APPLICATION OF DISCRETE-EVENT SIMULATION AND EXPERIMENTAL OPTIMIZATION DESIGN FOR HEALTHCARE RESOURCES-YOZGAT BOZOK UNIVERSITY RESEARCH AND APPLICATION HOSPITAL

Öz

Hospitals are the most important structures in healthcare systems. The emergency services are the most important units of hospitals and the patients mostly enter the hospital from these units. For this reason, emergency units are important in terms of healthcare management. This study has aimed to increase the number of patients treated in the emergency department, to decrease the patient waiting time, to reduce the time that the patient should spend in the emergency department, and to maximize the efficiency of the resources by using the data of the emergency department of Yozgat Bozok University Research and Application Hospital. The methodology of this study consists of three main stages. In the first stage, a discrete-event simulation model belonging to the emergency department was created. The second stage of this study, design of experiment which includes all combinations of decision variables belonging to the simulation model whose validity was tested, was created. The third stage of the study, optimization models, were developed by performing statistical analysis of the results obtained from the design of experiment and simulation models. Considering the maximum and minimum values of the decision variables in simulation and design of experiment optimum results for the aims of the research and the decision variables were obtained.

SAĞLIK KAYNAKLARI İÇİN KESİKLİ-OLAY SİMÜLASYONUN VE DENEYSEL OPTİMİZASYON TASARIMININ UYGULANMASI-YOZGAT BOZOK ÜNİVERSİTESİ ARAŞTIRMA VE UYGULAMA HASTANESİ

Öz

Sağlık sistemleri içerisinde yer alan en önemli yapılar hastanelerdir. Acil servisler ise hastanelerin en önemli birimleri olmakla beraber hastaların çoğunlukla bu birimden hastaneye girişleri gerçekleşmektedir. Bu sebeple acil servis birimleri sağlık yönetimi açısından önemlidir. Bu çalışma için Yozgat Bozok Üniversitesi Araştırma ve Uygulama Hastanesinin acil servis birimine ait veriler kullanılarak acil serviste tedavi edilen hasta sayısının arttırılmasını, hasta bekleme süresinin azaltılmasını, hastanın acil serviste geçirmesi gereken sürenin azaltılmasını ve kaynaklara ait verimliliğin maksimum seviyeye çıkarılması amaçlanmıştır. Bu çalışmanın metodolojisi üç ana aşamadan oluşmaktadır. İlk aşamada acil servis bölümüne ait kesikli-olay simülasyon modeli oluşturulmuştur. Geçerliliği test edilen simülasyon modeline ait karar değişkenlerden oluşan tüm kombinasyonları içeren ve bu çalışmanın ikinci aşaması olan deney tasarımı modeli oluşturulmuştur. Deney tasarımı ve simülasyon modellerinden elde edilen sonuçların istatistiksel analizi gerçekleştirilerek çalışmanın üçüncü aşaması olan optimizasyon modelleri geliştirilmiştir. Simülasyon ve deney tasarımında ele alınan karar değişkenlerin sahip olduğu maksimum ve minimum değerler göz önünde bulundurularak araştırmanın amaçlarına ve karar değişkenlere ait optimum sonuçlar elde edilmiştir.
