基于模糊聚类的应急物资分类储备研究

Research on Classified Reserve of Emergency Materials Based on Fuzzy Clustering Analysis

对品种繁多的应急物资进行分类是科学储备应急物资的前提和基础。以应急物资的自然属性和社会属性以及突发事件的应急需求为基础,从应急物资的有效使用期限、用途、生产周期、价格、市场流通量、社会集中拥有量、突发事件的预计需求量和需求层次8个方面建立应急物资的分类指标体系;采用模糊聚类的方法对应急物资进行分类,并用经验正交函数方法确定应急物资的最佳分类数量;最后探讨了每一类应急物资的储备模式,为应急物资的科学储备提供借鉴。

Classification of a wide range of emergency materials is the foundation of emergency material reserve. Based on the natural and social attributes of emergency materials and need in emergency response, the classification index system of emergency materials is worked out in eight aspects as effective life, function, production cycle, price, market circulation, concentrated possessive quantity of community, expected demand and expected and demand level of emergency materials. The emergency materials are classified by the method of fuzzy clustering analysis and the optimal classification number is determined by the method of empirical orthogonal function. The reserve pattern of each type of emergency materials is analyzed, which is helpful to the scientific reserve of emergency materials.
