Objective In order to establish a drug supply security system standard and meet the management system need of drug circulation enterprises, we studied the pharmaceutical distribution optimization problem to reduce the cost of medicine circulation and improve the efficiency of the pharmaceutical supply chain, which includes analysis of the requirements of the hospital market, forecasts and the location of the pharmaceutical distribution centre.
Methods An ELSON location model based on flow is constructed to quantitatively analyze the relationship between logistics and non-logistics elements of the drug distribution centre. A method based on linear tables and a process to determine the distribution centre of the pharmaceutical distribution unit is proposed. The EIQ analyzis method is proposed to analyze the number of drugs and the rules of mining.
Results The results show that the trends in efficiency and stability were roughly stable after the proposed quantum ant swarm algorithm was executed 100 times, but the trends fluctuated more when the other three algorithms were used. The solutions were also better with the other algorithms.
Conclusions This research provides theoretical support and guidance for the optimization and management of the logistics systems of pharmaceutical distribution enterprises, which can effectively reduce the cost and improve the efficiency of medicine circulation.
