaire, fuzzy evaluation method to determine a material degree of urgency. Determined on the basis of materials urgency of considering the probability distribution of the material needs of different disasters intensity, due to shortage of material reserves, excess and material reserves disaster losses, and then use the information entropy principle to build reserves to determine the model of emergency supplies to determine the amount of its reserves, and strive to make emergency supplies inventory can meet the disaster needs, but also make the most efficient use of special funds. Finally, a numerical example of national regulations must reserve emergency supplies of tents. Based on the establishment of Fuzzy AHP model to determine the tents should be for the emergency reserve supplies, then the the central relief reserve warehouse Hefei warehouse as an example, by the tent needs different disasters of the past 20 years, the use of information entropy model to determine the reserve point The appropriate amount of the reserve, the number of calculated results with the actual storage coincide.
