In this paper the hierarchical location problem of urban disaster prevention and mitigation facilities is put forward and classified. This hierarchical location problem is modelled in both types, in which higher-lower level facilities are relatively independent and mutual subordinate respectively. According to the characteristic of urban disaster prevention and mitigation facilities location problem, a two-stages process of hierarchical location is presented as follows:(1) location set covering model is used to determine the necessary minimum numbers of facilities and its locations, that can cover all demanded points and be taken as the basic-level facilities; (2) for the independent type of hierarchical location problem, the maximal covering criterion is used to determine the locations of high-level facilities, for the subordinate type of hierarchical location problem, the minimum sum criterion is used to determine the locations of high-level facilities. The application of the model of hierarchical location problem is also discussed.

Objective:To design a simulative model for the forecast and optimal placement of mass casualty evacuation assets.Methods: An operation research module named the location selection problem was introduced in this study.The probabilistic location set covering problem was chosen as the theoretical model for optimal placement of mass casualty evacuation assets.Several indeterminate factors were analyzed in details,including the availability;capacity and velocity and effective work time of evacuation assets.The ideal statistical distributions were determined by the characteristics of these variables.Results: According to the principle of Monte Carlo simulation and based on the probabilistic location set covering problem,random numbers fitting theoretical probabilistic distributions were generated to simulate those indeterminate factors,based on which a simulative model for optimal placement of casualty evacuation assets was designed.Conclusion: This simulative model may be used as a basis for further development of a computer-assisted program and as a reference for medical administration commanders at different levels.
