Covering-Location Models for Emergency Situations That Require Multiple Response Units
提出一种新的覆盖准则，适用于需要多辆消防车或救护车才能满足需求的应急场景，并基于集合覆盖和最大覆盖问题建立模型，报告了初步计算经验。
In this paper we propose a new criterion for coverage which is suitable for two kinds of applications: (i) location of fire trucks in a geographical area in which some demands require multiple fire trucks to be within an acceptable distance standard to achieve coverage; and (ii) location of ambulances in an environment in which a large demand volume often leads to the unavailability of the most desirable response unit. The set covering location problem and the maximal covering location problem are examined in the proposed modeling framework. Properties for these models are developed, and limited computational experience is reported.
