Fuzzy model set cover problem of optimal location of emergency departments in Palembang based on technique for order preference by similarity to ideal solution method with some criteria

This research was conducted to determine the nearest hospital that has Emergency Department (ED) facilities in each district of Palembang City. The research objective is to design the optimal location of ED facilities in Palembang with criteria involving the type of hospital and the number of general practitioners in hospitals. Gojek application to find the cost of public transportation from districts to hospitals with ED facilities. Then, this study discussed the optimal location of hospitals with ED facilities in Palembang City with the fuzzy set cover problem (SCP) models based on the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. Fuzzy SCP models solved by the TOPSIS method solve problems in selection or ranking based on several criteria. The most optimal ED location is visited based on mileage criteria, travel time, hospital type, and public transportation costs. The results obtained at the optimal location in each district in Palembang City are different. One of the results were the order of hospitals’ location that have the most optimal ED facilities visited by people from Alang-Alang Lebar District, namely RSU Muhammad Hoesin – RSU RK Charitas – RSU Palembang Bari – RSK Ernaldi Bahar – RSU Bunda.
