Mixed Distribution of Relief Materials with the Consideration of Demand Matching Degree

摘要

Timely and effective distribution of relief materials is one of the most important aspects when fighting with a natural or a man-made disaster. Due to the sudden and urgent nature of most disasters, it is hard to make the exact prediction and projection on the demand information. Meanwhile, timely delivery is also a problem. In this paper, we take the war against COVID-19 as an introductive example, analyze the process of material distribution hosted by a government department. We first show a fuzzy decision-making method to proper evaluate the demand degree of each hospital, then based on the result of it, we propose a mixed distribution model to improve the efficiency of delivery. Finally, we carry on a numerical experiment and compare results with the original way that adopted by the government.
