摘要:

我们解决的问题定位设施的$[0,1]$间隔的基础上,从战略代理的报告。每个代理的成本是她到最近设施的距离,全局目标是最小化代理的最大成本或社会成本。相对于广泛的文献设施的位置,认为乘法误差,我们专注于最大限度地减少最坏情况下的附加误差。最小化附加误差激励机制适应实例的大小。也就是说,这种机制在小的实例中可以牺牲很少的效率(所有代理彼此相对接近的位置配置文件),以便在大的实例中获得更多的[绝对]效率。我们认为,这种措施是更好地适合在各个领域的设施选址问题的许多表现形式。我们提出了紧边界的机制定位一个单一的设施在确定性和随机的情况下。我们还提供了几个扩展来定位多个设施。

英文摘要:

We address the problem of locating facilities on the $[0,1]$ interval based on reports from strategic agents. The cost of each agent is her distance to the closest facility, and the global objective is to minimize either the maximum cost of an agent or the social cost. As opposed to the extensive literature on facility location which considers the multiplicative error, we focus on minimizing the worst-case additive error. Minimizing the additive error incentivizes mechanisms to adapt to the size of the instance. I.e., mechanisms can sacrifice little efficiency in small instances (location profiles in which all agents are relatively close to one another), in order to gain more [absolute] efficiency in large instances. We argue that this measure is better suited for many manifestations of the facility location problem in various domains. We present tight bounds for mechanisms locating a single facility in both deterministic and randomized cases. We further provide several extensions for locating multiple facilities.
