厌恶性设施位置:加权需求点的情况

Obnoxious facility location: the case of weighted demand points

Pawel Kalczynski, Atsuo Suzuki, Zvi Drezner

摘要:

本文考虑的问题是需求点凸包中的加权讨厌设施选址问题。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。给出了“大三角小三角”全局最优化方法的两种变型和基于Apollonius圆交点的程序。我们还使用非线性多用途软件SNOPT与多启动方法的结果进行了比较。1,000个需求点的问题在计算机时间的几分之一秒内得到最佳解决。

英文摘要:

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.
