Embodiment Construction
[0073] Specific examples are given below to further describe the technical solution of the present invention in a clear, complete and detailed manner. This embodiment is the best embodiment on the premise of the technical solution of the present invention, but the protection scope of the present invention is not limited to the following embodiments.
[0074] A method for optimizing a hospital automatic drug distribution system, comprising the following steps:
[0075] S1: Divide the environment of the hospital's automatic drug distribution system into a normal demand environment and an emergency demand environment;
[0076] S2: Solve the nested queuing model under the normal demand environment by the second-order approximation method: apply the model to the drug demand process, drug preparation process, and drug transportation process under the normal demand environment, and establish corresponding queues in each process. The arrival time obeys the general distribution, and t...

The invention relates to an optimization method of an automatic hospital medicine distribution system. The method comprises the steps that the environment of the automatic hospital medicine distribution system is divided into a normal demand environment and an emergency demand environment, a nested queuing model under the normal demand environment is solved through a second-order approximation method, and the nested queuing model under the emergency demand environment is solved through an aggregation approximation algorithm. The accuracy of the analysis model is verified through simulation, bottleneck resources of the automatic medicine distribution system are found, the medicine distribution process is improved, and the interaction mode between a pharmacy and a medicine transportation AGVis optimized. According to the invention, by constructing the nested queuing network model, each link is analyzed quantitatively and the system performance is evaluated, bottleneck resources influencing the waiting time of a patient are convenient to find, the medicine distribution process is improved, and the interaction mode between a pharmacy and a medicine transportation AGV is optimized.
Description
technical field [0001] The invention relates to the field of management science and engineering, and more specifically relates to an optimization method for a hospital automatic drug distribution system. Background technique [0002] The efficiency of drug distribution within a hospital has a greater impact on patient satisfaction, therefore, drug distribution is considered to be one of the most important activities in a hospital. For a long time, there has always been the problem of mixed flow of people and goods in the way of drug distribution in hospitals. Most of the drug distribution uses a combination of full-time delivery teams, trolleys and multiple elevators. This mixed transportation mode of people and logistics not only increases It increases the risk of disease infection and transmission, and increases the workload of medical staff. The hospital is a place where the flow of people and materials is very concentrated. Once encountering a period of high incidence o...
