Locating Emergency Warning Sirens
研究将集合覆盖和最大覆盖选址模型应用于美国中西部城市紧急警报器的选址，分析不同政策选项的成本影响，发现这些模型能有效节省成本。
ABSTRACT In this paper, we report on the application of set covering and maximal covering location models to the problem of locating emergency warning sirens in a midwestern city. Two siren types are available, each having different costs and covering radii. Using a modified version of the set covering location model, we analyze the cost implications of several policy options being considered by the city's planners. Results of the study indicate that location covering models can be powerful and efficient tools in the design of such systems, and their use can lead to significant cost savings. In addition, such models provide decision makers the flexibility to examine the inherent costs associated with various policy options.
