    Visualizing the demand for various resources as a function of the master surgery schedule: A case study.

    This paper presents a software system that visualizes the impact of the master surgery schedule on the demand for various resources throughout the rest of the hospital. The master surgery schedule can be seen as the engine that drives the hospital. Therefore, it is very important for decision makers to have a clear image on how the demand for resources is linked to the surgery schedule. The software presented in this paper enables schedulers to instantaneously view the impact of, e.g., an exchange of two block assignments in the master surgery schedule on the expected resource consumption pattern. A case study entailing a large Belgian surgery unit illustrates how the software can be used to assist in building better surgery schedules.Assignment; Case studies; Consumption; Decision; Demand; Exchange; Expected; Image; Impact; Management; Operating room scheduling; Resource management; Scheduling; Software; Studies; Visualization;

    Assigning Triaged Patients to Treatment Rooms in a Hospital Emergency Department

    Get PDF
    The assigning of new arrivals at a hospital emergency department to treatment rooms was examined. New patients are summarily triaged and assigned to a treatment room based on severity of their symptoms, the grade of a treatment room, and an exponential benefit curve that encourages the solver to schedule the most severe cases early. SASā€™s OPTMODEL modeling language was employed to build the model and SASā€™s MILP solver was used to perform the scheduling. Up to thirty patients were optimally assigned to depict the example of a large emergency department

    Planning elective surgeries Analysis and comparison in a real case

    This work focus on hospital surgical suite optimization, mainly in the efficient use of the operating rooms when planning elective surgeries. We studied a real case in a hospital in Lisbon. An integer linear programming model was developed to weekly schedule elective surgeries for the hospital surgical suite. The model was tested with real data collected from the hospital records. Non-optimal solutions obtained were improved with a simple and efficient improving heuristic. All solutions have actually improved through this process. These results were finally analyzed and compared with the ones the hospital really performed. The analysis shows that the solutions obtained by our approach improve the use of the surgical suite while respecting the conditions imposed by the hospital. The analysis also shows that the plans obtained by the proposed approach can be implemented

    Nurses Scheduling by Considering the Qualification using Integer Linear Programming

    Get PDF
    One of problems that frequently occurs in hospital management is nurses scheduling problem. A suitable schedule is needed in order to avoid fatigue, both physically and psychologically, which subsequently may deteriorate their performance. Nurse scheduling is commonly designed by the head of nurse manually. In this research, nurse scheduling problem is modeled by considering the qualification of the nurses and the model has the form of integer linear programming. The objective of the model is to maximize the number of nurseā€™s day-offs. Then optimization problem is implemented to nurses scheduling in the High Care Unit and the Emergency room of Rumah Sehat Terpadu Dompet Dhuafa Parung Bogor

    Scheduling surgical cases in a day-care environment: a branch-and-price approach.

    Get PDF
    In this paper we will investigate how to sequence surgical cases in a day-care facility so that multiple objectives are simultaneously optimized. The limited availability of resources and the occurrence of medical precautions, such as an additional cleaning of the operating room after the surgery of an infected patient, are taken into account. A branch-and-price methodology will be introduced in order to develop both exact and heuristic algorithms. In this methodology, column generation is used to optimize the linear programming formulation of the scheduling problem. Both a dynamic programming approach and an integer programming approach will be specified in order to solve the pricing problem. The column generation procedure will be combined with various branching schemes in order to guarantee the integrality of the solutions. The resulting solution procedures will be thoroughly tested and evaluated using real-life data of the surgical day-care center at the university hospital Gasthuisberg in Leuven (Belgium). Computational results will be summarized and conclusions will eventually be formulated.Branch-and-price; Column generation; Health care operations; Scheduling;

    Operating room planning and scheduling: A literature review.

    Get PDF
    This paper provides a review of recent research on operating room planning and scheduling. We evaluate the literature on multiple fields that are related to either the problem setting (e.g. performance measures or patient classes) or the technical features (e.g. solution technique or uncertainty incorporation). Since papers are pooled and evaluated in various ways, a diversified and detailed overview is obtained that facilitates the identification of manuscripts related to the reader's specific interests. Throughout the literature review, we summarize the significant trends in research on operating room planning and scheduling and we identify areas that need to be addressed in the future.Health care; Operating room; Scheduling; Planning; Literature review;

    Scheduling Elective Surgeries in Operation Room with Optimization of Post-Surgery Recovery Unit Capacity

    Get PDF
    Scheduling of surgeries in the Operation rooms with limited available resources is a very complex process. Patients of different specialties are operated by surgery teams in operation rooms and sent to recovery units. In this thesis, we develop a model to help Operation room scheduling management to schedule elective patients based on the availability of surgeons and operation rooms with three phase hierarchical approach of scheduling. A linear integer goal programming method is used to solve problem. The model tries to minimize number of patients waiting for service, underutilization of operating room hours and maximum number of patients in the recovery units. Windsor Regional Hospital help is taken to understand the surgery booking procedure. Lexicographic goal programming method and weighted goal programming is employed and various combinations of priorities are solved to schedule Operating rooms. The focus of the study is to develop mathematical model for scheduling

    A survey of health care models that encompass multiple departments

    Get PDF
    In this survey we review quantitative health care models to illustrate the extent to which they encompass multiple hospital departments. The paper provides general overviews of the relationships that exists between major hospital departments and describes how these relationships are accounted for by researchers. We find the atomistic view of hospitals often taken by researchers is partially due to the ambiguity of patient care trajectories. To this end clinical pathways literature is reviewed to illustrate its potential for clarifying patient flows and for providing a holistic hospital perspective

    Taxonomic classification of planning decisions in health care: a review of the state of the art in OR/MS

    Get PDF
    We provide a structured overview of the typical decisions to be made in resource capacity planning and control in health care, and a review of relevant OR/MS articles for each planning decision. The contribution of this paper is twofold. First, to position the planning decisions, a taxonomy is presented. This taxonomy provides health care managers and OR/MS researchers with a method to identify, break down and classify planning and control decisions. Second, following the taxonomy, for six health care services, we provide an exhaustive specification of planning and control decisions in resource capacity planning and control. For each planning and control decision, we structurally review the key OR/MS articles and the OR/MS methods and techniques that are applied in the literature to support decision making
