Optimization Research On The Wounded Passing Through Battlefield Medical Aid Stations

Modern war in a sense,is more about logistics.Among the wartime logistical works,medical support is the primary.Medical rescue forces comprisethe main body fulfilling wartime medical support mission,being the final output port of medical resources and the fulcrum of battlefield health service.Large-scale medical rescue forces carry out medical support task in the shape of battlefield medical aid stations,which are also the research objects of this study.Firstly,on the base of literature investigation,necessity,feasibility and challenges of the study were systematic analysed,and Conceptual framework was formed.Then we demonstrated the definition,function,and appropriate technology of battlefield medical aid stations which was only a new concept.Asbattlefield medical aid stations does not only refer to a certain kind of medical aid stations,to make the study clearer,we focused on the most typical one,namely,field medical station.Using the achievement of "SOP" study on the mobile medical logistic teams,we described functional unit division and workflow in a field medical station systematically,and selected linear programming mathematical model as the core mathematical model of the study.According to structure of the model,we enumerated all the wounded flows between every two functional units as the decision variables of the model,and established the objective function according to maximization of the quantity of the wounded passing through.All the working procedures in the main medical aid process were the basic elements for the model,and workflows were formed with the working procedures using he network planning technique.Adding time-consuming parameters to the model,we got the parameters by the method of training video analysis and questionnaire survey.Thus we achieved the critical paths of different treatments,where a single wounded was treated,and the time consumed.Depending on that,simple linear relationshipsamong decision variables and the number of beds,operating tables and staffs could be expressed by equalities orinequalities,which were constraints of the model.Win QSB linear programming module was used to solvethe mathematical problem.It turned out that,on the premise that the evacuation capacity could ensure a quantity of 400 passengers per day,the amount of the theoretical maximum value of the wounded passing through a typical battlefield medical aid station was 302 per day.To reach this goal,surgical group need to operate all the time,and all the surgical patients were sent from triage and evacuation group directly.No wounded flow between two groups was permitted,and staffs in serious injury treatment group and residential treatment groups were all busy.At the same time,there were 36 mobile beds,which can be used for the wounded stay treatment and infectious disease isolation without affecting the overall wounded passing through.According to the conclusion of our model,here are the suggestions.First,command group and triage and evacuation group should pay more attention to cooperation and fine degree in working.Second,in further training,the organization model needed to be innovated,including all the factors,and comprehensively improved the degree of real combat.Third,enhance the staffs’ conception of cooperation,take the initiative to improve accuracy of classification and timeliness of treatment,and communicate actively,adjusting the allocation of beds and the division of personnel rationally,reducing unnecessary patient transferring between groups.
