The selection of the location of an emergency medical service (ambulance base) is one of the problems involved in designing a suitable emergency medical service, providing life support for emergency patients, under the timing requirements of the Emergency Medical System (EMS). The objective of this research is to select locations to provide coverage and clustering of service areas (minimum number of bases and maximum coverage). In this research, we use a hybrid method based on the Best-Worst Method (BWM) and Maximal Covering Location Problem (MCLP) for locating emergency medical services, based on a case study of thirty-two candidate locations in Muang Maha Sarakham District, Thailand. The area population, local emergency patients, being close to the communities and main roads, wireless local networks, public utilities and social environment were considered by decision makers. Firstly, BWM was used to calculate the criteria weights and final score. After that, the MCLP model was used to select the suitable emergency medical service locations. As a result, seven emergency medical service locations were selected based on the opinions of decision makers.
