费用最大化的有约束异质两设施选址对策

Constrained Heterogeneous Two-facility Location Games with Max-variant Cost

Qi Zhao, Wenjing Liu, Qizhi Fang, Qingqin Nong

摘要:

在本文中,我们提出了一个受约束的异构设施选址模型,一组替代位置是可行的建设设施和设施的数量在每个位置是有限的。假设真实线路上的一组智能体可以策略性地报告其位置,并且每个智能体的成本是她到她感兴趣的进一步设施的距离,我们研究了受约束的异构两设施位置博弈的无钱确定性机制设计。根据主体是否具有选择性偏好,将问题分为强制性偏好和选择性偏好两种情况。在每个Agent由两个异构设施提供服务的强制设置下,我们分别针对总成本/最大成本目标给出了一个3-近似确定性群体防策略机制,这也是相应社会目标下的最佳确定性群体防策略机制.在可选的设置,每个代理可以在两个设施之一或两者都感兴趣,我们提出了一个确定性的组策略的预防机制与近似比最多为$2n+1$的总成本目标和一个确定性的组策略的预防机制与近似比最多为9的最大成本目标。

英文摘要:

In this paper, we propose a constrained heterogeneous facility location model where a set of alternative locations are feasible for building facilities and the number of facilities built at each location is limited. Supposing that a set of agents on the real line can strategically report their locations and each agent's cost is her distance to the further facility that she is interested in, we study deterministic mechanism design without money for constrained heterogeneous two-facility location games. Depending on whether agents have optional preference, the problem is considered in two settings: the compulsory setting and the optional setting. In the compulsory setting where each agent is served by the two heterogeneous facilities, we provide a 3-approximate deterministic group strategyproof mechanism for the sum/maximum cost objective respectively, which is also the best deterministic strategyproof mechanism under the corresponding social objective. In the optional setting where each agent can be interested in one of the two facilities or both, we propose a deterministic group strategyproof mechanism with approximation ratio of at most $2n+1$ for the sum cost objective and a deterministic group strategyproof mechanism with approximation ratio of at most 9 for the maximum cost objective.
