Abstract: We study a service center location problem with ambiguous utility gains and uncertain demand. The model is motivated by the problem of deciding medical clinic/service centers, possibly in rural communities, where residents need to visit the clinics to receive health services. A resident gains his utility based on service features such as travel distance and waiting time at the facility that depend on the clinic location. The elicited location-dependent utilities are assumed to be ambiguously described by an expected value and variance constraint.
