Research on emergency materials grading based on entropy weight and grey associated analysis

Author(s): Cheng Hu-Biao, Jiang Da-Li

Emergency materials are the material basis to deal with unexpected events. The emergency materials grading is one of the key issues in optimizing inventory management and improving operational efficiency in emergency system. This paper builds a hierarchical evaluation system through analyzing the influence factors of the grading of emergency materials, then designs the grey associated analysis model combing entropy weight, obtaining the comprehensive priority order and grading of emergency materials. The number experiment analysis proves that this method is effective and provides the mathematics basis for optimizing the decision of emergency materials reserve
