摘要:

设施选址问题常常允许设施位于任何位置。但如果实际情况并非如此呢?如果设施只能位于特定位置,如高速公路出口或靠近公共汽车站,该怎么办?我们在这里考虑的影响,这样的限制设施的位置上的性能的策略证明机制定位设施。我们研究四个不同的性能目标:座席必须行驶到其最近的设施点的总距离,任何座席必须行驶到其最近的设施点的最大距离,以及功利主义和平等主义的福利。我们表明,限制设施的有限的一组位置,使所有四个目标更难大致。

英文摘要:

Facility location problems often permit facilities to be located at any position. But what if this is not the case in practice? What if facilities can only be located at particular locations like a highway exit or close to a bus stop? We consider here the impact of such constraints on the location of facilities on the performance of strategy proof mechanisms for locating facilities.We study four different performance objectives: the total distance agents must travel to their closest facility, the maximum distance any agent must travel to their closest facility, and the utilitarian and egalitarian welfare.We show that constraining facilities to a limited set of locations makes all four objectives harder to approximate in general.
