Data-Research on emergency material demand based on urgency and satisfaction under public health emergencies

In recent years, the frequent occurrence of public health emergencies has had a significant impact on people's life. The study of emergency logistics has also attracted scholars’ attention. Therefore, matching emergency materials’ supply and demand quickly, which meets urgency and satisfaction, is the purpose of this paper. This paper used <strong>the Metabolism Grey Model (1,1) </strong>(GM (1,1)) and the material demand prediction model to predict the number of infections and material demand. Besides, we established <strong>a double objective optimization model</strong> by constructing<strong> a profit and loss matrix and a comprehensive utility perception matrix. </strong>The results show that the method is helpful in matching the optimal supply and demand decision quickly on the basis of meeting urgency and satisfaction. The method is helpful in improving the fairness of emergency material distribution, which could better protect people's livelihoods. <br> <br> The data comes from the Hebei Provincial Health Commission (2022.04.05–04.11, http://wsjkw.hebei.gov.cn/ ). <br> <br> The voting weight of the 5 demanders on the index attribute comes from a questionnaire. <br> The voting weight of the 5 suppliers on the index attribute comes from a questionnaire. <br> <br> The evaluation value of the index attribute by suppliers comes from a questionnaire. <br> <br> The evaluation value of the index attribute by demanders comes from a questionnaire. <br>
