本文研究了可靠的无容量限制的固定充电位置问题（RUFL），设施受到空间相关的中断发生与位置相关的概率（由于自然或人为灾害等原因）。如果一个设施失败，其客户被转移到其他设施，并产生额外的运输成本。我们开发了一个连续近似（CA）模型，以最小化正常和故障情况下的初始设施建设成本和预期客户运输成本的总和。本文提出了如何制定相邻设施中断之间的相关性，并将这种相关性纳入CA模型。数值实验表明，该模型可以用来优化设施的位置设计，以及如何影响系统的总成本的相关性。(C)2009爱思唯尔有限公司保留所有权利。
This paper studies the reliable uncapacitated fixed charge location problem (RUFL) where facilities are subject to spatially correlated disruptions that occur with location-dependent probabilities (due to reasons such as natural or man-made disasters). If a facility fails, its customers are diverted to other facilities and incur excessive transportation cost. We develop a continuum approximation (CA) model to minimize the sum of initial facility construction costs and expected customer transportation costs under normal and failure scenarios. The paper presents ways to formulate the correlation among adjacent facility disruptions, and incorporates such correlations into the CA model. Numerical experiments are conducted to illustrate how the proposed model can be used to optimize facility location design, and how the correlations influence the total system cost.
