Integrated temporary facility location and casualty allocation planning for post-disaster humanitarian medical service.

• Developing a novel integrated medical facility location and allocation planning model. • Proposing a bi-objective model. • Providing an iteration method to obtain the Pareto front efficiently. • Numerically comparing our method and the binary search method and providing managerial insights. The planning of temporary medical service facility location and the distribution of casualties to these facilities require to consider casualty triage, health deterioration conditions, and equitable distribution of limited medical resources. The paper develops a bi-objective optimization model to determine the optimal temporary medical service locations and medical service allocation plan by maximizing the number of expected survivals and minimizing the total operational cost in the way of using ambulances and helicopters. Based on ∊ –constraint method, we propose an iteration method to obtain the Pareto front of the bi-objective optimization model. Sensitivity analyses are conducted to provide helpful managerial insights. [ABSTRACT FROM AUTHOR]
