Obnoxious facility location: the case of weighted demand points

The problem considered in this paper is the weighted obnoxious facility location in the convex hull of demand points. The objective function is to maximize the smallest weighted distance between a facility and a set of demand points. Three new optimal solution approaches are proposed. Two variants of the "Big Triangle Small Triangle" global optimization method, and a procedure based on intersection points between Apollonius circles. We also compared the results with a multi-start approach using the non-linear multi-purpose software SNOPT. Problems with 1,000 demand points are optimally solved in a fraction of a second of computer time.

令人讨厌的设施位置:加权需求点的情况

本文考虑的问题是需求点凸包中的加权讨厌设施位置。目标函数是最大化设施点和一组请求点之间的最小加权距离。提出了三种新的最优解方法。“大三角小三角”全局优化方法的两种变体,以及一种基于阿波罗尼乌斯圆之间交点的程序。我们还将结果与使用非线性多用途软件 SNOPT 的多开始方法进行了比较。具有 1,000 个请求点的问题可以在几分之一秒的计算机时间内得到最佳解决。
