Locate vaccination stations considering travel distance, operational cost, and work schedule

•A multi-objective mixed integer nonlinear programming (MINLP) model is proposed to locate vaccination stations.•A two-stage strategy is developed to simplify the MINLP model into a MILP model so as to solve a real-life case.•ε-constraint method is used to obtain Pareto non-inferior frontier and provide good solutions for well trading off among multiple objectives.•The research results really help the CDC (Center for Disease Control and Prevention) in decision making.
