Abstract
Background and objectives：Resulting from more concern about threats of Stomach Cancer, Colorectal Cancer and the strong promotion of Colon Cancer Screening by health sector, the demand for Gastroscopy and Colonoscopy rises rapidly. With more demand, health providers have to face the management issues of capacity planning, utilization measurement, and cost control more carefully when they plan to increase their supply. In a complex service system, it’s quite difficult to figure out a better resource allocation under complicated interaction driven by resources through the study of single factor. Therefore, this study aims to improve efficiency of gastrointestinal endoscopy procedure through the research upon resource allocation of thirteen resource factors and hiatus between customers’ arrival simultaneously. The managerial tool provided includes information of resource allocation, appointment system, and cost structure.ethod：Various theories in the field of operation management and operation research are applied to find out the minimum appropriate volume of resources in gastrointestinal endoscopy procedure, primarily by simulation software and response surface methodology. Under the constraints of waiting time within 20 minutes, resource allocation and appointment system are integrated to complete managerial table and comprehensive analysis given 8 hrs, 12 hrs, and 24 hrs case and six scenarios of 1 to 6 service lines. Finally, the best scenario is found by resource utilization rate and average fixed cost per client in the scenario is shown as well.esult：This study presents minimum resource level under three cases and six scenarios. The results indicate that in both 8 hrs and 12 hrs cases, setting with less than or equal to two service lines could make utilization rate of gastroenterologist more than 70%, and in 24 hrs case, setting with less than or equal to three service lines could make it more than 70%. Additionally, the average fixed cost per outpatient will decline to the lowest amount while setting three service lines for each case.onclusion：While considering the utilization rate of gastroenterologist and the average fixed cost per outpatient, setting with two service lines in both 8 hrs and 12 hrs cases is the best solution and setting with three service lines in 24 hrs case is the best solution.
