Study On The Model And Optimization Of Surgical Scheduling Problem For Routine Hospitalizations

With the increasing demand for medical resources,the reform of the medical system continues to deepen.In this background,improving the operational efficiency of medical institutions has been highly valued by academic workers and the medical management community.Surgical scheduling is the core content of medical operation management,which is not only related to the vital interests of patients and doctors,but also an important part of hospital operational management.How to maximize the satisfaction of interested parties such as hospitals,doctors,and patients in surgical scheduling is a difficulty in solving surgical scheduling problems.The multi-target surgical planning study not only helps the hospital to strengthen the management of medical resources such as the operating room,but also helps the doctor to arrange the time rationally and reduce the total operation time,so as to avoid the occurrence of medical accidents caused by doctor fatigue.It can also reduce the waiting time before the patient’s surgery,to avoid prolonging the risk of disease progression.Therefore,multi-target surgical scheduling research can improve the satisfaction of various stakeholders in the surgical service,and thus effectively alleviate the conflicts between doctors and patients.For routine hospitalization,surgical scheduling is mainly divided into advance scheduling and allocation scheduling.The advance scheduling is the process of scheduling the surgery date.The allocation scheduling is the process of scheduling surgery room and starting time or surgical sequence and the corresponding medical staff within the scheduled date.When the overall operation scale is large,the advance scheduling should be taken,and when the overall operation is small,allocation scheduling should be performed.In order to systematically solve the problem of surgical planning in hospitals,it is necessary to integrate the study on advance scheduling and allocation scheduling.A variety of factors constrain the form and outcome of surgical planning,including the overall surgical size,operating room,patient priority,uncertainty,surgical pathology type,and physician ability.This article mainly studies the following two issues.Advance scheduling and allocation scheduling model establishment and problem solving.In the context of the relative scarcity of medical resources and the increasingly tense relationship between doctors and patients,it is imperative to conduct humanized and resource-efficient surgical scheduling.In the advance scheduling studies,most of the studies have neglected the effect of the waiting queue length when reducing patient waiting time or increasing the utilization rate of the operating room,and neglected that more cases of surgery can speed up the surgical overall progress.In the study of allocation scheduling,most studies have set the number of operating rooms to be stable rather than decision variables or optimization goals in the optimization of medical service satisfaction,ignoring the opening of fewer operating rooms to help the department to save considerable operating room costs and help hospitals integrate the use of free operating theatres.On the basis of improving the existing research deficiencies,this article aims to establish a mathematical model of advance scheduling and allocation scheduling for routine hospitalizations,and uses an improved non-dominated sorting genetic algorithm to solve the problem,and innovatively proposes the population chromosomes unique mechanism(PCUM)and improved crowding distance operators to improve the performance of the algorithm.Finally,an example study is used to verify the feasibility and effectiveness of the algorithm and model.Advance scheduling and allocation scheduling applying situational differentiation.Most of the existing studies focused on the advance scheduling or allocation scheduling only,which did not systematically integrate the advance scheduling and allocation scheduling and did not clarify the applicable situations.In order to conduct a more comprehensive and systematic study of surgical scheduling,this paper will integrate the study of advance scheduling and allocation scheduling.Through the establishment of the model,it will provide a situation for the medical institution managers to apply advance scheduling and allocation scheduling.
