In competitive settings, firms locate their stores to take advantage of consumers’ behavior to maximize their market share. A common behavior is comparison-shopping: in this behavioral pattern, consumers visit multiple stores that sell non-identical products, which are mutual substitutes, before making their purchase decision. This behavior has never been included in location-prescribing models for competitive firms. Given existing branches of one firm, we address the location problem of a follower firm that locates its own branches. We present insights on the instance used by ReVelle in his maximum capture formulation, provide computational experience with one thousand 100-node instances, and consider a realistic case using a 353-node network of Santiago, Chile. The results are compared in terms of the demand captured by each firm and the locational patterns that result from different consumer behaviors.

比较购物的跟随者竞争性位置问题

在竞争激烈的环境中，公司会选择商店来利用消费者的行为来最大化其市场份额。比较购物是一种常见的行为：在这种行为模式中，消费者在做出购买决定之前会拜访多家商店，这些商店出售互不相同的互不相同的产品。这种行为从未包含在竞争性公司的位置指定模型中。给定一个公司现有的分支机构，我们将解决定位其自己的分支机构的追随者公司的选址问题。我们提供有关ReVelle在最大捕获量中使用的实例的见解公式，提供一千个100节点实例的计算经验，并考虑使用智利圣地亚哥353节点网络的实际案例。根据每个公司捕获的需求和不同消费者行为产生的位置模式对结果进行比较。
