Innovative contribution of this study
Stage of the epidemic
The assumptions of the model were not consistent with the demand for medical supplies in the early stage of the epidemic, and the dynamic characteristics of the demand for medical materials at the initial stage of the epidemic were not fully considered
In this study, the optimal model of medical supplies stowage is constructed by integer programming, aiming at the characteristics of a relatively concentrated epidemic area, relative lack of medical supplies at the epidemic point, and obvious rising trend of demand for all kinds of medical supplies
Traffic control
They failed to fully consider the impact of traffic control in the early stage of the epidemic on the time when emergency supplies can be put into use
Based on the BPR function, the impact of traffic control on road traffic was analyzed, and then the impact of traffic control on travel costs with the development of the epidemic was calculated. According to the road impedance function, the specific cycle in which medical supplies can be put into use is analyzed
Stowage optimization object
The existing literature mainly studies the optimal allocation scheme of medical supplies that have been delivered to epidemic sites among different users
The demand for different kinds of medical supplies at the epidemic point was predicted, and the optimal loading model of emergency medical supplies for the rescue point was established
