In this paper we propose a simple general framework for obtaining facility dependent distance decay function in competitive location models. As the distance increases, the decay in patronage by more attractive facilities is slower than the decay by less attractive facilities. This implies that by using only the distribution patterns of neighborhoods from which facility’s patrons originated, the facility dependent decay approach implicitly accounts for the varying degrees of facilities’ attractiveness. No modifications are required in order to apply existing solution algorithms to the new model. The effectiveness and accuracy of the new approach is demonstrated using a real data set.

在本文中，我们提出了一个简单的通用框架，用于在竞争性位置模型中获得与设施有关的距离衰减函数。随着距离的增加，更具吸引力的设施所产生的光顾衰减要比缺乏吸引力的设施所造成的光衰减慢。这意味着仅通过使用设施主顾所来自的社区的分布模式，依赖设施的衰减方法就隐含了不同程度的设施吸引力。无需进行任何修改即可将现有的求解算法应用于新模型。使用真实数据集证明了新方法的有效性和准确性。
